HYSYS simulation of the amine liquor load at the outlet of the natural gas purification absorption tower
Thread Content
When using MDEA to purify natural gas in simulations, the issue of “Amine CO2 molar loading (CO2 mols / amine mols) out of amines package range” occurs at the top outlet of the absorption tower. This is because there is almost no MDEA left at the tower’s top, but there is still some CO2 present. I saw in the documents that the allowable range for the acid gas load is between 0 and 1, but it seems to me that there isn’t any problem from a calculation perspective... What should be done? I seek advice
The hint indicates that it has been used beyond its limits.
But there’s no MDEA coming out of the top of the absorption tower... Is that wrong?
"I see in the document that the limitation for the amine package is that the acid gas load must be between 0 and 1; this applies to the amine solution. No need to consider the gas at the top of the tower; ignore this hint.
But that line is yellow... It probably won’t work behind it
