Refining Process Services, Inc. provides technical training seminars in the field of petroleum refining, also called oil refining. The modern petroleum refinery has a series of core process units that create clean gasoline and low sulfur diesel fuel. The first oil refinery unit is crude oil desalting. The desalter removes salt, water and other contaminants from crude oil prior to distillation in an atmospheric tower. The fractions recovered from the atmospheric distillation tower include naphtha, kerosene, diesel and bottoms liquid called atmospheric resid. This material is fractionated via vacuum distillation into gas oil and vacuum resid.


Raw gasoline recovered from petroleum consists of light naphtha and heavy naphtha. Light naphtha is processed through an isomerization unit and heavy naphtha is processed in a catalytic reforming unit or reformer so that gasoline octane is improved. Kerosene is blended into jet fuel. Diesel fuel is treated in a hydrotreating unit or hydrotreater with catalyst and hydrogen to reduce sulfur level and improve quality. Gas oil is converted in fluid catalytic cracking and hydrocracking units or hydrocracker into gasoline and diesel. Light olefins from the fluid catalytic cracker are processed in either HF acid (hydrofluoric acid) or sulfuric acid alkylation units. Vacuum resid is processed in delayed coking units which convert heavy oil from crude into lighter products.


To learn more about this vital industry, Refining Process Services offers a series of technical training seminars. All programs are offered in the form of public seminars.   Most programs are also offered for in-house presentation at a client location.  Select theOn-Site Training tab for  more information.  A listing of core seminars is provided below.

Crude distillation is the first process in the refining sequence and is vital to the profitability of refinery operations. This importance has grown with the advent of cleaner fuels.  This program has been developed to provide an in-depth yet practical review of the art and science of crude distillation.  Consistently maintaining smooth operation, capacity and product quality are critically important goals that can be difficult to achieve.  Many complex process, equipment, and reliability issues have to be balanced to optimize run-length, capacity, and quality.  With the many variables involved, constant adjustments are required.

The program’s content is both comprehensive and wide-ranging.  Sessions begin with a discussion of fundamentals, including process objectives, crude oil characterization, products, process flow sequences, heat integration, desalting, and major equipment design.  Attendees will gain an understanding of how process requirements, equipment operation, and economic objectives interact.  Once the fundamentals are established, the session moves into the topics of operation, control, troubleshooting, and revamps.  The program speaker is Mr. Andrew Sloley, a  Principal Engineer at CH2M Hill in Bellingham, Washington.

Program participants will have ample opportunity to obtain a broad working knowledge of crude unit operations, to gain insight into current technology and trends, and to interact with others working in this area.  The program is ideal for personnel involved in refinery process engineering, plant operations, troubleshooting, and technical services.  Process engineers from design and construction companies as well as those providing services to the petroleum refining industry should also find this program beneficial.
