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. Jacobs’ Chemetics unit has had a long and mutually successful work relationship with the Pirdop facility since 1998. Past projects include acid coolers and the most recent project in 2007 for four Electrolyte Heaters. Aurubis is a leading integrated copper group and the world’s largest copper recycler. It has 16 production sites in 11 European countries and the U.S., as well as an extensive service…
