Feed rate of the exhaust gas absorption tower

This post was last edited by liaifeng on 2018-9-1 at 12:18. What is the appropriate feed rate for the exhaust gas absorption tower? Is there a proportional relationship between it and the amount of exhaust gas to be purified?
By analyzing the rich liquid sample at the outlet of the absorption tower, the hydrogen sulfide content is generally in the range of 3.2–3.5 g/l.
Does \"purified exhaust gas\" refer to the exhaust gas coming out of the hydrogenation reactor, or the exhaust gas coming out of the quench tower?
The exhaust gas exiting the quench tower contains over 10,000 parts per million of hydrogen sulfide, while the concentration in the exhaust gas after passing through the absorption tower is around 20 parts per million; both values are on the PPM scale. Therefore, I believe there won’t be much difference in the gas levels before and after treatment! There’s some water left, but it probably isn’t much!
