Small chemical reactors offer a number of benefits compared to large reactors, such as better heat transfer and mixing. While small batch vessels are impractical at the industrial scale, continuous flow reactors can provide the benefits of small physical size without the practical difficulties of multiple vessels. This article considers the four basic needs of flow reactors (volumetric capacity, heat...

Blending and segregation are two opposite and competing processes in solids handling that ideally fit the expression “two sides of the same coin.” But, if you think about it, coins have three sides and sampling completes the idiomatic expression perfectly. Blending is a necessary and essential process operation widely employed in many industries and materials, from nano-scale powders to...

Vacuum conditions for many unit operations — including distillation, evaporation, drying, crystallization, filtration and more — are typically achieved using the following three approaches: • Steam ejector systems • Mechanical vacuum pumps • Integrated vacuum systems (which combine steam ejectors and mechanical vacuum pumps) This article is the second part of a two-part series,1...

Increasing production of natural gas from hydraulic fracturing of shale deposits has fundamentally altered the landscape of chemical production in North America. The higher margins on steam-cracking ethane to produce ethylene have resulted in significant feedstock shifts in the U.S. over the past two years. Numerous chemical producers are expanding ethylene capacity to take advantage of the increased...

Reviewed by David Hill, Chemstations Inc., Houston   The authors of this text are leaders in chemical engineering thermodynamics. Based on their status, I recommended this book in a blog entry before even seeing a review copy — and I’m glad I did. The book is aimed at both students and professionals who work with process simulators. It assumes a prior understanding of thermodynamics, and...

Last month, we ran a letter from reader, Jason Makansi, commenting on our June story, Chemical Engineering Education Evolution ( Chem. Eng., June 2012, pp. 22–25), which highlighted, among other things, the need for a more-meaningful connection between academia and industry. Makansi’s letter was passionate in itself, expressing frustration at the slow pace of progress over the past 30 years or...

Contact agitated dryers are used for drying wet powders, slurries, filter cakes, and applications where off-gases during the drying cycle must be contained. If the applications are also heat-sensitive, such as specialty chemicals, polymers, food products and pharmaceuticals, contact drying must take place at low heating temperatures, at residence times in tune with the tolerance of the product, and...

Sparging refers to the process of injecting a gas through a diffuser into a liquid phase. It is used in both physical and chemical process applications. In physical process applications, the gas is used to either dissolve gas into liquid (such as aeration and carbonation) or to remove contaminants from the liquid phase (such as oxygen stripping, volatile organic compound stripping and water stripping). In...

Pumps are among the most commonly used machines in the chemical process industries (CPI). Condition monitoring tests and predictive maintenance can help pump operators determine when to overhaul pumps in a way that minimizes costs. Despite pumps’ ubiquity and large energy demands, however, relatively little information is available on how to apply predictive maintenance approaches and condition...

Corrections: From the October 2012 Letters page: This original article, which appeared in the print edition of Chemical Engineering (September 2012), had two errors: Equation (19) should read D = log (TH)-0.4, and Table 2 was missing decimal points in all numbers on both the x- and y-axes. The corrections are shown here. Recirculating cooling-water systems are essential parts of many facilities throughout...
