Properties of Diesel Fuel
Diesel is defined as a fuel comprises of complex hydrocarbons containing carbon atoms from C12 – C20. It mainly includes aromatics, paraffins, and naphthenes. The boiling range of diesel fuel
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
Nelson Complexity Index for Petroleum Refineries
The Nelson Complexity Index measures the secondary conversion capacity of a petroleum refinery by comparing it with the primary distillation capacity. The complexity index provides an easy metric for quantifying
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
Properties of LPG (Liquified Petroleum Gas)
Liquefied petroleum gas or LPG is the term applied to the propane and butane hydrocarbons that exist in the gaseous state under atmospheric ambient conditions but can be converted to
Bitumen Grades and Uses in Road Construction
Bitumen used in the pavement in road construction is classified either according to its penetration or according to its viscosities. Viscosity grading and Superpave Performance grading (PG) systems are the
