Petrochemicals are chemical products made from raw materials of petroleum or other hydrocarbon origin. Although some of the chemical compounds that originate from petroleum may also be derived from other sources (such as coal or natural gas), petroleum is a major source of many. This article is mainly intended to discuss organic compounds or materials that are not burned as fuel (see also Petroleum product). The two main classes of petrochemical raw materials are olefins (including ethylene and propylene) and aromatics (including benzene and xylene isomers), both of which are produced in very large quantities. At oil refineries, olefins are produced mainly from hydrocarbons by processes such as fluid catalytic cracking and steam cracking. At oil refineries, aromatic hydrocarbons are mainly produced by catalytic reforming or similar processes. From these basic building blocks is made a very wide range of chemicals and other materials used in industry - monomers, solvents, detergents, and adhesives. From the monomers, polymers or oligomers are produced for plastics, resins, fibers, elastomers, certain lubricants, and gels. World production of ethylene is around 110 million tonnes per annum, of propylene 65 million tonnes, and of aromatic raw materials 70 million tonnes. The largest petrochemical industries are to be found in the USA and Western Europe, though the major growth in new production capacity is in the Middle East and Asia. There is a substantial inter-regional trade in petrochemicals of all kinds. Primary petrochemicals are divided into three groups depending on their chemical structure:

Well,since they'll probably be wearing underpants anyway,why not just cut out the shorts altogether,as long as all the same team's underpants are the same colour it shouldn't be a problem. Answered by slightlystoutbob - Tue Nov 27 10:02:37 2007 How much of the oil the U.S. uses is used as fuel, and how much is used for plastics or other petrochemicals? Q. If possible, please point to helpful articles or official statistics in your answer. Asked by dcmisner - Sun Feb 5 01:11:24 2006 - - 3 Answers - 1 Comments A. As you have probably discovered by looking at the DOE data above, the answer to this question is difficult because the data is grouped in such a way that 'industrial use' may include use of oil as industrial fuel, as well as for petrochemical feed stock. I turned to BP, which publishes some of the industry's best statistical reports and found this: For oil consumption in USA in 2004 (2005 isn't out yet): Gasoline: 46% Middle distillates: 28.9% Fuel oil: 5.2% Others: 20.4% 'Others' consists of refinery gas, LPG, solvents, petroleum coke, lubricants, bitumen, wax, refinery fuel and loss. Since many plastics and petrochemicals are made from natural gas or oil this makes your question even more difficult to answer. It is likely that most… [cont.] Answered by carbonates - Sun Feb 5 11:41:54 2006 which is better for the ecology as a resource hemp or petrochemicals?
