Abstract
The process of mass transfer is very important in the field of technical science. Mass transfer occurs when the component in the mixture moves in the same phase or from one phase to another because of concentration difference. One of the column types which is quite popular is packed bed which shape is silinder like. Usually it can keep on erecting when we put the packing in it. Because the wide use of packed bed, more information and study about the coefficience of mass transfer in the column of packed bed are needed Research was conducted by implementing the adsorption system with the local active carbon as it's. A absorber and acid solution of benzoat as its and adsorbat, the packed bed with its diameter 63 mm and the height of particle 40 cm. The dilution rate of different flow is reaching 10 mls to 30 mils with the starting concentration between 0,01 to 0,03. The result of the research showed that the concentration value would become smaller as the liquid rate in creased with constant starting concentration. So that the coefficient value of mass transfer was between 0,03287-0,033905-1 or became greater as the liquid rate was increasing with constant starting concentration.
