Definitions

  • the present disclosure relates to a method and apparatus for capture of carbon dioxide (C0 2 ).
  • C0 2 carbon dioxide
  • capture of C0 2 from combustion gases such as flue gases.
  • US 7727374 discloses a system using a sodium hydroxide ion solution to capture carbon dioxide, which reacts with the sodium hydroxide to form sodium bicarbonate in solution.
  • This sodium hydroxide ion solution is produced by electrolysis, along with the addition of acid.
  • the sodium bicarbonate is extracted from the water using heated precipitation. This process is energy intensive and the electrolysis process produces potentially hazardous waste products in the form of chlorine gas and also hydrogen gas.
  • the disclosure provides a method of treatment of combustion gases for carbon dioxide capture comprising: (i) providing a solution of sodium bicarbonate and sodium carbonate in water; (ii) contacting the solution with a gas mixture, the gas mixture including carbon dioxide, such that carbon dioxide dissolves in water and reacts with hydroxide ions in the solution to form bicarbonate ions; (iii) continuing step (ii) until sodium bicarbonate precipitates out of the solution as a solid; (iv) removing the solid sodium bicarbonate; and (v) heating the sodium bicarbonate to form sodium carbonate, water and carbon dioxide; wherein during steps (i) to (iv) the sodium bicarbonate concentration in the solution is maintained at 80% or more of saturation levels.
  • solubility of sodium bicarbonate in water which is 96 g/l at 20 °C
  • solubility of sodium carbonate in water which is 215 g/l at 20 °C.
  • This difference in solubility means that, with an appropriate amount of sodium carbonate in solution, solid sodium bicarbonate will result when sufficient carbon dioxide is added to the solution.
  • One mole of dissolved carbon dioxide reacting with this sodium carbonate / sodium bicarbonate solution will result in precipitation of two moles of sodium bicarbonate.
  • One mole of sodium carbonate needs to be added to renew the solution.
  • the sodium carbonate may be obtained from the calcination of the two moles of precipitated sodium bicarbonate, resulting in a closed loop of involved chemicals for the preferred embodiments of the invention.
  • a significant advantage with the proposed method is the effective mixing of gas and liquid to facilitate the absorption of C0 2 in the liquid. If solid bed or scrubbers are used, as in some prior art techniques, the relative slow reaction rate of the C0 2 reaction with the OH " ions results in large and expensive size equipment and low capture rates. In the proposed method, a long residence time and a high reactant volume compensate the slow reaction. In preferred embodiments the method may advantageously make use of a new contactor where gas is introduced via a mixer- injector that creates large numbers of small bubbles of gas in the solution. An advantage of such a contactor is the ability to work with precipitating systems, where scrubbers have a problem.
  • the introduction of the bubbles in the absorbent is done with an aspirating turbine, also known as an aerator, one type being manufactured by Heinrich Frings GmbH & Co. KG under the trademark "Friborator”, through a manifold where combustion gas is fed into the manifold and ejected into the absorbent as bubbles or by using ultrasonic devices and the like.
  • an aspirating turbine also known as an aerator, one type being manufactured by Heinrich Frings GmbH & Co. KG under the trademark "Friborator”
  • combustion gas is introduced in this way will revitalize processes with slow reaction kinetics, such as: carbonate processes, slow amines and amino acid methods.
  • the reaction forms solids that precipitate from the liquid. This enables the process only to treat the solids and not the reactant liquid.
  • the reactant is preferably recycled as discussed further below.
  • the recycling process involves shifting the reactant between phases from liquid to solid and back to liquid. As noted above, carrying out the reaction in solution makes the whole mass available for reaction and not only the surface. Soiling of surfaces is not a problem since the solids are dissolved and reformed and pollutants in the system will not stick to the surfaces.
  • Other gasses and particles in the gas may be absorbed by the liquid: NO x , metals and particles will to some extent form solids that will precipitate, but will not be re- dissolved in the carbonate resolver and can therefore be separated from the reactant.
  • Sodium bicarbonate is safe and easy to handle. It can be easily transported or stored. The calcination process can therefore be centralized for small sources e.g. capture on ships with calcination in harbours.
  • the calcination is done by: (v) heating the sodium bicarbonate to form sodium carbonate, water (generally as water vapour) and carbon dioxide.
  • the carbon dioxide may be captured for storage, sequestration or used as an ingredient in industrial processes such as methanol production.
  • the method includes: (vi) capturing and, optionally, drying the carbon dioxide and (vii) recycling the sodium carbonate into the sodium carbonate solution used in (i).
  • the water can also optionally be recycled.
  • This sequence of steps creates a closed or partially closed loop for the sodium carbonate required in the process, which is hence not consumed but instead can be continuously recycled to a full or partial extent.
  • the method does not require any addition of sodium compounds, such as sodium carbonate or sodium hydroxide to maintain the working solution.
  • the process does not include the addition of such sodium compounds.
  • the only necessary inputs to the process when it is in steady state are the combustion gases and the heat (or energy) required for thermal decomposition of the sodium bicarbonate.
  • the heat required can be minimised by recovering heat from the system after the reaction, although of course there will always be some losses so some extra heat input is always required.
  • this extra heat can be obtained from the combustion gases.
  • the sodium carbonate solution can be regenerated by the recycled sodium carbonate.
  • the water can advantageously also be re-used in the sodium carbonate solution, and although this is a lesser advantage since water is more abundant than sodium carbonate it is nonetheless a useful feature, especially when pure water is not readily available, for example on board a ship. This provides considerable additional advantages compared to the process proposed in US 7727374, which involves the use of a solution with sodium hydroxide solution to capture carbon dioxide, but involves continued consumption of raw materials and energy, rather than allowing for an efficient recycling system.
  • the sodium bicarbonate may be treated in a drier to remove excess moisture.
  • the water removed from the sodium bicarbonate may optionally be recovered and recycled into the sodium carbonate solution.
  • the carbon dioxide may be treated in a drier to recover water before the carbon dioxide is processed further.
  • the water thus obtained may optionally be recovered and recycled into the sodium carbonate solution.
  • the heating at step (v) may be at a temperature of 70 °C to 250 °C.

