摘要: Abstract The study of selective membrane valve (SMV)—the system which consists two polymeric membranes and a layer liquid between them (moving or non-moving) is presented in this paper. Permeability pure gases such as oxygen, carbon dioxide hydrogen are investigated. Distilled water aqueous solutions potassium carbonate were used carriers. Aqueous was chemical absorbent dioxide. dependencies gas transport parameters SMV on flow rate concentration have been obtained. Two models developed. A first model describes with flowing physical absorbent, the second one—with non-moving absorbent. found to be good agreement experimental results for hydrogen. Carbon permeability through solution well described by model. increasing time-lag non-steady state process when increases also demonstrated
