Advanced Process Control Career Summary
Exxon Research & Engineering Co.: 17 years conceiving and implementing true
cutting-edge advanced computer controls.
Nine years in key field implementation leadership roles onsite at four
major international plants. Was Exxon's
main Advanced Control and Online Process Optimization consultant to all plants,
on all units.
Authored highly practical and heavily used Exxon "bibles" on
Model-Based Control and Optimal Multi-Blend Quality and Inventory Control, and
strategies for Online Plant-wide Optimization – all based on much field
implementation experience. Created and
taught popular Advanced Control Applications Training Course attended by over
350 already-experienced Exxon computer control engineers, worldwide, in both
Chemicals and Refining. Was chief
company designer of tools for Advanced Applications Engineer training, online
and offline process identification and loop tuning, robust Model-Based Control,
and LP-Based Multivariable Control. Created and successfully
field-implemented Exxon's first fully-closed-loop, plant-wide optimization
project, at Rotterdam.
ProControl, Inc.: founded the company 8/86. Forty-five major corporate clients now use
ProControl's education and software to improve performance and returns from their
Control Engineers, Process Engineers, Instrument Technicians, and Process
Operators.

Achievements and Awards
Exxon Corp. "Outstanding Technical
Achievement" award for creating the Dynamic Reconciliation Model-Based
Control technology now widely used in every Exxon petrochemical plant. (This was a highly prestigious, seldom-given,
and rewarding accolade.)
U.S. Patent 3,781,533: "Constraint
Control System for Optimizing Performance of Process Units".
National Council of Teachers of English Award
for skills with the English language.
National Merit Scholar (now termed a Finalist).
Some Exxon Career "Specifics":
COMPUTER CONTROL SOFTWARE
-- Simplified
dynamic process analysis with a powerful PC-based dynamic modeling
package. Distributed
this package to all Refining and Chemicals sites, at Exxon affiliates’ request. This package significantly increased both the
rate and quality of advanced applications' implementation, and garnered much
affiliate praise. (This tool is a rather
primitive ancestor of ProControl's much more comprehensive and user-friendly
DISCOVER software.) Developed
revolutionary Model-Based, LP-Based control system covering all types of
continuous control problems.
This system literally reduced advanced application implementation times
from months to days. Dr. Bartman was
charged with designing a new control system solely using this approach (in
contrast with use of PID's and classical decouplers),
based on excellent field success and much affiliate demand, when he chose to
leave Exxon. (An enhanced DR Model-Based
algorithm is now included in DISCOVER, and taught via case studies in ProControl's
Revelations Course.)
Played significant role in expanding
the functionality of both Honeywell and IBM process control computer software,
during residency at both HW and IBM plants. Responsible for many
enhancements and bug-fixes before allowing shipment of vendor control systems
to Venezuela and Antwerp.
CONTROL TECHNOLOGY
-- Recognized for "significantly advancing the state-of-the-art in Primary
Fractionator control" while on first field assignment (two years in
Benicia). Designed and implemented
Exxon's first multivariable controls optimizing both crude unit energy
consumption and product yields (in 1970).
Created and implemented Exxon's first online adaptive control and online
Evolutionary Optimization programs; the latter maximized both Light and Heavy
Crude feedrates to the refinery while modifying assumed plant behavior
automatically to conform with reality. A
key feedforward application showed spectacular success in fixing an
"unsolvable" process problem; Exxon Engineering used its strip charts
as a major sales tool to convince other plants to convert from analogs and
pneumatics to digital control. Assumed a
major applications leadership role at this site, and was asked to remain
permanently (but declined).
In one year at the Amuay Refinery in
Venezuela, designed and implemented Exxon Engineering's first optimal online LP
blend control system (1973). Had full
advanced applications team responsibility for this project, which included many
feedforward, constraint and multivariable applications throughout the refinery. Based on
continuing success, was pulled off to lead all applications activities on a
higher-profile project at the Antwerp, Belgium, Plant (1974 - 1977).
Designed and implemented company's largest
multivariable application, optimizing the simultaneous blending of ten grades
of Distillate and Fuel products (Antwerp).
This single application drove the setpoints for 55 flow controllers – a
record within Exxon, and perhaps anywhere, at the time. This highly sophisticated application was
fully implemented within four weeks of the commissioning of the first basic
flow loop in the plant. It was so
immediately successful that the Refinery Scheduling and Coordination staff
deemed it a necessity;
it was not allowed to be turned off thereafter. (The importance of this application had been
properly recognized in earlier applications' goal-setting and manpower
allocation meetings led by Dr. Bartman.)
As part of this large-scale blending
application, implemented the first known use anywhere of a “precursor” LP run
retrieving the Reduced Cost information critical to online intermediate
component pricing, and to Operator Guidance messaging.
While resident at Antwerp (1975 - 1977),
created the Dynamic Reconciliation Model-Based Control technology now employed
over a wide spectrum of process units (Cat Crackers, Hydrocrackers, Hydrogen
Plants, Desulfurizers, Reformers, Towers, Lubes units, Aromatics units, Steam Crackers, …).
Excellent service factors are a common denominator. Antwerp's most advanced applications (e.g.,
online LP optimization of the lowest-cost feed slate to a Hydrogen Plant; many multivariable tower and reactor problems)
showed service factors consistently above 98% overall. One message, stressed heavily in ProControl's
courses: expediency is almost always an
enemy in applications design and implementation. Better to be selective with a
cost/benefit-justified, well-staged implementation plan, and to then do each
application right the first time.
It's no exaggeration to say that Antwerp became the crown jewel among
Exxon's success stories in Advanced Control.
The Multivariable LP-Based technology Dr.
Bartman developed at Antwerp was later judged "best of breed" in
stiff competition with the more complex DMC approach. Exxon later had a portion of this technology
put into DMC.
ONLINE OPTIMIZATION
-- Pioneered Exxon’s first large-scale online plantwide optimization project
(Rotterdam) optimizing key refining operations, from crude feed through product
blending. Designed
all relevant strategies, including both online and offline utilization of
updated process models, and the plantwide dynamic tracking of all stream
qualities required for final product blending. Very successfully led all
field implementation (1980 - 1983).
Designed both online and offline optimization
strategies for all types of product blending, including practical strategies
for intermediate component inventory control.
Included full conformity with Refinery Planning and Scheduling in blend
applications design -- a key point often missed. Excellent online outcomes triggered revisions
in models and strategies both inside and outside the plant – all the way to
Exxon's Corporate Planning level.
EXXON CONTROL EDUCATION
-- Created "Advanced Control Engineer Training" Course providing easy
solutions to many difficult multivariable control problems. This two-week course was taught several times
per year to senior Advanced Control Engineers from all international plants,
both refining and chemical. High student
enthusiasm and follow-through were evidenced by course reviews, and by broad
field implementation of course techniques.
This Advanced Control Course was voted by Exxon in-plant personnel
survey: “The
Best Product Put Out by Exxon Engineering for its Affiliates” two years
in a row. This survey spanned all
Exxon refineries and chemicals plants.
After resigning to form ProControl, Dr.
Bartman was hired back to teach two further Exxon Advanced Control
Courses. He was also hired by a major Exxon
refinery (in direct competition with Exxon Engineering) to revamp its advanced
online blend optimization controls.
