  • Process for the removal of SO, HCN and HS and Optionally COS, CSand NHfrom a gas stream
    Patent number: 7655205
    Abstract: Disclosed is a process for the removal of sulfur from a gas stream containing sulfur dioxide, hydrogen cyanide and hydrogen sulfide. The process includes a hydrogenation step, a hydrolysis step, an ammonia removal step and a hydrogen sulfide removal step. An aqueous alkaline washing liquid is used in the hydrogen sulfide removal step and with the spent sulfide containing washing liquid being regenerated using an oxidation bioreactor that utilizes sulfide oxidizing bacteria such as autotropic aerobic cultures of Thiobacillus and Thiomicrospira.

  • Process for the removal of s02, hcn and h2s and optionally cos, cs2 and nh3 from a gas stream
    Publication number: 20060272502
    Abstract: The invention relates to a process for the removal of SO2, HCN and H2S and optionally one or more compounds from the group of COS, CS2 and NH3 from a first gas stream, which process comprises the steps of: (a) removing SO2 from the first gas stream by contacting the first gas stream in a hydrogenation zone with a hydrogenation catalyst in the presence of hydrogen to obtain a second gas stream; (b) removing HCN and optionally COS and/or CS2 from the second gas stream obtained in step (a) by contacting the second gas stream in a hydrolysis zone with a hydrolysis catalyst in the presence of water to obtain a third gas stream; (c) removing NH3 from the third gas stream by contacting the third gas stream in a NH3-removal zone with an aqueous acidic washing liquid to obtain an ammonium-comprising aqueous stream and a fourth gas stream; (d) removing H2S from the fourth gas stream by contacting the fourth gas stream in a H2S-removal zone with an aqueous alkaline washing liquid to obtain a H2S-depleted gas stream and

  • Process for gas incineration
    Patent number: 6019953
    Abstract: There is provided a process for the incineration of gases containing sulphur compounds by contacting these gases with an oxygen-containing gas in the presence of a catalyst composition comprising (i) a metal selected from bismuth, molybdenum and chromium as a first metal component and (ii) at least one Group IIA metal as a second metal component, supported on a refractory oxide carrier not being a carrier comprising both aluminum and phosphorus.
