Edgar Diaz, Philip de Souza
Complete Course in Welding
Engineering in the U.S.A.
From June 13 through the 24th, Ed-
gar Diaz and Philip de Souza of La-
go's Mechanical Department attend-
ed a Fundamentals of Welding Engi-
neering Course at the Ohio State
University. Also attending the cour-
se were thirty-eight representatives
from various industries in the United
States.
The course which was taught by
professors of the Ohio State Faculty,
covered basic concepts of metallur-
gy, weld design, modern welding
techniques, heat treatment, welding
process control and non-destructive
inspection with regard to carbon
steel, low alloy and high alloy steel,
aluminum alloys and nickel alloys.
The course consisted mostly of lec-
tures and a few lab sessions.
Edgar and Philip, who returned
with their certificates presented to
them at the University, are very im-
pressed by the efficient and well-or-
ganized manner that the course was
presented by the instructors. Edgar
and Philip both agree that the course
which taught advanced methods and
equipment and latest engineering de-
sign requirements has contributed
considerably to their knowledge of
metallurgy and welding techniques.
Both Edgar and Philip are working
as Mechanical Supervisors for spe-
cial welding jobs, being done in the
refining by Lago and contractor em-
ployees.

Coke Knockout Drum Prevents Gas Release

Abates Noise, Increases Productivity in Decoking


A typical environmental problem
caused by furnace decoking has
been greatly reduced thanks to the
innovation of Emiliano Trimon of the
Combustion Team in Technical Pro-
cess Technical Services.
With the technical assistance of
Leonard A. Peterson of the Environ-
mental Control and Energy Conserva-
tion Group, Emiliano designed a por-
table coke knockout drum which pre-
vents the release of harmful gases,
dust and fumes into the atmosphere
and effectively reduces noise levels
during decoking operations in Pro-
cess Fuels. Decoking is the removal
of carbon deposits in furnace tubes
by forceful injection of heat, air and
steam. The drum, which is easily hoo-
ked up to the furnace decoking out-
let passes, was constructed in the
Mechanical Shops and can easily be
transported with a regular forklift
truck wherever needed.
Previously, the furnace slowdown
lines were closed to about 60% to re-
duce noise during the average 48-
hour decoking period.
The drum permits these lines to
remain completely open, decreasing
unit downtime by approximately 12
hours. At the same time, energy is
saved because less steam and heat
are required to do the job.
The coke knockout drum now ab-
sorbs the gases, fumes and dust and
carries out this waste to the sewage
system and at the same time, sup-
presses the noise by as much as


950/%. The drum also makes it pos-
sible for Lago and contractor person-
nel to work in the area without inter-
ruptions and without having to wear
elaborate protective equipment dur-
ing the entire decoking period.
First used during decoking opera-
tions on No. 5 visbreaker furnace in
March this year, the coke knockout
drum was an immediate success. Its
effectiveness was further corrobora-
ted by our Industrial Hygienist follo-
wing testing and measurements of
gas and noise levels. Since then the
drum has been used successfully on
No. 6, 7 and 8 visbreaker furnaces.
Another drum is being constructed
for the HDS area. The use of the
drum for all decoking operations has

Plasma-Arc Cutting Method Allows Clean Cuts,

Eliminates Time-Consuming Gouging, Grinding


A unique process currently employ-
ed at Lago is obtained with a Plasma-
Arc Cutting machine in the Welding
Shops. The modern equipment, de-
veloped initially for the U.S. space
program and now widely used in in-
dustry, consists of a DC power source
and an arc cutting torch, which uses
CO2, nitrogen or hydrogen/nitrogen.

Unlike other welding equipment,
cutting is not achieved by oxidizing
(burning) metal, but by melting a lo-
calized area with a constricted arc
and removing the molten metal with
a high velocity jet of hot ionized gcs
issuing from the orifice of the torch.
To achieve this, an extremely high
temperature, high velocity constrict-
ed arc between an electrode (tung-
sten) in the Plasma-Arc cutting torch
and the piece to be cut is created.
This process can be used on all me-
tals and alloys in much the same
manner that oxygen (acetylene) cut-
ting is used on mild steel.

