Title:
METHOD AND APPARATUS FOR HYDROCRACKING
Document Type and Number:
Japanese Patent JP2002088376
Kind Code:
A
Abstract:
To provide both a method for hydrocracking by which the energy efficiency is high and the structure is simplified and a system for accomplishing the method.
This system for hydrocracking is equipped with a hydrofining reactor 14 for hydrofining a raw material for hydrofining in the presence of hydrogen, a fractionator 18 for fractionating a hydrofined oil into a light fraction and a heavy fraction and a hydrocracking reactor 24 for hydrocracking the fractionated heavy fraction in the presence of hydrogen. The oil hydrocracked in the hydrocracking reactor 24 is fed back through a passage 40 to the fractionator 18. A fractionating column is used in common for the hydrocracking reactor 24 and the hydrofining reactor 14.
