Simulation of CO2-H2S acidic gas absorption using MEA-MDEA solution
Thread Content
I’m following up on this – regarding the simulation of CO2-H2S acidic gas absorption using MEA-MDEA solutions, have any colleagues provided an example of convergence? Thank you.
In my simulation, I require gasout, with an H2S concentration of less than or equal to 1.5*10^-5. I established a design specification, but errors keep occurring
Aspen comes with a data package. Without accurate physical property parameters, accurate simulation is impossible, especially at concentration levels in the ppm range. The issue of non-convergence is mainly addressed by introducing tearing flows and using estimated values
1. In the convergence options for the distillation column, change the absorption model to No. 2. 2. Set the error value in the convergence options of the distillation column to at least less than e-5; this will enable convergence
There’s a data packet attached------where can I find it?
:Victory: It’s stronger, how to explain it? ! I am the absorption tower Ah
