CEP: Process Safety Beacon - Conduct of Operations

June
2015
Process Safety Beacon
Conduct of operations can be summarized in two simple concepts: (1) Say what you intend to do (procedures). (2) Always do what you say. This means, for example, that if your operating procedures say to shut down if a critical safety parameter exceeds a specified value, you must always shut down.

For many of us, having to negotiate for anything can be akin to driving a notoriously congested, pothole-filled highway in rush-hour traffic. We know it is not for the inexperienced or faint-hearted and therefore approach it expecting the worst possible outcome.

CEP: Profile -Christina Borgese: Building Entrepreneurial Excellence

June

Profile
“I see myself becoming the entrepreneurial chemical engineer,” says Christina Borgese, Director of Engineering and Development at PreProcess, Inc., a consulting company that she co-founded. Her company helps entrepreneurs commercialize their novel technologies by applying chemical engineering know-how and recruiting experts from around the world. “Creating new products, harboring new ideas — that excites me,” she says. “You never know who is calling next, or what new project you will be working on that nobody has ever done before.”

CEP: AIChE Journal Highlight - New Model Optimizes Water Use in Shale Gas Development

June
2015
Journal Highlight
In the June AIChE Journal cover story, “Investment Optimization Model for Freshwater Acquisition and Wastewater Handling in Shale Gas Production,” Linlin Yang, Ignacio E. Grossmann, and Meagan Mauter of Carnegie Mellon Univ., and Robert Dilmore of the National Energy Technology Laboratory, discuss a new mixed-integer linear programming (MILP) model to optimize water use in the hydraulic fracturing of shale gas in the Marcellus and Utica shale plays. The objective of the model is to minimize the capital and operating costs and maximize profit.

CEP: Process Automation Corner – The U.S. Chemicals Industry in Perspective

June
2015
Process Automation Corner
Terrence McMahon
If the U.S. economy were a professional sports league, the chemicals industry would be a franchise player. A healthy economy needs a core of financially strong, internationally competitive industries making products that can be sold in any geographic market. These industries provide highly compensated employment opportunities, which in turn creates flourishing communities and intellectual capital potential. Improved production processes and higher-quality products do not develop in a vacuum, but rather in the context of solving day-to-day production problems. Without domestic manufacturing, these opportunities are lost. Franchise industries are also export machines. This last quality is vital to a healthy economy — chronic trade deficits are a harbinger of decline.

CEP: Catalyzing Commercialization - High-Performance MOFs Improve the Economics of Industrial Gases

June
2015
Catalyzing Commercialization
The highly commoditized industrial gas sector relies on energy-intensive processes to produce, separate, and store industrial gases. The power required to compress gases accounts for up to 50% of the cost of the delivered gas. And, gas-separation adsorption units recover only a fraction of the feed product, necessitating processes with large waste or recycle streams. NuMat Technologies, an Illinois startup has developed synthetic adsorbent materials to address these challenges.

CEP: Commentary - Educating Students to Become Engineers

June
2014
Commentary
R Russell Rhinehart
The article “How Well Are We Preparing ChE Students for Industry?” in the Update section of the April issue of CEP (pp. 4–5, 14–15) meshed with my career-long concern about engineering education. I graduated in 1968, with pride in my skills, from “a strong program” that “was about to break into the top ten,” as we were told. It was a good program in many ways, but after two years in industry, I came to realize the misdirected perspectives I had acquired as a student. After 13 years in industry and 28 in academia, I have concluded that neither the academic perception of excellence nor the tasks students are required to complete align with the perceptions and tasks that lead to success in industry.

CEP: Career Corner - Is Starting a Consulting Practice Right for You?

June
2014
Career Corner
Loraine Kasprzak
Are you considering starting your own engineering consulting practice? One of my best career moves was leaving my corporate position to open my own consulting firm. Perhaps, like me, you were bitten by the entrepreneurial bug, or perhaps your current employer is downsizing and a severance package will provide you with the opportunity you have been waiting for — not to mention the cash reserves you need to get through your first year. Consulting may seem like a glamorous career, one in which you get to work when you want and make lots of money. Nothing could be further from the truth. You must be able to work without having the structure and accountability that being employed by someone else provides.

CEP: Editorial - Getting ChE Education Right — Part 2

June

Editorial
Cynthia Mascone
Our discussion of chemical engineering education began in the April issue, with the news story “How Well Are We Preparing ChE Students for Industry?” and my editorial, “Getting ChE Education Right.” This month, we look at education again, with two more articles. The April articles resonated with Russ Rhinehart, a professor at Oklahoma State Univ., and inspired him to write a letter to the editor, which became this issue’s Commentary, “Educating Students to Become Engineers” (pp. 14–15). By coincidence, the AIChE Journal Highlight, “A Broader Role for the Evolving Engineer” (p. 13), also focuses on education.

Energy is a very important factor in process automation. Improvements in energy efficiency gained through process automation played a key role in justifying the pioneering automation projects of the early 1960s and have grown in stature over the ensuing decades. Automation-enabled improvements in energy usage have made critical contributions to worldwide prosperity over the last 35–40 years.

CEP: Profile - Manu Prakash: Encouraging Curiosity-Driven Science

June
2014
Profile
One of the biggest hurdles to treating disease in developing countries is the lack of portable and cheap diagnostic instruments, such as microscopes. Manu Prakash, an assistant professor in the Dept. of Bioengineering at Stanford Univ., believes that frugal science is the key to enhancing global health and science education. Prakash is creating simple, economical tools to pique interest in science exploration and even perform field-testing for specific diseases, such as malaria. One such invention, the Foldscope, is a completely functional microscope that merges the principles of origami and optical design.

CEP: Catalyzing Commercialization - Ionic Liquids Charge Ahead as Battery Electrolytes

June
2014
Catalyzing Commercialization
Advances in energy-storage devices are a must for the widespread use of electric and hybrid vehicles, the integration of renewable energy with the electric power grid, and the development of smaller, faster, more-powerful consumer electronics. While progress has been made, several challenges remain, including limitations of nonaqueous electrolytes, which have poor transport properties and are highly flammable. The answer to this challenge: A new class of higher-performance electr-olytes being developed by Boulder Ionics Corp. (BI) for longer-lived, safer batteries and ultracapacitors.
