Method&Equations

The strong liquor and vapor stream pressures are set to the specified pressure. The outlet Condensate and Vapor are assumed saturated at the given pressures.
Vapor = Steam*Economy
LiquorOut = LiquorIn –Vapor
Condensate = Steam
Temperatures are set for the Liquor as given for Condensate and Vapor the saturation temperatures.
