Carbon dioxide absorption in piperazine activated N-methyldiethanolamine

The removal of carbon dioxide from process gas streams is an important step in many industrial processes for a number of technical, economical or environmental reasons. The conventional technology to capture CO2 on large scale is the absorption - desorption process, in which (aqueous) solutions of alkanolamines are frequently used as solvents [Kohl and Nielsen, 1997]. Nowadays, the addition of an activator, or more specifically piperazine (PZ) to an aqueous N-methyldiethanolamine (MDEA) solution has found widespread application in the bulk removal of carbon dioxide. The principle of such a blend of a primary or secondary (alkanol)amine and a tertiary alkanolamine is based on the relatively high rate of reaction of CO2 with the primary or secondary alkanolamine combined with the low heat of reaction of CO2 with the tertiary alkanolamine, which leads to higher rates of absorption in the absorber column and lower heats of regeneration in the stripper section
