Definitions

  • the present invention relates to an installation for supplying gas under high pressure to at least one user station, of the type comprising an insulated tank for storing gas in at least partially liquid form having an upper part and a lower part, and a supply line comprising an evaporator extending between the lower part of the first tank and the user station, see for example US-A-4,961,325.
  • gas sources In many industrial sectors, the current trend is to require gas sources at increasingly higher pressures. For industries consuming large quantities of gas, the latter is generally brought into the gas phase at high pressure by a compressor, the gas being produced in situ by a gas production unit, generally by cryogenic separation. For lower gas consumption, the latter is generally stored in liquid form at low pressure, vaporized and pressurized.
  • the object of the present invention is therefore to propose a compact gas supply installation, of particularly simple and efficient design, with "static" operation, requiring no compression member or auxiliary energy and making it possible to supply instantaneously, possibly on request, a gas under high pressure, in particular at a super-critical pressure, in particular, but not exclusively, as backup for a main installation for supplying this gas under high pressure.
  • the installation comprises a first fluid circuit starting from the lower part of the tank, comprising, in series, a pressure control valve and a first exchanger in heat exchange relationship with the fluid in the tank and ensuring that it is kept cold.
  • the gas is maintained, typically in a super-critical state, at a pressure P s substantially less equal to the operating pressure P u and can thus be instantly supplied to said pressure at the user station.
  • the installation for supplying a gas under high pressure, typically oxygen or nitrogen, to at least one user station A comprises a tank 1 thermally insulated internally or externally , from the lower part from which a supply line 2 extends to the user station A through a heater or evaporator 3.
  • a first fluid circuit 4 comprising an inlet and closing valve 5 controlled by the pressure prevailing in the tank 1 and passing through a heat exchanger 6 in heat exchange relation with the fluid in the tank and arranged, as in the embodiment shown, inside the tank 1, in thermal contact with the fluid in the tank, possibly through the wall of the envelope.
  • the circuit 4 extends, outside the tank 1, to an outlet 7 for venting or connection to a circuit for using gas under pressure low or medium, or recycling to a main production unit, as we will see later.
  • a second circuit 8 joining the upper part of the tank 1 and comprising, in series, a heat exchanger 9, for example of the atmospheric type and a valve with control of pressure 10 sensitive to the pressure prevailing in the reservoir 1.
  • the latter also comprises a filling pipe 11 connectable to a source of the gas under high pressure or to an assembly consisting for example of a reservoir of said liquefied gas under low pressure 12 and a low pressure high pressure pump 13.
  • a non-return valve 14 is provided in the supply line 2, downstream of the vaporizer 3.
  • the tank 1 is provided, at its upper part, with a pressure relief valve 15 .
  • the first circuit 4 exploiting the non-expanded stored cold fluid makes it possible to recover the frigories of the fluid vaporized in the tank 1 by the heat inlets to cool the fluid in the tank and thus maintain it at the required low temperature and therefore at the desired pressure.
  • the second circuit 8 maintains the required high pressure of the fluid in the reservoir 1. It will be understood that, the fluid being permanently in the reservoir 1, at a high storage pressure P s equal or slightly lower than the nominal pressure P u required for user station A, gas at substantially the same pressure can be sent instantly to user station A.
  • the autonomous installation which has just been described finds a particularly advantageous installation as an emergency installation for a high-capacity gas production source 30, for example a cryogenic unit 31 producing, at one of its outputs 32, the gas of use under a medium pressure which is brought, by a compressor 33, to the pressure of use P u and conveyed, by a pipe 34, provided with a non-return valve 35, communicating with the downstream end of supply line 2, to user station A.
  • a cryogenic unit 31 producing, at one of its outputs 32, the gas of use under a medium pressure which is brought, by a compressor 33, to the pressure of use P u and conveyed, by a pipe 34, provided with a non-return valve 35, communicating with the downstream end of supply line 2, to user station A.
  • the working gas is typically nitrogen or oxygen, in which case the production unit 30 is a cryogenic air distillation unit.
  • the installation according to the invention must have a useful quantity stored per m 3 of storage capacity under said pressure of approximately 820 kg / m 3 and at a temperature of approximately -150 ° C., i.e. a tank volume 1 of approximately 20 m 3 .
