A new topical conference devoted to the hot topic of shale gas and tight oil, special programs spotlighting the progress made within the process safety community, and a new luncheon are just a few of the opportunities to learn and collaborate at AIChE’s 2014 Spring Meeting and 10th Global Congress on Process Safety (GCPS).
Projects aimed at improving distillation column operation may encounter a variety of hurdles. This article looks at ten common problems and provides guidance on how to avoid them.
As the Director of Discipline Capability within BP’s Global Wells Organization, a private pilot, and mother, Kelli Fereday has demonstrated that an adventurous, rigorous career and strong family life are not mutually exclusive. Fereday has spent nearly 20 years with BP, cultivating a stimulating and challenging livelihood, and championing female engineers — especially those who have or want a family — by encouraging them to take control of their careers.

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.”

Cold traps — steam traps that no longer drain condensate — are often ignored in lieu of less-critical leaking traps, until a catastrophic event, such as a plant shutdown or personal injury, occurs. Use historical data to accurately estimate the annual cost of these cold traps to justify their swift repair.
Pipes and equipment that are not properly supported will be subject to stress, vibration, or other problems, This can cause leaks, or even a complete collapse of piping or equipment. But, problems with inadequate support of piping and other...
