Pickle Line Complex

Complex included a Pickle Line Building, an Acid Regeneration Plant and a new Pumphouse. The 95,000 sq. ft. Pickle Line Building was constructed for continuous strip acid cleaning of steel coils with associated truck unloading building and pollution control systems. The new Acid Regeneration Plant encompassed a new four-level structure complete with overhead crane, gravity ventilation, and specialized floors with acid-resistant brick and rubber lining to resist the acid fumes generated by the process. The new pumphouse was located remote from the Acid Regeneration Plant in order to allow for the future expansion of the plant and the installation of a new concrete tank farm for the storage of fresh and recycled acids.

Atkinson Engineering was responsible for the design of the subsurface preparation in the Queenstown shale for the building and equipment foundations including investigation of materials to protect against rock squeeze resulting from the deep rock blasting cuts. Complete building package was prepared including building and equipment foundations, mill buildings and structures, roof gravity ventilation and access platforms to roof mounted condensers. Project also included design of compressor buildings, offices with computer control rooms, electrical switchgear rooms, soundproof acid exhaust fan intakes, outlets and enclosure, acid resistant tank farm with foundations and acid tank service levels, specialized support structures for FRP acid exhaust stack and sampling port access platforms and acid truck overhead unloading station.
