Carbone Lorraine (CL; Paris, France; edlinks.che.com/7372-538) is launching a new welded-plate heat exchanger, dubbed Heatex, which features plates made of tantalum CL-Clad. The patented CL-Clad technology involves the brazing of steel onto "reactive" metals, such as tantalum, titanium and zirconium, in order to fabricate columns, reactors and (now) heat exchangers used in corrosive service. Such...

The batch reactor is the workhorse of the fine chemical and pharmaceutical industries. Within it, many different unit operations are performed such as chemical reactions, bioreactions, crystallization, distillation and dissolution. Despite their significance to the industry, batch reactors have been controlled by the same underlying method for the past 50 years. This article discusses a relatively...

Tube plugging is probably the most frequently used maintenance and repair technique for the tube side of an exchanger. This article provides information on how to locate the positions of tube failures and discusses why it is important to know such information. It describes how to find out where the tubes failed and explains how to analyze what caused failures, seen from the tube side. Descriptions of...

Hydrocarbon leaks can disrupt recirculated cooling-water systems. Here’s an outline of effects and remedies Water is often the fluid of choice for cooling systems in the chemical process industries (CPI). Recirculated cooling-water systems are used to control the temperature of process fluids, which is necessary for process control and to achieve target product yields and specifications. Hydrocarbon...

As the price of electricity, natural gas and other fossil fuels continues to climb, chemical processors are more closely examining high-temperature operations and heat-transfer systems to see if more efficiency can be had. In many cases it can, and, as a result, heat-transfer projects are not only justifiable, but downright attractive. "Traditionally we used to see chemical processors looking at their...

Researchers from the fluid-dynamics laboratories at CSIRO Manufacturing and Materials Technology (Melbourne, Australia; edlinks.che.com/6898-534) have developed a new heat-exchange technology, called RAMeX, which performs heat exchange and mixing of highly viscous fluids without stirrers, impellers, baffles and plates. Like the Rotated Arc Mixer (RAM; CE, February 2001, p. 17) from which it evolved, the...

    The use of shell-and-tube heat exchangers is widespread in the chemical process industries (CPI). In applications where contact between shell- and tube-side fluids is not tolerable, it is important for the engineer to understand some of the design details that ensure leak tightness. In his work, the author has found a great deal of literature that addresses the strength and tightness of tube...

    Heat transfer takes place in every plant in the chemical process industries (CPI), and in a significant proportion of individual equipment items. And of the many varieties of heat exchanger, shell-and-tube versions must surely be the most traditional. Doyle & Roth Mfg. Co. Inc. (New York) has been serving the process industries since 1932, and supplies a full range of shell-and-tube...
