Air Revitalization System for Japanese Experiment Module

It is necessary to remove carbon dioxide (CO2) and other contaminant gases generated from the crew and nonmetallic materials to keep the allowable level of them for the long duration life support in the space station. Therefore, the Air Revitalization System (ARS) shall be provided in the space station. The ARS for Japanese Experiment Module (JEM) consists of a regenerative CO2 removal system and a trace contaminant control system (TCCS).

A solid amine CO2 removal system has been evaluated as the preferable technology.

An adsorption and catalytic oxidizing method has been selected for the TCCS.

This paper describes the outline of the investigations and study results of the ARS for JEM implemented on the phase B preliminary study (entrusted by NASDA) and subsequent activity.
