Simulation of low temperature methanol washing process
Thread Content
Using Aspen to simulate the low-temperature methanol process, it always fails to converge. The temperature and outlet CO2 content are wrong. What is the problem? Help!!!
You must first consider whether the characteristic parameters are selected correctly.
I've encountered this before, haha. This post was last edited by liuyiyong85 on 2009-3-17 16:58 ]
The absorption tower is indeed a bit difficult to converge. It is recommended to define the initial values yourself, such as temperature distribution, flow distribution, etc. It is recommended to use PSRK for physical properties
The calculation method uses wide-boiling, do not use standard
If you do not correct the physical properties of methanol at low temperatures, the converged results will not be credible.
I am a newbie, where can I modify the physical properties of methanol?
Very nice, let’s chat when we have time :)
