In order to boost production of a product (A) of an existing separation plant (X, ), an additional plant (Y) is integrated with the original plant so as to enable the original plant (X) to produce more of that product (A&plus;B), whilst the additional plant may or may not necessarily itself produce the same product directly. For example, air is separated in a first unit, which is an existing double column distillation plant, to produce an oxygen rich fluid. So as to increase the production of the oxygen rich fluid, a second unit, which is a wash column ( ), is integrated with the first unit. Air ( ) is separated in the single nitrogen wash column ( ) to remove oxygen and gaseous nirogen ( ) is produced at the top of the column. The wash column is fed with liquid nitrogen ( ) from the high pressure column ( ) of an existing air separation unit.

Variable capacity fluid mixture separation apparatus and process

A gas treatment unit is operated or placed in over-capacity mode during periods of low or zero electrical consumption by a metal treatment unit in order to produce a gas, at least a major part of which is not sent to the metal treatment unit during those periods but is at least temporarily stored in liquid or gas form.
