Background
Many refinery operations produce what is called sour water.Any
refinery process water that contains sulfides isconsidered to be
sour water.

wastewater system.

Problem Statement
Use Aspen HYSYS to simulate the process of removing ammonia
and
hydrogen sulfide from a waste water stream.
-Assume a waste water stream containing mass fractions of
0.988water, 0.005 ammonia, and 0.007 hydrogen sulfide.
-This waste water stream is at a temperature of 37.78C, a
pressure of2.758 bar, and has a mass flow of 328,900 kg/h.
-The goal is to produce a stream with a maximum of 0.00005
mol%
ammonia while recovering 99% of the water in the waste water
feedstream.