  • the concentration may be at about fully saturated for sodium bicarbonate.
  • the process is most effective when the concentration is as close to saturation as possible.
  • Sodium carbonate is preferably continually added to the solution (either as a solid or as a solution) as the reaction with carbon dioxide precipitates out sodium bicarbonate and 'removes' reactants from the solution. In preferred embodiments, this sodium carbonate is recycled from the sodium carbonate produced by the heating in step (v). It will be understood that the solubility of sodium carbonate (and sodium bicarbonate) will vary with temperature.

L'invention concerne un procédé de traitement de gaz d'échappement pour une capture de dioxyde de carbone, qui consiste à mettre en contact un mélange de gaz de combustion comprenant du dioxyde de carbone avec une solution de bicarbonate de sodium et de carbonate de sodium dans l'eau, de telle sorte que le dioxyde de carbone réagit avec des ions hydroxydes dans la solution pour former des ions de bicarbonate ; poursuivre la mise en contact jusqu'à ce que le bicarbonate de sodium précipite à partir de la solution sous forme solide ; retirer le bicarbonate de sodium solide ; et (v) chauffer le bicarbonate de sodium pour former du carbonate de sodium, de l'eau et du dioxyde de carbone ; pendant les étapes (i) à (iv), la concentration de bicarbonate de sodium dans la solution étant maintenue à 90 % ou plus des niveaux de saturation. Avantageusement, le procédé peut être réalisé dans une boucle de recyclage en continu dans laquelle le bicarbonate de sodium est fractionné par la chaleur en carbonate de sodium, eau et dioxyde de carbone, et le carbonate de sodium est recyclé dans la solution. Le dioxyde de carbone peut être comprimé et stocké.
