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 dehydrate form
- Creek system diversion to cater for major rainfall events
