Hydrocracking and Hydrotreating Process Technology Course


This training course is to provide an in-depth, yet practical review of both hydrotreating and hydrocracking technologies for the refining of petroleum. The course will cover topics ranging from the chemistry of hydrotreating and hydrocracking to a discussion of the design of commercial processes and reactors. The program will also address fcc feed pretreatment, diesel and jet fuel production, naphtha hydrotreating, and hydrogen production and purification.
