Bubble columns often involve liquid phases which are impure or which contain dissolved components. Explain clearly the impact such dissolved components will have upon the gas-liquid behavior in the bubble column. A pharmaceutical compound is synthesized by means of a gas-liquid reaction. This reaction has traditionally been achieved using a batch manufacturing approach and a bubble column is used to achieve the gas-liquid contact. The company would like to switch to a continuous bubble column however in order to increase its throughput of product. The current batch bubble column is to be retrofitted for use in this new continuous system (i.e.:the column geometry will remain the same). The bubble column has a diameter of 0.7m and the fully aerated gasliquid height during operation is 2.5m. Under batch conditions, a volumetric flowrate of 0.15 m^3/s is supplied to the column. The top f the column is at atmospheric pressure. (0) if 0.2m^3/s of liquid reagent is to be processed in the continuous column, estimate the gas flowrate required in order to maintain the same power to liquid volume ratio as in the batch column (ii) (mi) What impact does doubling the flowrate have upon the average bubble size and the interfacial area?
