阅读说明：本技术 用于通过低温蒸馏来分离空气的方法和设备 (Method and apparatus for separating air by cryogenic distillation ) 是由 伯诺瓦·达维迪安 于 2018-11-08 设计创作，主要内容包括：在通过低温蒸馏在塔系统中分离空气的方法中,该塔系统包括在第一压力下操作的第一塔(1)和在第二压力下操作的第二塔(2),富含氩的流(47)从第一塔的中间点被发送至第二塔的底部,并且富含氩的流(51)从第二塔的顶部被抽出,来自第一塔的富含氮的流(7,13,17)在压缩机(19)中被压缩,压缩后的流在膨胀步骤之后被发送至第二塔的顶部冷凝器(37),并且在冷凝器中汽化的流在涡轮机(41)中膨胀,在涡轮机中,流被至少部分地液化。(In a method for separating air by cryogenic distillation in a column system comprising a first column (1) operating at a first pressure and a second column (2) operating at a second pressure, an argon-rich stream (47) is sent from an intermediate point of the first column to the bottom of the second column and an argon-rich stream (51) is withdrawn from the top of the second column, the nitrogen-rich stream (7, 13, 17) from the first column is compressed in a compressor (19), the compressed stream is sent after an expansion step to a top condenser (37) of the second column and the stream vaporized in the condenser is expanded in a turbine (41) in which the stream is at least partially liquefied.)
