- Learn to simulate sour-water stripping in Aspen HYSYS. The sour-water produced from a crude tower is heated and then purified in the stripper to obtain off-gas and pure water streams. Damping factor plays a vital role in the convergence of the simulation. Please do watch, like, and share the video, and subscribe the channel.
Problem Statement:
A sour water stream consists of 98.8 wt. % water, 0.5 wt. % ammonia, and 0.7 wt.% H2S is produced from a crude tower. The stream is at 37.78 °C, 2.758 bar, and at a flowrate of 1000 kg/h. The stream is heated to 100 °C, 2.069 bar and then fed to the stripper. The requirement is to produce a pure water stream with a maximum of 0.00005 mole% ammonia, while recovering 99% water. The stripper has 8 stages, with feed entering at 3rd stage. The condenser pressure is 1.979 bar, and reboiler pressure is 2.255 bar.

Gr8....i hv simulated using ur ideas. Thanks Dr.
Good to hear that
Can you provide the calculation
sir in case which the stages that we don't know, how you determine the stages of the absorber/stripper in HYSYS? since we know if the distilation we can use shortcut column but not with absorber/stripper
Most of the times, while adding comp fraction in monitor tab. My Wt. Error diiferes from yours although i followed the same steps as your and same values. Why this happen? Does it have concequences on the calculations?
Very good presentation
Thanks a lot
Sir ❤❤❤
Thanks Mohsin.
Thank you very much sir
Can you tell when to select stream/stage when adding a spec in distillation column?
It will depend on the specification. If any particular value is required from a particular stage, then this spec will be used. However, mostly the specifications presented in the video are used.
In refinery there is use only one stripper but in coke oven industry there is use double stripper coloumn sir...pls send ur email id sir...and thanks for ur nice video...
Yes, I agree. I will send shortly. As I want to have correspondence on different email address :-)
