<p>In removing gaseous impurities from a gas mixture under pressure with an absorption liquid which is regenerated in a low pressure zone an improvement comprises taking used absorption liquid from the pressurized absorption zone, expanding it in an ejector whereby a sub-atmospheric pressure is created, freeing contained gaseous impurities. Separation of gaseous impurities and liquid occurs, and separated liquid is subjected to the subatmospheric pressure of the ejector whereby further gaseous impurities are evolved, and returned to the absorption zone.</p> |
