rectisol process description


PROSIMPLUS APPLICATION EXAMPLE

Process description. In the Rectisol process (licensed by both Linde AG and Lurgi AG), cold methanol at approximately –40 °F (–40 °C) dissolves (absorbs) the acid gases from the feed gas at relatively high pressure, usually 400 to 1000 psia (2.76 to 6.89 MPa).The rich solvent containing the acid gases is then let down in pressure to release and recover the acid gases.
