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.

CRUDE OIL DESALTING

The desalting of crude oil is a process that does not have a high profile, but is vital to the operation of the modern petroleum refinery.  Desalters provide more protection to costly refinery equipment than any other single piece of process hardware.  Refining Process Services and Nalco Champion have developed this program to provide an in-depth, yet practical review of both the art and science of crude oil desalting.  Maintaining smooth operation of crude oil desalting units is both critically important and quite difficult.  Since there are so many significant variables to control, desalter operation must constantly be adjusted to maintain optimum performance with the ever-changing sources of crude oil.

The program's content is both comprehensive and wide-ranging.  Sessions begin with a discussion of the fundamentals of the desalting process including crude oil quality impact, the operating variables, key equipment, various design options and major process variables.  Once the fundamentals are established, discussion moves into the topics of unit operations, monitoring, and process troubleshooting.  An experienced group of industry professionals has been assembled for the presentation of this program.  The speakers are Mr. Dennis Haynes and Mr. Edgar Villoria of Nalco Champion, and Mr. Tom Collins and Dr. Isis Mejias of Forum Energy Technologies.

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