CO2 removal by Mdea method

What are the key points for CO2 removal using the MDEA method?

It has been observed that in the presence of both hydrogen sulfide and carbon dioxide, MDEA can absorb less carbon dioxide; in other words, to increase natural gas production, using MDEA to absorb less carbon dioxide can help boost natural gas output. But regardless of the issue with hydrogen sulfide, or in the absence of such an issue, using MDEA to absorb carbon dioxide is definitely no problem; it basically comes down to the relationship between the amine solution concentration, the absorption rate, and the number of trays.
Reduced carbon dioxide absorption by MDEA can increase natural gas production. Behind is where the LNG will freeze and get blocked.
