Working principle of desulfurization tank
Thread Content
I have just started learning the *methanation process*. Does the desulfurization tank absorb H2S and COS? Does it need to be regenerated? The reaction equations governing the operation of the desulfurization tank are: H2S + ZnO = ZnS + H2O; COS + H2O = CO2 + H2S. So, what happens to ZnS in the end? Thank you
Zinc oxide desulfurization cannot be regenerated; it should be shipped as hazardous waste.
Precise desulfurization mainly removes hydrogen sulfide; the desulfurizing agent cannot be regenerated and is for single-use only.
According to the master, the desulfurization tank consists of two adsorption tanks; once one tank becomes saturated with adsorbent, the other one is used, and then the adsorbent in that tank is replaced
