Jacobs Engineering Group announced Tuesday its Canada-based
Chemetics unit in Pickering, Ontario, was awarded a design and
fabrication contract by Aurubis Bulgaria for two proprietary
designed sulfuric acid coolers to be installed at its acid
plant in Pirdop, Bulgaria.
The scope of work involves the design and fabrication of
drying and interpass anodically protected sulfuric acid
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, the company said.
These technical discussions also led to improvements in the
process design for the water flow to the existing acid
Jacobs' Chemetics unit has had a long and mutually
successful work relationship with the Pirdop facility since
1998, the company said. Past projects include acid coolers and
the most recent project in 2007 for four electrolyte
