Molecular Sieve Adsorber (MSA) is where the separation process between carbon dioxide and water vapor is still contained in the air. If the process in the MSA does not take place perfectly, the value of CO2 content can increase. The output gas from the MSA will then be sent to the coldbox. If the value of CO2 content entering the coldbox is more than 3 ppm, crystallization can occur in the cold…
