Pasadena, Calif. — Jacobs Engineering Group Inc. reports that its Chemetics® unit in Pickering, Ont., was awarded a design and fabrication contract by Aurubis Bulgaria AD for two proprietary designed sulfuric acid coolers to be installed in its acid plant in Pirdop, Bulgaria. The scope of work involves the design and fabrication of drying and interpass anodically protected sulfuric acid coolers. The interpass cooler is being custom designed to operate in current operating mode, as well as allowing for use in a future heat recovery project. Jacobs worked with Aurubis engineering staff to develop a solution that would allow optimal performance in both distinctly different operating modes. These technical discussions also led to improvements in the process design for the water flow to the existing acid coolers. Chemetics has had a long work relationship with the Pirdop facility since 1998. Past projects include acid coolers and the most recent project in 2007 for four Electrolyte Heaters. The Pirdrop facility produces anodes, cathodes, and sulfuric acid.
