Process for the production of sulfur, starting from the hydrogen sulphide contained in the natural gas, or in the associated gas and possible disposal of the thus obtained sulfur

Abstract From the Canadian patent

Process for the production of sulfur, obtained in pure form and possibly , easily disposable even at ambient temperature starting from hydrogen sulphide , contained in natural gas which includes: a) oxidizing a portion of hydrogen sulphide to sulfur dioxide; b) dissolving in water the sulfur dioxide obtained in step (a) ; c) carrying out the reaction (I) : 2H2S+S02 .fwdarw. 3S+2H20 (I) making the remaining hydrogen sulphide to react with the solution prepared in step (b); and d) using the thus obtained sulfur suspension for the production sulfur or, alternatively, to use it for the disposal of the sulfur itself in a site reserved for such purpose.
