OIL RIG - CRUDE OIL Crude oil is a naturally occurring hydrocarbon. Crude oil is found deep underground. Oil reserves are extracted by oil rigs on land and on the oceans / seas. On land, ‘crude oil’ is piped directly to refineries. Huge oil tankers often transport crude oil from oil rigs at sea, to refineries. Crude oil is a valuable commodity, as it can be refined (distilled) into fuels, chemicals and processed into plastics. Crude oil is difficult to find and expensive to extract. |
CRUDE OIL REFINERY AND DISTILLATION Refineries ‘distil’ (distillation) crude oil, manufacturing gas, petrol, diesel, heating oils, naphtha (important for plastics), ethylene and polyethylene. Bitumen / asphalt is also produced. Naphtha is processed into ‘plastic’ granules, in a processing plant. |
|
FACTORY MANUFACTURED PRODUCTS Many types of plastic granules are manufactured. They are used in turn, to manufacture a vast range of products. |
