Queensland Fertilizer Project - Gypsum Handling & Stacking System

Back to case studies

Innovative dry handling and wet ‘stacking’ technique used

Detailed design and part procurement of materials handling system and HDPE lined storage ponds for containment of gypsum by-product in ‘stacks’. The system comprised conveyors, stacker and reslurrying systems, drainage systems, stormwater diversions, decant and water re-use systems.

Ausenco’s scope included the options innovation and analysis; preparation of flowsheets, P&ID’s and control philosophy; management of and interaction with the Gypsum stack detailed design; interaction with the relevant government authorities including preparation/compilation of technical component of WMCF submissions relating to gypsum stacking and handling; detailed engineering design and preparation of technical specifications; technical evaluations for procurement by the client and partial procurement of equipment; compilation of construction scope of work and construction assistance; and engineering and operational support to WMCF for the first 16 months of system operation.

  • First use of innovative dry handling and wet ‘stacking’ technique in Australia
  • Provision of operational management during commissioning and the first 3 months of production ramp-up
  • Process design to facilitate conversion gypsum from hemihydrate to dihydrate form
  • Creek system diversion to cater for major rainfall events
