can be regenerated using methods known in the art in view of the present disclosure alternatively after the mixing and contacting the gas stream containing the gas mixture and the vaporized and or vaporizing amine remains in the same chamber but the temperature of the chamber is lowered to allow the reaction products to separate out from the gas stream by condensation and or solidification a gas mixture contacts and mixes with a compound or solution of compound such as an amine from a pure amine or an amine solution in a pressurized chamber the mixture of the gas and a pure amine or an amine solution is then injected into a second chamber having a lower pressure the sudden reduction in the pressure vaporizes the amine and decreases the temperature of the mixture of the gas and amine and the reaction products of the amine and one or more acid gases such as co2 in the gas mixture are then separated out from the gas stream by condensation and or solidification the liquid and or solid form of the reaction products are separated by conventional means in view of the present disclosure the remaining gas mixture is thus deacidized the reaction products of amine and co 2 in the form of liquid and or solid can be regenerated using methods known in the art in view of the present disclosure the lower pressure chamber can be a simple empty container such as a container with cooling system it can also be a cyclone a cyclone with a cooling system and or any other device known to those skilled in the art in view of the present disclosure alternatively after the mixing and contacting the mixture of the gas and absorbent remains in the same chamber but the.
