West Coast (Fluor and Jacobs). Area also included GA, SC, NC and TN.
Responsibilities include developing new and resurrecting previous contacts with End
Users and with E&C firms to promote sale of high value pressure vessels, field-erected
tanks, electrical and controls sub-contracts and piping spool and field run piping
sub-contracts. First full year with Enerfab, Inc. resulted in opportunities to quote on
equipment totaling nearly $180 million. Field erected equipment included storage
tanks, storage spheres, carbon dioxide capture towers (80 ft. dia. X 180 ft. tall) 2205
duplex clad, large projects with multiple fermenters (cone bottom, flat-sloped bottom,

such as reactors, distillation columns, drums, heat exchangers, etc.
Jacobs Engineering (Houston, Baton Rouge, Greenville, SC and Calgary)
Lead Process Engineer VI, ChevronPhillips Chemicals, Process design, PFDs,
P&IDs sub-lead for OSBL for new grassroots Nylon plant in Jubail, Saudi
Arabia. Interfaced with Environmental for design of wastewater treatment plant, as
well as tank farm and other off-sites. Lead Environmental for air pollution control,
including SCR, Electrostatic Precipitator, etc.
Senior Process Engineer, Invista (formerly DuPont) Boiler Upgrade Project, Victoria, TX.
Responsibilities included PFD, HMB and Material Selection Diagram for Phase II effort.
Also included is process studies and communication with vendors on pollution control,
including high temperature dust collector and SCR. Extensive studies were conducted on SCR catalysts for consideration of potential blinding, poisoning, and high temperatures. One fuel stream was waste solvent with significant metals. Detailed evaluation was conducted on effect of metals on catalyst. Mr. Parnell identified the problem, resulting in cancellation of project, which was later restarted with a different scheme. This was for a nylon 6,6 facility.
Senior Process Engineer, Heartland Upgrader Project, BA Energy, Calgary, Alberta, CA. Conducted extensive relief systems study on bitumen and diluent “solvent” systems. This involved detailed understanding of how this new process would operate with SAG-D generated extra heavy, sour crude.
Senior Process Engineer, OCC Operation Canadian Crude, BP North America, Whiting, Indiana. Project work included relief system studies for two hydrotreater sections, including all upstream and downstream equipment, Design of a refinery fuel glycol dehydration unit, including heat exchanger detailed ratings studies.
Senior Process Specialist, Polypropylene Expansion, Fotron Polymers, Wilmington, NC. P&ID development, heat exchanger design, relief system sizing, process studies. Identified inadequate relief sizing by others resulting in complete rework of reliefs and stamping of vessels. This involved parent company Celanese decision makers, Corpus Christi, TX.
Senior Process Lead, Methanol Recovery Project, Kodak, Rochester, NY. Led the
strategy for capturing methanol from various locations and unit operations, and recovering methanol by absorption, and adsorption. Accomplished targeted recovery, while meeting permit limits, and beating cost and schedule targets. Awarded “Shining Star” award, as a result of this effort and leading a team hand-picked by Mr. Parnell. Each team member received an award.

Senior Process Lead (on contract to Jacobs Engineering), Fiber Optics Expansion, Lucent Technologies, Norcross, GA. Various projects support for wastewater, caustic scrubbing, and a chemical purification Building. One event, individual cost savings of $23 million in TIC and production due to self directed study of a project. Study proved that the project was not required. Project was cancelled, and savings applied to other projects. This effort had to be sold and proven to the client. This was accomplished after Jacobs Engineering had left the site and an independent re-evaluation was conducted by Mr. Parnell with another contract firm. This was a caustic scrubber project removing hydrochloric acid gas. He was sked to stay-on for installation and start-up through special individual contract with Fluor Construction.

Developed P&ID’s for Coal Gas Phase II for production of Syngas that yielded Methanol and Acetic Anhydride that became “backbone” of thousands of downstream products. Studied reactive distillation for esterification methyl acetate, ethyl acetate, propyl acetate and butyl acetate. This reactive distillation was pioneered by Eastman Kodak (TN Eastman Chemical). Conducted large project work, studies, small capital projects, Process Lead, detailed equipment and system design, and long-term studies.
Given the only Eastman President’s Award ever given to a contract engineer by Eastman President Bill Garwood. As small capital Process Lead for the Organic and Acid Divisions of the plant, project duration averaged 28 days from receipt of project approval to CADD P&IDs, permit revisions, relief systems analysis, and any re-sizing of relief systems. Work included liaison between Engineering, Operations, Division Engineers and Chemists (for batch) to troubleshoot problems, make improvements, expand production and repair/replace equipment.
