Simulator assists in

training operators
Preface
The application of computers for process control was
introduced at Lago in the late 1960's with the consoli-
dation of multiple field controlhouses into the Refinery
Control Center and Oil Movements Control Center.
With time, a number of other operations type computer
systems were installed in the refinery. At present, major
facilities are being replaced, renovated or introduced.
The Storehouse has installed a new materials system,
the Laboratory has acquired new computers, the new
TDC 2000 has just been installed in the Utilities Control
Center, some parts of the ROC control system will be
replaced and the OMCC facilities will be improved.
To display the role that computing and automation
plays in the refinery operations, we have planned a se-
ries of articles on that subject to be presented in diffe-
rent issues of the Esso News this year. The following ar-
ticle, the first in the series, deals with the "Process Ope-
rator Training Simulator", a recently installed system in
the ROC designed to assist in the training of process
operators.
A word of thanks goes to Mr. Glen Lungaro, a Refining
Engineer in the Technical Department, who has contri-
buted this article to the Esso News. Glen was the Project
Leader in charge of the Process Simulator acquisition.
Process Operator Training Simulator
Starting in the early 1940's, and spanning a period of
some 15 years, Lago hired and trained large numbers of
national employees in the Lago Vocational School.

Reef islets harbor important tern colonies


For an island that does not enjoy much flora or fauna, it
is surprising to learn that the reef islets immediately off
the Lago Refinery have harbored the largest and most
important tern colonies (locally known as "meeuwchi")
of the entire Caribbean area in recent years. According
to ornithologists, the welfare of the nesting area off the
Lago plant is truly essential for the further reproduction
and continued existence of these terns, especially the
Cayenne tern which only has a limited distribution
worldwide. This nesting area has become even more
important as the breeding populations of some species
have drastically declined in size in the past 15 years.
Besides the Cayenne tern, other species known to be
represented in Aruba are the Roseate-, Common-,
Least-, Sooty- and Bridled terns. The Cayenne Tern
(Sterna Sandvicensis Eurygnatha in Latin) is the most
numerous breeding species in Aruba. In good years,
almost 3.000 pairs often nest in various subcolonies on
several islets. The terns generally arrive in Aruba in
mid-April as they did this year. If no serious
disturbances occur, they start laying eggs in May. The
females lay up to 3 eggs. After about four weeks of

bienestar di e colonia dilanti di Lago ta verdadera-
mente esencial pa e reproduccion y existencia di e
meeuwchinan aki, especialmente pa e especie Cayenne
di cual tin un cantidad limit mundialmente. E colonial

di e otro especienan ta pone un maximo di tres webo.
Despues di mas o menos 4 siman di incubacion y 5


incubation and five weeks of chickfeeding, all the terns
and their young leave the area by early August.

Sometimes, however, the entire breed of the bird colony
is destroyed by egg poachers who arrive on the island to
look for the so-called "booby eggs". These poachers and
other disturbers have caused a rather low breeding
success of the terns in the past. As the eggs have
camouflaging spots and are hidden in shallow nests
scooped from the sand, even walking on those islands
constitutes a danger to the welfare of the terns.
Although a law protecting these birds was established in
Aruba in 1926, 1974 was the first year that law was
advertised and enforced. Now, in cooperation with
STINAPA-Aruba, the police enforce the prohibition of
collection and destruction of the eggs of these birds.
When disturbers or "booby-egg" thieves are discovered,
Lago Security or the government police should be
called. Violators will then be apprehended.
All lovers of nature can cooperate in the conservation of
the Caribbean's most important tern colony, by not
visiting those reef islets during the terns' nesting season.

To recognize outstanding performance among its officers and at the same time stimulate improve-
ment, the Industrial Security Department has initiated an "Officer of the Quarter" program.
Patrolman Gregory Falconi was the first officer to be selected as the "Officer of the Quarter". His
name was engraved on a plaque that is now hung in the Industrial Security headquarters. The
criteria used for selecting the "Officer of the Quarter" is among others: initiative and drive,
quantity as well as quality of performance and maintaining a good departmental image
(uniform, posture, attitude, discipline etc.). At the end of the year, the department will select the

Coal to return as energy source


One objective of the Esso News is to create more under-
standing of the energy related business environment
and the role Exxon plays in such. In conjunction here-
with, the following article has been reprinted from
Exxon News, an Exxon Corporation publication.
*

Earlier this century, coal was displaced by petroleum
and gas as the industrial world's leading fuel. Now,
however, the abundance of coal, its diversity of supply
and its price advantage over oil and gas, suggests that
this trend will reverse and coal will capture a significant
amount of future energy growth.

