Amine Package on HYSYS
Amine Package on HYSYS
(OP)
i am working on the removal of carbon dioxide using the amine package on HYSYS v2.4.1 build 3870. I have managed to simulate it but the recovered carbon dioxide stream in the tops of the distillation tower (for stripping) has a temperature of -87.07degrees C. I was wondering if i might have made a simple error or if this is what i am supposed to get.
also i would like to incorporate this part of the simulation into the complete flow plan of my design which is in wilson package. Is this possible? any help would be much appreciated.
Thank you very much in advance
Best Regards

RE: Amine Package on HYSYS
what design specifications did you give for your simulation (Reflux ratio, boilup ratio, purity etc). it depends on what kind of design specifications you give. if you list them then i can get better idea of your problem.

RE: Amine Package on HYSYS
In HYSYS versions below 3.0, you can only change property package per subflowsheet, so you have to put the absorber (+ regenerator, if you insist on modeling that) inside a seperate subflowsheet.

RE: Amine Package on HYSYS
For an obsorber, simulate without a reboiler/condenser (typical). For a new tower, assume 20 actual trays. CO2 specification is acheived based on tower efficiency (# of trays), circulation rate (lean amine to absorber), lean amine wight % in the circulated stream, lean amine loading (CO2 and H2S load in lean amine) and sour gas feed.
Amine Absorber and Regenrator interact interdependently. CO2 to H2S (if any) ratio has an impact on lean amine loading. Other factors that impact lean amine loading is the regenerator reboiler/condensor and efficiecy of the regenerators (# of trays).
