The proportions of H2S absorbed by the rich and lean liquids are different
Thread Content
In the regeneration section of my unit, analytical tests show that the H2S absorption level in the lean liquid is sometimes 2%, while it is 14% in the rich liquid. But sometimes, the concentration of H2S absorbed by the lean liquid is 2%, while that in the rich liquid is 5%. Could the low absorption rate by the rich liquid be related to the small amount of H2S present? If there is less H2S entering the rich liquid, could this result in a low absorption value as well, which in turn leads to low values in the analytical tests? Thank you; I’m not quite sure. Please explain, and I’ll give points for helpful answers
There are also factors such as improper control of process parameters, the use of catalysts, and other aspects that can have an impact