The United States alone has about 250 billion tons of
coal that can be economically mined with today's
technology. These reserves represent about one-fourth
of the world's known coal reserves and more than twice
the energy in the proven oil reserves of the Middle East.
Although petroleum will remain the most important
source of energy for many years to come, its growth
through 1990 is projected to be only about 1 percent a
year. By comparison, free world thermal coal demand
during this same period is expected to increase at over 3
percent a year with more than three-quarters burned to
generate electricity.

More than 90 percent coal is currently consumed in the
countries in which it is mined, but this is likely to
change. While the United States is forecast to continue
to be self-sufficient in coal and a net exporter, Europe
and the Pacific Rim countries will be increasingly
dependent upon imported coal. With the demand for
thermal coal projected to double by the year 2000,
international thermal coal trade will grow rapidly.
One of Exxon's principle objectives is to become a sign-
ificant producer of thermal coal, both in the United
States and in selected other countries. Initially, the
company is concentrating on securing a diversified re-
source base and developing economically attractive re-
serves, utilizing large-scale, efficient operations, which
incorporate high productivity, safety and environmen-
tal awareness.


United States

Exxon's most extensive coal activities to date are
centered in the United States, where its recoverable coal
reserves total about nine and a half billion tons.
Exxon began acquiring domestic coal reserves in the
mid-1960s. Today, Exxon has coal holdings in
Wyoming, Montana, North Dakota, Texas, Arkansas,
Illinois, Ohio and West Virginia. Last year, total
production was 18.6 million tons, up about one-third
from 1981. The combined production from Exxon's two
large surface mines near Gillette, Wyoming, totaled
nearly 14 million tons and two underground mines in
Illinois produced almost five million tons of coal. Exxon
is also involved in jointly developing another
underground mine near Wayne, West Virginia.

Colombia
The Cerrej6n project, which will eventually be among
Exxon's largest coal operations, is located in northeas-
tern Colombia at El Cerrej6n, on the tip of La Guajira
peninsula. An Exxon affiliate is the mine's operator,
holding a 50 percent interest in the project in associa-
tion with a corporation owned by the Colombian
government.
The Cerrej6n deposits, which will be mined by the
open-cut method to a depth of 600 feet, contain over
1.6 billion tons of high-B.T.U., low-ash, low-sulfur
coal. Production is scheduled to begin in 1986 and in-
crease to an annual rate of about 15 million metric tons
by 1989. Most of the Cerrej6n coal will be exported to
Europe.
Exxon will provide half of the Cerrej6n investment,
which in addition to the mine, will include: an airfield:
a coal loading port on the Caribbean Sea to handle ves-
sels up to 150,000 deadweight tons; and a 100-mile rail-
road to haul the coal to the port.

Europe
Exxon's Dutch affiliate is participating in a joint
venture to construct a coal terminal in Rotterdam. The
terminal is designed for use in distributing imported

The two boilers are currently
being installed at the Power-
house No. 1 construction of the

ject. This $ 30 million project is
proceeding on schedule and is
planned to be completed by the
end of this year.

Carbon ta regresd como fuente di energia


Un di e obhetivonan di Esso News ta pa crea mas com-
prendemento di e ambiente di negoshi relaciond cu
energia y e function di Exxon den tal. En coneccion cu
esaki, e siguiente articulo a wordo reproduce di Exxon
News, un publication di Exxon Corporation.

* * *

Den e afianan anterior di e siglo aki, petroleo y gas a
reemplaza carbon como e combustible di mas impor-
tante den e mundo industrial. Awor, sin embargo, e
abundancia di carbon, su diversidad di provision y su
prijs cu ta dunt ventaha ariba azeta y gas, ta indica cu e
curso aki lo cambia y cu carbon lo capturA un parti im-
portante den aumento di energia.

Estados Unidos so tin alrededor di 250 billion ton di car-
bon cu por wordo explota economicamente cu tecnolo-
gia di awendia. E reservanan aki ta represents mas o
menos un-cuarto di e reservanan conoci na mundo y
mas cu dos biaha e energia den e reservanan proba di
azeta na Medio Oriente.

