| titleOfInvention | Purification of fuel and other gases |
| abstract | 286,633. Koppers Co., (Assignees of Gollmar, H. A.). March 7, 1927, [Convention date]. Materials and compositions for purifying.- Fuel and other gases are freed from hydrogen sulphide, and other acidic constituents by washing in an alkali liquid containing a compound of arsenic or metal of the tin group of qualitative analysis, a prepared mixture of alkali and metal compound, preferably in solution, being added to maintain the strength of the wash liquid. In making up the initial solution equal parts bv weight of sodium carbonate and arsenious oxide are mixed and brought into solution by heating, carbon dioxide being elinainated by boiling. The solution is caused to absorb hydrogen sulphide and is then aerated, forming a thio-arsenate. Sulphidation and revivification are then repeated indefinitely with recovery of free sulphur. Additions of mixtures of carbonate and oxide are made at as low and uniform a rate as is consistent with maintaining the strength of the solution and are preferably made by allowing a solution to flow slowly into the system at the inlet to the absorber.. Alkali is also preferably added in this way except when discolouration of the foam or solution indicating a deficiency necessitates a batch addition. Sodium hydroxide or sulphide may replace the carbonate and other arsenic compounds such as arsenious sulphide may be employed. Other alkalis may also be used as the base and tin, antimony or other metal of the tin group in qualitative analysis substituted for arsenic. The initial mixture contains two atoms of alkali metal to one of arsenic subsequent mixtures for addition to the system altering the ratio to 1 : 1. Specification 280,165 is referred to. |
