Bhavesh (Bob) Patel, CEO and chairman of the management board of LyondellBasell, talks to CEP about his strategy for leading one of the largest plastics, chemicals, and refining companies in the world. In 2010–2011, faced with significant debt and soft demand, the company had to restructure and cut costs. Emerging from those dark times, LyondellBasell is now focused on growth and expanding its operations where it has a competitive advantage.

By separating a reaction into several subreactions, chemical looping minimizes exergy loss, facilitates product separation, and provides flexibility in process design.
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.

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.

Whether we are talking about occupational safety or process safety, normalizing a deviation can result in unsafe practices, conditions, and operations. Getting comfortable with and accepting these deviations can cause a shift in our perception of what is safe. Why does this matter? Moving the target for safe operating limits and tolerating the higher risk s associated with doing so can ultimately lead to a catastrophic incident.
More than 75% of the world's food testing continues to rely on 120-yr-old cell-culture methods, which take days to produce results. New technology developed by scientists at Rheonix Inc., based in Ithaca, NY, is enabling a portable unit that greatly simplifies the testing through automation, providing results in hours instead of days and reducing costs. Thermo Fisher Scientific Inc. has incorporated the Rheonix technology into a new generation of PCRbased rapid analysis for the food- and beverage-testing markets.
The familiar ring-shaped stain left behind after spilled coffee has dried represents a complex engineering problem involving principles of heat and mass transport, fluid mechanics, and surface phenomena (among others) whose solution has value well beyond spilled coffee, including the analysis of DNA microarrays, inkjet printing, and coating. In the May AIChE Journal review article, “Transport and Deposition Patterns in Drying Sessile Droplets,” Ronald Larson of the Univ. of Michigan examines this engineering problem — understanding the processes by which a liquid drop (containing nonvolatile solute or colloidal particles) on a surface evaporates and leaves behind the particles that form a stain.

Although corrosion resistance is of paramount importance, many factors must be considered when selecting materials of construction. Follow this four-step process to identify the appropriate material for your application.
We may think of process safety incidents as fires, explosions, and immediate injuries from exposure to toxic, corrosive, or otherwise hazardous materials. However, major spills of hazardous materials, especially into rivers or other bodies of water, are also process safety incidents. They have the potential to impact large numbers of people, including people far away from your plant.
