Project Objectives:

Assist in the management of fugitive emissons from their Port Karumba Product Storage Shed Facility.  The facility is used for the stockpiling of lead and zinc sulphide prior to export.

Our Role:

• Developed a CFD (Computational Fluid Dynamics) model to predict airflow patterns within and around the Shed.  The model incorporated natural (wind-induced) ventilation as well as the interaction with the internal mechanical ventilation and extraction system.
• Developed a methodology to quantify particle egress from the zinc sulphide and lead sulphide stockpiles so that Shed Ventilation System modifications could be properly evaluated. 
• Validated CFD results against measurement  data. 
• Developed a series of Ventilation System improvements aimed at minimising particle egress from the Shed, in particular SO2 emissions.  These options were primarily directed at eliminating "dead zones" known to trap the SO2 emissions and increase equilibrium concentrations.
