Dry gas hydrogen sulfide removal process
Thread Content
For the removal of hydrogen sulfide from dry gas, do refineries generally use DEA absorbents or MEDA absorbents? What is the mass fraction of these absorbents?
Dry gas is desulfurized of hydrogen sulfide; generally, refineries use MEDA absorbent, with a mass fraction of 30-40%.
Thank you. What type of trays are generally used in such absorption towers?
Float valves are probably used more often.
The trays we use are also floating valve type, and we employ MEDA absorbent at a concentration of 30, with a temperature of 30–30°C; the results are very good