Intended for special jobs, the Plas-
ma-Arc equipment eliminates time-
consuming gouging, grinding and
shaping. The welder uses regular
working protective equipment when
operating the machine to cut steel
in any shape or size, bevel plate ed-
ges, pierce holes, do stack cutting
jobs and out-of-position cutting or
areas difficult to reach on refinery
heavy equipment or units.

To employ the machine and get
the most of its time-saving features,
several groups of boilermakers and


welders were trained on its applica-
tion during March and April this year
Whole-day sessions were conducted
by Philip de Souza, an engineering
technician specialized in welding in
Mechanical Maintenance Zone, at
the welding shops where the theore-
tical portion included stripping the
equipment to acquaint employees
with the inner mechanism.

The practical part served to give
the trainees the opportunity to ope-
rate the machine in actual job requi-
rements.

Some of the areas where the Plas-
ma-Arc cutting machine has been

include the fabrication of a 48" dia.
stainless steel expansion joint for
the S.A.R. Plant, 16" dia. stainless
steel strainers for the MIAR Plant,
cutting of stainless steel flanges for
V2AR ammonia injection nozzles and
the removal of 1" dia. Incoloy-800
tubes for the H1AR Plant. On-the-
spot cutting and beveling for weld-
ing a 12" dia. stainless steel pipe in
place was accomplished at H1AR
Plant.

This is an efficient piece of equip-
ment which, besides saving time, al-
so eliminates a previous housekeep-
ing problem and since there is such
a limited heat condition, it creates a
cooler environment resulting in more
comfort for the welder or boilerma-
ker, with little or no distortion of the
materials used.

Ten-Week Course Teaches

Engineers Techniques

In Process Design Work

Fourteen Lago engineers, most of
them fairly recent chemical engineers,
are currently attending a Basic Pro-
cess Design course every Thursday.
The course, which is taught by Lee
N. Stanley of Technical Process
Technical Services, began on June
23, 1977 and will continue every
Thursday for ten consecutive weeks
until August 25 in Classroom 2 of the
Administration Building.
Sponsored by the Process Techni-
cal Services Division, the course was
officially opened by Lago Vice Presi-
dent John R. Gibbs, who stressed
the importance of this course in as-
sisting Lago in becoming a more ef-
ficient and reliable company. Pre-
sent at the opening session was Ray
Farro, Division Superintendent of
P.T.S.
The training program covers the
basic techniques used in handling
refinery process design work and
unit monitoring.
Reference material used in the
sessions include the Esso Blue
Book, basically a refinery operations
"bible", and the Esso Design Practi-
ces Manual. During the 8-hour ses-
sions, the engineers receive lectures
on process units and their functions,
related equipment and instrumenta-
tion, and their safe and efficient ope-
rations, while at each session they
are called upon to work out a pro-
blem on a particular area of unit ope-
ration.
Participants in the Basic Process
Design Course are assigned home-
work. This involves mostly reading
sections from the Blue Book and De-
sign Practices Manual for review in
the next sessions.
The course, which is conducted pe-
riodically for new engineers during a
two-week period, has this time been
given one day a week during ten con-
secutive weeks to afford these em-
ployees more time to carry out their
regular duties more effectively.
This year's participants are: Vic-
tor A. Marval, Bernhard A. Kalis, Ru-
berd A. Barry, Moises F. Kusmus, Ro-
mulo Hernandez, Robert Arrendell
and Donald R. Henriquez of Process
Technical Services; Fouad Younan,
Jose M. Lacld, Erik R. Bruyn and Tre-
vor L. Connor of Mechanical Engi-
neering, Edna L. Farro of Energy
Conservation, Juan Noguera of Pro-
ject Development Division and Rus-
sell H. Dowling from the MCS Divi-
sion.


The above employees navo been selected to attend a fire training course at the Texas
A&M Fire Training School at College Station from August 1 5. Most of them are
members of the Volunteer Fire Brigade, while three are key Process personnel who
play a significant role in refinery fire emergencies. They are shown here with Industrial
Security Administrator Jim Brooke (standing, far right), and Fire Chief Jacinto Harms
