    摘要： A compact treatment apparatus and methodology is provided for scavenging at least H2S from an acid gas stream. The vessel is charged with a batch of an aqueous solution of H2S scavenging treatment liquid. Acid gas is discharged from a sparge bar fit with graduated openings, either graduated from small to large or from a few to many and spaced therealong, for distributed discharge into the treatment liquid. The acid gas percolates up through the liquid and into a vessel headspace, the gas being scrubbed of H2S for producing a treated discharge gas. The treatment solution can be an aqueous solution of incorporating one of several active H2S scavenger ingredients including amine-aldehyde compositions or triazines.

    摘要： There is described a process for reducing the concentration of formate based heat stable salts formed in a physical solvent acid gas absorption process (12) wherein acid gas contaminants such as hydrogen sulfide and carbon dioxide are removed from gas mixtures (30) which include these contaminants. The process comprises the step of contacting the physical solvent containing formate based heat stable salts (46) with a metallic and/or organometallic catalyst (52), preferably the catalyst comprises palladium, zinc, platinum, nickel, or rhodium, and/or salts thereof and/or oxides thereof. The process is particularly suited for physical solvents such as refrigerated methanol, dialkyl ethers of polyethylene glycols, N-methyl-2-pyrrolidones, propylene carbonate, blends of N-acetylmorpholine and N-formylmorpholine, 1,3-dimethyl-3,4,5,6-tetrahydro-2(1H)-pyrimidinone, and the like and particularly gas mixtures containing ammonia as a contaminant.
