    • Air is compressed in compressors 2, 8, 12 and 14. A first flow of the thus compressed air flows through a main heat exchanger 22 from its warm end 24 to its cold end 26 and is liquefied by passage through a valve 28. Two second stream of compressed air are taken. One is expanded in expansion turbine 44, the other in expansion turbine 38. The streams leaving the valve 28 and expansion turbine 44 are separated in a double rectification column 34. Liquid oxygen product is extracted from outlet 60. Part is taken as liquid product and the rest is vaporised by passage through the heat exchanger 22 from its cold end 26 to its warm end 24 and taken as gaseous oxygen product. The ratio of liquid oxygen product to total oxygen product is capable of being varied. Accordingly a chosen but variable proportion of the two second air streams flows to the double rectification column 34 and a chosen but variable proportion of the two second air streams is returned to the arrangement of compressors 2, 8, 12 and 14 at a region intermediate compressors 2 and 8.
    • 空气在压缩机2,8,12和14中被压缩。如此压缩的空气的第一流从其热端24流过主热交换器22到其冷端26并通过阀28液化。两秒 采取压缩空气流。 一个在膨胀涡轮机44中膨胀,另一个在膨胀涡轮机38中膨胀。离开阀28和膨胀涡轮机44的流在双精馏塔34中分离。液态氧产物从出口60中抽出。部分作为液体产物并且 剩余部分通过热交换器22从其冷端26到其热端24而被汽化,并被视为气态氧产品。 液氧产品与总氧产品的比例能够变化。 因此,两个第二空气流的选定但可变的比例流向双精馏塔34,并且选定但可变比例的两个第二空气流被返回到压缩机2,8,12和14的中间压缩机区域 2和8。
