Abstract

The invention discloses a system for increasing the yield of liquid argon. The system comprises a first crude argon column, a second crude argon column, a buffer tank and a pure argon column. The first crude argon column is connected with the second crude argon column; the second crude argon column is connected with the buffer tank; and the buffer tank is connected with the pure argon column. The first crude argon column performs oxygen and argon separation on argon fractions with the oxygen content ranging from 88% to 92%, which are extracted in the middle of an upper column of an air separation system, and transmits crude argon with the oxygen content smaller than 3%, which is obtained after separation, to the second crude argon column. The second crude argon column performs oxygen and argon separation on the received crude argon with the oxygen content smaller than 3% again and outputs argon obtained after separation, of which the oxygen content is smaller than 3ppm, to the buffer tank. The buffer tank stores the received argon with the oxygen content smaller than 3ppm and outputs the argon to the pure argon column after the flow and the pressure are balanced. The pure argon column performs oxygen and argon separation on the received crude argon with the oxygen content smaller than 3%, which is output by the buffer tank, to extract pure liquid argon products. By means of the system, the yield of liquid argon can be improved.

Description

technical field [0001] The invention relates to the technical field of liquid nitrogen extraction, and more specifically, relates to a system and method for increasing the output of liquid argon. Background technique [0002] At present, in the production of the air separation system, the adjustment of the argon system requires stable working conditions of the main tower, high purity of oxygen and nitrogen products, and sufficient cooling capacity. In operation, it will more or less affect the normal production of oxygen in the large air separation system. In addition, the argon content in the atmosphere is low, and it takes about 48 hours from the adjustment of the purity of the argon fraction to the generation of product argon. The adjustment time Long and low yield. Therefore, in most air separation industries, liquid nitrogen products are seldom modulated. Even if the liquid nitrogen product is modulated, the output of the liquid nitrogen modulated by the existing liqu...
