The Design Load Calculation and Influence Factor Discussion for Vacuum System in Chemical Plant
This article introduces the basic concepts of gas load,air leakage rate,initial pumping speed,evacuation time,etc.in the vacuum system of chemical plant.It summarizes the main steps of determining the design load of the vacuum system,estimates the air leakage rate,calculates the process vapor flow rate and content,and calculates the initial pumping rate.Through practical calculations,it is summarized that reducing the air leakage rate in the vacuum system and lowering the inlet temperature of the vacuum system are the main methods to reduce the design load of the vacuum system.This provides ideas and methods for determining the design load of conventional vacuum systems in chemical plants.
