Numerical analysis on purification of methane through the hollow fiber membrane system
Yongtaek Lee and Kyungwhan Cha
Chungnam National University, South Korea
The polysulfone membrane was found to be applicable to the selective removal of CO2 from a biogas, resulting in
preparation of the relatively concentrated methane. The purified methane might be utilized as a vehicle fuel if the methane
concentration is kept higher than the 95 mole %. Generally speaking, the concentration of methane in the biogas is around 20
mole %, which should be upgraded using a cascade operating system. Even if there are several conventional technologies, the
membrane system is known to be not only a new technology, but also an economical method. The cascade membrane system
may be constituted of either two membrane modules or three membrane modules, depending on the input biogas conditions
and the degree of purification of methane. In this study, a theoretical analysis on the cascade membrane system is proposed
and a proper numerical technique is applied to solve the obtained differential equations where the permeate flow rate and the
concentration of the each component will be described in terms of the permeability and the partial pressure difference across
the membrane. As the operating conditions are changed, the obtained flow rate and the concentration of methane as a product
are found to be severely affected. As a design tool, this numerical analysis is strongly recommended since the proper operating
condition will be suggested together with the suitable recycle flow rate for the target goal such as the recovery ratio and the
purity of methane in the final product. The cascade schemes and the analysis results will be presented.
