Plant capacity: 500~1×10⁴Nm³/h（purifying CH4）
One-stage or two-stage PSA process is adopted to increase the concentration of methane in gas to over 95% to produce CNG or LNG. There is no need to compress the gas. Deoxygenation is needed to guarantee safety. Short process and applicable for wide range of feed concentration. CNG is directly obtained after gas concentrated. Compressing energy cost and investment is very low.
