Low Temperature Methanol Cleaning Gas H2S Active Carbon Absorbent
Here's how it works:At present, the technique of removing H2S and
COS by low temperature methanol has been widely used. It must have
water vapor and oxygen when desulphurizing. But the gas washed with
cold methanol often contains trace amounts of hydrogen sulfide.
This part of the hydrogen sulfide entering the downstream section
can be very harmful to the system. For this part of hydrogen
sulfide gas we often use activated carbon desulfurizer to remove.
In theory, O2: H2S≥5. Water content close to saturated water is
best. But the gas must contain liquid water.
