Steam Reforming Process for Hydrogen Production
Steam reforming is a method for producing hydrogen gas by the reaction of hydrocarbon in the presence of steam and catalyst. Natural gas, refinery gas, liquefied petroleum gas (LPG), and...

Properties of Kerosene
Kerosene, also called paraffin or paraffin oil, is a flammable pale-yellow or colourless petroleum product with a characteristic odour, intermediate in volatility between gasoline and diesel oil. It is produced...

Sulfur Recovery Unit in Petroleum Oil Refinery
The Sulfur Recovery Unit (SRU) in a Petroleum Refinery is designed to remove H2S from sour gases originating in the various refinery processes and convert them to industrial-grade molten sulfur....

Avoiding Polythionic Acid Attack in hydroprocessing Units
Austenitic stainless steels are extensively used in hydroprocessing units of oil refineries because of their resistance to H2S+H2 attacks at high temperatures and pressures. However, during the shutdown period presence...

Minimum Pressurization Temperature in Hydroprocessing Reactors
The Minimum Pressurization Temperature (MPT) or Minimum Safe Pressurization Temperature (MSPT) is the lowest temperature at which the hydroprocessing reactor can be pressurized again after a shutdown without the risk...

Avoiding Temperature Runaway in Hydroprocessing Reactors
Temperature excursion or temperature runaway is the abnormal process condition at which catalyst bed temperatures go high beyond the normal operating limit on account of uncontrolled hydrocracking reactions. During a...

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...

Catalytic Reforming Process in Petroleum Refinery
Catalytic reforming is the chemical process in oil refineries for converting the low-value heavy naphtha fraction of crude oil into high octane reformate, aromatics rich feed-stock and hydrogen. High octane...

Vacuum Distillation Unit in Oil Refinery
The vacuum distillation unit is designed to process the reduced crude from the atmospheric crude distillation tower bottom in the presence of a vacuum. The Vacuum Distillation Unit separates the...
