Suction load of vacuum system

The suction flow rate or load to a vacuum system consists of non-condensable gases and condensable process vapour. Non-condensable gases may come from  

Suction and They are suitable for almost any Suction pressure must be greater than Power consumption and 

Suction fiow rate They can be designed for almost any suction flow rate Limited to 22 000 acfm (Ryans and Bays, 2001) Limited to 1400 acfm 

Gas moiecuiar weight and temperature The higher the gas molecular weight is, the lower are the capital and operating costs, more capital and operating costs Higher gas temperatures require 

Main utiiities They require steam at 0.5 barg pressure Electricity for LRVP and closed-loop seal liquid pump Electricity for blower/compressor
