Definitions
- the present invention relates to a method and a installation for power supply for a air separation.
- Air separation devices are typically supplied with air from at least one isothermal compressor fitted with inter-stage refrigerants in which the air is cooled by heat exchange with refrigeration air.
- the air leaving the compressor is itself cooled in a final cooler or in an air / water tower, generally associated with a water / nitrogen tower and / or a group refrigerator.
- This system generally called “Precooling” provides air at a relatively low temperature (around 15 ° C) before direct to desiccation also limiting the size of the latter, the amount of water in the air increasing exponentially with temperature.
- Precooling provides air at a relatively low temperature (around 15 ° C) before direct to desiccation also limiting the size of the latter, the amount of water in the air increasing exponentially with temperature.
- the compressors used are compressors isothermal.
- a method is provided supply for an air separation device in which at least one of the air compressors is a adiabatic compressor.
- a installation for supplying a air separation in which at least one of the compressors air is an adiabatic compressor.
- a method for feeding a separation device air by cryogenic distillation in which at least one part of the air intended for device A is cooled in an exchange line by a flow of an air gas, in particular impure nitrogen coming from the apparatus of separation characterized in that the flow of a gas from the air is humidified before entering the exchange line.
- a installation for supplying a air separation by cryogenic distillation comprising means for sending an air flow and an air gas to an exchange line, characterized in that it comprises means for humidifying the gas in the air upstream of the exchange line.
- the cost of installation is reduced by eliminating water refrigerants on the circuit supply air to the gas separation unit the air as well as the entire water circuit of associated cooling, including but not limited to towers water refrigeration, water treatment, pumps system, the distribution network, the taps, the power supplies and associated instrumentation, and finally the air water precooling system supplying the air gas separation unit.
- This invention also has the advantage of reducing operating costs by significantly reducing the water consumption, by eliminating the costs of maintenance of the water network associated with the removal of possible corrosion problems of the water circuit and the periodic replacement of certain components (refrigerants, etc.) and by removing the power consumption of water pumps and water cooling tower fans.
- All air for air separation unit A is compressed by an adiabatic air compressor 1.
- the air tablet is at 200 ° C and must be cooled either using a water cooler (direct contact or not) or by heat exchange with all or some of the products products leaving separation device A either by passage in an absorption refrigeration unit either by many of these systems.
- impure nitrogen 3 from device A cools the air which passes into the exchanger 5.
- the air is then purified in the purification unit 7, which is regenerated by part of the impure nitrogen heated in the exchanger 5.
- the impure nitrogen can be saturated with water upstream of the exchanger 5 which causes a drop in the temperature thereof and thereby increases its capacity to cool the incoming air (see arrow H 2 O in dotted lines) .
- Air from adiabatic compressor 1 can cool against other air gas flows apart impure nitrogen, in the exchange line.
