All nations depend on the combustion of vast amounts of petroleum fuels to generate electricity and to power their industrial sectors. Worldwide energy consumption is forecast to continue its dramatic growth. The US's Department of Energy Information Administration (EIA) has forecast petroleum product consumption worldwide will increase to 40% by 2020. Currently, 800 worldwide refining operations refine 75 million barrels of crude oil per day. Currently, more than 50 crude oil producing countries fill the 75 million barrels per day worldwide petroleum demand; approximately 75% of that crude oil is produced from sour crude and need to be desulphurized before or after refining for consumer use.
Fossil fuel costs are some of the most significant factors affecting the worldwide economy. Sulphur removal in crude oil and other petroleum products provides an economic advantage by equalizing price differentials between high sulphur crude oils and residual fuel oils and by allowing greater use of domestic reserves that are currently underutilized because of their high sulphur content. Sulphur removal in refined petroleum products is essential to meet tighter and tighter environmental standards for all countries.
