| titleOfInvention | Method of desulphurization of gases |
| abstract | The invention relates to a process for the desulphurization of gases, in particular gases having a carbon dioxide content of 10 to 99% by volume, such as, for example, acid natural gas, gasification gasifier coal, expansion gases which are not required for gas purification and chemical production. all gases containing hydrogen sulphide and carbon dioxide. Among the known processes for desulfurization of gases, those which produce directly elemental sulfur by oxidation of hydrogen sulfide absorbed in the scrubbing solution are most preferred. However, the desulphurisation process for higher and high CO2 gases has not been mastered since this CO2 strongly changes (reduces) the concentration of hydrogen ions in the scrubbing solution, thereby inhibiting the desulfurization processes. After scrubbing hydrogen sulphide from the gas, the scrubbing solution is led to a so-called digestion, during which the chemical equilibrium is established, so that the subsequent oxidation with finely dispersed air causes essentially The presence of simultaneously absorbed CO2 leads to acidification of the scrubbing liquid and, in the case of the arsenic salts used as an active ingredient, precipitates insoluble sulphide. their temperatures are |
