  • Patent number: 6576040
    Abstract: All of the air is compressed in a single compressor, which feeds a smelter for smelting ore, a converter for converting matte coming from the smelter and an air separation unit which delivers two oxygen streams for enriching the air. A buffer tank is used to deliver a variable flow of enriched air to the converter.
    Type: Grant
    Filed: September 18, 2001
    Date of Patent: June 10, 2003

  • Publication number: 20020033566
    Abstract: All of the air is compressed in a single compressor (1), which feeds the smelter (2) for smelting the ore, the converter (6) for converting the matte coming from the smelter (2) and an air separation unit (4) which delivers two oxygen streams (9, 10) for enriching the air. A buffer tank (7) is used to deliver a variable flow of enriched air to the converter (6). Application to the production of copper.

  • Patent number: 6129778
    Abstract: In a process for supplying unit (9) that consumes a gas at several pressures, the gas is produced at the highest pressure and is sent to the unit. When the consumption of the unit falls, at least one portion of the high pressure gas is stored in an accumulator (5).

  • 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.

  • 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.
