Excessive carbon dioxide levels in the alkali scrubber tower

In the coal chemical MTO process, the carbon dioxide content in the reaction gas entering the alkali scrubber is determined by the reaction itself. If the reaction efficiency is poor, it is common for carbon dioxide levels to reach several thousand PPm. When the reaction becomes uncontrollable, it is necessary to control the operation of the alkali scrubber tower.
To what extent does a high carbon dioxide content in the methanol content affect the reverse reaction?
The regenerator’s regenerated catalyst stripping gas (usually nitrogen) can be increased appropriately
