Building on our past. Ready for the future

Worley is a global professional services company of energy, chemicals, and resources experts headquartered in Australia. Right now, we’re bridging two worlds as we accelerate to more sustainable energy sources, while helping our customers provide the energy, chemicals, and resources that society needs now.

We partner with our customers to deliver projects and create value over the life of their portfolio of assets. We solve complex problems by finding integrated data-centric solutions from the first stages of consulting and engineering to installation and commissioning, to the last stages of decommissioning and remediation. Join us and help drive innovation and sustainability in our projects.

Chemical Process Modelling Specialist

About Worley:

Worley has made a firm commitment to support the energy transition, and we are rapidly expanding our capabilities within the low carbon and Energy Transition sectors. Central to this is ensuring project delivery adheres to cost, schedule, and quality and meets appropriate legislation and standards.

Our project delivery team brings experience and track record from a range of industry sectors to ensure similar standards are maintained as we assist our clients, partners, and projects in transitioning to a more sustainable world.

Our commitment to People, Planet, and Sustainability is demonstrated in Worley’s broader ambitions in the energy transition space and extends from early-stage concept and feasibility through to delivering full EPC and EPCM packages.

Role Context:

The Mining, Minerals, Metals, and Battery Materials business is looking to employ experienced Subject Matter Experts (SME), together with Principal and Senior Minerals Processing and Battery Materials Process Engineers within depth capability of Mineral processing, Hydrometallurgy, and Pyrometallurgy. To support our activity in this area we have a growing requirement for individuals with Specialist skills in Process Modelling.

They will be proficient in modelling and simulation with capability to interface across the process value chain from Mineral processing to hydro- and Pyro-metallurgy. Be able to work and travel to our offices and Client sites to provide expertise, guidance, and Minerals Processing and Battery Materials Processing design services.

You will provide process engineering services on large or mega projects to Worley and its customers, including technical support and supervision within the process engineering team.

Be experienced in undertaking engineering studies to the level of detail as guided by the study phase required by the client (scoping study, pre-feasibility, definitive or bankable feasibility, or a detailed design). Use mine schedule information to refine designs.

Generate documentation to cover items such as circuit design philosophy, process design criteria, circuit description, process flow diagrams with mass balance, P&IDs, major equipment calculations and specifications, control philosophy, and functional design specification. Be able to liaise with equipment vendors in relation to equipment selection and design.

Coordinating with external engineering consultants on process design as required.

Chemical Process Modelling Specialist Role Description:

• Chemical process modelling is a computer modelling technique used in chemical engineering process design.
• It typically involves using purpose-built software to define a system of interconnected components, which are then solved so that the steady-state or dynamic behaviour of the system can be predicted.
• The system components and connections are represented as a process flow diagram or a set of interconnected Process Flow Diagrams.
• Simulations can be as simple as the mixing of two substances in a tank or as complex as an entire alumina refinery. This is commonly termed “Digital Twin”.
• Chemical process modelling requires knowledge of the properties of the chemicals involved in the simulation, as well as the physical properties and characteristics of the components of the system, such as tanks, pumps, pipes, pressure vessels, and so on.
• Analysis of existing process problems and define robust and innovative solutions with limited oversight.
• Reporting simulation outcomes and sensitivity analysis used to reconcile and optimise plant operations.
• Collaborate with other discipline engineers/scientists to optimise and improve existing processes leveraging advanced process modelling techniques.
• Improvements and calibration of the simulation to better predict outcomes using published and verified test-work data.
• Collaborate closely with the advanced process controls/automation teams in the implementation of controls strategies which leverage first principles models for real-time process automation.
• Ownership role over the linear programming model and economic evaluation, maintaining data quality and driving the model.
• Actively contributing to the innovation and ideation process through the use of modelling tools. Continual development of professional skillset.

You’ll be:

Experienced and knowledgeable in the following areas:

• Hydrometallurgical unit operations including but not limited to:

o Leaching (Heap, Tank/Vat Atmospheric etc.)
