Cyclic hydrogen desulfurization
Thread Content
Cyclic hydrogen was simulated using MDEA desulfurization, with the H2S content in the rich liquid of the absorption tower at 82 g/L during the simulation. The hydrogen sulfide content in this rich liquid seems to be a bit high; the hydrogen sulfide content in the lean liquid is 0.8 g/L. I would like to ask, why is this?
It depends on factors such as the hydrogen sulfide content in the recycled hydrogen, the total amount of recycled hydrogen, and the quantity of amine solution. Once the actual data are available, can the above problems be resolved?
Next, regarding the second floor, you haven’t specified the hydrogen sulfide content in the recycled hydrogen, the total amount of recycled hydrogen, nor the amount of amine solution. Since it’s a simulation, what is then the processing capacity of your desulfurization tower? The entire simulation process likely requires a lot of data; it’s difficult to determine what’s going wrong just by mentioning these few points
