University of Kansas testing new environmentally friendly refrigerant in Watson Library
The University of Kansas is testing a new environmentally friendly refrigerant in a Watson Library air-conditioning chiller. Built in 1924, Watson Library is the oldest and largest of KU’s libraries. The library has two York chillers that operate on refrigerant HFC-134a. The American Innovation and Manufacturing (AIM) act requires the production and use of hydrofluorocarbon (HFC) refrigerants in the U.S. to be phased down by 85% over the next 15 years. The global reduction in HFCs is expected to avoid up to 0.5 °C in global temperature rise. Foundation Distinguished Professor Mark B. Shiflett in the Department of Chemical and Petroleum Engineering is leading a research effort to develop new technology for efficiently recycling and repurposing HFC refrigerants called Project EARTH. Professor Shiflett working with the Chemours Company, Johnson Controls, Inc. (JCI), and KU facilities retrofitted one of the two York chillers to a new environmentally-friendly replacement for HFC-134a called Opteon™ XP10 (R-513A), which is a non-ozone depleting, low-global warming hydrofluoroolefin (HFO) refrigerant. R-513A has a 56% reduction in global warming potential (GWP) compared with HFC-134a and is compatible with existing equipment designs. Professor Shiflett stated, “We are grateful to Chemours who donated the refrigerant and JCI who provided the labor for this first side by side comparison of R-513A and HFC-134a in two 900-ton York commercial-scale chillers. Mechanical engineering seniors as part of their Capstone senior design course monitored the baseline performance of HFC-134a. A chemical engineering graduate student will monitor the cooling capacity and energy efficiency of R-513A this summer and we are expecting the performance to be equivalent to HFC-134a. This is a great example of how industry is partnering with our new Institute for Sustainable Engineering at KU (https://ise.ku.edu), which is making a positive impact on our environment.”
Work done in the Shiflett Research Group has recently been featured on 5 different journal covers, including the AICHE Journal, I&EC Research, ACS Sustainable Chemistry and Research, and the Langmuir Journal. To learn more about these features, visit the Journal Covers tab!

Prof. Mark Shiflett and Prof. Aaron Scurto were recently awarded a $2,000,000 Emerging Frontiers in Research and Innovation (EFRI) grant to study the separation and recycling of high global warming potential (GWP) refrigerant mixtures. Project EARTH (Environmentally Applied Research Towards Hydrofluorocarbon) will use a combination of experiments, advanced computer simulations, and rigorous analytical methods to discover, synthesize, and test ionic liquids that are efficient at separating azeotropic hydrofluorocarbon (HFC) mixtures. The research will be conducted by a team of researchers located at the University of Kansas (lead institution), the University of Notre Dame, Texas A&M University, and Rutgers University in collaboration with Brookhaven National Lab, Oak Ridge National Lab and the National Institute of Standards and Technology along with two industry partners (Chemours and Iolitec). The technical, economic, and environmental impacts of Project EARTH is immense, given the millions of kilograms of high GWP refrigerants that must be removed from the market. The market for recycling refrigerants is valued at more than a billion dollars and preventing the release of high-GWP refrigerants into the Earth’s atmosphere is equivalent to eliminating 175 million metric tons of CO2 (or annual emissions from 50 million cars).

Shiflett Research Group featured in KU News
A $1 million gift from University of Kansas alumni Richard and Elizabeth Hoover of Northport, Michigan, will establish a chemical engineering research lab at KU’s School of Engineering.
Mark Shiflett, Foundation Distinguished Professor in the Department of Chemical & Petroleum Engineering at KU, said being able to build laboratories such as the one supported by the Hoovers resonates with businesses that visit KU.
“Multibillion-dollar companies see these facilities, and they are really impressed. Companies such as DuPont and Chemours could go anywhere in the world to do research, and they come right here, to Kansas, working with us, and that offers tremendous opportunities to students,” Shiflett said. “And when projects we’ve worked on together are completed, these companies hire our students.”

Shiflett Lab Group Hosts Open House
Shiflett lab group hosted an open lab afternoon on April 28. The event featured undergraduate research presentations on their different projects from this semester. Dr. Shiflett and our post doctorate researchers also gave visitors tours of the lab space.
New Kinetics Experiment for Undergraduate Chemical Engineering Laboratory
Dr. David Griffin, Dr. Bill Gilbert and Prof. Mark B. Shiflett
A new kinetics experiment was completed and added to the undergraduate chemical engineering teaching laboratory for the Chemical Engineering Laboratory I, C&PE 616. Students can measure the kinetic orders and activation energy for the iodination of acetone reaction (CH3COCH3 + I2 → CH3COCH2I + HI) using HCl as a catalyst.
The reaction is a color change reaction so it starts as a colored solution when iodine is added (I2 is red/brown in color) and goes clear as the product iodoacetone is formed (iodoacetone is clear). The experimental setup consists of a 1 liter stirred tank reactor with a cooling/heating jacket controlled with a Peltier temperature bath. A pump circulates a sample of the reactor fluid through a flow cell in a spectrometer for instantaneous analysis of the iodine concentration as a function of time. The temperature and absorbance are recorded using a LabView® data acquisition program on a laptop computer. The waste can be drained to waste containers beneath the reactor and the system is mounted on a moveable rack which allows the experiment to be portable. The setup is identical on both sides of the rack so that students can work in groups of two to run both reactors simultaneously. The spectrometer measures the absorbance of iodine at a wavelength of 510 nm. Students use both a linear regression (Initial Rates Method) and a non-linear regression to analyze the kinetics data to determine the orders of reaction and the activation energy. In addition to the experiments, students model the reaction using Aspen Plus using both batch (RBATCH) and continuous (RCSTR) reactor models. The fact that the experiment is portable allows the equipment to be wheeled into the classroom for demonstration during lectures. Students taking Chemical Kinetics C&PE 524 will learn how the experiment works, the methods for data analysis and be assigned a homework set based on actually experimental data being measured by the Senior class. This will connect the lab course with the kinetics course and familiarize the Juniors in C&PE 524 with the kinetics experiment they will do the following semester in the undergraduate laboratory course C&PE 616. In addition, future experiments can be conducted with other reactants such as bromine and the effect of different catalysts can be studied.
A new thermodynamics experiment is planned for construction during the summer of 2017 and ready for use in C&PE 616 by the Fall semester. The intent is by the Fall of 2018, that three new experiments focused on kinetics (complete), thermodynamics and fluid mechanics will be ready which connect the theory taught in the core courses with the laboratory course. The experiments will be portable and allow instructors to describe the experiments in the classroom and build homework sets based on data measured by students to familiarize Juniors with the Senior laboratory equipment and analysis methods.
