Process and high pressure gas supply unit for an air constituent consuming installation.

摘要

According to this process: air is distilled in a distillation apparatus (13) associated with a heat-exchange line (11) through which a heat-generating fluid is circulated under high pressure; a store (23) is fed, at least intermittently, with gas in liquid form; and gas in liquid form withdrawn from the store is brought to a vapourisation pressure, and it is vapourised under this pressure in the heat-exchange line (11). Application to supplying oxygen, nitrogen and argon under pressure to stainless steel production installations such as electric arc furnaces associated with an AOD process.
