Hydroprocessing

Emergency Depressurizing System of Hydroprocessing Units

An emergency depressuring system (EDS) is the mechanism of quick dumping of high-pressure process fluids from a hydroprocessing reactor in case of emergency situations like fire, thermal excursions, or overpressure.

Avoiding Deactivation of Hydrocracking Catalyst

Hydrocracking catalyst deactivation is the gradual loss of the catalyst’s activity while maintaining the same conversion severity. As the deactivation increases the catalyst temperature has to increase in order to

Key Operating Variables of Hydrocracking Unit

Key Operating Parameters of Residue Hydrocracking Unit Understanding the key process variables is critical for the safe and efficient operation of the hydrocracking unit as the hydrocracking process is exothermic,

Hydrocracking Chemical Reactions Theory

Hydrocracking is a catalytic hydrogenation process in which high molecular weight feedstocks are converted and hydrogenated to lower molecular weight products. Cracking will break bonds, and the resulting unsaturated products

Hydrocracking Process in Oil Refinery

Catalytic cracking of heavy hydrocarbons in the presence of hydrogen is known as hydrocracking. The hydrocracking process converts heavy, high-boiling petroleum feedstock into lighter products (naphtha, kerosene, diesel, etc.) or

Regeneration of Hydrotreating Catalysts

Regeneration is the process of restoring the activity of the catalyst by removing coke from its surface. It also involves the recovery of the physical properties of the catalyst. Regeneration

Hydrotreating Catalysts

The primary function of Hydrotreating catalysts is to remove sulfur, nitrogen and other contaminants from the refinery feedstocks. In addition, they improve product properties by adding hydrogen and in some

Reducing Coke Formation on Hydrotreating Catalysts

Coke formation is the deposition of hydrogen deficient carbonaceous material over the catalyst surface. Generally, it is formed by thermal condensation, de-hydrogenation, and polymerization reactions of hydrocarbons. The coke covers

Improving Hydrogen Partial Pressure in Hydrotreating Units

Hydrogen Partial Pressure (HPP) is a critical parameter related to the performance of the Hydrotreating unit. The hydrotreating reactions are favored by high hydrogen partial pressure. Hydrogen Partial Pressure is
