Foam Fractionation

Paul Stevenson undertook four chemical engineering degrees and his post-doctoral training at the University of Cambridge, UK. Currently he is faculty at the University of Hull, a guest professor at the China University of Petroleum, adjunct associate professor in the Reservoir Engineering Group of the University of Western Australia, and chief technical officer at Lower Belford Resources. He previously held academic positions at the Universities of Auckland, New Zealand, and Newcastle, Australia. His research work lies at the nexus of multiphase flow and surface science and involves investigations into enhanced oil recovery, gas-liquid mass transfer and mineral flotation.Xueliang Li received his master’s degree from Hebei University of Technology, China, where he researched foam fractionation in collaboration with Tianjin Kangyi Biotechnology Co., Ltd. He subsequently worked directly for the company, participating in the design of the only industrial protein foam fractionation units in the world. He commenced doctoral studies at the University of Newcastle, Australia, and then transferred to the University of Auckland, New Zealand, where he worked as a research assistant in the Department of Chemical and Materials Engineering. Upon graduation, he joined Lanzatech NZ Ltd., Auckland, New Zealand and currently leads their bioreactor scaling up effort.

"This is an excellent, well-written book. It can appeal to a range of readers from those interested in foaming out wastes from fish tanks to those concerned with inexpensively recovering enzymes from dilute industrial and waste solutions. I learned a lot reading the early draft even from the introductory chapter…" —Robert D. Tanner, Emeritus Professor, Vanderbilt University, Nashville, Tennessee, USA and Visiting Associate, California Institute of Technology, Pasadena, USA"The authors’ deep appreciation for and extensive knowledge of foam fractionation shines through in their writing. They have written a lucid, approachable, and in-depth account of an important but poorly understood topic."—Czarena Crofcheck, Associate Professor and Director of Undergraduate Studies, Biosystems and Agricultural Engineering, University of Kentucky, Lexington, USA
