Organic sulfur emissions from low-temperature methanol washing
Thread Content
May I ask, for low-temperature methanol washing, through which route does organic sulfur get emitted – via the acidic gas stream or from the reflux tank? Organic sulfur emissions are really a problem
There’s so much gas in it; otherwise it would all flow back, so how can it be discharged?
A large amount of acidic gas is released, mainly through the gas phase during the thermal regeneration process. Sulfur-containing compounds can be recovered by adding new sulfur recovery units
Acidic gases are generally subjected to sulfur recovery treatment, while organic sulfur is usually removed in the sulfur recovery unit
