Technology Type

Most Products of Crude and Vacuum Distillation in Refineries contain a significant amount of Sulfur that must be removed prior to further processing or use.

Hydrotreating or Hydrodesulfurization refers to a set of Operations that remove Sulfur and other Impurities.

During Hydrotreating, Crude Oil Cuts and other refining fractions are selectively reacted with Hydrogen in the presence of a Catalyst at relatively high temperatures and moderate pressures.

The process converts undesirable Aromatics, Olefins, Nitrogen, Metals, and Organosulfur Compounds into stabilized Products.

Some Hydrotreated Cuts may require additional Processing to meet final Product specifications.
