Output, purity and pressure

Description:

        The air is compressed with feed compressor, and goes into pre-cooling unit to be cooled to 8~10, and then it is purified through molecular sieve purifier where the impurities like moisture and CO2 are removed.

        The purified compressed air goes into the boosting end of expander to enhance the pressure, and then it is cooled to below 40 with water cooler, after which it goes into main heat exchanger.

When the air is cooled to 253K, it goes into cryogenic chiller to be cooled to 243K, and then it refluxes to main heat exchanger, and when it is continuously cooled to 140K, most air will be extracted from main heat exchanger to the turbo expander for expansion refrigeration. The expanded air refluxes to main heat exchanger to be rewarmed, after that part air goes to the molecular sieve for regeneration, and the rest air goes to the inlet of air compressor for next circulation.

        The rest air is continuously cooled and liquefied in the main heat exchanger, and subcooled to 0.5MPa(G) after going out of the cold end of main heat exchanger, by which the subcooling liquid air is obtained.

Applications:

1.Petroleum refining

2. Refrigerant

3. Extract liquid oxygen, liquid nitrogen and rare gas

4. Aerospace

5. Source of energy

6. Glassmaking

Competitive Advantage:

1. Successful experience of made many plants

2. No air loss and high yield

3. Leading technical level, perfect technical development group

4. The system is designed for long-term operation, that is, the adsorber will be in operation for 4 hour so that the service life of molecular sieve and valves can be lengthened, the loss in switching-over is reduced and the main column can be kept in steady operation because the frequency of pressure fluctuation

5. Our company’s economic effectiveness is in the lead of the industry in China
