Seminar - Some Aspects of Multiphase Flow Research by Prof Raymond Lau

Date: 30 September 2015 (Wednesday)

Time: 11:00 am – 12:00 pm

Venue:EF305, The Hong Kong Polytechnic University

Abstract:

Many industrial processes involve the operation of multiple phases of gas, liquid, and solid. The complex interactions among the gas, liquid and solid can post challenges in measurement and characterization of the system properties especially under extreme operating conditions. Bubble column reactor is one multiphase system that is widely used in chemical, petrochemical and biochemical industries. This talk will touch on the characterization of bubble size distribution, and the liquid weeping problem that is present in bubble column operations. The use of gas-solid operations in the separation of heavy metals in incineration bottom ash will also be reported.
