  • Process and plant for the production of argon by cryogenic distillation of air
    Patent number: 11441840
    Abstract: 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.
    Type: Grant
    Filed: July 31, 2019

  • Process and apparatus for producing gaseous oxygen by cryogenic distillation of air
    Patent number: 9976803
    Abstract: Process for producing gaseous oxygen by cryogenic distillation of air, wherein a portion of the feed air flow is brought to a pressure P1, by means of a first compressor, the suction temperature T0 of which is between 0 and 50° C., the gas at the pressure P1 is cooled, in order to generate an air stream at the pressure P1 and the temperature T1 between 5 and 45° C., a portion of the air compressed in the first compressor undergoes an additional compression step starting from the temperature T1 and pressure P1 to a pressure P2 greater than P1, then is cooled, to the temperature T2 where T2 and T1 differ by less than 10° C.
