ABSTRACT:
The process described is a novel use of two complementary processes, the first of which provides the product to be converted into energy by the second process, related in such a way that the two combined provides an alternative to conventional fuels at a significant economical advantage. Specifically, the burning of sulfur with air or oxygen produces sulfur dioxide which can be combined with water to form sulfuric acid and by electrolysis, the sulfuric acid and water is converted to hydrogen gas. Hydrogen gas is burned as has been the sulfur, each producing thermal energy which is used to produce steam. The steam produced by burning the two fuels, sulfur and hydrogen gas, is used in the pulp mill in exactly the same manner as has been steam produced by burning fuels such as natural gas, fuel oil, coal and wood.
