Valappil, Jaleel V.
Jaleel V. Valappil is a senior engineering specialist with Bechtel Oil, Gas & Chemicals in Houston, TX, USA. He has several years of experience in process simulation, advanced process control and optimization of various processes including LNG. Before joining Bechtel, he was a senior consulting engineer with the Advanced Control Services Group of Aspen Technology Inc., where he was responsible for developing and implementing advanced control and optimization solutions for a variety of processes. He has worked extensively on developing and deploying process simulation models for applications in design, engineering, and operations of LNG plant built by Bechtel in collaboration with Conoco Phillips over the years. He identified the benefits of lifecycle modeling for LNG plants and its use for plant design, operability/controllability studies, startup simulations and Operator Training Simulators, multi-train LNG facility debottlenecking and operational troubleshooting. Dr. Valappil has also developed and deployed Advanced Process Control technology for LNG processes, for plants in engineering stage and plants that are already operating. He has published several papers on LNG plant simulation and control in both industry conferences and journals and holds patents related to LNG plant control and turbo-machinery operation.
Wood, David A.
David A. Wood has more than forty years of international gas, oil, and broader energy experience since gaining his Ph.D. in geosciences from Imperial College London in the 1970s. His expertise covers multiple fields including subsurface geoscience and engineering relating to oil and gas exploration and production, energy supply chain technologies, and efficiencies. For the past two decades, David has worked as an independent international consultant, researcher, training provider, and expert witness. He has published an extensive body of work on geoscience, engineering, energy, and machine learning topics. He currently consults and conducts research on a variety of technical and commercial aspects of energy and environmental issues through his consultancy, DWA Energy Limited. He has extensive editorial experience as a founding editor of Elsevier's Journal of Natural Gas Science & Engineering in 2008/9 then serving as Editor-in-Chief from 2013 to 2016. He is currently Co-Editor-in-Chief of Advances in Geo-Energy Research.
Mak, John Y.
John Y. Mak is a Senior Fellow and Technical Director at Fluor, the United States, and leads the technology and design development for Fluor chemical and energy division. He is the technical expert and SME with Fluor for over 40 years and has been leading major oil and gas, petrochemical and refinery projects from conceptual designs, feasibility studies, FEED development, detailed engineering, to plant start-up and performance testing. John has made contributions to innovations in natural gas treating and processing, NGL recovery, LNG liquefaction and regasification, synthesis gas purification, and carbon capture methods. John is the co-author of the Handbook of Liquefied Natural Gas, first edition (2013) published by Elsevier, the United States. He has published over 80 technical papers and has frequently presented his findings at technical conferences such as GPA Midstream Convention, GPA Europe, Laurance Reid Gas Conditioning Conference, LNG Summit, Offshore Technology Conference, GASTECH, and China Coal Forum. John is the inventor of over 90 patents and patent pending processes. John is specializing in more complex NGL recovery designs for conventional and unconventional gases, treating high CO2 content gases using physical solvents, acid gas removal with amines, cryogenic nitrogen rejection and helium recovery.
