Adding and removing absorbents
Thread Content
The specific gravity of the crude oil increased from 0.90 to 0.94; the reaction temperature was not adjusted, nor was the feed rate altered, resulting in a significant increase in C2 in the liquefied gas. The temperature in the desorption tower should be increased accordingly, while the pressure in the absorption tower should be reduced. Should the concentration of the absorbent also be decreased? In the past, the crude oil was quite heavy, resulting in a large amount of dry gas being produced and little light oil. I believe that although the gas phase load is high, there is no liquefied gas available for absorption, so adding more absorbent wouldn’t bring any benefit. Please have an expert analyze it.

I think for deciding whether to increase or decrease this amount, it’s necessary to examine the components of the dry gas to understand its composition before making a decision; one can’t rely solely on personal experience
The amount of absorbent to be used should be adjusted based on the results of the dry gas analysis, with the dosage being modified according to those results
