Petroleum refining

Japanese: 石油精製 - せきゆせいせい（英語表記）petroleum refining

A technical system for processing crude oil using physical and chemical means to produce various petroleum products. After World War II, due to the development of large oil fields in the Middle East, the growing size and speed of tankers, and the need for oil-consuming countries to save foreign currency for purchasing oil, refining in the country of consumption became the norm. However, in recent years, oil-producing countries have been increasingly attempting to refine their own oil locally and export petroleum products instead of exporting crude oil, in order to develop domestic industries and increase added value.

原油を物理的･化学的手段を用いて加工し，各種の石油製品を生産する技術体系。第2次大戦後は中東地域における大油田の開発，タンカーの大型化と高速化，石油消費国における石油購入のための外貨節約の必要，などの理由により，石油の消費地精製が主となった。しかし最近は産油国が国内産業育成，付加価値の増大の立場から，原油を輸出するかわりに，みずから現地で石油精製を行い，石油製品を輸出しようとする動きが高まっている。
