An automated computer controlled apparatus for gas permeability measurements through polymeric membranes is described in detail. The apparatus was specifically designed to operate with hydrocarbon streams and acid gases (CO2, H2S) and therefore special care was devoted to the control devices. The maximum capacity of the apparatus is 100 L/h at temperatures up to 70DEGREESC and pressures in the 0 15 atm range. Permeability measurements of biogas components (CH4, CO2, H2S) and their separation factors through experimental hollow fibre membranes are presented as typical data of the equipment described.
