Abstract
Carbon dioxide and hydrogen sulphide are removed from gas mixtures, e.g. natural gas, synthesis gases, or water gas used in the production of hydrogen, by an aqueous solution of alkaline reagent, particularly alkali metal carbonates or phosphates, or mono-or diethanolamine, introduced at about atmospheric boiling temperature into the absorption zone maintained under superatmospheric pressure, some of the <PICT:0725000/III/1> gases being flashed off from the fouled solution in a regeneration zone maintained at a reduced pressure, the solution then being subjected to boiling and steam stripping to remove further quantities before return without substantial cooling to the absorption zone. Gases scrubbed in an absorber 2 under at least 50 lbs per sq. in. and preferably at least 100, escape through a condenser 30, fouled solution passing through a pressure let-down valve 8 to a flashing chamber 7 where the partly regenerated solution is led to the top of a stripping column 11 for countercurrent treatment with steam evolved from the boiling liquid heated by a steam coil 13 or introduced directly. Gaseous effluent leaves by a line 17 steam condensate being refluxed back to the column. Desorbed gas and steam from the flashing chamber is preferably admitted into the column at an intermediate level through a line 9. Regenerated solution is pumped back to the absorber preferably without any deliberate cooling or in any case by more than 20 DEG F. After the bulk of carbon dioxide &c. has been removed, residual quantities may be abstracted by a conventional second stage washing or in a modification, two stage absorption and regeneration are effected in the same apparatus by withdrawing the bulk of solution from the stripping column a little above the bottom and returning it to the absorber a little below the top. The relatively small quantity of more completely regenerated solution is introduced at the top of the absorber. Pressure reduction in the regeneration zone may be effected in stages, the final pressure preferably being atmospheric or 5-30 lbs. per sq. in. above. Both flashing and stripping operations may be carried out in the same vessel. Concentrated potassium carbonate solution is preferred as the absorbent as effecting a relatively large removal of carbon dioxide per pound of steam consumed, and in p examples 5-6 times as much carbon dioxide are removed per pound of steam by hot solution as by cold.
