Process for the recovery of sulfur from sulfur containing gases with high efficiency.

摘要

Process for the recovery of sulfur from sulfur containing gases with high efficiency.; The invention relates to a process for recovering sulfur from sulfur containing gases with a high sulfur recovery efficiency of at least 99.8%.; According to the process of the invention a tail gas of a Claus type hydrogenated with a sulfur recovery efficiency of at least 97% and having a concentration of 0.1-0.7% oxygen vol., and subsequently the H {2} S is removed from the resulting gas stream, for example, by selective oxidation at a temperature between the temperature of dew point of water and 280 ° C, and cooling to a temperature 80-115ºC.; The process of the invention allows recovery efficiencies total sulfur of at least 99.8%.
