Definitions
- the present invention relates in general to a method and apparatus to improve and optimize the product of air separation gases (oxygen, nitrogen, and/or argon) by a compressed air energy storage system and an air separation process.
- air separation gases oxygen, nitrogen, and/or argon
- cryogenic separation the compressed air is passed through a cold box heat exchanger to recover refrigeration from product gases and then is introduced into a two stage distillation process (high pressure and low pressure) to cause the components of air to separate due to their varying volatility.
- oxygen gas is required as moderate to high pressures (400 to 600 psi)
- the manufacturing cycles that are used to perform the air separation employ incoming air at a pressure or 1.2 to 1.5 times the product pressure.
- cryogenic cycles to produce nitrogen at pressure that may also use elevated air pressure. In all events the lowest pressure for make up air that is employed is above 100 psi.
- Membrane, vacuum swing adsorption, or pressure swing adsorption air separation processes require compressed air above a pressure of 50 psi to be passed through the air separation unit. These units do not require heat exchange as the separation is not performed at reduced temperature as is the case with cryogenic separation.
- the cost of producing oxygen, nitrogen and argon is split between the cost of power and the amortization of the capital needed for the plant. Labor, maintenance, cooling water, lubricants and consumables, insurance, property taxes make up the remaining costs which are small by comparison.
- a typical oxygen plant producing gas oxygen in tonnage quantities at 600 psi might require 450 KWh per ton to produce 99.5% pure oxygen. Nitrogen plants will require 225 KWh per ton to produce 99.9% pure nitrogen at 200 psi.
- the present invention relates in general to a method and apparatus to optimize the production of air separation gases (oxygen, nitrogen and/or argon) with a compressed air energy storage system having an air separation system.
- air separation gases oxygen, nitrogen and/or argon
- the manufacture of oxygen, nitrogen and argon via air separation through cryogenic, pressure swing adsorption, or membrane separation is a well established enterprise.
- the technology that is mostly employed is that of cryogenic separation as this is the most economical method for large scale (tonnage) oxygen, nitrogen and argon manufacture. All of above methods require compressed air as the source of the manufactured gas.
- the typical cryogenic air separation process has to have a continuous stream of compressed air flowing into the separation unit as the unit operates at reduced temperature and cannot be run in an on/off mode.
- Membrane and pressure swing adsorption units also require continuous air flow to produce air separation gases on a continuous basis. Therefore, manufacturers of air separation gases run these units on a continuous basis.
- the compression of the air stream requires significant amounts of energy as air is compressed from ambient condition to pressures that range from 80 psi to 1000 psi. Electric power is the most common form of purchased energy to power the air compression in an air separation plant. Standard air separation plants, therefore, purchase electricity during all periods of the day and night and the power purchased is charged at rates that cover peak, semi-peak and off peak periods.
- An embodiment of this invention allows the manufacture of such air separation gases to be performed with electric power purchased during off- peak or semi-peak periods when it the unit cost of electric power is much less expensive.
- the facility is a combination of a compressed air energy storage system and the air separation unit.
- Compressed air energy storage units compress air during periods of off-peak or semi-peak electric power costs. This compressed air is stored in above surface vessels, subterranean caverns or aquifers.
- the air compression system for the air separation unit is shared with the compressed air energy storage unit and economies of scale are, therefore, gained. During periods of off-peak or semi-peak power costs, air is compressed by these air compressors and is introduced into the storage system.
- a side stream of air from the air compressors is also directly and continuously passed through the air separation unit.
- the air compressors are turned off and air is extracted from the storage system and is flowed through the air separation system and/or a turbine expander that produces electricity for resale at a higher price.
- the air separation unit therefore has a uninterrupted flow of air, and an uninterrupted supply of low cost energy, and can produce air separation gases continuously.
- the reduction in the unit price paid for electric energy is significant and as the predominant operating cost to produce air separation gases is electric power, the gases are produced at a significantly lower cost than in the standard air separation process.
- an object of the invention is an apparatus and method for producing air separation gases of oxygen, nitrogen and/or argon with a compressed air energy system having an air separation plant.
- Another object of the invention is an apparatus and method for manufacturing air separation gases as by compressing denser air, thereby requiring less energy.
- Another object of the invention is an apparatus and method for manufacturing air separation gases as air is compressed during off-peak and semi-peak periods, thereby requiring less energy at a reduced cost rate.
- a further object of the invention is an apparatus and method for manufacturing air separation gases at a wider range of production rates as the method and apparatus are not limited by the "turn down" characteristics of the air compression system in a typical air separation plant.
- FIG. 1 is a schematic flow chart of the process and apparatus for a compressed air energy storage with an air separation unit for making component gases of oxygen, nitrogen, and or argon.
- the present invention is based on a compressed air energy storage system with an air separation process, such as for example a cryogenic air separation unit, resulting in the optimized manufacture of the air separation gases of oxygen, nitrogen and or argon.
- compressed air energy storage systems can be found in the following: (1 ) Importance of Adequate Geotechnical Evaluation for CAES Siting in Aquifers, by Cole R. McClure and John H.
- electric power 7 is fed into the motor of the compressed air energy storage plant 2 to suck ambient air 1 into the compressor section of the compressed air energy storage plant 2.
- This air 1 is compressed such that compressed air 16 leaves the compressed air energy storage plant 2 at a pressure between 50 and 1500 psia.
- This compressed air 16 then is split into two streams.
- Stream 11 is fed into the air separation plant, and stream 17 is sent to the above or below ground air storage system 3.
- the quantity of air flowing in stream 11 is controlled by the flow control valve 8.
- the compressed air in stream 17 is constantly added to the quantity of air stored under pressure in the storage system 3.
- the air in stream 11 is fed to the air separation unit 13 to produce air separation gases of oxygen, nitrogen and or argon in gas or liquid form 14 .
- the compressed air energy storage plant 2 no longer draws electric power 7 to its motor. Instead compressed air 4 is extracted for the air storage system 3 and is split into two streams of compressed air 5 and 12.
- Stream 5 is routed to the turbine expander section of the compressed air energy storage plant where it is expanded in the presence of natural gas or a liquid fuel 15 to produce power 6 which is dispatched and sold to the electric power grid. This power can be used to run the air separation unit.
- the quantity of compressed air in stream 12 is controlled by flow control valve 9. This stream of compressed air 12 replaces the air in stream 11 to feed the air separation plant 13 to produce air separation gases 14.
- Control valve 9 can be set to regulate the flow of air 12 over a wide range from 5% to 100% of the rated capacity of the air separation plant 13. This range is larger than the range of operation of a standard air separation plant given the limited performance characteristics of a compressor used in the standard air separation plant.
- Unit 20 includes a set of automatic controls that can be run by a computer to perform the method of the invention.
- Such control 20 can be programmed to turn on and of the various values and regulate flow of compressed air and air separation products.
- Further controls can be programmed to take into consider any or all of the following as well as other factors: air temperature, time of day, humidity, gas output requirement of the air separator units, and power rate costs. Economics of an Embodiment of the Invention:
- An embodiment of the invention includes a compressed air energy storage system and an air separation system which allows manufacturers of air separation gases to essentially purchase their entire electric power requirements at the cost of off-peak or semi-peak period and avoid the cost of purchasing power during peak periods when power is the most costly.
- the present invention has significant utility in the production of air separation gases from a compressed air storage system with an air separation process.
