According to an embodiment of the invention, nitrogen gas of an air separation unit is used to cool the gas formed in a reservoir of liquid from an MEOH unit that is supplied with oxygen by said air separation unit.

Integrated method and unit for air separation by cryogenic distillation and gas cooling

Process for producing gaseous oxygen by cryogenic distillation of air, wherein a portion of the feed air flow is brought to a pressure P, by means of a first compressor, the suction temperature Tof which is between 0 and 50&#xb0; C., the gas at the pressure Pis cooled, in order to generate an air stream at the pressure Pand the temperature Tbetween 5 and 45&#xb0; C., a portion of the air compressed in the first compressor undergoes an additional compression step starting from the temperature Tand pressure Pto a pressure Pgreater than P, then is cooled, to the temperature Twhere Tand Tdiffer by less than 10&#xb0; C.
