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.

The Refinery Distillation: Operation & Troubleshooting course covers fundamentals and practical application of distillation in refining processes. The material covers the fundamentals of distillation processing, process considerations, equipment considerations, control and troubleshooting. Extended material covers a variety of advanced topics. Every major distillation application in the refinery is discussed. Proper operation of these units is critical to meeting product specifications and achieving optimum profitability. Multiple case studies are used to illustrate the relative importance of different points.

Extensive coverage includes both process and equipment considerations in revamping existing units, as well as both conventional equipment and modern high-capacity equipment used to expand capacity of existing units. The revamp discussion covers practical considerations involved in tower revamps including equipment selection, impact of modifications on turnaround duration, balancing technical risk against stretch objectives and other practical needs that must be included for successful revamps. Extensive discussion covers many of the factors for assuring a successful revamp instead of a failed expansion project. Recent process intensification steps such as alternate process schemes including refinery applications of divided wall towers will be presented.


The program’s content is both comprehensive and wide-ranging. Time is allocated each day to invite participation from participants for presentation to the audience. 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 Consultant at Advisian (WorleyParsons Group) in Bellingham, Washington.
