Definitions

  • the present invention relates to a method and a installation for power supply for a air separation.
  • Air separation devices are typically supplied with air from at least one isothermal compressor fitted with inter-stage refrigerants in which the air is cooled by heat exchange with refrigeration air.
  • the air leaving the compressor is itself cooled in a final cooler or in an air / water tower, generally associated with a water / nitrogen tower and / or a group refrigerator.
  • This system generally called “precooling” provides air at a relatively low temperature (around 15 ° C) before direct to desiccation also limiting the size of the latter, the quantity of water contained in the air at increasing exponentially with temperature.
  • precooling provides air at a relatively low temperature (around 15 ° C) before direct to desiccation also limiting the size of the latter, the quantity of water contained in the air at increasing exponentially with temperature.
  • the compressors used are compressors isothermal.
  • EP-A-0069454 describes the use of a compressor adiabatic to power a separation device air, the compressed air then being cooled by water at high pressure.
  • the cost of installation is reduced by eliminating water refrigerants on the circuit supply air to the gas separation unit the air as well as the entire water circuit of associated cooling, including among others, towers water refrigeration, water treatment, pumps system, the distribution network, the taps, the power supplies and associated instrumentation, and finally the air water precooling system supplying the air gas separation unit.
  • This invention also has the advantage of reducing operating costs by a significant reduction of water consumption, by eliminating the costs of maintenance of the water network associated with the removal of possible corrosion problems of the water circuit and the periodic replacement of certain components (refrigerants, etc.) and by removing the power consumption of water pumps and water cooling tower fans.
  • All air for air separation unit A is compressed by an adiabatic air compressor 1.
  • the air tablet is at 200 ° C and must be cooled by exchange of heat with all or part of the products leaving separation device A and possibly by passage in an absorption refrigeration unit or by water cooler.
  • impure nitrogen 3 from device A cools the air which passes into the exchanger 5.
  • the air is then purified in the purification unit 7, which is regenerated by part of the impure nitrogen reheated in the exchanger 5.
  • the impure nitrogen can be saturated with water upstream of the exchanger 5 which causes a drop in the temperature thereof and thereby increases its capacity to cool the incoming air (see arrow H 2 O in dotted lines) .
