SISTIM PEMBETULAN KRIOGENIK UNTUK MENGHASILKAN OKSIGEN DENGAN KEMURNIAN RENDAH DAN OKSIGEN DENGAN KEMURNIAN TINGGI

摘要

A cryogenic rectification system having high recovery of both higher purity and lower purity oxygen which employs a side column having a bottom reboiler wherein feed air is partially condensed and the feed air vapor remaining after the partial condensation is turboexpanded prior to rectification.
