Feature
Kimre™ mist eliminators for sulfuric acid production Kimre has applied more than 40 years of successful experience building mist eliminators to provide the broadest available range of mist elimination options in sulfuric acid. Based on B-GON® media and enhanced by fiber bed filter technology, Kimre can tackle any sulfuric acid mist removal challenge. B-GON® Mist Eliminators are widely used in the gas cleaning and contact sections of sulfuric acid plants. Metallurgical, oleum producing, sulfur burning and regeneration plants rely on mist eliminators in drying towers, absorption towers, gas cleaning units and tail gas scrubbers to protect the quality of the product acid, protect downstream equipment from corrosion, protect the catalysts and ultimately protect the environment. Kimre offers a complete selection of mist elimination equipment for all sulfuric acid manufacturing applications including both knitted metal and structured B-GON® mesh for drying towers, traditional Brownian diffusion candle mist eliminators for absorption towers, and impaction candles using both traditional fiberglass and knitted mesh media, as well as Kimre B-GON® media. Kimre additionally offers innovative solutions for gas cleaning in metallurgical and regeneration plants as well as mist eliminators for tail gas scrubbers. Available in PFA-TEFLON® and ETFE polymers, as well as other plastics, the B-GON® products can handle any sulfuric acid operation up to temperatures of 400 degrees F. The unique structured design of BGON® mesh, shown in Fig. 1, enables cost competitive designs. For application by product and metallurgical plants, the performance is unmatched. Over the last few years, we have had the good fortune to replace mist eliminators from every other major supplier with resounding success.
Proven applications in sulfuric acid production include: Drying towers B-GON® Mist Eliminators provide extremely long life as replacements for knitted metal mesh. B-GON® candles can be supplied to provide high efficiency mist removal in a convenient cylindrical form. Kimre can also supply traditional metal knitted mesh and co-knit pads and candles. Absorption towers Kimre offers a full range of mist elimination options for absorption towers. High efficiency Brownian diffusion candles provide excellent separation of sub-micron mists. Dual wall concentric candles reduce pressure drop or increase throughput in limited space. Fiberglass, metal knitted mesh and B-GON® impaction candles provide high efficiency mist removal at an economical cost. Feed gas clean-up B-GON® Mist Eliminators are used for a variety of applications in raw gas clean-up operations particularly in combination with the SXF™ Semi Cross Flow technology. The AEROSEP® Multi-Stage Aerosol Separation technology is Kimre’s newest development for sub-micron aerosol removal. Tail gas scrubbing B-GON® Mist Eliminators are proven for optimum mist separation on tail gas scrubbers. Where extremely high efficiency is required, Kimre can provide high efficiency Brownian diffusion candles. Oleum vent scrubbing Kimre’s AEROSEP® Multi-Stage Aerosol Separation System has proven capable of easily removing the sub-micron sulfuric acid mist originating from oleum vapor’s
people on the move Roberts announces new executive vice president WINTERVILLE, N.C. – Roberts (formerly known as The Roberts Co.), with offices in Winterville and Raleigh, recently announced the addition of T. Jason Dunaway as Executive Vice President. Dunaway recently served as Vice President of Operations at CB&I, Power in Georgia and before that was Director and Business Manager for Shaw Group Inc., Power where he had previously served more than two years as a Prime Contract Manager in Charlotte, NC. Jason’s more than 18 yearsexperience in the industry, specifically in the area of internal and external customer relationship management, offers Roberts and their customers a broad and far-reaching T.

contact with atmospheric moisture. Kimre, Inc. manufactures the B-GON® Mist Eliminators out of thermoplastics ranging from polypropylene to PFA-Teflon®. This is advantageous over the stainless steel mesh with respect to corrosion resistance. B-GON® Mist Eliminators do not lose their shape from corrosion as stainless steel mesh can. In addition, the product has these advantages: —The unique structure is the most cleanable, reusable material available in the world. —Economics are particularly improved by reusing existing grids in almost all cases. —Available in large pieces, which enable very rapid installation and, where required, quick removal for cleaning and reliable reinstallation. —Able to handle more extreme conditions than other technologies due to wider ranges of fiber diameters. Kimre™ fiber bed mist eliminators can meet the most challenging mist elimination needs in oleum towers, high-temperature absorption towers and standard absorption towers. Using high efficiency fiberglass media, the Kimre™ fiber bed mist eliminators can achieve efficiencies greater than 99.9 percent on particles smaller than 1 micron
operations and commercial issues makes him the right fit for the position of Executive Vice President with Roberts,” stated Monty Glover, Roberts COO. “His focus on customer service is an excellent complement to the existing culture at Roberts, and we are very pleased to have Jason as part of our team.” For more information, visit www.robertscompany.com

and outlet loading below 15 milligrams per cubic meter. The B-GON® Mist Eliminators combine the best features of knitted mesh and plate-type mist eliminators. The ladder-like structure of the B-GON® mesh causes a change in direction of vapor flow that enhances droplet removal by impaction, interception and centrifugal actions. This structure also produces a cross flow of captured liquid that flushes particulates from the media. The improved drainage of the geometric structure is a big advantage over the knitted mesh pads. Finally, the interlocking structure provides the B-GON® Mist Eliminator with excellent resiliency and resistance to compression or “cold flow” of the media. The monofilaments in the B-GON® structure align approximately 93 percent of the fibers perpendicular to the gas flow for maximum droplet removal efficiency. The conventional knitted types seldom exceed 67 percent. The high number of fibers perpendicular to the gas flow allow for higher removal efficiency per unit of pressure drop, which corresponds to lower energy usage, lower operating costs and immediate results. The main advantages of the B-GON® material is the lower pressure drop per unit of collection efficiency, the improved liquid handling ability and resistance to plugging. When Kimre recommends a B-GON® Mist Eliminator or fiber bed filter to a customer, calculations are run on the various styles of material to optimize the price, performance, life and operating costs of the mist eliminator. The wide variety of styles allows Kimre, Inc. to provide customers with customized solutions for each individual process.
