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.
What does it take to attain great process safety performance? How do you “get it,” or where do you “find it”? How do you instill that desire in others?
From fermentation to gene splicing to the sequencing of the human genome, the field of biochemical engineering and the career of Professor Daniel I. C. Wang have followed similar paths. Here we trace the route they have taken.

Although relief devices may never be activated, they must be designed and sized to function correctly every time they are necessary. This article provides an introduction to sizing pressure-relief devices for liquid and vapor service.
The ability to exploit a cell’s contents and capabilities unimpeded by cell walls opens new opportunities for the field of biochemical engineering. Cell-free biology could become the basis for making products from hydrogen to cancer vaccines and more.
A poll conducted by the Univ. of Texas at Austin ( www.utenergypoll.com/newsroom ) in September found that the average American does not have a good understanding of energy issues. What’s saddening is that many don’t seem to care much about energy...

And living with them isn’t always easy, either. Two experiences drove the latter point home to me recently. As we were working on this issue with its special section on lithium-ion batteries, both of my laptop’s batteries — the main battery that...
One hundred years ago, on Oct. 14, 1913, the Senghenydd Colliery in Glamorgan, South Wales, exploded, resulting in 439 fatalities. This was the worst coal mine disaster in the history of the U.K. The incident is believed to have been started by...
The materials used in the construction of a battery’s components must be chosen carefully to optimize battery performance for the speciﬁc application.
As chemical processing plants and related facilities age, they typically develop problems with corrosion. Allowing deterioration to progress until a piece of equipment needs to be discarded and replaced — called the “run to failure” option — can be...

Air is always all around us, and the oxygen it contains is necessary for life. But, compressed air (or any other compressed gas) contains a lot of energy and can cause major damage if a vessel or pipe fails.
Chemical engineering as it is known today — in which theoretical models are used to design and maintain processes — bears only a slight resemblance to the nascent field. In its beginnings, chemical engineering involved the dissection of chemical processes into unit processes and unit operations using mostly empirical methods. Material and energy balances soon entered the scene in the late 1920s, followed by the introduction of transport phenomena. While many scientists and engineers contributed to the evolution of chemical engineering, one man in particular stands out. Neal Russell Amundson, who became a full professor of chemical engineering at the Univ. of Minnesota at the age of 35, can be credited for the proliferation of scientific content within the chemical engineering field and profession.

Chemical engineers and sound engineering principles have been absent from the discussions of global challenges — energy, climate change, food, and water — for too long, assert Bill Banholzer and Mark Jones of Dow Chemical in their August AIChE Journal Perspective article, “Chemical Engineers Must Focus on Practical Solutions.” Society has thus confused what is possible with what is practical, particularly when it comes to energy, where new discoveries are greeted with over-excitement and the hope that each will provide the means to supply reliable, cheap, and almost-limitless energy, the authors say. They cite the hydrogen economy, cellulosic ethanol, and fuel cells as examples of technologies that have promised much but delivered little
Countless books and articles have been written about leadership — on such topics as the differences between managing and leading, what makes a good leader, and how to become a better leader, among others. One frequent topic: Are leaders born or made? The Center for Creative Leadership (CCL) posed this question to C-level executives of companies in 53 countries ( www.ccl.org/leadership/pdf/research/areleadersbornormade.pdf ). Slightly more than half (53.4%) of the top executives think leaders are made, about a fifth (19.1%) think they are born, and a little more than a quarter (28.5%) think leaders are both born and made.
