摘要： The invention concerns a method for operating a production plant comprising at least one treatment unit (3) of at least one gas product, supplying at least a fluid to a consumer (2), and electrically-powered, which consists in: operating the treatment unit during periods when electric power costs more than a first predetermined threshold and during periods when electric power costs less than a second predetermined threshold, the first threshold being not lower than the second threshold; during at least one period when electric power costs more than the second threshold, at least part of the fluid is stored in at least a storage facility (9), in liquid and/or gas form; during a period when electric power costs more than the first threshold, the fluid is supplied to the consumer from at least one storage facility, after an evaporation step if it is stored in liquid form; during a period when electric power costs less than the second threshold, producing at least one fluid having a predetermined purity, a predetermined flow rate, a predetermined temperature and a predetermined pressure in the treatment unit; and during a period when electric power costs more than the first threshold, the consumption of the treatment unit is reduced and the fluid is produced with purity lower than the predetermined purity and/or flow rate lower than the predetermined flow rate and/or temperature lower than the predetermined temperature and/or pressure lower than the predetermined pressure.

摘要： In order to boost production of a product (A) of an existing separation plant (X,1), an additional plant (Y) is integrated with the original plant so as to enable the original plant (X) to produce more of that product (A+B), whilst the additional plant may or may not necessarily itself produce the same product directly. For example, air is separated in a first unit, which is an existing double column distillation plant, to produce an oxygen rich fluid. So as to increase the production of the oxygen rich fluid, a second unit, which is a wash column (15), is integrated with the first unit. Air (41) is separated in the single nitrogen wash column (15) to remove oxygen and gaseous nitrogen (42) is produced at the top of the column. The wash column is fed with liquid nitrogen (39) from the high pressure column (25) of an existing air separation unit.

摘要： The invention concerns a method which consists in using only two adsorbers which follow each a phase-shifted cycle successively consisting in an adsorption phase, at high pressure of the cycle, and a regeneration phase, ending in repressurizing of the adsorber. The method comprises a step which consists in paralleling the adsorbers in adsorption phase for a predetermined time interval much longer than the switching time of the valves controlling the adsorbers starting said step and/or as long as the difference in temperature between that of a total flux and that of a first flow rate is greater than a predetermined threshold temperature. The invention is applicable to air purification before distillation.

摘要： The invention concerns a combined installation of fluid producing apparatus (P) with a main air compressor (44) and a fluid consuming unit (2), wherein a gas coming from the unit is expanded in a turbine (10, 20, 30, 40, 150) or another device capable of generating mechanical energy driving the compressor (14, 24, 34, 44, 154). Another turbine or device can expand another gas or the same gas coming from the unit to drive another compressor.

摘要： A plant which, when used to produce pressurised oxygen gas, includes a switch, e.g. a liquid oxygen/liquid air switch, for meeting relatively long-term peak demand as well as short-term, high-amplitude peak demand, and a circuit (13, 30) for compressing oxygen to a pressure higher than the production pressure. Said circuit leads to a buffer (15) at least partially meeting short-term, high-amplitude peak demand.
