Economical operation of Baosteel＇ s oxygen generating system

Baosteel's 60 000 m3/h air separation unit(ASU) is the largest oxygen generating system in China.The operational cost of such a giant system is very high.How to reduce the operational cost is a critical issue.This paper discusses the system's characteristics,the current operational status and the difficulties in reducing the cost,and analyzes relevant indicators,such as the technical and economical indicators of individual units and systems as well as the indicators concerning the costs.The relationship between the cost and each economical indicator and measures to optimize an economical operation of the oxygen generating system are also discussed in this paper.
