Raman spectroscopy for the optimization of hydrogen usage in refineries

Approximately 700 refineries are in operation worldwide, producing a range of petroleum products including gasoline, diesel, jet fuel, liquified petroleum gas (LPG) and fuel oils.

Approximately 700 refineries are in operation worldwide, producing a range of petroleum products including gasoline, diesel, jet fuel, liquified petroleum gas (LPG) and fuel oils. The primary refining process is the distillation of crude oil by an atmospheric distillation unit to separate those fractions that will boil up to about 350°C and 1 barg–2 barg (C1–C17+). A second vacuum distillation unit (VDU) further separates the light- and heavy-vacuum gasoil fractions derived from the bottoms of the atmospheric distillation tower (C18–C38+). An oil refinery contains several different process units to further refine the primary distillate fractions derived from the atmospheric distillation uni
