Demister Mounted on SAR Tower

Checks Corrosion, Keeps Air Clean

Another major facility in the
Company's multi-million dollar
Environmental Control Project
got underway recently with the
installation of a Demister for the
Sulfuric Acid Regeneration Plant.
This project called for the
mounting of a 6'6" diameter by
10'0" high Demister vessel with
a heavy-duty Teflon mist elimi-
nator on top of the Acid Plant
Absorber Tower, to reduce the
mist carry-over to the Acid Plant
stack and from there to the
Up to this time, the acid mist
had been severely corroding the
47-inch duct between the ab-
sorption tower and the fume
abatement stack, and also the
850 tank series which are situat-
ed downwind from the stack.
The deterioration of this duct

had heretofore required exten-
sive repairs and costly replace-
ment and had prevented the
shutdown of the disposal fur-
The new mist elimination fa-
cilities consist of a stainless
steel vessel, manufactured by
York Separators Inc., which
was installed between the ab-
sorber tower and the 47-inch
duct leading to the fume abate-
ment stack.
The process engineering work
on this project was handled by
Bruce G. Frenzel, the mechani-
cal design work was done by
K. T. Wong, while the actual in-
stallation work was performed
by Mechanical personnel of the
Construction & Turnaround/Faci-
lities Division, under the super-
vision of T. V. Ruiz.

A Visit to the Largest Cave in the Antilles

(Continued from page 1)
John B. Opdyke of Lago's Me-
chanical Department (an annuit-
ant since 1965), six boyscouts
and a College student. Together
they explored the cave three
times in a total of seven hours.
The Dutch scientist is probab-
ly the first and only person to
prepare a map of the floor plan
of the impressive cave.
As he considered his work
unfinished, Dr. Hummelinck re-
turned to Aruba earlier this
month (August 6-10) to make a
final survey of the cave so that
he can prepare a cross-sec-
tional map. Dr. Hummelinck
feels that such a map tells more
about the cave by showing its
actual characteristics. This time
he was assisted by Dutch Ar-
cheologist Drs. E. H. J. Boerstra
of the Leiden University in Hol-
land who is on a three-year as-
signment here for STICUSA
(Dutch Institute for Cultural Col-
laboration) to make archeologi-
cal investigations in Aruba.
Dr. Hummelinck plans to pub-
lish his recent findings in the

"New West Indian Guide" of
which he is co-author and chief
editor. This is a 50-year-old pe-
riodical that presents the latest
archeological findings by seve-
ral Dutch scientists in Surinam
and the Netherlands Antilles.
Another purpose of Dr. Hum-
melinck's recent trip to Aruba
and the other islands of the An-
tilles is to determine if there is
sufficient interest for his publi-
cation. The "New West Indian
Guide" has a limited number of
subscribers and for this reason
must rely on the assistance of
several science-oriented organi-
In a short interview with the
staff of the Aruba Esso News,
the Dutch scientist, who was a
guest of Lago's Dr. Beerman
during his recent 4-day stay here,
mentioned that he had made
nine major trips to the Nether-
lands Antilles beginning in 1930.
Following is a reprint of an ar-
ticle which appeared in the Aru-
ba Esso News of August 27,
1955 based on Dr. Hummelinck's
findings in 1955.

The descent into what is popularly known as the Lago Colony
Cave is usually negotiated by climbing down two rambeshi trees
(bumelia obovata) that grow in the fissure of the coral limestone
rock. Once safely at the base of the two trees, the sub-surface vi-
sitor is at the entrance of the rather complicated system of caverns
of the cave.
The visitor to the Lago Cave enters what is by far the largest cave
in the Netherlands Antilles. Previous "explorers" may never have
realized that they traversed passages of about 1500 feet from the
entrance to the most remote point. The shortest distance between
the most extreme points is approximately 2500 feet.
By comparison, the Lago Colony Cave exceeds the Cave of Gua-
darikiri and the well-known cave of Hato in Curaqao by some 1000
feet. These two caves, though much more impressive in other res-
pects, do not exceed 500 feet.
One may wonder whether many people know what lies hidden
behind the fences south of Fourth Avenue. Chances are no one
knew the cave to be the largest in the Netherlands Antilles.
The Lago Cave is very suitable to study certain cave phenomena.
Cave pearls (pesoliths), terraces and basins (gours) can be found
and in several localities stalactites and stalagmites are still in the
act of formation. On these islands these that make up the Ne-.
therlands Antilles this is relatively rare.
The findings were the result of a seven-hour survey. With only
a hand-compass with which the estimations were made for a map,
the passages were explored.
The direction of the main passages follow the fissures (openings)
that pervade the limestone terraces upon which Lago Colony has
been built. The sizes of the openings in the passages are fissures
that have been widened by the dissolving action of the cavern wa-
ter at a time the limestone plateau had hardly emerged above sea
level. Its caves were consequently filled with ground water.
The coral limestone landscape of these islands bears several le-
vels where networks of caverns may be formed. The cavern water
years ago must have remained at levels corresponding to the sea
levels during the time the island, by fits and starts, emerged from
the sea. This all took place untold years ago after its last great sub-

mergence. This can be observed at almost every limestone escarpme
tous face of a ridge or slope). It is also visible in the low-lying limestoi
where the cavern water has pushed aside the sea water and is often
in balance with it.
In several holes and fissures that reach the watertable as far as
the shore oscillations of the water surface may be observed. These
(rise and fall) must be associated with the tide as, for instance, is sh
Magna Cora Well. Most of the passages in the Lago Cave continue i

di e dos palonan, e bishitante bao terra ta na entrada di e sistema
complicA di hanchinan di e cueba.

E bishitante di a cueba ta drenta den loque ta considerS como e
cueba mas grand den Antillas Neerlandes. Exploradornan anterior
podiser no a realize nunca cu nan tabata cruza hanchinan di mas
of menos 2500 pia.

