Abstract

Sulfur recovery apparatus, in particular to produce elemental sulfur from a gas containing hydrogen sulfide, characterized in that it comprises an elongated and closed metallic vessel and having inside a combustion chamber, means injection of air and said gas in said chamber, conduits (1) near said opposite end of said chamber communicating with the inside of it following the exterior of said chamber, and returning towards the entrance end of it, a first tubular plate extending from the wall to wall of said container holding the open ends of the conduits (1) and a portion of said chamber near the inlet end thereof, a second tubular plate holding said opposite end of said chamber extending from wall to wall of said container and parallel to said first tubular plate, conduits in said container that essentially surround said combustion chamber and connect said tubular plates, a first wall impervious to gas and extending from said first tubular plate to the outside of said container adjacent to said first tubular and wall to wall plate of said container, thereby defining a first and a second gas-impermeable chambers, each of said chamber thus defined being in communication with separate groups of said connection conduits supported by said first tubular plate, the open ends of the conduits (1) being in communication with said second chamber , two outlet ports in said second chamber, a gas impermeable wall extending from said first partition wall to the container wall facing said partition wall and from said first tubular plate to the end of said container adjacent thereto, for dividing said first chamber into two compartments, an intake port in each of said compartments a second gas-impermeable partition extending from said second tubular plate to the end of said container adjacent to it and from wall to wall of said container, thereby defining a third and fourth gas-impermeable chambers, each one of said chambers thus defined being in communication with separate groups of said connecting conduits adjacent to said second tubular plate, an outlet port in said fourth chamber, a gas impermeable wall extending from said second partition wall to the wall from the container facing said partition and from said second tubular sheet to the end of said container adjacent to said second tubular sheet, for dividing said third chamber into two compartments, and an exit port in each of the above-mentioned compartments.