Aunque cu petroleo lo keda e fuente di energia mas im-
portante pa hopi afia mas, su aumento te afia 1990 ta
project pa ta unicamente 1 porciento pa afia. Pa com-
paracion, e demand di mundo liber pa carbon termal
durante e mesun period ta wordo spera di aumentA cu
mas di 3 porciento pa afia di cual tres-cuarto lo wordo
uza pa produci electricidad.

Mas cu 90% di tur carbon actualmente ta wordo uzA
den e mesun paisnan den cual e ta wordo mina pero
probablemente esaki lo cambia. Mientras cu Estados
Unidos ta auto-suficiente den carbon y tambe un expor-
tador di e product ey, e dependencia di Europa y e
paisnan di Orilla Pacifico ariba carbon importA lo au-
menta. Cu e demand pa carbon termal projectA pa ta
dobbel na afia 2000, e trafico international di carbon
termal lo crece liher.

Un di e obhetivonan principal di Exxon ta pa bira un
productor significant di carbon termal, tanto na


Estados Unidos como otro paisnan select. Pa cuminza,
compania ta concentrando na sigura un base di recurso-
nan diversifica, utilizando operacionnan eficiente y di
gran escala, cualnan ta incorpora productividad halto,
seguridad y atencion pa ambiente.

Estados Unidos

E actividadnan mas extensive di Exxon ariba tereno di
carbon te na e dia di awe ta concentrate na Estados Uni-
dos, unda e reservanan di carbon explotable ta monta
na un total di nuebe y mei billion ton.

Exxon a cuminzA obtene reservanan domestic di car-
bon na mitar di afianan 60. Awendia Exxon tin tenen-
cianan di carbon na Wyoming, Montana, North Da-
kota, Texas, Arkansas, Illinois, Ohio y West Virginia.
Afia pasa e production total tabata 18.6 million ton, un
aumento di un-tercera parti di e production di 1981. E
production combine di Exxon su dos minanan grand
cu ta na superficie cerca di Gillette, Wyoming a suma
casi 14 million ton y dos mina subterraneo na Illinois a
produci casi 5 million ton di carbon. Exxon tambe ta

Volunteer fire fighters

complete training in

foam fire fighting
In April, the members of Lago's Volunteer Fire Brigade
for the first time participated in an advanced course in
fighting fires with foam. The training, which was con-
ducted at the Fire Training Center, was also attended
by several officers of the Government Fire Brigade.

The program consisted of a total of 24 hours of lecture
and field practice and was instructed by Messrs. John
Sine and Fred Linde of the National Foam Systems
Inc., of Lionville, Pennsylvania. The fire fighters were
introduced to the background of foam, its uses, limita-
tions, and its application techniques under fire condi-
tions. The type of foam used is a bubbly substance
especially designed to combat Class "B" fires, that is,
fire caused by flammable liquids such as kerosine, gas-
oline, diesel fuel and crude oil. The frothy substance
covers and extinguishes fires by excluding air from the
burning surface. (Class "A" fires involve wood, cloth,
paper, etc. and are extinguished with water or a special
type of high expansion foam).

Although this was the first time the Volunteer fire
fighters were given a training in advanced "foam" fire
fighting, Messrs. Chin Harms and Wim Brinkman of
Lago's Industrial Security Department had attended
that same course a few years back at Texas A&M Uni-
versity. The National Foam School, a subdivision of
National Foam Systems, conducts this course annually
at that University where over 100 individuals attend
from all over the world, especially from the oil
industry.

With this additional training, Lago's Volunteer fire
fighters will be better equipped to secure the Refinery
against hazardous fires.

for mining three million metric tons a year. The
company is funding a $ 2 million exploration program
at Gloucester to find additional reserves outside the
known mineable areas.
Exxon also has a 25 percent in the Hail Creek coal
project in Queensland and is conducting an exploration
program in the State of Victoria.

Exxon is determined to carry out its coal activities in a
sound and responsible manner. In addition to miner
safety, the company is committed to safeguarding the
physical environment, to protecting and restoring af-
fected areas and to working with local communities to
help mitigate the social and economic impacts of its
activities.

Exxon's worldwide coal profits are modest, but
growing: $ 25 million (estimated) in 1982 up from $ 13
million in 1981. The company believes demand for coal
will continue to grow through the rest of the century.
Thus, coal is viewed as an attractive, growing business
for Exxon.

I Process simulator . (cont frompag 1) I
SWith the first wave of graduates approaching
retirement age. Lago has been hiring more and more
younger workers, resulting in a steadily declining
average experience level.





