Optimal Design Process of a Steam Jet Vacuum System for a Hydrocracking Unit

Resumo

The article describes the calculations and design of a steam jet vacuum system for the column of a hydrocracking unit. Based on calculation results (considering specific operating conditions of the production), several variants of pressure distribution through the pump stages were calculated, and the optimal schematic of the vacuum system was defined, yielding a 20% reduction in energy consumption and a 15% reduction in capital costs.
