Some Technical and Economic Aspects of Residual Fuel Oil Desulfurization

Pages 485-488 | Published online: 16 Mar 2012
 

Abstract

Combustion of residual, the most common type of fuel oil used in industrial and commercial steam generating plants, accounts for about 600,000 tons or 37 percent of the sulfur oxide emissions in New York state. On the average, residual oil available in New York state contains about 2.2 percent sulfur and is consumed at an annual rate of approximately 85 million barrels. The removal of sulfur from many types of residuals should become economically feasible as a result of the development of the HDS and H-Oil hydrodesulfurization processes. From studies recently made, these methods of desulfurization have been estimated to vary from a minimum of no appreciable increase in overall cost to a maximum of about one cent per gallon. The by-product distillates produced in hydrodesulfurization are a very significant factor in making the process economical and the demand for these is increasing at a greater rate than residual.
