In this study, design of lab scale device for determination of separation properties of membranes is presented and analyzed. Device operates with different gas pressure between chambers, whereby gas streams perpendicular to the membrane. Using appropriate acquisition system and applying mathematical formulas, mechanism for gas transfer through the membrane is determinate. Polymer membranes based on zeolite are synthesized and tested by lab scale device. The membranes with various content of zeolite are tested with CO2 gas until optimal composition of membrane components is established. Beside good mechanical and structural properties of applied membrane, suitable values of permeability with good agreement with the literature data are obtained.
U ovom radu je prikazano i analizirano konstrukcijsko rešenje laboratorijskog uređaja za određivanje separacionih svojstava membrana. Rad uređaja je baziran na razlici pritisaka između komora, pri čemu gas struji normalno na poprečni presek membrana. Odgovarajućim sistemom za akviziciju podataka i primenom odgovarajućih matematičkih formula određen je mehanizam prenosa kroz membranu. Polimerne membrane na bazi zeolita su sintetizovane i testirane na uređaju. Membrane sa različitim udelim zeolita su testirane na CO2 gas, dok nije ustanovljen optimalan sastav komponenti za sintezu membrana.Pored dobrih mehaničkih i strukturnih svojstava testirane membrane, dobijene su zadovoljavajuće vrednosti permeabilnosti koje su u saglasnosti sa drugim autorima.
