Cryogenic Air Separation Plant(ASP)

Cryogenic Air Separation Plant is widely used in Petro-Chemical Industry and Iron & Steel Industry.

Generally two different processes are available:

INTERNAL COMPRESSION PROCESS

LOX is pumped and vaporized in the cold box and send to user as GOX products. Such kind of process is especially used to meet the customer's large demand of liquid product and the requirement for the high pressure of oxygen and nitrogen products in the chemical industry. Technology of molecular sieve pre-purification, high/medium pressure Heat exchangers, structural packing upper column and full rectification argon recovery is used in the air separation unit with such process, which has got the features of stable reliable and safe operation, big output of liquid product, high pressure of oxygen and nitrogen products with different level as required.

EXTERNAL COMPRESSION PROCESS

A typical kind of process that the low-pressure oxygen is produced by the plant and then compressed by the oxygen turbo compressor to the required pressure as the oxygen product. Such kind of process is specially applied in the metallurgical industry for the requirements that oxygen pressure is ≤3.0Mpa (G) and the demand of liquid product is ot much. The technology of molecular sieve pre-purification, full low-pressure Heat exchangers, expanded air to the upper column, structural packing upper column and full rectification argon recovery are used in such process, which has got the features of strong variable-load capability; stable and reliable running, flexible and convenient operation, more homemade parts and accessories and lower investment cost.
