Calculation and application of pressure balance in hydrogenation unit reaction system
At present,there is no clear method or reliable theoretical basis to determine the design pressure of each high-pressure equipment in the hydrogenation unit reaction system.This article is based on the pressure balance calculation theory of a typical hydrogenation reaction system described in Appendix B of API521-2014,and calculates and determines the design pressure of each equipment one by one according to their actual pressure drop.The calculation sheet prepared has the characteristics of strong theoretical basis and convenient application,providing reference and guidance for relevant designers to determine the design pressure of high-pressure system equipment in hydrogenation units.
