Relevant Project Experience

  • PROJECT | Baghouse Incident Investigation Muja Power Station
    Investigation into a baghouse dust explosion / fire incident at Muja power station in 2014.
    Activities included site visit, involvement in client's internal incident investigation, process evaluation to establish cause of incident and recommendations to prevent reoccurrence.
    Similar investigations, including risk assessments have been completed for coal, grain, minerals, pharmaceuticals and toner powder processing facilities.
  • PROJECT | Natural Gas Replacement using Waste Biomass Tasmanian Alkaloids
    Technical and management activities in detailed feasibility study to evaluate the technical and economic viability of replacing the existing natural gas boilers with technology utilising waste biomass.
    The scope of work included biomass characterization, investigation of energy load requirements, technology evaluation, process modelling, liaising with project stakeholders (eg.client, council, utility companies), and economic evaluation.
  • PROJECT | Upgrading of Coal and Other Fuels to Value Added Products
    Significant contribution to FEED study for conversion of coal to value-added products via gasification. Included design of dryers, conveyors, pressure vessels, filters and separators.
    Managed extensive research project to evaluate options for conversion of Victorian brown coal to value-added products via gasification.
    Managed an extensive program to evaluate the techno- economic feasibility of activated carbon production from brown coal. Included pilot-scale and commercial-scale trials.
  • PROJECT | Bench and Pilot-Scale Research and Development
    Development / operation of bench and pilot-scale rigs to simulate processes including drying, dewatering, pyrolysis, and gasification (fixed bed, underground, fluidized bed).
    Involvement in recommissioning and operation of HRL's 200kg/hr gasification pilot plant.
  • PROJECT | Review of Alternatives to Waste to Landfill East Gippsland Shire Council
    Managed desktop feasibility study to identify and evaluate options to resolve the shire's issues with regard to waste management.
    Included technical review of available technologies, identification of prospective options and economic modeling of options.
