Abstract:
Sulfur is naturally present as an impurity in fossil fuels. When burned, the sulfur is released as sulfur dioxide, an air pollutant responsible for respiratory problems and acid rain. Environmental regulations increasingly restrict sulfur dioxide emissions, forcing fuel processors to remove the sulfur from both fuels and exhaust gases.
The cost of removing sulfur from natural gas and petroleum is high. In natural gas, sulfur is present mainly as hydrogen sulfide gas (H2S), while in crude oil it is present in sulfur-containing organic compounds which are converted into hydrocarbons and H2S during the hydrodesulfurization. This well-established process uses partial combustion and catalytic oxidation to convert about 97% of the H2S to elemental sulfur. Authors recommend implementation of Distributed Control System (DCS) CENTUM CS3000 to automate the removal process in petroleum refining.
