Definitions
- Gaseous CO2 supply system for an installation requiring CO2 or a mixture containing CO2, such as a slaughterhouse or a plant growing greenhouse
- the present invention relates to processes and installations using gaseous CO2, particularly in the food industry.
- This CO2 mainly comes from fertilizer and methanol plants (by-product) or even hydrogen production plants.
- the availability of this molecule therefore becomes critical due to frequent shutdowns of fertilizer production plants and geopolitical tensions, which then have a strong impact on the price of gas.
- the present invention aims to propose an innovative solution for producing CO2 on the site of a user of this CO2.
- the present invention proposes to use the heat production equipment (boilers) traditionally present on such sites, by converting it or them to oxycombustion.
- the heat produced by the boilers will come from the production of CO2 and therefore considered “fatal heat” within the meaning of the legislation.
- Oxycombustion is a combustion process in which the oxidizing gas is no longer air but “pure” oxygen (i.e. characterized by a purity generally greater than 95%, and 99% for liquid oxygen) .
- Oxy-combustion i.e. with oxygen and not with air
- Oxy-combustion is already used by certain industries operating at high temperatures (glassworks, cement factories, metallurgy factories, etc.) because it provides a number of advantages including:
- the objective is in fact to increase the CO2 content of the combustion fumes by eliminating the nitrogen ballast, which then contains mainly CO2 and water.
- the purer the oxygen used for combustion the closer the combustion fumes are to a binary H2O/CO2 mixture.
- the main step in CO2 capture then consists of condensing the water.
- CO2 user sites also equipped with a boiler capable of supplying hot water to the site, this boiler, in particular condensation, using oxy-combustion between a fuel (CH4, C3H8, etc.). and pure oxygen, the oxygen supplying the boiler being obtained from a source of liquid oxygen present on site.
- a boiler capable of supplying hot water to the site, this boiler, in particular condensation, using oxy-combustion between a fuel (CH4, C3H8, etc.). and pure oxygen, the oxygen supplying the boiler being obtained from a source of liquid oxygen present on site.
- the “pure” CO2 thus obtained (recovered) in its gas or liquid form can be stored (sequestered) for later use on the site considered, or used “in just-in-time”, in “synchronized” flow with the need hot water and therefore the operation of the boiler.
- the heat exchanger used can be, for example, a plate exchanger, or even a tubular exchanger.
- the central heating water circuit is heated by the combustion of natural gas.
- the gas condensing boiler takes advantage of the energy contained in the combustion fumes.
- the fumes emitted during the combustion of natural gas contain water vapor, the latter condenses, releasing heat.
- the return water from the heating circuit is heated thanks to this energy, and the water released during condensation (condensate) is evacuated through the wastewater network.
- the need for CO2 is advantageously synchronized with the need for hot water, the drop in temperature obtained by the valorization of the frigories of liquid oxygen allows to purify the CO2 gas (at 20 bars and -20°C for example, only the CO2 will be liquid).
- greenhouse growers heat the greenhouse at night, therefore produce CO2 at night, while they require CO2 during the day for photosynthesis, it is therefore necessary to store the CO2 in a tank cryogenic.
- the present invention then relates to a process for supplying gaseous CO2 to a site comprising an installation requiring CO2 or a mixture comprising CO2, such as a slaughterhouse or even a plant cultivation greenhouse, characterized by the implementation implementation of the following measures: there is within said site a boiler capable of supplying hot water to the site, this boiler implementing oxy-combustion between a fuel and pure oxygen, the oxygen supplying the boiler being obtained from a source of liquid oxygen present on the site; we proceed to recover all or part of the CO2 contained in the fumes produced by the boiler, by organizing, in an exchanger, a thermal exchange between said fumes and the liquid oxygen.
- the present invention therefore also relates to a method and apparatus for the purification and liquefaction of CO2, on the user site, by efficientlyzing the frigories of the liquid oxygen present on the site.
- This CO2 liquefaction can be preceded by one or more smoke treatments by physical and/or chemical separation methods, but also cryogenic, aimed at: heating the oxygen and the combustible gas, to improve combustion and reduce emissions.
- nitrogen oxides condense the water vapor from the fumes and perfectly recover the heat of condensation or latent energy (by lowering the temperature of the fumes the water vapor is transformed into liquid water). remove any dust generated by the boiler hearth (refractory dust).
- Oxy-Combustion with methane requires 64g of oxygen for 16g of CH4 and will produce 36g of water which will be easily separated and 44g of CO2.
- CO2 requires approximately 85 Kcal/kg to go from +20°C to -20°C (20 bar).
- Liquid oxygen releases 71.7 Kcal/kg at 8 bars from its liquid form at a temperature of -30°C.
- the theoretical cooling capacity available is therefore (71.7 x 1.45) + 103 Kcal to liquefy one kg of CO2.
- Figure 1 illustrates an example of equipment suitable for implementing the invention, in the case of use on the site considered to perform anesthesia on poultry in a tunnel.
- hot water is used to pluck the poultry and gaseous CO2 is used to put the poultry to sleep. In this case it was not necessary to liquefy the CO2.
- this exchanger 2 carries out the heat exchange between the fumes and the liquid oxygen, the temperature of the fumes is lowered to a temperature typically close to 2°C to remove as much water as possible, and then keep CO2.
- regulation valve (which is controlled by the anesthesia tunnel, if the tunnel is stopped the gases are sent outside, while the more CO2 the tunnel requires, the more the valve opens towards the circuit of the tunnel).
- CH4 heater this heater allows the combustible gas to be heated before sending it to the burner.
- O2 heater this heater allows the oxygen to be heated before sending it to the burner.
- At boiler 4 town water enters at a temperature close to 25°C and leaves at a temperature close to 85°C, the fumes leave the boiler at a temperature close to 220°C.
- the combustible gas enters at a temperature close to 15°C and leaves at a temperature close to 95°C, and the fumes exit this element 10 at a temperature close to 210°C.
- the oxygen enters at a temperature close to 5°C and leaves at a temperature close to 95°C, and the fumes leave this element 11 at a temperature close to 200°C.
- the city water enters at a temperature close to 5°C and leaves at a temperature close to 25°C, and the fumes leave this element 12 at a temperature close to 90°C (The exchanger 12 therefore makes it possible to recover calories in the fumes and preheats the water which will enter the boiler (principle of condensing boilers)).
- the oxygen enters at a temperature close to -183°C and leaves at a temperature close to +5°C, and the fumes leave this element 2 at a temperature close to +2 °C.
- the water is completely condensed, only CO2 remains.
- the tap water enters at a temperature close to 15°C and leaves at a temperature close to 5°C, and the fumes leave this element 7 at a temperature close to 10 °C (exchanger 7 therefore makes it possible to raise the temperature of the CO2 to around 10-12°C after removing the water, which is required for such anesthesia applications according to current legislation).
- the mass of CO2 released per mole of octane consumed is 44 g.
- the exchanger 2 to carry out such liquefaction can also be a cryo-condenser, which is a heat exchanger operating at low temperature, the gaseous effluent from the industrial process penetrates inside a calender, then travels through a series of baffles, around a finned tubular bundle in which a liquid cryogen circulates.
- a cryo-condenser which is a heat exchanger operating at low temperature
- CO2 is a gas which changes state into a solid phase at a pressure close to 4.7 bar, so we must avoid getting close to this pressure.
- a pressure between 16 bar and 20 bar is economically favorable, while a temperature of -20°C requires little investment in terms of insulation.
