Hydrogen sulfide content in the lean liquid
Thread Content
What level do you guys keep for the hydrogen sulfide content in the lean solution? Here it’s 2 g/l; I’m not sure what level others use. How can this value be adjusted if it’s too high?
For dry gas and liquefied gas desulfurization, this parameter is fine.
For the indicator of solvent regeneration alone, it’s a bit high. It is best to keep it below 1, to enhance regeneration and filtration, and to remove an appropriate amount of water from it through analysis.
Yours is a bit high; ours don’t have that, and when it appears, it’s around 0.04. (Solvent regeneration of sulfur)
Here, I have separate solvent regeneration for use with my own catalytic units
0.04 is so low; it should be 0.4. As long as the value is less than 1, absorption is possible, but when it’s greater than 1, the absorption effect deteriorates.
What amine solution are you using? Domestic or imported?
We are using the domestically produced JCS-93B high-efficiency desulfurizer
