Amine Unit Acid gas loading calculation

Amine Unit Acid gas loading calculation

Amine Unit Acid gas loading calculation

I'm trying to calculate the acid gas loading on our amine unit as per API 581, where it states , 'acid gas loading is reported in terms of moles of acid gas per mole of active amine.' it says both H2S and CO2 must be measured to determine the acid gas loading, in addition only the amount of available or "active" amine should be considered when calculating the loading'. So with this in mind if I have a 25 wt% DEA amine and a H2S concentration of 40000ppm. would you work out the acid gas loading for the total liquid encluding the H20 or would you work it out just for the 25% DEA?  

RE: Amine Unit Acid gas loading calculation

what about the term mole per mole confuses you? how many moles of H2S / CO2 are being removed per mole of amine are you seeing or calculating.

RE: Amine Unit Acid gas loading calculation

My  college, you can use this formula:

rich amine loading=( sour gas rate Nm3/hr * H2S concentration Mole% * 119.7)/(amine rate m3/hr * amine strength * 22.414 * 1000)

note that: 119.7 is diethanole amine molecular weight, if you uses other amine type use it's molecular weight.

the result will be in mole H2S/mole amine