"The actual
simulation
occurs in
this
simulator
-computer
Right here,"
said
Glen
Lungaro.





Recognizing this trend, Lago Management several years
ago embarked on a program to prepare for the influx of
new personnel. A major part of this program is the in-
creased emphasis placed on all forms of training. The
Process Department, directly affected by this rising
burden of training, searched for more efficient alterna-
tives to the traditional and time-consuming methods of
class room sessions followed by a prolonged period of
apprenticeship.
The most promising alternative proved to be a process
simulator, which is a system designed to assist in the
training of process operators.

Process Simulator

This process simulator, driven by computer-based
models, attempts to duplicate the operator interface
portion of a real process using authentic instrumenta-
tion.

The programmed models in the computer generate
instrument signals that are very similar to those of a real
process unit (e.g. furnace, or a light-ends tower). The
trainee sits before a standard console and reacts to the
signals by making changes (set point adjustments,
pump starts and stops, etc.) and by observing the
results in the form of altered levels, temperatures, flow
rates, and pressures. The effect is much the same as that
of an aircraft pilot sitting in a flight simulator.

Benefits

An obvious advantage of the simulator is the reduced
training time for operators and new engineers. Other
benefits are increased efficiency and better response to
unit upsets, which in turn provide for safer operations.
In addition the trainee will be exposed to real situations
in a simulated form and thereby develop confidence in
handling similar operating conditions on an operating
unit.


Efficiency

A simulator allows the trainee to directly practice and
exercise the skills learned from conventional methods.
It follows that a simulator not only reduces the training
period, but enhances the quality of that training. The
new operators' increased effectiveness allows a closer
approach to targets and constraints.

It is often not clear to the new operator exactly how, for
example, furnace efficiency depends on interactions
among blower pressure, draft pressure, stack damper,
burner configuration, and duty. A simulator-trained
operator benefits from practice on an ideal furnace,
with predictable responses. He directly observes the
results of his manipulations, and more thoroughly
understands how and why real furnaces deviate from
the ideal.

Unit Upsets

The record shows that most unit upsets are caused by
equipment failure and feed contamination. Because it
duplicates the response of a live process, the simulator
provides a practical way to learn through practice how
to deal with and recover from process upsets. The
operator who has experienced many upsets will
recognize the symptoms earlier and take quicker
action to dampen the effects.
Because of common methods and ease of cross-training,
a simulator-trained operator team is more likely to
prevent upsets from seriously affecting downstream
units.
The number of minor upsets resulting in product down-
grades, slop production, or reduced feed rates should
consequently be reduced.

Conclusion

The simulator, while making the teaching process more
effective, does not take the learning process any easier.
It does not eliminate the need for classroom or
on-the-job training. However, it does provide a
teaching process which allows the process operator to
reach the desired level of functional effectiveness in a
much shorter time.


Recently, Lago again conducted a career orientation
program for this graduating class of Colegio Arubano
students.

brated its fifth anniversary with an award presentation to its 11
members. "The rescue team has demonstrated its value during the
past five years by responding to some real life emergencies," said
Bernard Kalis, captain of the team. To keep team members pre-
pared for life saving operations, they yearly receive intensive train-
ing in first aid techniques, fire fighting, light and heavy rescue
operation and the SCBA They also conduct full day training ses-
sions once a month in the refinery where real life emergency situa-
tions are simulated The rescue team uses specialized rescue equip-
ment, including rigging equipment to rescue from high structures,
and a rescue equipment truck to transport victims if an ambulance
is not available ALERT members would also assist fire fighters
during afire emergency if rescue assistance is not required

Bomberos voluntario a sigi curso avanza


Na April, e miembronan di e Brigada di Bomberos Vo-
luntario di Lago pa promer biaha a participa den un
curso avanza den pagamento di candela cu 'foam'. E
entrenamiento, cual a ser teni na e Fire Training Cen-
ter, tambe tabatin participation di varies official di e
Cuerpo di Bomberos di gobierno.
E program a consists di un total di 24 ora di lectura y
practice y a wordo instrui pa Srs. John Sine y Fred
Linde di National Foam Systems Inc., di Lionville,
Pennsylvania, E.U. E bomberonan a hafia information
tocante e historic di 'foam', su uzonan, limitacionnan y
e modonan di aplicacion durante candela. E tipo di
'foam' cu ta ser uzt ta un substancia espumante espe-
cialmente disefia pa combat candelanan di Clase "B",
esta candela causA pa liquidonan cu ta kima, manera
kerosin, gasoline, azeta di diesel y azeta crudo. E sub-
stancia yen di scuma ta tapa y paga candela door di
corta oxygen for di e superficie cu ta kimando. (Can-


delanan di Clase "A" ta envolv6 palo, pafia, papel, etc.
y por wordo pagA cu awa of un tipo especial di 'foam' di
expansion halto).

