Definitions

  • This invention relates generally to the field of purification of gases.
  • Our immediate interest is in the removal of vapors, such as water or carbon dioxide, that would be considered an impurity from a gas stream, such as combustion flue gas, natural gas, syngas, and air.
  • Chemical complexing in solids occurs by passing the gas stream through a bed of desiccants or related solids that chemically bind the vapor. Chemical complexing in liquids occurs in brine solutions, near-eutectic solutions, or other systems where the liquid has the ability to complex with the vapor.
  • Condensation occurs when the partial pressure of the vapor is reduced below the vapor's condensation point, allowing the vapor to condense into a liquid form.
  • Desublimation is considered a form of condensation, as it brings a gas to a condensed state, namely to a solid.
  • United States patent publication number 2008/7314502 to Kelley teaches a method for the separation of a single component from a multi -component gas stream. This disclosure is pertinent and could benefit from vapor removal methods disclosed herein and is hereby incorporated for reference in its entirety for all that it teaches.

  • the liquid mixture is then reconstituted after passing through the separation chamber by a chemical separation process chosen to remove an equivalent amount of the carbon dioxide vapor from the liquid mixture as was removed from the carrier gas.
  • the reconstituted liquid mixture is restored to temperature and pressure through heat exchange, compression, and expansion, as necessary, in preparation for recycling back to the separation chamber.
  • the liquid mixture is then returned to the separation chamber. In this manner, the carrier gas leaving the exchanger has between 1% and 100% of the carbon dioxide vapor removed.

Abstract

L'invention concerne un procédé pour l'élimination continue d'une vapeur, qui serait considérée comme une impureté, d'un gaz vecteur. De préférence, la vapeur est soit de la vapeur d'eau soit de la vapeur de dioxyde de carbone. Le présent procédé inclut, en premier lieu, le fait d'amener un contact direct du gaz vecteur avec un mélange liquide dans une chambre de séparation, le gaz vecteur se condensant à une plus basse température que la vapeur. Une combinaison d'effets chimiques amène la vapeur à se condenser, à complexer, ou à la fois à se condenser et à complexer avec le mélange liquide.
