  • Patent number: 10066834
    Abstract: A system for carbon capture includes an oxy-fuel combustor for combusting a hydrocarbon with pure oxygen to produce heat energy and carbon dioxide, a COS converter for converting the carbon dioxide to COS, a transport means for transporting the COS, a sulphur recovery unit for recovering sulphur from the COS and an adjunct sulphur-burning power plant for combusting the sulphur to generate energy for powering one or more carbon capture and storage processes.

  • Patent number: 9802153
    Abstract: Disclosed herein is a system and method for sulphur-assisted carbon capture and utilization. The system includes a sulphur depolarized electrolyser (SDE) for receiving electricity, H2O and SO2 and for electrolysing the H2O and SO2 to produce hydrogen and sulphuric acid (H2SO4), a decomposition reactor for receiving and decomposing the H2SO4 into SO3 and H2O, wherein the H2O is recycled to the SDE, a sulphur submerged combustor for converting the SO3 to SO2 and producing Sn vapor, a sulphur power plant for combusting Sn vapor to produce SO2, electricity and heat and for supplying the SO2 and the electricity to the SDE and for supplying the heat to the decomposition reactor. The hydrogen is delivered to a carbon capture and utilization facility. An optional Flue Gas Desulphurisation (FGD) regenerable system removes SO2 from flue gas, a CO2 converter generates COS, and a separator separates the COS from the flue gas.

  • Publication number: 20100242478
    Abstract: A method for generating energy from sulphur combustion without causing harmful emissions to the environment entails steps of evaporating liquid sulphur to generate sulphur dioxide gas and sulphur vapor, combusting the sulphur vapor with oxygen gas to generate heat, and reducing (either at high temperature or catalytically) the sulphur dioxide to carbon dioxide and sulphur vapor by reacting the sulphur dioxide with carbonyl sulfide. The carbonyl sulphide can be generated by reacting hydrogen sulfide with recycled carbon dioxide that is recycled by condensing sulphur vapor, carbon dioxide and water to yield liquid sulphur, elemental sulphur, steam and carbon dioxide. Energy in the hot reactor products (SO2 gas and sulphur vapor S2) and steam can be harnessed using this emission-free process. Likewise, this process can be used to produce elemental sulphur and/or carbon monoxide without polluting the atmosphere.

  • Publication number: 20090235669
    Abstract: A method of generating electrical power using sulfur, the method having the steps of combusting oxygen with a stoichiometric quantity of sulfur comprising predominantly diatomic sulfur to generate hot sulfur dioxide gas; and mixing a cooling gas substantially cooler than the hot sulfur dioxide gas with the hot sulfur dioxide gas to produce a mixed working gas for driving a gas turbine, the mixed working gas having a temperature less than a maximum allowable temperature determined by a metallurgic limit of turbine blades in the gas turbine, whereby the gas turbine generates electrical power.

  • Patent number: 7543438
    Abstract: A gas turbine topping device, which is disposed upstream of a steam-raising section, is used for generating power in the manufacture of sulphuric acid. A sulfur-burning combustor generates hot sulfur dioxide while a pressure-exchanging ejector mixes the hot combustion gases with a cooler gas (e.g. pressurized air, pressurized N2 or recycled sulfur dioxide (SO2) to form a mixed working gas having a temperature below the maximum allowable temperature (metallurgical limit) of the blades of the turbine. The turbine drives an oxygen compressor which supplies oxygen to a bubbling chamber which also receives S8 to produce sulfur vapor for combustion. By using stoichiometric quantities, sulfur dioxide is delivered in requisite quantities to a sulfuric acid plant without any harmful emissions. Useful amounts of electrical power can thus be generated by the gas turbine topping device as well as the downstream steam turbine by harnessing the enormous amount of waste heat involved in the manufacture of sulfuric acid.
