Product Description

                   Cryogenic Air Separation Plant for Liquid Oxygen Nitrogen Gas Making
Cryogenic Liquid Oxygen Nitrogen Gas Generation Equipment Air Separation Unit: liquid oxygen nitrogen making plant
Air Separation Equipment
The air separation plant separates atmospheric air into its primary components, typically nitrogen and oxygen, and sometimes also argon and other rare inert gases. The most common method for air separation is cryogenic distillation. Cryogenic air separation units are built to provide nitrogen or oxygen and often co-produce argon.It uses mature cryogenic rectification technology. Our factory developed and designed a full-low pressure molecular sieve to purify the air and turbo expander refrigeration process to further reduce the energy consumption of small and medium sized air separation plants.

According to the compression style, it divide into:

1. Internal Compression

The internal compression process is to cancel the oxygen compressor and directly replace it with a liquid oxygen pump and an air booster. The liquid oxygen is extracted from the main condensing evaporator of the air separation plant rectification tower, and the pressurized by the liquid oxygen pump to required pressure, and then a high pressure air exchanges heat with liquid oxygen to vaporize it out of the cold box as a products gas.

1. External Compression:

Its process directly produces low pressure oxygen from the rectification column, and then reheats the cold box through the main heat exchanger and then pressurizes it to the required pressure through the oxygen compressor to supply the user. Also called normal air separation.
