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.
