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).
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.
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.
Abstract:
A blast furnace (1) is supplied with a flow of optionally oxygen-enriched air coming from an isothermal compressor (3) or a (radial) centrifugal compressor (11).

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.
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.
