| Abstract: | The molecular sieve purification system for a 35000m^3/h air separation unit at Shougang is briefly introduced. Local modifications and rational operations have been performed on the molecular sieve purification system to solve the problem of off-grade carbon dioxide content in its outlet air. The modifications and operations resulted in qualified and constant carbon dioxide content, which is important for long-term stable operation of the whole air separation unit. |
