Method for removing hydrogen sulfide from sour-gas and converting it to hydrogen and sulfuric acid
Abstract/Contents
- Abstract
- A method for removing hydrogen sulfide from a sour-gas stream is investigated and found to be promising. The method oxidizes hydrogen sulfide to sulfuric acid by reducing aqueous bromine to hydrobromic acid in solution. Sulfuric acid is concentrated to eliminate its bromine content prior to being removed from the system, while the remaining hydrobromic acid solution is electrolyzed to regenerate aqueous bromine and produce hydrogen. The aqueous bromine solution does not react with hydrocarbon components common to natural gas including methane and ethane. This allows the process to both sweeten sour-gas and convert its hydrogen sulfide content to sulfuric acid in a single step. Specific reactor conditions were found to produce sulfur instead of sulfuric acid. Hydrobromic acid electrolysis requires less than half the energy required by water electrolysis and is an inherently flexible load that can shed or absorb power to balance supply and demand. Thus the electrolysis of hydrobromic acid may provide a route to produce inexpensive hydrogen and improve the electric grid.
