Integrated CO2, humidity and thermal control by membrane gas absorption
conference paper
In three consecutive studies the use of membrane gas absorption for the recovery of CO2, water vapour and heat has been studied by Stork and the TNO Institute of Environmental Sciences, Energy Research and Process Innovation. This work has financially been supported by ESA and the Dutch national agency NIVR. Recently a new project has been started on the development of a breadboard model to study the process in more detail.
It has been shown membrane gas absorption (MGA) is advantageous for the removal of CO2 from manned spacecraft's (ref.1,2). The system is low in volume and weight. The system is safe and energy efficient. From previous tests it appeared that the system can be used for the removal of heat and moisture as well (ref.3). Later experiments indicate that the system is stable and removal rates for carbon dioxide and moisture can be controlled independently by adjusting the process conditions.
