MODELLING STUDY OF TEMPERATURE EFFECT ON THE EFFICIENCY OF INDUSTRIAL HYDROPURIFICATION PROCESS

Hydropurification, or hydrotreating, is a process where hetero atoms such as sulfur, nitrogen, oxygen and metals are removed and carbon bonds such as olefinic and aromatic bonds are saturated. Hydropurification process is extensively utilized in the chemical/petrochemical industries and oil refineri...
