Amine Scrubbing for CO2 Capture
Amine scrubbing has been used to separate carbon dioxide (CO2) from natural gas and hydrogen since 1930. It is a robust technology and is ready to be tested and used on a larger scale for CO2 captureExpand

Aqueous piperazine as the new standard for CO2 capture technology
Abstract Amine scrubbing will be the technology of choice for CO2 capture from coal-fired power plants. 7 m monoethanolamine (30 wt% MEA) has been the standard solvent to represent the capability ofExpand

Modeling of CO2 capture by aqueous monoethanolamine
The process for CO2 removal from flue gases was modeled with RateFrac. It consists of an absorber, a stripper, and a cross heat exchanger. The solvent used in the model contains about 30 wt %Expand
