Liquefied gas petroleum

Liquefied petroleum gases precipitate asphaltic and resinous materials from cmde residues while the lubricating oil constituents remain in solution. Although all Hquefied gases possess this property to some extent, propane and butane are used to deasphalt residual lubricating oils because of their relative low cost and their ease of separation from lubricating oils.

Evaporation of a relatively-small volume of liquid in an enclosed space can produce a flatmuable or toxic vapour hazard. Leakage, or spillage, of a chemical maintained as a liquid above its atmospheric boiling point by pressure (e.g. liquefied petroleum gases) or as a liquid by refrigeration (e.g. ammonia) can result in a sizeable vapour cloud.

Propane is the most widely used commercial term to describe a family of liquefied petroleum gases (LP-gas or LPG) that also includes ethane and butane. 

Refineries produce more than 2,000 products, but most of these are very similar and differ in only a few specifications. The mam products, with respect to volume and income, are liquefied petroleum gases (LPG), gasolines, diesel fuels, jet fuels, home heating oils (No. 1 and No. 2), and heavy heating oils (No. 4, No. 5, No. 6, and bunker fuel oil). Some refineries also produce asphalts and petroleum coke. 

The Ce-Cg aromatic hydrocarbons—though present in crude oil—are generally so low in concentration that it is not technically or economically feasible to separate them. However, an aromatic-rich mixture can be obtained from catalytic reforming and cracking processes, which can be further extracted to obtain the required aromatics for petrochemical use. Liquefied petroleum gases (C3-C4) from natural gas and refinery gas streams can also be catalytically converted into a liquid hydrocarbon mixture rich in C6-C8 aromatics.
