Process description(see drawing for ref.)

The plant is of molecular sieve purification system, normal flow,cryogenic process.

Air is sucked via filter and goes to air compressor. After cold blow out through stage by stage it goes to air precooling system and after condensing water is separated in water separator, it enters absorbing drum of purification system for removal of moisture, CO2, and carbon hydrogen, etc. After purified, it enters heat exchanger in rectification column cold box where it has heat exchange with O2, N2 and waste nitrogen in reflux. Part of air via throttling, it goes to the lower column. The other part of air is abstracted from the middle part of heat exchanger and goes to expansion turbine for production of cold. After expansion, low tempt. air enters upper column(or part of it enters waste nitrogen pipe to be reheated and to be vented)and is priliminerily separated in lower column. Liquid nitrogen is at the top of the lower column and liquid air is at the bottom of the lower column;. Liquid air is abstracted from the bottom of the lower column and goes through subcooler to the middle part of upper column.Liquid nitrogen is abstracted from the top of the lower column and goes through the subcooler to the top of upper column. Afater air is efficiently rectificated in the middle part of the upper column,liquid oxygen is abstracted from the bottom of the upper column as product oxyxgen. Product oxygen goes through heat exchanger to be reheated and is discharged out of the cold box. According to the need of the customer, product oxygen goes through balloon for buffering and is conpressed in oxygen compressor. It is delivered through pipe to the customer or for filling of the cylinders.

Nitrogen is abstracted from the top of the upper column and goes through LN2 subcooler and heat exchanger to be reheated to be discharged out of the rectification column to be vented or is compressed by nitrogen comressor via pipe to be delivered to customer or be filled into cylinders for saling. Waste nitrogen is absstracted from waste nitrogen opening at the top of upper column and is reheated via heat exhcanger to purifier to be used as regeneration gas or to be vented.

Process features:

* All lower pressure, purificationsystem for purifying of theair, air bearing expansion turbine for production of cold, aluminium plate-fin heat exchange process increase the satability, saftey and reliability of plant operation.

* Few equipment and less space for the plant. Simple operation, conveniency, all data is supervised by online digital display instrument reduce the operation persons.
