Separation of CO2 from Small Gas Molecules Using Deca-Dodecasil 3 Rhombohedral (DDR3) Membrane Synthesized via Ultrasonically Assisted Hydrothermal Growth Method

Figure 4

Effect of hydrocarbon impurities on the performance of DDR3 membrane and its durability test (separation results points C, E, and G were determined at a temperature of 30.1°C, feed pressure of 1 bar, with the CO2 composition of 35.84% (CH4 composition of 64.16%)).