Aunque cu esaki tabata e promer biaha cu e bombero-
nan voluntario a hafia un entrenamiento avanzA den
pagamento di candela cu 'foam', Srs. Chin Harms y
Wim Brinkman di Industrial Security Department di
Lago a atende e mesun curso un poco ana pasA na
Texas A&M University. E National Foam School, un
subdivision di National Foam Systems, ta conduct e
curso aki tur afia na e universidad ei, unda mas cu 100
hende di tur parti di mundo ta atend6, especialmente di
e industrial petrolero.

Cu e entrenamiento adicional aki, e Brigada di Bom-
beronan Voluntario di Lago lo ta mihor equipa pa si-
gurA e refineria contra candelanan peligroso.

13 operator di diferente division di Process Department a participate den e Process Training
Program recientemente. E program a consist di 3 siman y mei di instruction den klas y algun
siman di entrenamiento den plant. Instruccion a ser duna pa personal di departamentonan
Technical, Process, y Mechanical. Safety Section tambe a duna instruction cu e ayudo di modulo-
nan STIP (Skills Training Improvement Program). Fotonan ariba: Oslin Boekhoudt di Techni-
cal ta dunando information ariba e topico "Temperature and Heat".


SSimulador . ( cont. dipag. 1)
empleadonan local na Lago Vocational School. Cu e
promer olanan di graduadonan jegando e edad di
pension. Lago a emplea mas y mas trahador hoben,
resultando den un declinacion constant di e nivel di
experiencia.
Mirando e tendencia aki, gerencia di Lago various afia
pasa a embarca ariba un program pa prepare pa e
influho di empleadonan nobo. Un parti principal di e
program aki ta e enfasis creciente cu ta ser poni ariba
tur forma di entrenamiento. Process Department, di-
rectamente afectr pa e carga di entrenamiento a busca
alternativanan mas eficiente pa e metodonan tradicio-
nal di ensefianza den klas sigi pa un period prolongA di
practice.
E alternative mas prometedor a keda comproba di ta e
process simulator', cual ta un sistema disefiA pa asisti
na e entrenamiento di operadornan.
'Process Simulator'
E 'process simulator', stimuli pa modelonan di compu-
ter, ta intent di duplica e parti cu ta toca e operator
den un process real uzando instrumentonan autentico.
E modelonan programA den e computer ta genera
sefialnan di instrumentonan cu ta casi igual na esunnan
cu ta wordo uzA den e process verdadero (por ehemplo,
e forno of e 'light ends tower'). E practicante ta sinta
dilanti unconsola tipico y ta reaccionA ariba e sefialnan,
haciendo cambionan ('point adjustments', 'pump
starts', y 'pump stops') y observando e resultadonan den
forma di nivelnan alter, temperature, 'flow rates', y
presion. E efecto ta mescos cu esun di un piloto di avion
sintA den un simulador di vuelo.
Beneficio
Un beneficio obvio di e simulador ta cu e ta reduci e
duracion di entrenamiento di operator y ingenieronan
nobo. Otro ventahanan ta e aumento di eficiencia y un
mihor reaction ariba trastornonan di e plant, cual na
su turno ta result den operation cu menos peligro.
Adicionalmente e practicante lo word confront cu e
situation autentico na forma simula y cu esei ta desaro-
yA confianza den trata cu situacionnan similar di ope-
racion ariba plant.


