Abstract
Biogas fuels is effective to alleviate the problem of energy shortage and ecological environment for sustainable
developing in rural China. But CO2 and other impurity in biogas will impede its use for generating high quality energy. In
this paper, water scrubbing technology has been used for biogas upgrading under low scrubbing pressure, and the
influence of CO2 removal rate and CO2 solubility caused by different experimental parameters including the feed gas flow
rate, water flow rate and scrubbing pressure were examined, and the experiments dates were analyzed by SPSS17.0, and
then the corresponding mathematical models were established. The result showed that, under the three scrubbing pressure
level(with normal pressure, 0. 15 Mpa and 0. 3 Mpa), the improve rate of CH volume fraction increased about 15%, and
CO2 volume fraction declined about 20% when scrubbing pressure raised in each level, and under 0.3 Mpa of pressure,
with 0.28 of flow rate ratio of gas and liquid, CO2 removal rate gotten as high as 73.14%.So the method of water
scrubbing under low pressure could be used for biogas preliminary upgrading processing when there is rich of water.
