TECHNICAL SEMINARS

istock 000000784409small

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.

DELAYED COKING PROCESS TECHNOLOGY

In order to increase the value of refinery products derived from the bottom of the crude oil barrel, many refiners are introducing delayed coking into their processing configuration. This program has been developed by Refining Process Services to provide an in-depth discussion of the process fundamentals and mechanical systems associated with the operation of a delayed coking unit. The information presented ranges from a description of heavy oil chemistry through a discussion of the current trends driving delayed coker revamps and re-configuration of refinery heavy oil processing schemes.

The program will be presented by Mr. Jerome DeHey of I Cubed Energy Consulting. The presentation has been designed for those professionals who are interested in the operation , process engineering, technical support or design of a delayed coking unit. This information will also be very useful to those responsible for refining coordination and research & development, and to those who supply products and services to the petroleum refining industry.
