What is the required purity of CO2 in the inlet gas to the caustic carbonation tower?

It should work; with even air intake, the reaction should be more uniform as well
Carbon dioxide technical specifications: Parameter, Unit, Quantity. CO2 % (mol): ≥98.5; H2S+COS % (mol): ≤5ppm; CH4 % (mol): ≤250ppm. Temperature, °C: ≤30. This carbon dioxide gas is used during the alkali production process in the lower section. Depending on the production conditions, the concentration of some intermediate gases can be reduced slightly; the gas from the calcination furnace, with a concentration of over 60%, can be used as a cleaning gas.
Insufficient purity affects the reaction efficiency.

Purity seems to be concentration; concentration is a more appropriate term.
