Bubble column reactors suffer from bubble coalescence resulting in a decreased mass transfer efficiency. In order to increase the mass transfer rate in bubble column reactors, a novel reactor is proposed, the Micro-Structured Bubble Column (MSBC). is novel reactor makes use of a wire-mesh serving the purpose of cuing bubbles into smaller bubbles. is increases the specific bubble surface area...

A new method is developed for the determination of bubble size distributions from experimental laser Doppler anemometry (LDA) data through simultaneous measurement of only two orthogonal velocity components and the intermittent time gaps arising out of bubbles passing through the measurement point. An experimentally verifiable assumption of axisymmetry allowed the calculation of the three-dimen...

An automated tension infiltrometer including a soil contacting base to which is mounted a porous plate for interfacing the infiltrometer with the soil to be analyzed. A Marriotte column is positioned in the base so that its open bottom end abuts the porous plate. A bubble tower is also positioned in the base and has a bubbling tube operatively connected between its interior and interior of the ...

modified bubble column extraction with ultrasonic bath (bce-ub) method was used to extract atropine from the stem and leaves of atropa belladonna. optimum condition were obtained with kamada solvent which was chloroform-methanol-ammonia 15:15:1(v/v/v) as extraction solvent, the particle size of  less than  350 µm, an extraction time of 23.95 min, a liquor to material ratio of 15.08 ml/g and  an...
