In this issue ofProcess Heating, we have a lineup of articles intended to help you reduce your carbon footprint, optimize operations and streamline the equipment selection process.

Paul Wild, general manager of Toledo, Ohio-based Exothermics Inc., a subsidiary of Eclipse Inc., Rockford, Ill., kicks off the issue with “Reducing Your Carbon Footprint.” As Wild notes, if you think pollution control can be very expensive, you’re right. In the face of pressures to reduce emissions of gaseous pollution and a company’s carbon footprint, many companies are installing pollution control equipment. Fortunately, while not every company will be able to mitigate the cost associated with a pollution control system by implementing heat recovery, many can. Turn to this article to learn about how heat exchangers can be used to capture energy from exhaust streams.

Another way to reduce a company’s environmental footprint is to utilize alternate energy sources when possible. Robert St. Denis of Milwaukee-based Cleaver-Brooks describes how Olin Chlor Chemicals, a division of Olin Corp., Clayton, Mo., was able to do just that when adding a process boiler. Olin produces excess hydrogen gas as part of its production process. Cleaver-Brooks designed a system that allows Olin to fire its boiler with the excess hydrogen, when it was available, or with natural gas or No. 2 oil. The firing options ensure that the boiler has adequate fuel flow under all conditions.

Also in this issue, Guillermo Botti, a specialty fluids sales engineer with Solutia in Italy, describes how synthetic heat transfer fluids have been used to improve high temperature heat processing operations. Turn to this article to learn how Polimeri Europa, an Italian petrochemical company, switched to a synthetic heat transfer fluid for the plant’s ethyl benzene distillation column and gained improved thermal stability. In the second case history, Botti describes how Gutta Group, a manufacturer of building materials and garden products, was able to reduce fuel consumption and maintenance by choosing a synthetic heat transfer fluid.

In “Incredible Infrared,” Douglas Canfield, president of Casso-Solar Corp., Pomona, N.Y., and Bill Kolbeck, business unit manager, automation products, for Raytek Corp., Santa Cruz, Calif., team up to explain how infrared ovens and infrared temperature measurement devices work together to provide a powerful one-two punch in process heating applications. Infrared heaters will raise the product temperature much more rapidly than convection equipment due to infrared’s higher energy transfer rate. Precise temperature monitoring using noncontact infrared temperature sensing can help processors improve product quality and increase throughput. It also can help minimize downtime because production processes can proceed uninterrupted under optimal conditions.

Finally, in “It’s a Wrap,” learn how developments in equipment designs, materials and controls have made heat tracing an efficient means of avoiding heat loss and providing temperature control in process equipment.
