Definitions
- the present invention relates to combined installations of at least one furnace, typically a metal treatment furnace, supplied with compressed air by at least one blower, and at least one air distillation apparatus, also supplied at least with part by said blower, supplying oxygen to the oven and comprising at least one medium pressure column and one mixing column.
- at least one furnace typically a metal treatment furnace
- at least one air distillation apparatus also supplied at least with part by said blower, supplying oxygen to the oven and comprising at least one medium pressure column and one mixing column.
- the object of the present invention is to provide a combined installation of the type mentioned above, allowing reduced operating costs and with greater flexibility in the choice of operating ranges.
- the cryogenic booster / turbine assembly is coupled to an auxiliary assistance member.
- the object of the present invention is also to propose a method for implementing a combined installation comprising at least one oven and an air distillation apparatus comprising at least one medium pressure column and one mixing column, and supplied with air.
- a pressure Pi by at least one blower, in which a part of the air flow supplied by the blower is derived to supply the air distillation apparatus and where part of this derived air is overpressed to supply the mixing column by a booster coupled to at least one cryogenic turbine which expands a fluid in the installation and which serves in particular to keep the distillation apparatus cold, in which assistance energy is supplied to the booster / turbine assembly cryogenic to maintain in the mixing column a pressure P 2 higher by at least 0.3 x 10 5 Pa compared to the pressure Pi without having to take an import part for the turbine ante of the air flow supplying the medium pressure column. 2
- assistance is provided by an electric motor coupled to the shaft of the booster / turbine assembly.
- FIG. 1 is a schematic view of a combined installation according to the invention.
- FIG. 1 there is shown schematically a metal processing furnace, in this case a blast furnace (FM), and an associated air distillation apparatus essentially comprising, in the example shown, an exchange line main LE, a double column with a medium pressure column MP and a low pressure column BP, and a mixing column CM.
- FM blast furnace
- the FM oven and the distillation apparatus are supplied with air by the same blower S delivering into a main compressed air line A supplying at least the FM oven with a large volume of air (typically greater than 100,000 Nm 3 / h) under a medium pressure Pi of less than 6 ⁇ 10 5 Pa, typically between 3 ⁇ 10 5 Pa and 5.5 ⁇ 10 5 Pa.
- Line A can also supply, simultaneously or alternately, another treatment furnace for metal, for example an electric oven with the AOD process.
- From the main line Apart from an air bypass circuit D supplying the distillation apparatus with cooled air then purified in a purification apparatus E, typically of the type by 3 adsorption. Downstream of this purification device E, the circuit D is divided into a first line J for supplying the double column and a second line L for supplying air to the mixing column CM.
- part of the air flow in line J is diverted into the exchange line LE and blown in a cryogenic turbine T to be introduced into the low pressure column BP at the low pressure of this last.
- the turbine T is coupled to a booster C disposed in the line L to boost the compressed air from the blower and send it to the mixing column CM at a pressure P 2 greater than the pressure Pi by at least 0 , 3 x 10 5 Pa and less than 1.5 x 10 5 Pa, typically between 0.4 x 10 5 Pa and 0.8 x 10 5 Pa.
- the booster / turbine assembly CT is assisted by at least one EM motor coupled to the shaft line of the CT assembly.
- the EM motor is of an electric or hydraulic type, as described in the above-mentioned documents.
- the make-up energy is around 30 to 500 W, depending on the characteristics of the combined installation and being inversely correlated to the pressure delivered by the blower S.
