Kok Siew Ng
Kok Siew Ng joined the Centre for Environmental Strategy as Research Fellow in May 2015. His current research project is primarily focused on resource recovery from wastewater using bioelectrochemical systems. The project is funded by Natural Environment Research Council (NERC) and led by Dr. Jhuma Sadhukhan. This multidisciplinary project is carried out in partnership with academic institutions (Newcastle University, University of South Wales and The University of Manchester) and industrial companies (Tata Steel and Magneto).
Kok Siew completed his MEng Chemical Engineering with Chemistry at the University of Manchester in 2008. He later gained his PhD from the Centre for Process Integration (CPI), The University of Manchester in 2011. Kok Siew has industrial experience as a consultant in Process Integration Limited, UK, 2011-2013. He has involved in a diverse range of consultancy projects in the UK, Europe and China including refrigeration system for LNG processes, upgrading of gasoline feedstock into chemicals, water system integration in refinery and steel plant. He had also taken up a lead role in an EU-funded project on water system in steel plant. Kok Siew's expertise lies predominantly in conceptual process design, process integration, simulation modelling, techno-economic analysis and optimisation.
Kok Siew is the co-author of the advanced engineering textbook, “Biorefineries and Chemical Processes: Design, Integration and Sustainability Analysis”, published by Wiley in 2014. He was awarded the IChemE Junior Moulton Medal in 2011 for the best publication for his work on clean coal technologies.

Topics covered include:
Introduction: An introduction to the concept and development of biorefineries.
Tools: Included here are the methods for detailed economic and environmental impact analyses; combined economic value and environmental impact analysis; life cycle assessment (LCA); multi-criteria analysis; heat integration and utility system design; mathematical programming based optimization and genetic algorithms.
Process synthesis and design: Focuses on modern unit operations and innovative process flowsheets. Discusses thermochemical and biochemical processing of biomass, production of chemicals and polymers from biomass, and processes for carbon dioxide capture.
Biorefinery systems: Presents biorefinery process synthesis using whole system analysis. Discusses bio-oil and algae biorefineries, integrated fuel cells and renewables, and heterogeneous catalytic reactors.
Companion website: Four case studies, additional exercises and examples are available online, together with three supplementary chapters which address waste and emission minimization, energy storage and control systems, and the optimization and reuse of water.
This textbook is designed to bridge a gap between engineering design and sustainability assessment, for advanced students and practicing process designers and engineers.
