Hydrotreater
A Hydrotreater or hydro-desulfurization (HDS) unit is the process equipment used in petroleum refining to remove sulfur and nitrogen compounds from natural gas and other refined petroleum products like deisel, gasoline, and jet fuel. In petroleum refining, it is important to remove sulfur from the process stream in order to:
- Prevent sulfur from poisoning the noble metal catalysts in the subsequent catalytic reforming of the naphtha; and
- Reduce sulfur dioxide (SO2) emissions to meet more-stringent clean fuels specifications.
