Desouring Water using Aspen Plus (Electrolyte System)

A sour water stream, which contains 0.20 wt% CO2, 0.15 wt% H2S, and 0.1 wt% NH3 at a temperature of 85 degC and pressure of 1 atm with a mass flow rate of 5000 kg/h, is to be treated by a dry steam at 1.1 atm and a mass flow rate of 1500 kg/h. The water polluting compounds will be stripped off the sour water and vented, with some amount of water vapor, off the top of the stripping tower. The sweet water will be withdrawn from the bottom of
the stripper with almost nil carbon, nitrogen, and sulfur content. The dry stream, entering from the bottom, will act as the vapor stream within the column; hence, there is no need for a reboiler. On the other end, the rising vapor stream will be substantially condensed and recycled to the top of the column as a liquid reflux, whereas the rest of it will be vented offthe top of the tower.