Eficiencia
E simulador ta permit e estudiante pa prActicA direc-
tamente y eherce su abilidadnan cual ela sifia pa
metodonan conventional. Ta resultA cu e simulador no
solamente ta reduce e duracion di entrenamiento, pero
tambe ta mehorA e calidad di dje. E aumento den
eficiencia di e operadornan nobo ta permit un mihor
acercamiento di e meta y restriccionnan.
Hopi biaha no ta comprendible pa e operator nobo ta
exactamente con, por ehemplo, e eficiencia di un forno
ta depended ariba e interaccionnan entire 'blower pres-
sure', 'draft pressure', 'stack damper', 'burner configu-
ration' y 'duty'.
Un operator entrena pa e simulador ta beneficial di e
practice ariba un forno perfect cu respuestanan pro-
nosticA. E ta observA di biaha e resultadonan di su
manipulacionnan y ta compronde mihor con y pakiko
un forno real ta desvia di un forno ideal.
Fayonan di Unidad
Record ta mustra cu e fayonan di majoria di unidad ta
wordo causa pa fayo di equipo y contamination. Como
cu e ta duplica e respuesta di un process real e simula-
dor ta ofrec6 un manera practice pa sifia door di prac-
tica ta con ta maneha y recuperA di un fayo di unidad.
E operator cu a experience hopi fayo 1o reconoce e
simptomanan mas tempran y lo por actua mas liher pa
reduci e efectonan. Pa motibo di metodonan comun y e
facilidad di 'cross training', un team di operator en-
trenA pa e simulador lo ta mas capable di prevent un
fayo di afectA e otro unidadnan 'downstream' seria-
mente.
E cantidad di fayonan chiquito cu ta resultA den pro-
ducto di menos calidad, production cu dramamento, of
reduction di e 'feed rate' consecuentemente mester
wordo reduce.
Conclusion
Mientras cu e simulador ta haci e process di entrena-
miento mas efectivo e no ta haci e process di sifiamento
mas facil: E no ta elimina e necesidad pa entrenamiento
den klas of na trabao. Sin embargo e ta ofrece un pro-
ceso di entrenamiento cu ta permit e operadornan di
yega na e nivel di eficiencia funcional desea, den un
tempo mas corto.

I Regreso di carbon . .
ria part di e carbon di Cerrej6n lo
Europa.


(cont. dipag. 5) I
wordo exportA pa


Exxon lo suministrA mitar di e inversion den Cerrej6n,
cu fuera di e mina tambe lo inclul: un pista di aterriza-
he pa avion; un waf pa carga carbon, situA na laman di
Caribe, cu mester por trata barco di peso ta cu 150.000
ton; y un trein cu lo hiba e carbon pa e waf.

Europa

Exxon su afiliado Hulandes ta participando den un
empresa conhunto pa construi un terminal pa carbon
na Rotterdam. E terminal ta disefiA pa distribui carbon
importA, incluyendo carbon di Cerrej6n, pa clientenan
Hulandes y otro clientenan Europeo. E inversion aki ta
un apoyo pa e esfuerzonan di Hulanda pa reduce nan
dependencia ariba petroleo y pa conservA e reservanan
di gas natural pa obhetivonan mas productive.

Canada

Un afiliado di Imperial Oil Limited un compania
Canades den cual Exxon tin un interest di 70% ta dofio
di Byron Creek Collieries kende ta maneha Coal Moun-
tain literalmente un montaila di carbon cu ta sali
ariba tera den parti sureste di British Columbia. Plan ta
wordo desaroyA pa dobbel e production di 1 million ton
metrico di carbon pa afia.


Fuera di e mina aki, e afiliado ta dofio di tenencianan
grand di carbon no-explota den parti oeste di Canada.

Australia

Na New South Wales Exxon tin 49% di interest den un
project di carbon na Gloucester, cual project tin
reservanan cu lo por produci 3 million ton metrico pa
afia. E compania ta subsidiA un program pa
exploracion di 2 million dollar na Gloucester pa asina
busca reservanan adicional pafor di e area conteniendo
carbon.
Exxon tambe tin 25% di interest den e project di
carbon na Hail Greek, Queensland y ta conduciendo un
program di exploracion den e estado Victoria.


Exxon ta determinA pa ehecutA su actividadnan ariba
tereno di carbon na un manera sano y responsible.
Fuera di seguridad den explotacion di minanan,
compania ta determine pa cuida e ambiente fisico,
proteha y restorA areanan afectA y trahA cu comunidad-
nan local pa juda alivid e impact social y economic di
su actividadnan.

Exxon su ganashi mundialmente riba tereno di carbon
ta modesto, pero creciendo: 25 million dollar na 1982,
mientras cu e tabata 13 million dollar na 1981. E
compania ta kere cu e demand pa carbon lo sigi
aumenta pa resto di siglo. Pesei carbon ta wordo mirA
como un negoshi atractivo y creciente pa Exxon.
