How to deal with a catalytic dry gas hydrogen sulfide aging value greater than 20
Thread Content
The hydrogen sulfide level in the dry gas before desulfurization is 8,000, and the flow rate of the lean liquid in the circulation system is 30 T/S – why isn’t it still up to standard?
What’s the concentration? Is it too low?
It is possible to measure the hydrogen sulfide content in the lean liquid as well as its concentration; this will help determine whether the regeneration process is not working effectively. Additionally, if the conditions of the tower permit it, the amount of lean liquid can be increased

Analyze the hydrogen sulfide content in the lean liquid (a high content indicates issues such as leaks in the heat exchanger or poor regeneration). 3. Check whether the flow rate is accurate (whether there is a problem with the gauge). 4. The temperature control of the regeneration tower should be appropriate (120-125). It’s best not to use a fractionation medium!
It’s not that high before separation; try increasing the tower pressure and the residence time. Replace the desulfurizer to eliminate its influence.
It sometimes goes above 12,000 here.
Here we also have tens of thousands; there’s really no way out
