Petroleum Refinery Processes

Sulfur is the most common impurity present in the feed of the naphtha reforming unit. The maximum allowable concentration is nearly 0.5 weight ppm expressed as S. Sulfur is poison

Nitrogen is a temporary acid function poison of naphtha reforming Platinum catalyst. Reformer feed nitrogen is normally controlled at 0.1~0.5 wppm and is less frequently present in the reforming feed.

Catalytic reforming catalysts are bifunctional, with the metal and acid sites assumed to be in some “balance” that enables total and effective utilization of the metal and acid sites. Metal-acid

The major process variables that affect the performance of the catalytic naphtha reforming or platforming unit are reactor pressure, reactor temperature, space velocity, hydrogen to hydrocarbon (H2/HC) molar ratio, feedstock

Hydrogen is one of the most important elements in petroleum refineries, and is in various refining processes to upgrade the petroleum products quality. Demand for hydrogen in petroleum refineries has

A dimerization process is a form of polymerization that converts two propylene molecules to generate one C6 olefin molecule that is termed dimate, which is then used as a gasoline

The flaring process in oil refineries refers to the controlled and safe burning of the waste gases that are produced during various refining processes. By burning the hydrocarbon vapours the

In petroleum refining, acid gas refers to a mixture of gases that form acids in a solution with water. The most common types of acid gas are carbon dioxide (CO2)
