Hydrotreating in the oil & gas industry

Hydro desulfurisation monitoring

Hydrotreating, often called hydro-desulfurisation, is a refinery process applied to the distillation column sidecuts that that are heavier oil products. The objective is to reduce the sulphur and other components, such as nitrogen and aromatics, by creating a reaction between them and hydrogen, when they are exposed to a catalyst at high temperature. In this way the refinery can meet the requirements for clean fuel specifications, for example for low sulphur/sulfur diesel.
