Designing & Evaluations of a Trace Contaminant Processor for ECLSS Applications: (Thermal- Storage & Combustion Configuration)

Improvement of an air revitalization technology of ECLSS (Environment Control and Life Support System) is one of the key elements in development and operation of future human space systems.

The paper summarizes a trace-contaminant control system which employs “thermal storage / combustion” method for reduction of cabin and equipment-generated off-gases. For comparison, the International Space Station will be equipped with a trace-contaminant system utilizing “oxidization” method with catalyst substances. Preliminary functions of the processor were also evaluated to determine the designing parameters for a space system hardware. The results indicate the capability of processor under large volumes and high concentration of trace gases, and its systematic feasibility.
