The H2S levels in the rich and lean fluids vary depending on the different units used. For hydrogenation units, a H2S level in the lean liquid of ≮2 g/l is generally sufficient, while the H2S level in the rich liquid is usually around 20–30 g/l. As for the lean liquid required for the exhaust gases from sulfur recovery units, a level of ≮1 g/l is typical, with the H2S level in the rich liquid being around 4–10 g/l.
In our unit, the hydrogen sulfide content in the lean liquid is not more than 0.1 mg/l, and the carbon dioxide content is not more than 1 mg/l
Are the indicators mentioned upstairs true? That’s world-class level!
4# adsl121 What are your metrics? What is it used for?
The hydrogen sulfide content in the lean liquid should not exceed 0.1 mg/l; the performance of various technologies in this regard is quite high. Our standard for precise desulfurization is 0.03 PPM
The lean liquid required for the exhaust gas from our sulfur recovery unit is usually ≮1g/l, while the H2S concentration in the rich liquid is generally between 4-10g/l.
Generally, the requirement for lean liquid in sulfur plants is no more than 1 G/L
Generally, the indicators for sulfur recovery are this low; otherwise, it will cause foaming in the amine solution.
