CEP: AIChE Journal Highlight - Solving Wicked Sustainability Problems Requires a New Approach

December
2014
Journal Highlight
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.

November
2014
Journal Highlight
The chemical engineering curriculum has changed over the years and will continue to change in the future. In the November AIChE Journal Perspective article, “Evolving Trends in Chemical Engineering Education,” Arvind Varma of Purdue Univ. and Ignacio Grossmann of Carnegie Mellon Univ. examine this evolution and illuminate the impacts of shifts in academic research and industry needs. Taking a close look at the history and likely course of chemical engineering education provides a basis for discussing whether this trajectory is heading in the right direction to meet the needs of industry and to address societal issues.

CEP: Process Safety Beacon - Bhopal – The Worst Industrial Disaster in History

December
2014
Process Safety Beacon
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.

CEP: Process Safety Beacon - An LPG Tragedy

November
2014
Process Safety Beacon
At about 5:30 a.m. on Nov. 19, 1984, there was a major fire and a series of explosions at a liquefied petroleum gas (LPG) storage and distribution terminal at San Juan Ixhuatepec, Mexico City, Mexico. There were over 500 fatalities, about 7,000 injuries, 200,000 people were evacuated, and the terminal was destroyed. The blasts were recorded on a seismometer 20 km (12.4 miles) away. Most of the injuries and fatalities were in the surrounding community — people were living as close as 130 m (425 ft) from the terminal. The cause of the accident could not be definitively established because of the destruction of the facilities and absence of witness reports.

CEP: Catalyzing Commercialization: Producing Tailor-Made Polymers at the Commercial Scale

October
2014
Catalyzing Commercialization
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.

CEP: Material Matters - Managing Aging Plants

Material Matters
Kirk Richardson
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.

CEP: Journal Highlight - A Path Toward the Perfect Chemical Reactor

October
2014
Journal Highlight
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.

CEP: AIChE Journal Highlight - How Big Data Analytics Will Revolutionize Chemical Manufacturing

September
2014
Journal Highlight
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.

CEP: Process Automation Corner - Communicating the Message of Economic Opportunity

September
2014
Process Automation Corner
Terry McMahon
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.
