Abstract

To disperse oil rapidly and finely in liquid, a bubble column with draft tube installed net (NDT-BC) is proposed. The oil dispersion performance of NDT-BC is compared with those of a standard bubble column (SBC) and a bubble column with draft tube (DT-BC). From these results, NDT-BC is found to have higher performance of oil dispersion than SBC and DT-BC. For NDT-BC the effect of net location and net number on the dispersion performance are examined. An experiment on oil decomposition by using yeast is performed in the three different columns. The oil decomposition performance of NDT-BC is the highest among the three columns.
