Definitions
- STEP Pumped Water Transfer Station
- batteries of different types lithium, nickel, sodium-sulfur, lead-acid .
- FES Flywheel Energy Storage
- compressed air energy storage technology using compressed gas, (often compressed air) is promising.
- the energy produced and not consumed is used to compress air at pressures between 40 bar and 200 bar using compressors (which can be multi-stage).
- compressors which can be multi-stage.
- the air temperature increases.
- the air can be cooled between each compression stage.
- the compressed air is then stored under pressure, either in natural cavities (caverns) or in artificial reservoirs.
- the stored air is then sent to turbines to produce electricity.
- the air cools.
- the air can be warmed up before relaxation.
- SUBSTITUTE SHEET (RULE 26) years ago, such as the Huntorf unit in Germany operating since 1978 or the Macintosh unit in the USA (Alabama) operating since 1991. These two installations have the particularity of using stored compressed air to supply gas turbines. These gas turbines burn natural gas in the presence of pressurized air to generate very hot (550 ° C and 825 ° C) and high-pressure (40 bar and 1 1 bar) combustion gases before they are vented. turbines generating electricity. This type of process emits carbon dioxide. The Huntorf unit could emit approximately 830 kg of C0 2 per megawatt of electricity produced.
- the air is often air taken from the surrounding environment. It can therefore contain water in the form of steam. This humidity varies according to the geographical location and the temperature and / or the season.
- This condensation can represent significant quantities to manage. For example, in Nice (France), in January, air contains about 4 grams of water per kilogram of air. In August, this amount of water drops to 12 grams of water per kilogram of air at the suction of the compressors. Few patents cite this problem of water management.
- Certain patents (WO 2016/012764, WO 201 1/076926 and WO2016 / 079485) propose to recover the condensation water to store it in a simple storage tank. Moreover, when it is not taken from gas, the water contained in the gas can cause deterioration of compressors and other equipment, in which the compressed gas circulates.
- heat exchangers are used. These exchangers make it possible to cool a hot gas, from a cold fluid (often a cold liquid), or to heat a cold gas, from a hot fluid (often a hot liquid).
- direct contact heat exchangers refers to heat exchangers in which there is direct contact between a (often liquid) fluid and a gas. When direct contact heat exchangers are used, material exchanges between the fluid and the gas can also occur.
- the gas may be partially charged with fluid in the form of gases or liquid droplets and / or a portion of the gas may condense or be absorbed by the fluid. It depends on the fluid, the gases, pressures and temperatures as well as the mode of exchange (heating or cooling the gas). It may therefore be necessary to add fluid in the circuit or on the contrary to extract it, making the management and regulation of these flows more complex. Without management of these flows, system performance is reduced and the risk of damage to system components is increased.
- Heat exchangers in which there is no direct contact between the fluid and the gas are called "heat exchangers without direct contact".
- heat exchangers without direct contact the heat exchange is done for example through a solid wall but no transfer of material can be done between the fluid and the gas.

- separation means are used, preferably at least one separation means after each of said first heat exchangers.
- a plurality of second heat exchangers are used, preferably at least one second heat exchanger upstream of each of said expansion means.
- said means for introducing the liquid leaving the separation means comprises an intermediate storage tank.
- the invention also relates to a method for storing and recovering energy in which the following steps are carried out:
- step e) heating said compressed compressed gas by a heat exchanger using the hot liquid stored in step c) and storing said cold liquid;
- step c) The condensed liquid stored in step c) is injected into said stored cold liquid.
- step e) and f) is performed several times before performing step g).

- V-101 of the liquid and the gas makes it possible to separate the air (stream 4) from the condensed liquid.
- This condensed water then joins an intermediate storage means of the condensed liquid T-301.
- the air then enters a second compression stage K-102 where it leaves at a higher pressure and temperature (stream 5). It is then cooled in a heat exchanger without direct contact E-102 with cold water (stream 31).
- the hot water leaving the exchanger E-102 (stream 58) is sent to a hot liquid storage means T-404.
