The Transfer Process Research Of Hollow Fibre Absorb Sulfur Dioxide

In this paper,the nowadays-worldwide research results of the absorption of sulfur dioxide flue gas of making use of hollow fiber technology were introduced.On the bases of experiment of using citric acid to absorb low concentration sulfur dioxide,based on Duplex Film Theory,the local and overall mass transfer coefficients of the absorption of sulfur dioxide using hollow fiber were deduced theoretically.The foundation method of mathematical model of membrane gas absorption was discussed also.According to the result of experiment,by way of conventional and reasonable supposition to some environment variables,making use of computer software to calculate the transfer coefficients in the membrane absorption process,and using visual method to design the system,in the same time,manifesting the relationship of correlative variable in the membrane absorption process with the overall mass transfer coefficients intuitively.The research result shows:in the hollow fibre membrane absorb sulfur dioxide process,liquid conditions and gaseous conditions are primary control conditions to affect transfer process.They play an important role in the absorption rate of sulfur dioxide in the membrane absorption process.
