Methyldiethanolamine - an overview | ScienceDirect Topics
Methyldiethanolamine (MDEA) is a tertiary amine and commonly used for removal of acid gases from gas streams. MDEA does not react with COS and CS 2 , which avoids loss of solution. COS can be physically removed by MDEA only with very high solvent circulation rates, at which point the CO 2 is also removed quantitatively ( Korens et al., 2002 ).
