Cold box - the role of this system is to remove nitrogen, hydrogen, carbon monoxide and other impurities in argon gas

1. plate heat exchanger: the product argon and exhaust gas after low temperature distillation through the heat exchanger for cold recovery
And make the crude argon temperature from room temperature down to the temperature required by the working condition (-157 ℃);
2. the main column of the distillation tower: using the principle of low-temperature distillation, the evaporator at the top of the main tower to get 5N standard
Product argon
3. distillation tower II tower: from the top of the main tower to lead a waste gas, because the waste gas contains a large number of argon components.

The cold box is one of the key pieces of equipment in an air separation plant. Therefore, cryogenic separation is a must for all processes in the separation of the product raw gas mixture. Cold box is one of the main equipment for low temperature separation.
It mainly consists of two parts: one is the huge steel shell insulation box, and the other is the internal core aluminum plate-fin heat exchanger.
There are three technical keys, including heat transfer calculation and mechanical structure design and hydraulic calculation. The three need to be closely coordinated to meet the process requirements and to achieve high efficiency, pressure resistance, material saving, compactness, low flow resistance and low heat (cooling) loss.
