| Abstract: | Leakage of control valve of auxiliary regeneration pipeline at top of molecular sieve adsorber results in short-circuit of not thoroughly adsorpted air and entering of the said air to the master air pipeline at the molecular sieve adsorber outlet, and generates the false of carbon dioxide penetration and the trouble of exceedance of carbon dioxide content in air of molecular sieve adsorber outlet at the end of adsorption. Here, the analysis process for the trouble causes and the treatment method are introduced. |
