Definitions

  • the present invention relates to a method and installation of separation of a gaseous mixture, for example air, by cryogenic distillation according to the preamble of claims 1 and 11, respectively.
  • a method and such an installation are known from JP-A-49 117 364 and US-A-2 711 685.
  • the invention relates in particular a process for producing gas under pressure.
  • JP-A-49117364 suggests spraying part of the liquid intended for the pump in a dedicated exchanger to produce the gas of barrage.
  • An object of the invention is to simplify the installation.
  • an air flow 1 to 6 bar is sent to the exchanger 3. After partial cooling, it is divided into two. Flow 5 continues cooling and liquefies in the exchanger, while the flow 7 is expanded in a Claude turbine and sent to a double column comprising a medium pressure column 9 and a low pressure column 11. Liquefied flow 5 is split between the two columns of the double column or sent to a single columns.
  • a flow 13 enriched in oxygen is withdrawn from the bottom of the column medium pressure 9 and sent to an intermediate point in the lower column pressure 11.
  • a flow of liquid nitrogen is sent from the medium pressure column at the head of the low pressure column.
  • a flow 15 containing at least 80% oxygen is withdrawn from the the low pressure column 11, pressurized to 30 bar in the pump 17 and sent in the exchanger 3 where it vaporizes and heats up to room temperature.
  • Part 21 of this flow is sent as barrier gas to the pump 17.
  • the barrier gas can come from a gas network 18 under pressure having the same main component as flow 15 but also being pure or purer than this flow.
  • This network gas can be used as a barrier gas if its pressure is higher than that of suction from pump 17.
  • the external source can be a liquid storage 20 other than a column of system distillation. The liquid is then vaporized either in the exchanger 3 or in a dedicated exchanger after a possible pressurization step to supply the pump barrier gas 17.
  • the residual nitrogen 19 of the low pressure column heats up in the exchanger 3.
  • the same barrier gas is sent to the pump 23 which is used to send liquid oxygen to storage 25 and to pump 27 of the film vaporizer connecting the medium pressure column and the low pressure column and to the pump 29 of rise of rich liquid.
  • the same barrier gas can also be sent to the pump that transfers liquid oxygen from the low pressure column tank to the - condenser at the head of the medium pressure column.
  • the pressurized liquid sent to the top of the mixing column can come from a pump whose barrier gas is common to all other pumps.
  • barrier gases possibly of different purities rather than a common barrier gas for all pumps for pressurizing a liquid with the same component main.
  • barrier gas is common, its purity is equal to or higher than the purest liquid pressurized by a system pump which it serves as a barrier gas and its pressure is greater than the pressure of the pump with the highest suction pressure it serves dam gas.
  • the pumped liquid will be rich in oxygen but it is also known to pump liquids rich in nitrogen or argon or in the processes of separation of mixtures of hydrogen, of monoxide of carbon and methane, into methane.
  • the barrier gas has the same main component than the pumped liquid or even, in addition, that it is at least as pure as this liquid, if not more pure.
  • the barrier gas may have a very different from the pumped liquid.
  • oxygen does not must especially by containing nitrogen whereas the presence of argon is not harmful; for other applications the opposite is true.
  • a gas rich in argon or nitrogen can serve as barrier gas. Even air can sometimes act as a barrier gas.
  • an external source of liquid oxygen (therefore a external source other than a system column) is connected to means to vaporize at least some of this liquid and means to send the steam thus formed at the first pump to serve as barrier gas.
  • an external source of a gas is constituted by a pipe of purer oxygen than the liquid to be pumped from a network.
  • the pipe is connected to means to send this pressurized gas to the first pump to serve as barrier gas.
