Definitions

  • the present invention relates to a method and an installation for cryogenic distillation.
  • Processes of this type are known from DE-A-3843359 and DE-A-3643359 in which the air of the blowing turbine is cooled by heat exchange with a gas flow enriched with oxygen.
  • SU-A-739316 and SU-A-1231343 disclose air cooling from an insufflation turbine with a nitrogen flow withdrawn from the medium pressure column.
  • EP-A-0 081 473 suggests cooling the expanded air in the turbine insufflation by heat exchange with an air flow intended for the column medium pressure.
  • EP-A-153 673 describes an apparatus in which the supply air flow is cooled by exchanging heat with nitrogen from the top of the column low pressure.
  • FR-A-1 289 009 describes the cooling of the supply air against a flow pumped liquid oxygen.
  • EP-A-0 556 516 describes the cooling of the blown air against rich liquid.
  • EP-A-605 262 proposes to spray the purges under pressure liquid oxygen to avoid the risk of hydrocarbon explosion.
  • the purpose of the present invention is to enhance the frigories contained in a liquid from the double column effectively.
  • an installation is also provided. according to claim 8.
  • Figure 1 shows a nitrogen production plant similar to those described in FR-A-2 578 532, EP-A-153 673 and EP-A-575 591. It includes a heat exchange line 1 and a double column of distillation 2. The latter consists of a medium pressure column 3 operating under a pressure of the order of 8 to 10 bars and a column low pressure operating under a pressure of the order of 4 to 5 bars. Each of these columns has a head condenser 5,6 respectively.
  • a first flow of compressed air 7 at a slight pressure above the medium pressure is cooled near its point of dew through the exchange line 1 and introduced at the base of column 3.
  • the rich liquid in equilibrium with this air, collected in the tank of column 3 is expanded at low pressure in an expansion valve 8 and introduced into a intermediate point of column 4.
  • the descending liquid enriched with oxygen comes to the tank to cool the main condenser 5 to reflux in column 3.
  • Some of the same liquid is again expanded, up to a pressure of the order of 1 bar in an expansion valve 9 then serves to cool the auxiliary condenser 6 to ensure reflux into the column 4.
  • the same liquid after vaporization is sent against the current by a pipe 11 through the exchange line 1 to constitute the waste gas of the installation.
  • the vapor which rises in column 4 is enriched with nitrogen and this is nitrogen which is condensed by the auxiliary condenser 6.
  • a second air flow 12 is expanded in an insufflation turbine 13, cools in the exchanger 14 and is introduced into the lower column pressure 4.
  • a purge liquid flow 15 containing about 82% oxygen is withdrawn from the auxiliary condenser, is pressurized by pump 16 and sent to the exchanger 14 where it vaporizes. The vaporized purge flow is then evacuated of the installation.
  • Nitrogen gas 17 is drawn off at the top of column 4 as product. There is also a small production of liquid nitrogen 18.
  • the low pressure column 4 has no head condenser.
  • the oxygen in the tank of column 4 is withdrawn as product and a liquid purge flow 20 of this tank is vaporized by exchange heat with the blown air, after a possible pressurization step.
  • the purge liquid which is used to cool the air coming from the turbine also could be a purge from another column of the installation (Etienne column, argon column).
