An initial study of biogas upgrading to bio-methane with carbon dioxide capture using ceramic membranes

• Ceramic membranes can be used for biogas upgrading to biomethane. This membrane pore size determines the flow mechanism of components. Reduced enhance mass transport and selectivity membrane. Supplement depleting energy resources stringent environmental laws regarding atmospheric emissions greenhouse gases, development clean renewable sources has been a great issue. Worldwide, usage is steadily increasing would continue increase in coming years; effects global warming are also becoming more prevalent. Biogas holds promising future sustainable supply low-cost that will minimize gas emissions. Unlike solar wind, does not rely on weather conditions. It stored transported making it easily adaptable changes demand. study utilize technology useful fuel replacing fossil fuels consider limiting factors process found literature which trade-off between permeability selectivity. In doing so, we analyse affect ceramic then introduce methods optimisation. components passed through as feed observe characteristics at various operating conditions with different sizes. was observed all sizes studied, there proportional rise flowrate pressure increased from 0.2 3 bar. Also, an temperature 20 °C 100 favoured general, methane showed higher flux than carbon dioxide irrespective indicating permeation gases related their molecular weight, example, using 15 nm bar, 3.59 2.27 L/min obtained CH 4 CO 2 respectively same trend recorded other sizes, ranges. must noted plays vital role optimisation membrane, being lowest mean studied highest separation factor 1.60 close ideal Knudsen value. Overall, behaviour these determined by interplay – dynamic diffusion rate.
