Plant for the production of argon by cryogenic distillation, comprising an argon separation column, means for sending a gas containing argon and oxygen to the argon separation column, means for extracting a fluid enriched in argon at the top of the argon separation column, means for extracting a liquid enriched in oxygen at the bottom of the argon separation column and at least two storage tanks, positioned one above the other, each storage tank being connected to two different intermediate levels of the argon separation column by two pipes, the two storage tanks being contiguous.

Process and plant for the production of argon by cryogenic distillation of air

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.
