Tail Gas Scrubbing Project

Back to case studies

The plant is located within the Pasminco smelter zinc refinery in Hobart, Tasmania. The project involved the design and construction of a zinc refinery off-gas cleaning system for scrubbing sulphur dioxide from furnace off-gases.

The installation included a salt water intake straining station, contact scrubbing towers, reticulation piping and ductwork.

Ausenco’s scope included:

  • preparation of a definitive capital cost estimate to obtain board approval
  • feasibility study, process development and detailed engineering and preparation of all specifications
  • procurement, inspection and expediting for all equipment
  • preparation and administration of all fabrication and site works contracts
  • site construction management and commissioning assistance of the plant
  • project management and associated cost control, reporting and scheduling.

Due to the potential for corrosive attack, fibreglass materials were used extensively during construction.
