Defoaming Additives in Horizontal Multiphase Flow – Impact on Flow Regime and Separations

Recorded On: 09/15/2013

The Effect of Surfactant on Stratified and Stratifying Gas-Liquid Flows

The inlet conditions of the fluids entering a separation vessel have a significant impact on the performance of the separator. In this webinar we consider the dynamics of a stratified/stratifying gas-liquid flow in horizontal tubes.

This webinar is categorized under the Projects, Facilities, and Construction discipline.

Professor Omar K. Matar

Prof. O. K. Matar (OKM) is an Exxon-Mobil Fellow and Professor of Fluid Mechanics in the Department of Chemical Engineering, Imperial College London. OKM’s current research interests are in the area of multiphase flows with applications in oil-and-gas flow-assurance, crude-oil processing, enhanced oil recovery, process intensification, coating flow technology, and manufacturing. OKM has recently been invited to review the field of thin films in Rev. Mod. Phys. (impact factor 51).

OKM is the current coordinator of the Fluid Mechanics Focus Area at Imperial and has received £11M funding (£8M as Principal Investigator) from the Engineering and Physical Sciences Research Council, UK. OKM is the director of the Transient Multiphase Flow consortium, which comprises a number of oil-and-gas operators (inc. BP, Chevron, Petrobras, Statoil, TOTAL), design- and software-houses. The research council and industrial funding has been used to study phase inversion in concentrated emulsions, flows over rapidly rotating discs (reactors), nonlinear bubble sound interactions, fouling in heat exchangers in crude oil distillation units, dynamics of liquids spreading on compliant substrates, multiphase flow in large-diameter pipes, advanced experimental and numerical methods for the prediction of complex vapour liquid annular flows, and interfacial behaviour in stratified and stratifying annular flows. OKM is also the director of the EPSRC Programme Grant (£5M), MEMPHIS, to produce the next-generation predictive tools for multiphase flows.

OKM has co-authored 130 articles in prestigious journals and has an h-index of 26. He is the Editor-in-Chief of Multiphase Science and Technology, an Associate Executive Editor of Journal of Engineering Mathematics, and on the Editorial Board of International Journal of Multiphase Flow.
