Robust control can be applied to design controllers that can handle process uncertainty. Learn how to use identification experiments to obtain estimates of this uncertainty.
The challenges facing the world today — including climate change, resource scarcity, food security, water access, and energy demand — are fundamentally different than those of the past. These sustainability issues can be thought of as “wicked” problems — a concept that originated in the 1970s to describe the difficult challenges facing urban planners at the time and that has now spread to other areas, including engineering. In contrast with so-called tame problems, which can be solved by traditional linear, analytical approaches, wicked problems are much more intractable and very difficult to solve.

Thirty years ago — just after midnight on Dec. 3, 1984 — a pesticide plant in Bhopal, India, released approximately 40 tons of highly toxic methyl isocyanate (MIC) into the atmosphere. There were thousands of fatalities, hundreds of thousands of injuries, as well as long term health, environmental, and economic impacts. This incident is widely considered to be the worst industrial disaster in history.

The dynamic behavior of your process can never be modeled perfectly. However, process controllers can be designed to handle this so-called uncertainty.
In August 2014, the U.S. Chemical Safety and Hazard Investigation Board (CSB) reported the results of an investigation into a December 2010 explosion in a titanium and zirconium scrap-metal processing facility in West Virginia. The explosion caused three fatalities and one injury. Here is a brief summary of what is believed to have happened.
Today’s modern lifestyle demands highly functional products — from water-wicking fabrics and age-defying beauty products to patient-specific medicines and high-tech electronics — many of which rely on polymers. In turn, to meet these demands, manufacturers are asking for the ability to design and produce polymers with precise control over composition and architecture. Such sophisticated control, however, is not possible with the dominant incumbent technology, free-radical polymerization. Thanks to a process developed by Carnegie Mellon Univ. spin-out ATRP Solutions, creating the perfect polymer with exactly the right composition, size, and shape just got much easier.
Many industrial plants currently operating around the world have already surpassed their design life expectancies. Despite the challenges they face, such as corrosion and new regulations, these operations continue to be productive. To maintain the status quo and continue operation, plant managers need to keep a watchful eye on every aspect of the facility, from inspection and maintenance programs to the bottom line. Of course, plant safety and the environment, both of which can rise to the top of an aging plant’s list of concerns, are always on their minds.
The ability to control chemical reactions to efficiently and selectively produce the desired products has vastly improved over the past decades, with increasingly sophisticated techniques now available to dictate the outcome of these reactions. While much progress has been made, much more is needed to realize a perfect reactor, which would allow for full control of chemical transformations at the molecular level. In the October AIChE Journal Perspective article, “Practical Challenges in Energy-Based Control of Molecular Transformations in Chemical Reactors,” Andrzej Stankiewicz, Izabela Szydłowska Franssen, Daniel Irimia, and Georgios Stefanidis of Delft Univ. of Technology expand on this topic of molecular control in chemical reactors.

Hazard identification and risk analysis (HIRA) includes all activities involved in identifying hazards in your process, understanding potential incident scenarios, identifying safeguards, and evaluating risk to people, the environment, property, and business.
Many of us were taught that communicating a message is a three-step process. First, “you tell them what you’re gonna tell them.” Second, “you tell them.” Third, “you tell them what you told them.” A message relevant to chemical engineers that urgently needs delivering is this: The U.S. chemicals industry is re-emerging as a world-class dynamo with the potential to propel U.S. manufacturing to world-class status and, with it, the U.S. economy. The ultimate outcome of this is economic opportunity for our children and grandchildren.
Globalization has changed the landscape of global manufacturing and supply chains, creating huge opportunities for more efficient production of goods and services, but also significant sustainability issues. One such challenge is the waste of packaging materials throughout the supply chain. Northern Technologies International Corp. (NTIC), a small business headquartered in Circle Pines, MN, has developed bio-degradable, compostable, and, for the first time, bio-based, polylactide (PLA) for blown plastic packaging films and end products.
Engineering processes, operating units, and equipment are designed with clear objectives and usually operated under well-controlled circumstances as designed. However, for emerging situations that are not factored into the design, data become indispensable assets in decision-making for safe and efficient operations. In the September AIChE Journal Perspective article, “Process Data Analytics in the Era of Big Data,” S. Joe Qin, who is on leave from the Dept. of Chemical Engineering and Materials Science at the Univ. of Southern California, Los Angeles to work at the Chinese Univ. of Hong Kong, Shenzhen, demonstrates how data have been effectively used in process operations and control. He also provides new perspectives on how chemical process systems might evolve to a new paradigm of data-enhanced operations and control.

Most computer interfaces today take very little advantage of our sense of touch,” says James Patten, founder of the Patten Studio and inventor of futuristic user interfaces and interactive experiences. His work combines the principles of engineering, computer programming, and design to give users completely unique experiences — from creating their own chemical reactions by grabbing onto virtual elements in a periodic table, to folding a protein and having the computer physically resist the folding pattern.
The potential for the integration of large amounts of renewable energy sources with the electricity grid will require large-scale storage devices. Compressed-air energy storage (CAES) is a cost-effective option for multi-hour storage applications. SustainX, a venture-capital-backed spin-out of Dartmouth College’s Thayer School of Engineering, has developed a novel isothermal CAES technology that promises to eliminate the disadvantages of traditional CAES.
