Gas at the top of the acidic water tank in the acidic water production unit
Thread Content
The gas at the top of the acidic water tank in the acidic water production unit contains large amounts of hydrogen sulfide; please advise on how this gas is recovered
It passes through an advanced water seal tank, then enters the spray tower where it is absorbed by a lean amine solution; afterward, it is pumped using a vacuum pump into the low-pressure flare line
Pressurize the intake tank or the inlet to the catalytic compressor using a water ring pump
Using the compressor inlet for this purpose is questionable.....
What factors could have an impact?
It is more reasonable for it to enter the sulfur recovery unit together with acidic gases as feed gas! After all, large amounts of hydrogen sulfide gas are not good for the equipment in the plant; even if the equipment can handle it, the catalytic dry gas still needs to be desulfurized. The gas after desulfurization must then be sent to the acid gas pipeline network for sulfur recovery. Isn’t this just taking a roundabout route?
Currently, at the top of the raw water tank, two tanks are generally installed: one as a water seal tank and the other as an adsorption tank. After the gas phase emerges, it passes through an exhaust gas booster pump before entering the exhaust gas absorption tower (where it is absorbed by amine solution), and finally the exhaust gas is sent to an incinerator. . . . .
