Process Modeling Engineer
Leads development and validation of steady-state and dynamic process models for integrated mineral refining systems. Requires 8+ years of process simulation experience, engineering expertise in transport and thermodynamics, and proficiency with industrial simulation tools.
About the job
Responsibilities
- Develop steady-state and dynamic process models for integrated mineral refinery systems, including heat and material balances, using ASPEN Plus/HYSYS, SysCAD, OLI Studio, or METSIM.
- Automate equipment and process sizing for reactors, heat exchangers, filters, crystallizers, evaporators, and separators, linking models to datasheets and engineering tools.
- Develop and maintain process simulation databases with consistent, traceable modeling assumptions, test data, and engineering deliverables.
- Calibrate and reconcile models using pilot or plant operating data to improve fidelity and predictive accuracy.
- Conduct process optimization studies covering energy and heat recovery, recycle strategies, and material efficiency.
- Develop dynamic models to validate PLC and DCS programming and optimize buffer sizing.
- Link process models to CAPEX and OPEX estimation tools and automate technoeconomic model development.
- Document modeling methodologies and results for design reviews, techno-economic assessments, and regulatory submissions.
- Provide technical leadership, establish modeling standards and best practices, mentor junior engineers, and collaborate with R&D, pilot operations, and project execution teams.
Requirements
- Bachelor's degree or higher in Chemical Engineering, Mechanical Engineering, Process Engineering, Metallurgical Engineering, or a closely related discipline.
- 8+ years of experience developing and applying process simulation models for chemical processing, hydrometallurgy, mining, refining, or related industrial process systems.
- Proficiency with one or more of ASPEN Plus/HYSYS, SysCAD, OLI Studio/OLI Flowsheet, or METSIM.
- Strong understanding of mass transfer, heat transfer, thermodynamics, fluid flow, and reaction engineering.
- Experience developing material and energy balances for multi-step, integrated process systems.
- Strong understanding of chemical equilibria and phase behavior in aqueous and non-aqueous systems.
- Familiarity with data reconciliation, parameter fitting, and model validation using experimental or operational data.
- Experience integrating process modeling outputs into EPC deliverables such as PFDs, P&IDs, equipment datasheets, and control narratives.
Nice-to-haves
- Python or MATLAB experience for model automation, data processing, and custom calculations.
