Definitions

  • An aim of the invention is to simplify the refrigerant fluid circuit (water or glycolated water in general) in the case of heat recovery only on at least one cooler of a compressor.
  • the warmer flow is sent to a unit where it preheats water.
  • the invention is described for a two-stage compressor, but can easily be extrapolated to more than two stages.
  • the refrigerant is described as water, but can also be glycolated water or any other suitable refrigerant.
  • the compressor comprises at least two stages, including a final stage and at least one intermediate stage or a first stage, in the case of a two-stage compressor only.
  • the compressor includes a cooler with a temperature rise of the refrigerant, for example water) around 10°C (or 30°C for water at 20°C).
  • the compressor includes another chiller to make hot refrigerant, for example hot water, with a refrigerant temperature rise, for example water around 70°C (or 90°C for water at 20°C), with a very low refrigerant flow rate.
  • a refrigerant temperature rise for example water around 70°C (or 90°C for water at 20°C)
  • the flow ratio between the flow sent to the chiller with a smaller refrigerant temperature rise and the flow sent to the chiller with a larger refrigerant temperature rise is between 5 and 15.
  • the compressor produces a flow of warm refrigerant, for example warm water, and a flow of hot refrigerant, for example hot water.
  • the hot refrigerant has been heated by an intercooler or first cooler and the warm refrigerant has been heated by an aftercooler.
  • the compressed gas in the last stage of the compressor may be at a higher temperature than the compressed gas in the intermediate stage or first stage.
  • the opposite is recommended. While the compressor's performance is not optimal in terms of energy, the use of the heat thus recovered largely compensates for the drop in machine performance, for an overall energy balance which is then improved.
  • a method for separating air by cryogenic distillation in which air is compressed according to one of the methods as described above, the compressed air is cooled, purified in a pressure and/or temperature swing adsorption purification unit and separated by distillation forming a fluid enriched in oxygen and/or nitrogen, the purification unit being regenerated by a regeneration gas.
  • a method for separating air by cryogenic distillation in which air is compressed, the compressed air is cooled, purified in a purification unit by pressure and/or temperature swing adsorption, a part of the purified air is compressed according to one of the methods as described above and separated by distillation forming a fluid enriched in oxygen and/or nitrogen, the purification unit being regenerated by a regeneration gas.
  • an apparatus for compressing a gas, associated with a heat-consuming element comprising a compressor having at least two stages, including an intermediate or first compression stage and a final compression stage for compressing a gas downstream of the intermediate or first compression stage, an intermediate cooler for cooling the gas downstream of the intermediate or first compression stage and a final cooler for cooling the gas downstream of the final compression stage, means for dividing a refrigerant, for example water or glycolated water, coming from a source of the refrigerant or from a system for cooling the refrigerant into a first flow and a second flow, a conduit for sending the first flow to cool only the intermediate cooler and a conduit for sending the second flow to cool only the final cooler, a conduit for leaving the first flow heated from the intermediate or first cooler and a conduit for leaving the second heated from the final cooler, the first and second heated flows being at temperatures which differ by at least 30°C, preferably at least 40°C, or even at least 50°C, the first heated flow being hotter than the
  • the gas G for example air
  • a compressor comprising at least two stages C1, C2.
  • the gas compressed in stage C1 is then cooled in a cooler R1 by a refrigerant 21 to a temperature between 15 and 25°C which may be water or glycolated water.
  • the refrigerant 21 is heated in the cooler R1 to 90°C.
  • the R2 final cooler is typically a cross-flow shell and tube exchanger with a few passes. Its standard design allows for good gas cooling at the end of compression. If heat recovery had been used on this final refrigerant, the gas would have been poorly cooled, or a second refrigerant would have had to be added in series.
  • Cooling system B provides a refrigerant, for example cold water 1.
  • This system can be connected to a cooling network and/or to an atmospheric cooling tower (for example open, closed, air cooler, evaporative or adiabatic type) and/or an adsorption or absorption refrigeration unit.
  • the cooling system is preferably a closed circuit to control the quality of the water and avoid problems of corrosion and/or deposits, which are accentuated by the high temperature at the outlet of the intermediate refrigerant.
  • the refrigerant for example cold water 1 preferably has a temperature close to the dry or wet bulb temperature of the ambient air.
  • a portion 11 of the refrigerant 1 goes to the final cooler R2 to cool the compressed gas G in the final stage C2 of the compressor.
  • the refrigerant is described as water but it will be understood that it can be a mixture of water and glycol or ammonia.
  • the cold water is heated in the aftercooler R2 and exits as lukewarm water 12 with a moderate temperature rise, typically between 5°C and 15°C.
  • This part 11 can also be used to cool the compressor motor, the compressor oil sump and possibly other auxiliaries on the compressor.
  • Another portion of the cold water 21 goes to the intercooler R1 to cool the compressed gas G in the stage C1 of the compressor.
  • the cold water is heated in the final cooler R2 and leaves in the form of hot water 22, at a temperature typically between 50°C and 100°C above the temperature at which it arrives in the cooler R1, preferably around 90°C.
  • This mixture 2 is then sent to the cooling system B.
  • another variant consists of passing the regeneration fluid during the heating phase through an exchanger against the hot fluid and not passing the regeneration fluid during the cooling phase through an exchanger against the hot fluid, the hot fluid circulating in the exchanger during the heating and cooling phases.
  • the regeneration fluid circuit has a second exchanger, typically an electric, steam or gas heater to provide either additional heating to reach a higher temperature and/or to enable the adsorption system to operate during operating phases where the compression heat is not available, for example during the start-up phase if the compressor is stopped.
  • a second exchanger typically an electric, steam or gas heater to provide either additional heating to reach a higher temperature and/or to enable the adsorption system to operate during operating phases where the compression heat is not available, for example during the start-up phase if the compressor is stopped.
  • the 3-way valve V can be a control valve which adjusts the flow rate in each outlet 22a and 22b so as to finely regulate the temperature of the fluid 31 at the outlet of the exchanger H1, in particular if the heater (and its associated temperature control regulation) is not used.
  • the regeneration fluid 30 is heated only using the heater H2.
  • the regeneration fluid 30 is heated only using the heater H2.
