CEP: AIChE Journal Highlight - Bridging the Scale Gap to Model Heterogeneous Catalytic Reactions

July
2015
Journal Highlight
To fully harness the advantages of heterogeneous catalysis, heat and mass transfer must be optimized with respect to catalytic reaction rates. While reactions take place at the molecular length scale, industrial reactors can have dimensions as large as several meters, making reactor and catalyst design a difficult task. In the July AIChE Journal cover story, “Gas-Solid Catalytic Reactions with an Extended DSMC Model,” Georg R. Pesch, Norbert Riefler, Udo Fritsching, Lucio Colombi Ciacchi, and Lutz Mädler of the Univ. of Bremen, Germany, introduce a new modeling approach to efficiently tackle this challenge.

The week before we send an issue to the printer can be both exhilarating and exhausting. So, I was intrigued by an article on scientificamerican.com, “Overworking Your Brain Can Spark Ideas,” which reported on research that found people generate the most creative ideas when they’re mentally exhausted. It never occurred to me that this might be an especially fruitful time for coming up with good ideas. I wondered how that research might apply to me, and whether it might suggest new ways to push the CEP staff even harder.

CEP: Catalyzing Commercialization - Designer Microbes Make Green Surfactants

July
2015
Catalyzing Commercialization
Surfactants are typically made from petroleum-based feedstock or palm oil — using processes that produce greenhouse gases, involve the use of toxic chemicals, and generate hazardous byproducts. Massachusetts-based biotech company Modular Genetics, Inc. has engineered Bacillus subtilis strains to convert cellulosic sugar into a surfactant consisting of a fatty acid linked to an amino acid. Its approach uses no oil of any sort or toxic chemicals, and the surfactants do not generate hazardous byproducts.

Process Safety Beacon
You cannot know when an unexpected reaction in a vessel might develop enough pressure to cause the vessel to rupture. All a large release of a flammable vapor needs in order to burn or explode is an ignition source. Never put yourself in danger by remaining in the area if this happens in your plant. Know your facility’s emergency plans, participate in drills, and know when to evacuate or shelter in a safe place.

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

June

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

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.

May

With a global production of 150 million metric tons in 2013, polyolefins represent the largest class of synthetic polymers. Today, the industry uses a costly, time-consuming, “one catalyst, one material” trial-and-error approach to developing new polymers. Precision Polyolefins (PPL) intends to change the status quo by establishing a novel “one catalyst, many materials” paradigm for rapid discovery and product development of new polyolefins.

CEP: Spotlight on Safety - Verify, then Act

May

Spotlight on Safety
Louisa Nara
Verify-then-act is a practice and mindset that all engineers and personnel in the chemical process industries (CPI) should adopt. Mixing the wrong chemicals, setting temperatures or pressures outside of safe operating limits, or performing a step out of sequence can result in a range of consequences, from a bad batch or loss of production to a catastrophic incident. However, simply verifying before acting can reduce the risk of these penalties and save time, money, and lives.

In the April AIChE Journal Perspective article, “Layer-by-Layer Approaches to Staging Medicine from Surfaces,” Paula T.

Each layer contains a different therapeutic, which is incorporated into the thin film via one of several mechanisms (e.g., charge, hydrogen bonding, or other complementary interaction). This technique is useful for drug therapy in applications such as bone regeneration.

In the article “Recognize Hazards to Recognize Change” (pp. 40–44), Donald Lorenzo, Della Wong, and Mark Suyama liken managing change in the chemical process industries (CPI) to the challenge of piloting a ship on a voyage. Subtle changes in winds, waves, currents, and tides are difficult to discern, but each small change becomes the new normal, and the next change seems to be only a small difference. Only after the ship hits an obstruction does the captain realize how severely the ship has veered off course. That was the inspiration for this issue’s cover.
