摘要： The invention is directed to processes and apparatuses for gas treatment, in particular for the purification of methane rich gas streams, such as gas obtained from the conversion from organic matter ("biogas"). In accordance with the present invention there is provided an apparatus and a process for producing a purified methane comprising gas stream (P) from a methane containing gas stream (A), comprising the steps of: (a) pressurising said methane containing gas stream (A) and subsequently cooling it, whereby a stream comprising condensed contaminants (C) and a methane comprising stream (B) are obtained; (b) optionally feeding said methane comprising stream (B) to an adsorption unit and/or a catalytic conversion unit, whereby the concentration of contaminants in stream (B) is further decreased; and (c) cooling the methane comprising stream (B) to a temperature which is sufficient to condensate CO 2 from said stream (B), whereby said purified methane comprising gas stream (P) is obtained.

(a) providing a nitrogen-containing stream (10) having a pressure of at least 5.0 bara and a temperature of at most 20°C;
(b) cooling the nitrogen-containing stream (10) in a first (2) and a second heat exchanger (3) thereby obtaining a cooled nitrogen-containing stream (30);
(c) expanding the cooled nitrogen-containing stream (30) thereby obtaining an expanded nitrogen-containing stream (40);
(d) separating the expanded nitrogen-containing stream (40) in a gas/liquid separator (4) thereby obtaining a gaseous nitrogen-enriched stream (50) and a liquid nitrogen-depleted stream (60); and
(e) heating the gaseous nitrogen-enriched stream (50) in the first or second heat exchanger (2,3) thereby obtaining a heated nitrogen-enriched stream (70).
