Study On The Mass Transfer Performance In The Membrane Absorption Process

Membrane absorption technology is novel separate technology that combine membrane separation technology and traditional gas absorption technology. In the membrane process, the gas phase and the liquid phase (absorbent) flow along the different side of membrane, and contact each other through the micro-pores of the membrane. So, compared to the traditional absorber, the membrane absorber can overcome the shortcoming of flooding, loading, channeling, etc,. So, membrane absorption technology has advantages of big special mass transfer area and flux, big operating range of gas or liquid velocity, etc,. In the membrane absorption process, porous membrane is only used as interface or gas and liquid phase.In the present, the study of mass transfer performance in the membrane absorption process can not be satisfied with the need of theoretical study and engineering applications. So, the deeply experimental and theoretical study for membrane absorption process has important theoretical and practical value.In this thesis, the mass transference in porous membrane has been...
