NOVELTY - Recovery of sulfur from the products resulting from pyrolysis of sulfur-containing organic material, comprises: carrying out combustion of liquid pyrolysis products to obtain sulfur dioxide; reacting hydrogen sulfide recovered from gases generated in pyrolysis process with sulfur dioxide; and reacting hydrogen sulfide recovered from generator gases, which are produced in the gasification of solid pyrolysis products, with sulfur dioxide to obtain elemental sulfur, pure gaseous fuel and exhaust gases from the liquid products combustion, free from sulfur-containing compounds.    USE - The process is useful: for the recovery of sulfur from products resulting from the pyrolysis of sulfur-containing organic material; for the production of efficient electrical power; and to provide generator gas used as heat carrier for heating the raw material in the pyrolytic reactor (all claimed).    ADVANTAGE - The process: provides recycling of sulfur-containing products comprising vulcanized polymers, e.g. used tires; does not release sulfur containing compounds into the atmosphere hence environmentally friendly; and is energy-efficient. The process provides electric power without environmental contamination and without the formation of non-usable by-products.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) an efficient electrical power production process, comprising: the fuels are gaseous and liquid fractions of pyrolysed tire shreds; the liquid fraction obtained from a pyrolysis step is used directly for power production; the gaseous fraction of the pyrolysis products and the gas generated resulting from the gasification of solid pyrolysis products are cleaned from hydrogen sulfide using the monoethanolamine or similar process resulting in hydrogen sulfide stream and in clean gas stream; and the exhaust gases from power production from the liquid fraction of pyrolysis are mixed with separated hydrogen sulfide to result in a modified Claus process, such that no sulfur-containing compounds are released into the atmosphere; and    (2) an environmentally clean process for utilizing the output of the pyrolysis of sulfur-containing organic materials, comprising; the pyrolysis output comprises gaseous, liquid and solid sulfur containing products; the liquid product is used as a fuel for electric power generation; the solid carbonized product is gasified and the obtained generator gas is used as a heat carrier for heating the raw material in the pyrolytic reactor; the partly cooled generator gas together with the pyrolysis gas leaving the pyrolytic reactor after separation from condensed liquid pyrolysis product, undergo cleaning from hydrogen sulfide and are used as a pure fuel for electric power generation; elemental sulfur is regenerated by co-processing the hydrogen sulfide, extracted from gases cleaning, and the exhaust gases formed during the liquid product combustion, which contain sulfur dioxide, where the co-processing of hydrogen sulfide and exhaust gas streams is performed using a modified Claus process.
