Biogas purification project: 1. Process control design is reasonable, automation level is high, plant production process is stable, easy to operate, convenient start-up and shutdown, and on-site unattended.2. Through process optimization and improvement, simplify the process, all equipment can be skidded ahead of time in the plant, reducing the on-site installation links and saving investment compared with other purification methods.3. Biogas only needs to be pressurized to 8 kg (0.8Mpa) to enter the purification process. Compared with other purification methods, the power consumption of compressor is greatly reduced, and the energy consumption is reduced by more than 20% compared with other purification methods.4. When two-stage PSA is used and tail gas is fully utilized, the natural gas yield can reach 95% at the lowest. If the decarbonized tail gas is recovered to produce liquid carbon dioxide, the natural gas yield can also reach 100%.
