Abstract

Buluş, kolon sisteminde kriyojenik damıtma aracılığıyla hava ayırmaya yönelik bir yöntem ile ilgili olup, burada çift tek aşamalı hava kompresörü (15, 25) seri olarak bağlanmaktadır ve sıkıştırılmayan havanın genişlediği iki türbine (17, 27) bağlanmaktadır. Kompresörler, kolon sisteminden oksijenin buharlaştığı bir değişim hattında soğuk yüksek basınçlı havayı sıkıştırmaktadır.The invention relates to a method for separating air by means of cryogenic distillation in the column system, wherein the double single-stage air compressor (15, 25) is connected in series and is connected to two turbines (17, 27) in which the uncompressed air expands. The compressors compress the cold high pressure air in a change line where oxygen evaporates from the column system.
