| Subject: Amine column operation |
| |
| Question: |
|
Has anyone faced the problem of high H2S in the fuel gas outlet from amine tower? It is observed that the H2S absorption was affected by CO2 absorption. Simulation of the column is done. It was observed that actual CO2 in the fuel gas outlet is less that the simulation output. This represents the absorption kinetics towards CO2 than H2S. Is there any trick to control the absorption kinetics towards H2S/CO2?

Each amine has a different selectivity between absorbing H2S and CO2. You may not have the appropriate amine for your situation. The most common amine for this service in refineries was DEA, and now is MDEA.

Please look at the amine type. MEA is strongly selective for the absorption of CO2 followed by DEA. Consider the amine to MDEA.

I think you can improve the selectivity by reducing the temperature in the tower. Is this an option?
