Technology Marketing SummaryWith the growing pressure placed on energy efficiency and reliance on fossil fuels, alternative sources of energy are increasingly important. The primary function can be used for the production of hydrogen but a similar process can be applied to create ammonia and propane production.DescriptionOur technology integrates three main components in the production process by integrating the boiler, superheater, and decomposition functions of sulfuric acid (H2SO4) to create sulfur dioxide(SO2) into a single unit. Additionally, our design solves the problem of corrosion due to the high temperatures and concentrated sulfuric acid with the combining the three processes into a single operation and using corrosion resistant components. The integration also makes the process highly efficient & economical by recovering and reusing the acid in the closed-loop process.Benefits
  • Alternative energy production
  • Solves corrosion issues found in other processes
  • Integrates three processes into a single operation for maximum efficiency
  • Closed loop cycle
  • Greater efficiency
Applications and Industries