Na comparacion, a cueba di Lago Colony ta surpass e Cueba di
Guadarikiri y a tan conocido Cueba di Hato na Curaqao cu mas of
menos 1000 pia. E dos cuebanan ski, cual den otro respect ta
much mas impresivo, no ta pasa 500 pia.

Un pregunta ta cu si hopi hende sabi kiko ta scondf bao di e

di skerpi ta mas of menos 16 te 20 pia ariba vioer di e skeer. Den
e parti mas pa zuid tabatin dos bentana natural na mas of menos
10 pia.

Vloer di e cueba na algun lugar e no ta cubri cu druipsteen
generalmente ta consisti di un terra fini, seco, color scur cu ta
bira un klei cu ta slip ora e muha. Probablemente en coneccion cu
cobamento di e promer y segundo poos, geet a word traha den
parti nord di e cueba cual nunca a hunga un parti important den
sistema di e cueba. Den e corredornan aki e fondo di a cueba a
sak uno of dos pia den reciente anjanan much mas cu den
hopi otro partinan di e cueba cual a move pa mas hopi algun

Algun skeer small ta yega leeuw bao di e cueba. Tambe ta in-
teresante pa nota cu fondo di e skeer small na banda zuidwest ta
consisti di terra un poco grof. Esaki por haci hende yega na a
conclusion cu despues di yobida awa ta word admit ski.

E scarsedad di animal den e cueba ta remarkable. E awa den e
cueba no a word studio. No ta impossible cu e tin un sorto di
bestia chikito cu casca bros ta bibs aden. E animalnan aki a
word hayS den e poos di Mangel Cora y na algun otro lugar bao
terra ariba e isla.

Un gran cantidad di cocoloshi di terra a acumula den partinan
keto di a cueba. E dos clasenan mas conoci di Aruba, cocolishi di
cabrito y cocolishi di carn6. Algun cocolishi bibo di e clasenan aki'
por word hayS den e skerpi entire Savaneta y Dakota. Pero, masha
stranyo, no tin di nan den e cueba di Lago Colony. Un otro clase
di cocolishi di terra cu de vez en cuando hende ta haya den e
cueba ta di un clase cu nunca hende a haya uno bibo na Aruba.
E ta consider un raza morto.

Esakinan ta solamente algun di e tesoronan di naturaleza cu por
words haya bao di terra di Lago Colony den e cueba cu ta di mas
grand den Antillas Neerlandes. Tin tesoro pa tur vista di forma-
cionnan bao terra cu no ta demands un wowo cientifico pa haya
y aprecit. Respeta loque bo mira y no destrui fenomeno di cueba
cu ta delicado. Una vez destrui, nan ta keda destruf pa semper.

Largest Cave in the Antilles


(Continued from page 4)
when it is wet. Probably in connection with the digging of the first
and second wells, trenches have been made in the northern part of
the cave which never played too important a part in the cave's
draining system. In these corridors the cave bottom has been lower-
ed one to two feet in recent years much more than in many other
parts of the cave which have moved at most a few inches.
A few narrow clefts reach far below cave level. It is also interest-
ing to note that the bottom of the narrow fissure towards the south-
west in the farthest reaches of the southern part consists of a rather
coarse sand instead of the finely granulated residual soil. This
leads to the conclusion that fast flowing water is admitted in this
area after rains.
The scarcity of cave animals is remarkable. The cavern water
that has been exposed in the wells has not yet been studied. It is
not impossible that it inhabits the same small crustaceans which
have been found in the Magna Cora Well and in a few other sub-
terranean places on the island.
A great number of landshells were accumulated in undisturbed
parts of the cave. The most conspicuous two species of Aruba, the
cocolishi cabritu (tudora megacheilos) and the cocolishi di carn6
(cerion uva). Living specimens of the latter species appear to be
confined to the limestone region between Savaneta and Dakota.
They were, strangely enough, lacking in the Lago Colony Cave re-
gion. A third species occasionally found in the cave is a large
bulimulid (oxystyla maracabensis) that never has been found alive
in Aruba. It may be considered a recently extinct species.
These are just a few of the treasures of nature that can be found
below the surface of Lago Colony in the cave that is by far the lar-
gest in the Netherlands Antilles. There are treasures for all sights
of subterranean formations that don't take a scientific eye to find
and appreciate. Respect what you see and don't destroy cave phe-
nomena which are vulnerable. Once destroyed, the phenomena is
lost forever.

of Savaneta Camp kicked off a
massive campaign to aid the
island's mentally retarded child-
ren. Carrying the slogan "Ma-
nifestation '73, Let's Help Them
Live Happily", this campaign in-
cludes other activities to assist

ly Handicapped Child which Is
presently constructing a day
care center for these children at
Piedra Plat.
In another action, the Mari-
nes took to the streets of San
Nicolas and Oranjestad on
August 17 and 18, selling tickets
for a special lottery offering
many attractive prizes. The tick-
ets, at FIs. 1 each, were also sold
from house to house. Drawing

Still to come is a sports com-
petition from August 25 through
August 30 at the Savaneta Camp

branches of sports.
The main event of the Ma-
rines' campaign will be a grand
fair at the Savaneta Camp on
August 31, September 1 and 2,
from 3 p.m. to 2 a.m. All the
marines are currently pitching
in to make this fair as attractive
as possible. There will also be
opportunity for dancing at this
fair in the former Savaneta

Retarded Children
Open-Air Theatre with music by

boyscouts and youth groups
are planning to participate in
the 10 km route which will be
held in Oranjestad from August
27-29, and in San Nicolas from
August 28-30.
As in the past, Lago is assist-
ing the Dutch Marines in their
