Abstract

In a process for removing CO2 from gas mixtures, e.g synthetic fuel gas, by the continuous circulation of an aqueous solution of K2CO3 at a temperature near its atmospheric boiling temperature between an absorber operated at super-atmospheric pressure, preferably over 100 lb. per square inch, and a steam stripper, operated at atmospheric pressure, e.g. as described in Specification 725,000, an ethanolamine is added to the solution, e.g. in amounts of from 0.3% to 10%, preferably 1% to 6%, by weight of the solution. The operating conditions of the process (residence time of the gas in the absorber, degree of regeneration and circulation rate of the solution) should be such as to ensure a partial pressure of CO2 at the outlet of the absorber of less than 1.5 lb. per square inch, to achieve the maximum efficiency (see Fig. 2, not shown). The process effects a saving in the amount of steam needed in the stripping zone. A minor amount of the solution may be more completely regenerated than the rest, or a minor amount of the regenerated solution may be cooled by 20 DEG to 40 DEG C., these minor amounts being returned the top of the absorber and the rest of the solution to an intermediate point in the absorber. Comparative examples are described.ALSO:Carbon dioxide is removed from gas mixtures by a method similar to that described in Specification 725,000 in which a hot aqueous solution of K2CO3 is continuously circulated between an absorber operated at superatmospheric pressure and a steam stripper operated at atmospheric pressure. The solution contains ethanolamine in amounts of from 0.3 to 10% by weight of the solution, and the operating conditions of the process (gas residence time in the absorber, degree of regeneration and circulation rate of the solution) should be such as to ensure a partial pressure of CO2 at the outlet of the absorber of less than 1.5 lbs. per square inch. A minor amount of the solution may be more completely regenerated than the rest, or a minor amount of regenerated solution may be cooled by 20 DEG to 40 DEG C., these minor amounts being returned to the top of the absorber and the rest to an intermediate point in the absorber.
