Description:


The proposed plant employs a process in which air is purified by molecular sieve and waste nitrogen is refluxed and expanded.

 Following the elimination of dust and other mechanical impurities from process air in an air filter, the process air enters air compressor where it is compressed to the rated pressure. The compressed air enters precooling system to be cooled to the temperature to the benefit of adsorbtion.

 The pre-cooled air enters one of molecular sieve adsorbers where such impurities contained in air as moisture, CO2, C2H2 and hydrocarbon are adsorbed by molecular sieve.

 The purified air out of adsorber enters main heat exchanger in which the temperature reduced gradually; out of main heat exchanger, the cooled air reaches the saturated temperature and enters the bottom of nitrogen column to take part in rectification.

 Air rises in nitrogen column to be condensed continually, of which the nitrogen content increased, and the product nitrogen gas is obtained at the top. The nitrogen gas drawn out of the top of column enters main heat exchanger, and then it is supplied to client after being rewarmed. The rest of nitrogen gas at the top of column enters condenser evaporator to be condensed as liquid nitrogen. The liquid nitrogen flows back to nitrogen column as refluxed liquid to take part in rectification, and it evaporates gradually while the oxygen content increases, and oxygen enriched liquid air is obtained at the bottom.

The liquid nitrogen is fed into liquid nitrogen storage tank SV1 to be supplied to client as the product liquid nitrogen.

 Oxygen-enriched liquid air enters liquid air subcooler to be subcooled and throttled to be fed into condenser evaporator. Oxygen-enriched liquid air is vaporized to be oxygen-enriched air in condenser evaporator and then the oxygen-enriched air to be fed out of the top of column and into main heat exchanger to be warmed. The warmed air is fed out of the middle portion of main heat exchanger and into turbo-expander to be expanded and refrigerated.

 Expanded oxygen-enriched air enters main heat exchanger to be fed out of cold box after to be rewarmed.

 Part of oxygen-enriched air fed out of cold box enters electric heater to be warmed, and then enters another molecular sieve adsorber as the regenerated gas for molecular sieve adsorber, and the rest is discharged.
