CEP: Process Safety Beacon - What Is the Process Risk?

January
2015
Process Safety Beacon
The worst process incident that can happen in your plant may not be the same as the highest process risk. Risk is a combination of how likely an incident is and how bad the consequences could be. The process incident in your plant with the worst consequences may be very unlikely to occur. Other less-severe incidents may be more likely, making the risk of these events higher than the incident with the worst consequences. You should be aware of all process risks in your plant, and your role in managing all of them.

CEP: YPOV - Engineering Your Job Change through Networking

January
2015
YPOV
Sarah Ewing
In the current job market, people rarely stay employed with the same company that hired them after college for their entire career. If you want to take control of your career and make a job change that is consistent with your professional and personal goals, allow enough time to weigh the pros and cons instead of making the decision on a whim. The most critical step in this process is not updating your resumé, but making sure that the new position will be a good fit and not just a quick fix. I like to think of changing jobs as a process with four key steps: recognizing that it is time to move on, deciding where you want to go, determining what you need to get there, and then networking your way in.

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: 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.

Process Safety Beacon
Corrosion under insulation (CUI) is corrosion of piping, tanks, or other equipment that occurs due to water under insulation or fireproofing. Faulty or damaged insulation is frequently a source of the water that causes corrosion, and the insulation may also hide the damage so you are not aware of it.
