CEP: September 2014 Some materials are more vulnerable to supply disruptions than others. This month's cover feature on critical materials introduces methods to identify at-risk critical materials, and outlines general strategies to address challenges related to these materials. Other article topics include: solid-fluid equilibrium modeling; DOE's Superior Energy Performance program; and identifying energy-saving process improvements. Editorial Elements of Fun Whenever I come across an interesting article or tidbit of information in the general media that I think might make a good topic for an editorial, I file it away. Then, each month when it’s time to write my editorial, I browse through those (paper and electronic) files to find anything that relates to what’s in the issue or what’s happening at AIChE.A few years ago, I came across Discover magazine’s “20 Things You Didn’t Know About … The Periodic Table,” and I knew it was a keeper. Surely, I thought, at some point I’ll be able to relate this to an article. Read more Share Manage Raw Material Supply Risks September2014Critical IssuesStephen Hung, Anthony Y. Ku Some materials are more vulnerable to supply disruptions than others. Identify these materials and implement strategies to address challenges related to them. Introduction to Solid-Fluid Equilibrium Modeling September2014Back To BasicsChau-Chyun Chen, Yifan Hao, Sheik TanveerThis article introduces the thermodynamic property models that are commonly used in process simulators to perform solid-liquid equilibrium and solid-supercritical fluid equilibrium calculations. Save Energy through the Superior Energy Performance Program September2014EnergyPaul ScheihingFacilities have improved their energy efficiency by implementing the ISO 50001 energy-management standard and participating in the U.S. Dept. of Energy’s SEP program. Here’s how your facility can earn SEP certification while reducing its energy use and saving money. Identify Process Improvements for Energy Efficiency September2014EnergyJoeseph L. Davis, Jr., Alan P. RossiterThe energy efficiency improvement potential of chemical processes is often overlooked. A process flow diagram review is the first step toward reducing your plant’s energy consumption. Copyright Permissions: Would you like to reuse content from CEP Magazine?
