Technology Overview
The removal of sulfur from hydrocarbon fuels reduces sulfur dioxide emissions that result from combustion of those fuels and prevents the poisoning of expensive catalysts that use these fuels for other purposes. However, current methodologies are still not fully effective in removing all of the sulfur and are expensive. The patented invention achieves efficiencies and lowered sulfur levels previously unobtainable without extensive processing and cost. It includes a system and process for removing elemental sulfur compounds from hydrocarbons including liquid fuels using methods using a stepwise process wherein hydrosulfurization reaction products are condensed at relatively low temperatures to separate a liquid product from a hydro-desulfurization (HDS) containing gas in a vapor phase.
Advantages
- Achieves efficient and improved removal of sulfur from hydrocarbon fuels
- Reduces the sulfur dioxide emissions resulting from combustion of those fuels
- Prevents the poisoning of expensive catalysts that utilize these fuels for other purposes
