Programming for an AIChE conference — i.e., developing the technical program — takes a lot more than the work put in by the meeting chairs; the details and ideas that go into every session and its roster of speakers take a whole force of volunteers. As a co-chair for the upcoming 2014 Spring Meeting in New Orleans who also happens to be a young professional (YP), I’ve realized that the best way to prepare for programming a large-scale conference is to build relationships across all levels of the organization.
Organizers are putting the finishing touches on the schedule of events for AIChE’s 2014 Spring Meeting and 10th Global Congress on Process Safety (GCPS), to be held Mar. 30 – Apr. 3 at the Hilton New Orleans – Riverside, in New Orleans, LA.
Read about new products and services in the areas of fluids and solids handling, instrumentation, and materials and chemicals.
You’ve spent hours writing your paper, preparing the slides for your presentation, and practicing your talk. You’ve endured the humiliation of the airport security inspection, the frustration of the weather-related flight delay, the discomfort of the cramped airplane seats, and the disruption of your circadian rhythm after crossing several time zones. You arrive at the meeting room early, check your slides on the session chair’s laptop, get comfortable with the remote, and test the mic. You are excited to be part of this group of experts, and are looking forward to sharing your thoughts and engaging in a lively dialogue.
Use a phase diagram to identify the best temperature, pressure, and composition conditions, as well as the optimal sequence of process operations to achieve a desired crystallization.
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.

Existing equations used to size control valves are inadequate for laboratory- and pilot-scale work. Use the simple equation introduced in this article to accurately size needle control valves for laminar and transitional flow.

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.
The recent development of new sources of shale-gas methane and shale-gas condensate will significantly impact fuels and chemical feedstocks in the U.S. and around the world, says Jeffrey Siirola of Purdue Univ. and Carnegie Mellon Univ. in the March AIChE Journal Perspective article, “The Impact of Shale Gas in the Chemical Industry.”

Licensure as a professional engineer is an investment in your future, and can be a beneficial — and even necessary — credential.
To maintain favorable conditions in the brain, the blood-brain barrier limits mass transfer across brain tissue. However, it also restricts the systemic delivery of compounds to treat neurological disorders. Several treatment alternatives to bypass...
If you manage to stay afloat long enough, past associations inevitably resurface. At a recent Société de Chimie Industrielle luncheon, I reconnected with a client who I hadn’t seen in almost 30 years. In 1983, I was retained by an investment banker...
Lack of labeling can be a safety problem, and poor or confusing labels or information signs can be even worse.
To surpass the merely adequate, and to accomplish something noteworthy, requires one to take on tasks that are unstated and to solve problems that others may not have even noticed. Depending on the structure of your work environment, there may be...
Many of us remember receiving our polio vaccine on a sugar cube. Indeed, that was the motivation behind A Spoonful of Sugar, a song from the classic Disney movie Mary Poppins. Walt Disney had instructed the Sherman brothers, Robert and Richard, to come up with a catchy song for the film. When Robert arrived at home, after working all day trying to come up with an idea, his wife told him that the children had gotten their polio vaccine that day. Thinking they had gotten a shot, he asked them if it hurt. His son answered that the medicine was put on a cube of sugar and he swallowed it. And so “a spoonful of sugar helps the medicine go down was born.
