大型空分设备分子筛出口空气中CO_2含量超标分析与处理

Analysis and treatment of over-standard carbon dioxide content in the outlet air from molecular sieve adsorber in the larger scale ASU

介绍分子筛吸附器出口空气中二氧化碳含量超标,采取优化操作手段,但仍未消除故障,相反,分子筛出口空气中二氧化碳含量继续升高。立即对该套空分进行停机处理,分子筛检修后运行正常。

The phenomena of over-standard carbon dioxide content in the outlet air from molecular sieve adsorber is Introduced. Theoptimizing operation means were failed to eliminate the fault, however, the carbon dioxide content in the outlet air from molecular sieveadsorber was continue to rise. This ASU was shut down immediately. The molecular sieve adsorber was operating normally after maintenance.
