<p num="1"><br/><br/><br/>A method for generating energy from sulphur combustion without causing harmful <br/><br/>emissions to the environment entails steps of evaporating liquid sulphur to <br/>generate <br/>sulphur dioxide gas and sulphur vapor, combusting the sulphur vapor with <br/>oxygen gas <br/>to generate heat, and reducing (either at high temperature or catalytically) <br/>the sulphur <br/>dioxide to carbon dioxide and sulphur vapor by reacting the sulphur dioxide <br/>with <br/>carbonyl sulfide. The carbonyl sulphide can be generated by reacting hydrogen <br/>sulfide <br/>with recycled carbon dioxide that is recycled by condensing sulphur vapor, <br/>carbon <br/>dioxide and water to yield liquid sulphur, elemental sulphur, steam and carbon <br/>dioxide. <br/>Energy in the hot reactor products (SO2 gas and sulphur vapor S2) and steam <br/>can be <br/>harnessed using this emission-free process. Likewise, this process can be used <br/>to <br/>produce elemental sulphur and/or carbon monoxide without polluting the <br/>atmosphere. <br/>Furthermore, this process can be used for the transshipment by pipeline of <br/>sulphur by <br/>transporting it as carbonyl sulphide.<br/></p> |
