Lean/rich exchanger: Sensible heat from the lean amine is used to heat incoming rich amine to maximize heat recovery.


In the MEA [mono-ethanol amine] process ... the gases go to the absorption column where the carbon dioxide binds to the solvent chemically. Most of the CO2 is thus removed from the exhaust gas that is released to the atmosphere and the reach solution (i.e. the solution containing the absorbed CO2) flows to a lean/rich heat exchanger: here the hot lean solution, coming from the stripper column (regenerator), cools itself giving out its heat to the rich solution, which then goes to the regenerator.
