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 - Energy Cost Averaging

March
2015
Editorial
Cynthia Mascone
Last year, when we chose biofuels as the topic for this issue’s Society for Biological Engineering (SBE) supplement, we did not anticipate the precipitous drop in oil prices of recent months. As we were pulling the articles together, guest editor Mark Holtzapple expressed concern that oil prices would be low when the issue appears. “If readers do not think too deeply, they might say ‘These academics are sure out of touch. Don’t they know oil prices are low?’”

CEP: Spotlight on Safety - Verify, then Act

May
2015
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.

CEP: Editorial - Getting ChE Education Right — Part 2

June
2014
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.

Cynthia Mascone
When I was in college, I earned some spending money as a shoe model for a local freelance photographer. Little did I know I would become a cover girl. But a few years later, shortly after I began my career as an editor (at a different magazine), I was tapped for just that role. Wearing a black cap and gown and photographed looking out into a maze of piping in a chemical plant, I represented a young graduate facing my first job in industry. The cover line — “Chemical engineering education: How good is it, really?” — referred to an article that discussed the results of a reader survey conducted by two of my colleagues. That was 31 years ago. Today, we are still pondering the same question.

Here’s another powerful creativity booster to add to your toolbox — walking. Your walk doesn’t have to be an eight-mile trek from the Colorado River at the bottom of the Grand Canyon to the rim nearly a mile higher. Walking can be as simple as doing laps around the office, or getting off the bus or train a stop or two early and walking the rest of the way to your destination.

Culture can be defined as a collective group of shared beliefs and values that shape how we act. We think of culture as it relates to the actions and reactions of a group, company, or society. However, it can also characterize an individual — what influences how you make day-to-day decisions or handle various situations. Personal process safety culture can be assessed by observing someone’s (yours or another person’s) response to situations involving a safety violation.
