CEP: Catalyzing Commercialization - Turning a Problem into a Cure for Increased Ethanol Yield

January
2014
Catalyzing Commercialization
The beneficial microbes that convert milk into yogurt and act in our guts to promote digestive health cause big problems in ethanol fermentation tanks. These lactic acid bacteria (LAB) proliferate in ethanol feedstock and inhibit growth of ethanol-producing yeast — which slows down fermentation, reduces biofuel yield by as much as 20% per pound of input material, and results in production shutdowns due to contamination. The most common control measures, chemical antimicrobials such as antibiotics, do not eliminate LAB. Additionally, the potential for antibiotic residue limits the marketability of dried distillers grains, a byproduct of the fermentation process used as animal feed. Ecolyse Inc., based in College Station, TX, is working to address this issue by developing products to treat bacterial contamination.

CEP: Process Automation Corner - The U.S. Process Automation Enterprise Looks to the Future

March
2014
Process Automation Corner
Terry McMahon
The outlook is bright for the process automation enterprise in the U.S. through this decade and into the next. Process automation skills and know-how are honed through challenging projects and are perfected by maintaining these systems at peak efficiency. Without constant renewal based on new and different challenges, these skills tend to atrophy and become obsolete. Fortunately, after more than a decade of decline, the U.S. process industries are entering a period of highly advantaged resource and energy availability.

CEP: Catalyzing Commercialization - Zero-Emissions Magnesium Process Debuts

March
2014
Catalyzing Commercialization
A process designed to lower the cost of magnesium metal, making it competitive with aluminum, has been an industry goal for over a century. Although magnesium metal makes up millions of today’s lightweight cell phone and laptop cases, its persistently high cost (twice that of aluminum today) has impeded broad, high-volume use in other areas, including the automobile industry. This could soon change, thanks to researchers at INFINIUM, based in Natick, MA, who have developed a low-cost, energy-efficient, zero-emissions process for making this lightweight, strong metal.

CEP: Patent Update - An On-Sale Bar to Patentability Can Arise in Various Ways

February
2014
Patent Update
M. Henry Heines
One of the ways in which companies often trip up in their attempts to develop a patent portfolio is by selling a product, or even offering it for sale, before filing a patent application. If more than a year passes between the date of a sale or offer and the application filing date, the application is disqualified from receiving a patent. Likewise, if a sale or offer a year before the filing date is revealed only after the patent has been granted, the patent is declared invalid. In either case, the applicant is barred from obtaining a patent, and this is known as an “on-sale bar.”

CEP: AIChE Journal Highlight - Casting Process Safety as a Control Problem

January
2014
Journal Highlight
Process safety has come a long way since the Bhopal tragedy in 1984. However, accidents in the chemical process industries continue to occur. Post-mortem analysis has indicated that many were preventable and had similar systemic causes. This begs the question: Why do we fail to learn from past events and make adequate changes to prevent their recurrence? In the January AIChE Journal Perspective article, “A System-Theoretic, Control-Inspired View and Approach to Process Safety,” Nancy G. Leveson and George Stephanopoulos of MIT offer their take on this question.

A worker was asked to move two open-top 5-gal pails containing aqueous sodium permanganate solution from one location to another. When he picked up the pails, the contents of one of them erupted, spraying him with the solution. Sodium permanganate is a strong oxidizer, and the splashed material set the worker’s clothing on fire. His injuries required hospital treatment.

CEP: Process Automation Corner - Real-Time Analytics for Pharmaceutical Quality Control

December

Process Automation Corner
Terry McMahon
When the U.S. Food and Drug Administration (FDA), under the leadership of Ajaz Hussain, then the Associate Director of the FDA’s Center for Drug Evaluation and Research (CDER), launched the Process Analytical Technology (PAT) Initiative a decade ago, it set in motion a multifaceted search for a more scientifically based approach to pharmaceutical manufacturing and quality assurance. Hussain’s call for more PAT in the industry’s manufacturing operations was really more of a challenge to current practices than a proscriptive program. The pharmaceutical industry has responded with a renewed emphasis on understanding the scientific basis of its processes, and toward that end has made significant investments in personnel and tools.

CEP: Process Safety Beacon - Holiday Operations

November
2013
Process Safety Beacon
Many plants shut down or reduce operations during a holiday period. Equipment may be in a non-standard condition while processes are on hold or shut down. Even though the plant is shut down, it is likely that hazardous materials are still present in storage tanks and process vessels. Equipment that is shut down may be opened for inspection or maintenance. Some plants continue to operate during a holiday but with reduced staff, delaying less-critical activities.
