  • Air distillation plant comprising a plurality of cryogenic distillation units of the same type
    Patent number: 6128921
    Abstract: In this plant (1), a common thermal insulation wall (14) surrounds first and second distillation units (2, 3, 4, 5). A first product stream is removed from the first unit and a second stream is removed from the second unit, the first and second streams are mixed without having previously been compressed or expanded with the production of external work.
    Type: Grant
    Filed: February 8, 1999
    Date of Patent: October 10, 2000
    Assignee: L'Air Liquide
    Inventors: Alain Guillard, Bernard Saulnier
  • Process and installation for the supply of an apparatus for separating air
    Patent number: 6067817
    Abstract: Air is supplied to an air separation apparatus via a heat exchanger in which the entering air is cooled against an air gas separated in the separation apparatus. The air is first compressed in an adiabatic compressor. The air gas separated in the separation apparatus is humidified after it leaves the separation apparatus but before it reaches the heat exchanger.
    Type: Grant
    Filed: December 30, 1997
    Date of Patent: May 30, 2000
    Assignee: L'Air Liquide, Societe Anonyme pour L'Etude et L'Exploitation des Procedes Georges Claude
    Inventors: Didier Magnet, Emmanuel Garnier, Bernard Saulnier, Jean-Louis Girault
  • Process for feeding a gas-consuming unit
    Patent number: 6062043
    Abstract: A gas-consuming unit (HF) is fed partially by a flow delivered directly by a compression unit (21) and partially by one delivered by a separation apparatus (25) which is itself fed by a flow delivered directly by the compression unit. Another flow produced by the separation apparatus, but at lower pressure, is returned to a compression unit before being sent to the consumer unit.

  • Process and assembly for the compression of a gas
    Patent number: 5481880
    Abstract: Cooling water for compression apparatus (1) is cooled by an air-refrigerated apparatus (18). Makeup water which is cooler than the water treated by this apparatus passes first through a heat exchanger (8) mounted on the delivery conduit of the compression apparatus, then supplies the refrigeration apparatus (18). Use in air distillation installations.

  • Process and apparatus for the liquefaction of a flow of gaseous oxygen
    Patent number: 5060480
    Abstract: Gaseous oxygen to be cooled passes through an exchanger which is cooled with compressed liquid nitrogen, at least a portion of the vaporized nitrogen which is warmed up in the exchanger being treated in a turbine and thereafter reintroduced into the exchanger. Application for example to the storage in liquid form of excess oxygen under pressure conveyed by a distribution network with variable load.
