Purification of BIO-GAS by Vacuum Pressure Swing Adsorption was evaluated to produce Fuel Grade Methane (FGM). Two different adsorbents were employed to evaluate the process performance with equilibrium-and kinetic based adsorbents. Carbon molecular sieve 3K was employed as the example of a kinetic adsorbent because methane diffusion is extremely small. A five-step. cycle configuration (Feed, Intermediate Depressurization, Blow Down, Purge, And Pressurization) was employed to compare with results obtained with a four-step cycle without intermediate depressurization. The effect of different operating variables like step times and pressure conditions of the cycle was analyzed.
