FIELD: cryogenic engineering; plants for production of argon by low-temperature rectification. SUBSTANCE: to reduce concentration of nitrogen in mixture of argon, nitrogen and oxygen in low-pressure column maintaining concentration of argon close to maximum value, device for discharge of liquid flow is connected with low-pressure column at point below the stage where concentration of argon in column is maximum by at least five equilibrium stages. Packing in low-pressure column is located above point of connection of device for discharge of liquid flow. EFFECT: enhanced efficiency. 7 cl, 6 dwg
