Petroleum Refinery Processes

Hydrogen Recovery by Pressure Swing Adsorption

Pressure swing adsorption (PSA) is a process for purifying hydrogen in a petroleum refinery by removing other hydrocarbon gases. The PSA unit uses molecular sieves to adsorb hydrocarbons and impurities

Solvent Deasphalting Process in Petroleum Refinery

Solvent Deasphalting is an extraction process used in petroleum refining to remove the asphaltenes from the refinery residues to prepare a suitable feedstock for catalytic conversion unit and lube base

Visbreaking Process in Petroleum Refinery

A Visbreaking (means viscosity breaking) unit is a processing unit in a petroleum refinery that reduces the viscosity of a refinery residue and produces more valuable petroleum products. The Visbreaking

LPG Merox Process in Petroleum Refinery

The term Merox is an abbriviation of ” Mercaptan Oxidation”. It is a specialized catalytic chemical process created by UOP (Universal Oil Products) applied for the chemical treatment of petroleum distillates to

Solvent Extraction Process in Petroleum Oil Refinery

The process of transferring a substance from one solvent to another due to differences in solubility or distribution coefficient between the two immiscible (or slightly soluble) solvents is known as

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

Hydrofluoric Acid Alkylation Process

The acid alkylation process that converts low molecular weight streams into alkylate, high octane, and gasoline blending components in the presence of strong Hydroflouric Acid is called a Hydrofluoric Acid

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.

Alkylation Process In Petroleum Refinery

Alkylation is a chemical process in a petroleum oil refinery in which a high-quality gasoline component (alkylate) is produced by the reaction of low-value light hydrocarbons of the LPG range
