Abstract:

The feasibility of producing 5# industrial white oil in a VGO hydrocracking unit was analyzed. The process was simulated by Aspen Plus. The viscosity and flash point of diesel product could be optimized by adjusting the operating parameters of the fractionation system without modifying the reaction section, and the product properties could meet the standard of 5# industrial white oil (I). It further improved the economic benefit of the unit, widened the range of product and improved the comprehensive competitiveness of the refinery.

Key words: hydrocracking;white oil, viscosity, flash point
