Abstract
The combined installation comprises at least one metal production unit (II), including at least one, and typically a series of metal production or treatment units (1-6), and at least one air gas separation unit (III) including at least one outlet for at least one air gas (14-18), the units being supplied with compressed air with a low water vapor content by a common compressed air production unit (I), and with at least one of the gas outlets (14-18) from the separation unit (III) connected to at least one of the devices (1-6) of the production unit, to supply the latter with gas.

A combined installation comprising:
- at least one metal processing unit having at least one air inlet and at least one gas inlet;
- at least one air separation unit having at least one air inlet and at least one gas outlet;
- an air compression unit having at least one compressed air outlet, and
- first air conduit means extending from said compressed air outlet to the air inlet of said metal processing unit for supplying said metal processing unit with compressed air from said air compression unit, and
- second air conduit means extending from said compressed air outlet to the air separation unit for supplying said air separation unit with compressed air from said air compression unit.
A method of operating a metal processing plant including at least a first metal processing unit for processing at least one metal while utilizing a flux of air, and at least one air separation unit for supplying at least one gas separated from air to at least one unit in the plant, which comprises providing and operating at least one air compressor unit for separately supplying air under pressure to said first metal processing unit and to said air separation unit.