- the cooled air (stream 6) enters a gas-liquid separator V-102 separating the condensed moisture (stream 24) from the cold air (stream 7).
- the condensed moisture is sent to the condensed liquid intermediate storage means T-301.
- the cooled air (stream 7) enters a third compression stage K-103 from which it emerges (stream 8) at a higher pressure and at a higher temperature. It is then cooled in a non-direct contact heat exchanger E-103 with cold water (stream 33). The water emerging from the exchanger E-103 (stream 59) is then sent to a hot liquid storage means T-403.
- the cold air meanwhile, enters a gas-liquid separator V-103 where the condensed moisture (stream 25) is separated from the air (stream 10). This condensed moisture is then sent to the condensed liquid storage means T-301.
- the cold air (flow 10) leaving the separator V-103 then enters a last compression stage K-104, from which it emerges (flow 1 1) at a higher pressure and temperature. It is then cooled in a non-direct contact heat exchanger E-104 with cold water (flow 36). This stream 36 can be cooled, by means of an E-105 heat exchanger, at a lower temperature than that of the water used for the exchangers E-101, E-102 and E-103.
- the hot water (stream 37) leaving the heat exchanger E-104 is then sent to a hot liquid storage means T-405.
- the cold air (stream 12) enters a gas-liquid separator V-104 where the condensed moisture (stream 26) is sent to the condensed liquid storage means T-301.
- the cold air (stream 13), 50 000 kg / h, exiting at a pressure of 136.15 bar and at a temperature of 30 ° C is sent to a compressed gas storage means T-201 which can be either natural or artificial. It contains only 300 ppm of water.
- the power consumption for the compression stage is equal to 10.9 MW.
- the cooling of the air during the compression uses 54,689 kg / h of cooling water and the condensation of the humidity of the air represents a quantity of 1, 35 ton / hour that must be stored or eliminated.
- the stored air (stream 14) is sent from the compressed gas storage means T-201 to a direct-contact heat exchanger C-205 with hot water (stream 60) or from hot liquid storage means T-402.
- the cooled water (stream 40), leaving the bottom of the heat exchanger C-205, is sent to a cold liquid storage means T-406.
- the cooled water (stream 42) leaving the bottom of the heat exchanger C-206 is sent to the cold liquid storage means T-406.
- the heated air (stream 19) is sent to an EX-203 turbine where it is expanded to a lower pressure (stream 20).
- This cold air is warmed by hot water (stream 63) from the hot liquid storage means T-405 in the C-208 direct contact heat exchanger.
- This cooled water (stream 43) is sent into the cold liquid storage means T-406.
- the air, 52 240 kg / h, after final expansion is released into the atmosphere (stream 50) at a pressure of 1.02 bar and a temperature of 39 ° C.
- the water that has been used for the various air warmings through the heat exchangers C-205, C-206, C-207 and C-208 and stored in the cold liquid storage means T-406 is at a temperature of 93.3 ° C final.
- this water Before being recycled, this water needs to be cooled, for example by a water exchanger or by an air cooler.
- the cooling power required is 3.3 MW thermal, which is an electric power consumption of 31.6 kW electric.
- the electric power produced by the successive detents is equal to 5.6 MW electric.
- the amount leaving the process after expansion of the air is 53,792 kg / h less than the amount of water required for cooling.
- the process consumes water.
- This stream 2 is then cooled to 50 ° C in a heat exchanger E-101 without direct contact (stream 3) with water at 40 ° C (stream 29).
- the air then enters a second compression stage K-102 where it leaves at a higher pressure and temperature (stream 5). It is then cooled in a heat exchanger without direct contact E-102 with cold water (stream 31).
- the hot water leaving the exchanger E-102 (stream 32) is sent to a hot liquid storage means T-403.
- the cooled air (stream 6) enters a gas-liquid separator V-102 separating the condensed moisture (stream 24) from the cold air (stream 7).
- the condensed moisture is sent to the condensed liquid storage means T-301.
- the cooled air (stream 7) enters a third compression stage K-103 from which it emerges (stream 8) at a higher pressure and at a higher temperature.
