Heavier feedstocks are generally difficult to process by catalytic cracking or reforming, but can be converted by hydrocracking. The feedstock is cracked by catalytic cracking in the presence of hydrogen, and hydrocracking produces a mixed stream of gasoline and distillates. About a dozen different hydrocracking process schemes are currently in use.

challenge:

Catalyst stripper, separator liquid and flash tank liquid level control must be adapted to harsh process conditions to maintain optimal operation of the hydrocracker. These conditions include elevated temperature and pressure, the presence of steam and high-pressure hydrogen, and corrosive liquids.
