Simulation comparative study of water scrubbing and propylene carbonate in biogas de-carbonization was dicussed by the software PRO/II,the composition of biogas was that, GH4 was 57%,CO2 was 40%, N2 was 2.8% and O2 was 0.2% when under 2.7,13,0.7 MPa.The results showed that both methods for CH4recovery rate could > 98%,the operating pressure affect the system energy consumption greatly,it should be determined based on terminal biogas application and CO2 recycle value. CH4>93%,CO2展开▼
