  1. Dr. Mingheng Li’s Senior Projects 2016 - 2017

  2. Highlights • All related to industrial energy systems and water desalination. • Focus on chemical engineering fundamentals and process design principles. • Use of industry-standard software packages including Aspen Plus, Pro/II, Matlab, ComsolMultiphysics and others.

  3. Project 1: Reverse Osmosis Membrane Desalination • We study fluid mechanics and mass transfer in commercial reverse osmosis modules used for drinking water production from groundwater and seawater. • We aim to shed insight into optimal design and operation of industrial reverse osmosis processes based on fundamental understanding obtained from this project.

  4. Project 2: Li-ion Battery State of Charge Estimation and Control • State of Charge (SoC) can not be measured directly when battery is in operation. However, it can be estimated by smart algorithms based on real-time current and voltage data readily available. • We implement and validate smart algorithms that can accurately estimate SoC in real-time, even if the initial guess is off.

  5. Project 3: Organic Rankine Cycle for Power Generation from Waste Heat • Organic Rankine cycle is similar to a steam cycle except that the working fluid is a refrigerant instead of steam. It works at relatively low temperatures, thus suitable for industrial waste heat recovery and geothermal applications. • We aim to address design and operation issues in this promising clean-energy technique.

  6. Project 4: Chemical Looping Combustion for Power Generation with Carbon Capture • It is based on Cu/CuO redox reaction to produce heat and power. It employs cyclic operation of two reactors. CO2 and N2 are naturally separated, which differs from a conventional combustion furnace. Fuel Reactor: 4CuO + CH4 = 4Cu +CO2 + 2H2O Air Reactor: 4Cu + 2(O2 + 4N2) = 4CuO + 8N2 • We aim to advance fundamental understanding of this low emission process and to shed insight into its design and operation.
