What is the reason for the high COS content in carbon dioxide from low-temperature methanol washing? In a certain enterprise, the increase in COS content in the carbon dioxide from low-temperature methanol washing has a significant impact on methanol synthesis.
Sulfur-tolerant shift catalysts also have the catalytic function of COS hydrodesorption. If the activity of the conversion catalyst decreases, it will inevitably lead to an increase in the COS content in the gas fed into the low-temperature methanol wash process.
