Gas Permeation Pilot

Facility/equipment: Equipment

    Equipments Details



    Gas permeation is the transport of gas molecules through a membrane material. The permeability and selectivity are the key characteristics to describe the membrane performance. The purpose of the gas permeation pilot is to measure both the permeability and selectivity of pure as well mixed gasses at various temperatures, pressures and flow rates.


    Gas is supplied to the membrane cell at a set temperature, pressure and stage cut. In the membrane cell selective transport of the gasses occurs. Using single gasses the permeation rate is calculated by the pressure decay method. In case of mixed gasses the permeation rate is calculated based on the analyses of the feed and permeate using a micro GC-analyzer.
