What is the reason for the high COS content in the process gas?
This is related to the high concentration of carbon dioxide in acidic gases.
It is caused by an improper selection of the reactor burner or side reactions resulting from an excessive amount of acidic hydrocarbons.
The catalyst in the Klaus reactor has poor hydrolysis efficiency.
It is related to the CO2 concentration in the process gas.
COS is primarily produced in reaction reactors； Possible reasons for high COS levels in exhaust gas: 1. Low temperature in the primary converter ； 2. No hydrolysis catalyst or catalyst deactivation. 3. The temperature control in the hydrogenation reactor is too low, or the catalyst is deactivated. 4. The hydrocarbon content in the raw material is too high, but the furnace temperature is not high.
Answer: The high COS content in the process gas is caused by the high hydrocarbon content in the acidic gas
COS is primarily generated by the reaction of H2S with CO2. The high concentration of COS in the process gas is related to the CO2 concentration in the feed gas, as well as to the activity of the hydrolysis catalyst in the reactor
