Three-step condensation process was used to separate and condense NH3 in side-draw stream of pressurized stripper,which was used to pre-treat coal-gasification wastewater.A mathematic model for the condensation was established and the effects of operation temperature and pressure on NH3 flow rate and NH3 concentration were analyzed based on this model.The model was optimized for maximum yield NH3 flow rate.The simulation indicated NH3 flow rate would increase 5.6% after optimized.
