Overview of Hydrocracking Unit

Hydrocracking Units, also known as Hydrocrackers, are types of process equipment used in petroleum refining. Hydrocrackers use hydrogen and a catalyst to break down heavy crude oil molecules into various distillates and gasoline. It is also useful for converting high-sulfur materials into low-sulfur fuels, making them more useful.

The cracking process begins when heavy oils are sent from the fluidized catalytic cracking unit (FCCU), the coker unit, and atmospheric or vacuum distillation tower to the hydrocracker. There are two main chemical reactions that occur once the oil gets there. The first is distilling heavy hydrocarbons into lighter unsaturated hydrocarbons. The second reaction involves saturating these lighter hydrocarbons with hydrogen.
