Title: Method of removing gases easily soluble in water from hydrogen-containing gas mixtures
IPC: C10K1/10
Filed: 1961-04-05
Abstract: <PICT:0924190/III/1> A method of freeing a gas mixture containing hydrogen and, optionally, other slightly soluble gases, e.g. CO, of readily soluble gases e.g. CO2, SO2 and H2S, comprises extracting the readily soluble gases from the mixture with water under pressure and then wholly or partially expelling from the water the hydrogen and any other slightly soluble gases present in the said mixture by contacting the water with nitrogen.  The contacting with nitrogen may be under pressure.  The readily soluble gases are liberated from the water by pressure release or by pressure release followed by aeration.  As shown, the raw gas mixture is admitted to absorption column through pipe 8 at a pressure of 10-35 atmospheres and ascends through the packing 2 p  counter-current to regenerated water admitted at the top of the column through pipe 11.  The CO2 content is almost completely, and any H2S completely, absorbed by the water which takes up a further part of H2 and CO.  During the further passage of the water through the packing 3 counter-current to the ascending N2 admitted at 10 almost all H2 and CO absorbed by the water is expelled.  The water under pressure passes to the turbine 13 where a pressure release takes place and from there to the regeneration tower 4 where the CO2 and H2S are liberated with most of the N2.  Finally the regenerated water returns via pipes 14 and 11 to the top of the absorption column.
