Cyclic hydrogen desulfurization
Thread Content
Cyclic hydrogen temperature 47. Poor amine solution: 44 degrees. Can it achieve desulfurization?
Generally, the temperature of the lean liquid should be higher than that of the circulating hydrogen, but desulfurization is still possible.
We operate smoothly. But the sulfur content in the product has become excessively high!
Is a temperature difference of 6/7 degrees between the lean amine liquid and the recycled gas appropriate? Or not?
It is advisable to do so, but it’s not explicitly prohibited; it’s just that the desulfurization effect isn’t very good. Increase the amount of lean liquid used, and to determine whether the desulfurization effect is achieved or not, you can conduct tests and analyses rather than relying on theory.
Take a look at the hydrogen sulfide content in your recycled hydrogen; generally, when it is below 1000, the impact of recycled hydrogen is minimal.
The temperature of the recycled hydrogen is a bit high, but absorption should still be possible. The question is whether the light hydrocarbons will cool down and form a floating layer in the tower. foaming
This temperature can achieve desulfurization!
