removing mercaptans from tail gas
removing mercaptans from tail gas
(OP)
hi!
i am just starting a new project on removing of mercaptans (3000 ppmv) from gas. i am unaware of the processes that can help to remove the mercaptans. can someone help me?

RE: removing mercaptans from tail gas
Does your gas stream has H2S in it, if yes what is the mole % or ppmv present? Do you want all of your mercaptans removed?

RE: removing mercaptans from tail gas
Reducing a mercaptan stream from 3000 to 3 or 4 ppmv is a tall order, especially since H2S makes up less than 50 ppmv out of the 3000. For this kind of efficiency, your best bet may be oxidation (say with RTO), followed by a wet scrubber to take out the resulting SO2 with a base.
