CEP: Editorial - Harnessing Our Abilities

October
2014
Editorial
Cynthia Mascone
We all have limits to our abilities. Some of us stumble over our words and lose our train of thought when speaking to a group; others can’t string together three coherent sentences. Some of us get so bogged down in minutiae that we lose sight of the big picture; others are so busy dreaming up the next project that we neglect important details and miss deadlines. This thinking extends to physical characteristics. Some of us are so short that we can’t reach the second shelf in the cabinet; others are so tall that we can’t fit into the backseat of a car.

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.

Catalyzing Commercialization: Greening the Packaging Industry

September
2014
Catalyzing Commercialization
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.

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: Catalyzing Commercialization - An Elegant Design Makes Compressed Air a Contender for Grid-Scale Storage

August
2014
Catalyzing Commercialization
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.

CEP: AIChE Journal Highlight - An Inverse Approach to Materials Discovery and Design

August
2014
Journal Highlight
The success of many emerging technologies hinges on the discovery of new materials that exhibit a combination of desired properties. Identification, synthesis, and fabrication of suitable materials for these applications remain challenging, relying on resource-intensive exploratory science. A better approach might be to begin with the target macroscopic properties in mind and then systematically narrow the list of possible material precursors and synthetic methods through an optimization technique.

CEP: Spotlight on Safety - Be Prepared, Be Safe, and Have Fun

August
2014
Spotlight on Safety
Louisa Nara
One of my favorite warm weather activities is kayaking. The river provides a respite away from crowds and electronic distractions. Daily stressors are erased by the warm sun, a light breeze, and the sound of water lapping at my boat. A recent weekend with great weather afforded the perfect opportunity to go out on the river with my husband. Earlier that week, severe storms blew through the area with significant rainfall and flash flooding. This increased the volume of water in the river, so conditions would be perfect for a fast and exciting ride. It also called for a more-mindful approach to safety hazards, like swift currents and debris in the water.

CEP: Editorial - Get Smart about Electricity

August
2014
Editorial
Cynthia Mascone
According to the Edison Foundation, nearly 40% of U.S. households, about 46 million residences, are outfitted with a smart meter for monitoring and managing electricity use. Some of these meters operate under direct load control (DLC), which allows the utility to intermittently interrupt service to connected appliances — such as electric heaters, central air conditioning systems, water heaters, hot tubs, and clothes dryer heating elements — during periods of peak electricity demand. In return for their willingness to accept these short (typically no more than a few hours) power interruptions, customers receive a payment or a credit on their electric bill. Smart metering is a form of demand-side management, and is an important part of the evolving smart grid.

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.

CEP: Editorial - Take a Hike

Cynthia Mascone
Although I recently returned from a vacation and would love to tell you about the hiking we did, that’s not the topic of this editorial. Previously, I wrote about jump-starting creativity through relaxation and trying something new (Dec. 2013) and by incorporating play into your day (Jan. 2014). Here’s another powerful creativity booster to add to your toolbox — walking. Your walk doesn’t have to be an eight-mile trek from the Colorado River at the bottom of the Grand Canyon to the rim nearly a mile higher. Walking can be as simple as doing laps around the office, or getting off the bus or train a stop or two early and walking the rest of the way to your destination.

Process Safety Beacon
Some process safety incidents have occurred because operating personnel failed to recognize that a process was not responding as expected. They attempted to keep a process in operation by deviating from standard procedures, or put themselves in danger by attempting to correct an out-of-control process condition rather than evacuating.

CEP: Patent Update - Do You Qualify as a Co-Inventor?

July
2014
Patent Update
M. Henry Heines
Co-inventorship on a patent provides several advantages to an individual, but a proper listing of inventors is both critical to the patent’s validity and can be challenged at any time. A recent case involving a General Electric patent illustrates some of the requirements of a co-inventor and the hurdles that an individual can face when asserting co-inventorship status after a patent has been issued.
