Definitions

- This device implements a decarbonation reaction of the biogas by neutralization in the liquid phase by lime Ca (OH) 2.
- This device is simple in design and can be easily operated by a biogas producer.
- the chemical principle of decarbonation in the liquid phase by lime is a reliable and efficient solution. This principle also allows for a cost-effective solution for both investment and operating costs. Indeed, the proposed technique uses only one basic reagent, lime Ca (OH) 2 whose purchase cost in industrial quantities is about one hundred euros per ton. In addition, in terms of safety, the device has no hot spot.
- the device also has the advantage of trapping all the CO2 in the form of solid and stabilized calcium carbonate (CaCC).
- CaCC solid and stabilized calcium carbonate
- This inert material presents no health risk and can be efficiently conserved locally in agricultural composting with lime incineration to stabilize the pH of acidic soils for example, or to bring to the soil a additional source of calcium and inorganic carbon.
- Residual calcium carbonate can also be used in local construction as backfill or in the form of lime plaster.
- liquid recirculation and pH regulation allow the device to be automatically regulated without human intervention.
- the device which is the subject of the present invention comprises an intermediate vessel, in the path of the liquid, downstream of the first vessel and upstream of the second vessel, for retaining a liquid volume comprising lime and water.
- water comprising:
- the first vessel has a decarbonated biogas outlet.
- At least one decarbonated biogas outlet has a biogas shunt connected to a biogas inlet of at least one vessel.
- At least one decarbonated biogas outlet comprises means for measuring a quantity of carbon dioxide in the biogas leaving the tank associated with said outlet, the biogas supply of the bypass associated with said outlet being controlled according to the amount of carbon dioxide measured.
- the biogas inlet is configured to inject the biogas into the first vessel at a rate of between five and sixty meters per second.
- the liquid is lime water. These embodiments allow the liquid to exhibit no solid particles.
- the liquid is lime milk.
- the maximum retention volume of the first tank is determined by an overflow wall having a predetermined height, the overflow of the liquid being effected to the second tank.
- the first and / or second vessel comprises calcium carbonate collection means positioned on a lower portion of said vessel.
- the first vessel comprises:
- the second portion comprising:
- the device that is the subject of the present invention comprises: an additional inlet for the liquid positioned on a lower part of the first part of the first tank,
- the device which is the subject of the present invention comprises a means for preventing scaling comprising:
- a control means for injecting water and biogas into the first tank a control means for injecting water and biogas into the first tank.
- the present invention aims at a process for decarbonating biogas, which comprises:
- a liquid entry step in a first portion of a first tank a step of entering biogas into the liquid in the first portion of the first tank
- FIG. 1 represents, schematically, a first particular embodiment of the device that is the subject of the present invention
- FIG. 2 represents, schematically, a second particular embodiment of the device that is the subject of the present invention
- FIG. 3 represents, schematically and in the form of a logic diagram, a particular succession of steps of the method that is the subject of the present invention
- FIG. 4 schematically represents a third particular embodiment of the device that is the subject of the present invention.
- the biogas described below can be of type:
- FIG. 1 which is not to scale, shows a schematic view of an embodiment of the device 10 which is the subject of the present invention.
- This device 10 for decarbonating biogas comprises:
- an outlet 120 for the liquid configured to release a portion of the liquid when the volume of liquid in the first tank 105 is greater than a predetermined maximum retention volume
- a second tank 125 for retaining a liquid volume comprising lime and water, comprising:
- the liquid used by the device 10 is, for example, milk of lime.
- the milk of lime is a water supersaturated in lime presenting solid particles.
- the lime provided by the means 155 for supplying lime is:
- the device 10 comprises a means for preparing lime water and / or milk of lime configured to supply the means 155 for supplying lime.
- This means of preparation is for example a water mixture tank and solid lime, the amount of solid lime inserted into the tank as a function of the pH of the captured liquid.
- the liquid is lime water.
- the lime water is saturated with lime at the threshold of solubility of Ca (OH) 2 and therefore has no solid particle.
- Lime water is the supernatant obtained after saturation and decantation of the milk of lime.
- the first tank 105 is, for example, a closed and sealed volume configured to retain a predetermined volume of liquid.
- This first tank 105 is formed, in FIG. 1, of a base and side walls surrounding the base so as to define the volume of the tank 105.
- the first tank 105 acts as a decarbonation compartment of the biogas by neutralization of the CO2 in aqueous phase.
- the decarbonation is carried out by contacting the biogas with a water saturated with lime or a milk of lime.
- the carbon dioxide contained in the biogas changes from the gaseous phase to the basic aqueous phase by a conventional transfer mechanism.
- the hydroxide ions (OH-) provided by the lime make it possible to neutralize the dissolved CO2 by forming the hydrogen carbonate and bicarbonate ions in solution.
- the chemical reactions involved in the solubilization of CO2 and its neutralization are represented by the following acid-base equilibria:
- This neutralization with lime also has the effect of eliminating to a certain extent the hydrogen sulphide present in the biogas.
- the sulfur precipitates are therefore likely to form, thus making it possible to eliminate all or part of the traces of H2S gas present in the biogas.
- the device 10 constitutes a reactor for the chemical mechanisms described above. This device 10 makes it possible to bring the biogas into contact with the solution of water saturated with lime. After this contact phase, a purified biogas is obtained and a water settling phase makes it possible to recover the solid particles of calcium carbonate and lime incinerators at the bottom of the device 10.
- the inlet 1 10 for liquid is, for example, a sealed pipe connected to a liquid injection valve in the first tank 105.
- This liquid inlet 1 10 is preferably positioned on a lower part of a wall, c ' that is to say close to the lower part of the first tank 105.
- the liquid entering the first tank 105 fills the first tank 105 until the predetermined maximum retention volume is reached by the volume of liquid in the first tank 105.
- the inlet 15 for biogas is, for example, formed of several hollow injection columns provided with orifices for injecting biogas into the liquid when the liquid fills the first tank 105.
- the biogas inlet 15 is configured to inject the biogas into the first tank 105 at a rate of between five and sixty meters per second.
