苏联天然气加工业居世界第三位,次于美国和加拿大。例如,美国所采天然气80%要深加工,为化工行业提取珍贵组分,而苏联所采天然气仅有15%进行了深加工。苏联天然气加工业的发展方向是建立大型天然气综合体。七十年代建立了奥伦堡天然气加工综合体(可制取硫磺、液化气、宽馏分轻烃、氦气、乙烷)和穆巴列克天然气加工厂。阿斯特拉罕天然气化工综合体从1987年
The Soviet Union’s natural gas processing industry ranks third in the world, behind the United States and Canada. For example, 80% of the natural gas it takes in the United States needs further processing, extracting precious components for the chemical industry and only 15% of the natural gas it receives from the Soviet Union. The development direction of the Soviet Union’s natural gas processing industry is to establish a large natural gas complex. In the seventies, the Orenburg natural gas processing complex (sulfur, liquefied petroleum gas, light hydrocarbons with wide fractions, helium, ethane) and Mobariek natural gas processing plant were established. Astrakhan Natural Gas Chemical Complex since 1987
