In-depth analysis not rule-of-thumb shortcuts
As a process plant design company, jimmylea delivers professional services in plant engineering design, chemical engineering expertise, commercial plant scaleup and emerging energy projects.
Our methodology stands apart through rigorous, data-driven analysis rather than reliance on generic industry guidelines. This approach ensures every solution is tailored to the specific technical, operational and commercial requirements of the project.
Avoid overdesign. Slash fabrication and project costs.
Rule-of-thumb methods can result in overdesign, increasing fabrication costs, equipment sizes and project expenditure, or underdesign, leading to poor performance and operational risk. We minimise these risks through disciplined engineering, advanced simulation and detailed technical evaluation, delivering solutions that are both technically robust and commercially effective.
Our work focuses on the chemical, energy, resources and water industries, where complex fluids, demanding process conditions and strict regulatory requirements demand far more than standardised approaches. These environments require sound technical judgement, deep industry knowledge and practical project experience.
Practical, buildable, reliable results
Real value is achieved when engineering excellence is combined with industry-specific insight and a commitment to solutions that can be constructed, commissioned and operated successfully.
Our team is supported by advanced in-house simulation capabilities, including ASPEN Plus, HYSYS, ANSYS Fluent and other specialist software. These tools allow us to evaluate, validate and optimise solutions with a high degree of confidence before fabrication or construction begins.
This integrated approach delivers outcomes that are technically sound, economically effective and aligned with project objectives. When you engage jimmylea, you gain a trusted engineering partner delivering practical, buildable solutions across Australia and Singapore.
Our engineering activities are led by Dr Jimmy Lea PhD FIEAust CPEng RPEQ, a Fellow and Chartered Professional Engineer with Engineers Australia.
Plant Engineering Design
Our plant engineering design services are centred on delivering robust, fit-for-purpose industrial facilities that perform safely and reliably. We bring together process, mechanical, instrumentation and layout engineering to define clear design intent, establish sound operating conditions and transform process requirements into practical engineered systems. Our plant engineering services include:
- Multidisciplinary detailed engineering design for construction
- Design of plants that process materials in solid, liquid and/or gas phases
- Integrated control and safety systems (ICSS) incorporating BPCS, alarms and safety interlocks
- Safety instrumented systems (SIS) including LOPA for SIF definition and SIL verification
- Compliance with regulatory requirements, standards and design codes
- Distributed control system (DCS) or modular programmable logic controller (PLC) system design
- Mechanical engineering design including GD&T, 2D drafting and 3D geometrical modelling
- Plant layout, pipe routing and general arrangement (GA) design
- Procurement, inspection and receipt of equipment on behalf of clients
- Factory acceptance testing (FAT) and witnessing

Chemical Engineering Expertise
Our chemical engineering expertise services apply the fundamental core principles of chemical engineering to understand, design and optimise industrial processes. We integrate chemical reaction engineering, thermodynamics, transport phenomena and process modelling to predict how materials and energy behave within process systems and translate this understanding into safe, efficient and practical process designs.
- Chemical reaction engineering, reaction kinetics and reactor performance analysis
- Mass transfer and coupled heat, mass and momentum transport analysis
- Thermodynamic, phase-equilibrium and physical-property analysis
- Non-Newtonian and complex-fluid process engineering
- Multiphase flow, particle behaviour, sedimentation, suspension and fluidisation analysis
- Design and analysis of separation processes and chemical engineering unit operations
- Process modelling, mass and energy balances and process simulation
- Hydraulic and thermal analysis of process systems
- Residence time distribution, mixing and reactor hydrodynamic analysis
- Process integration, pinch analysis and heat recovery optimisation
- Heat exchanger thermal design and performance assessment
- Process optimisation, scale-up and operating-envelope development

Commercial Plant Scaleup
Clear commercial plant scaleup is essential for transitioning reliable industrial plants from pilot to full production, particularly for first-of-a-kind systems where scaling uncertainties are highest. It refines the process route, adapts the design basis for industrial realities, and shapes the technical direction for seamless commercialisation. At Jimmylea, we use first principles and modelling insight to mitigate scale-dependent risks early and form scalable solutions that are practical, safe, and ready to advance into full plant engineering.
- Defining scalable process configurations and preparing detailed mass and energy balances
- Identifying key scaleup parameters and establishing operating ranges industrial capacity
- Sizing and selecting unit operations and critical equipment for full-scale operation
- Preparing geometric, dimensioning and tolerancing drawings for equipment definition in scaleup
- Developing control strategies to support stable and safe plant operation
- Using advanced simulation tools to assess flow behaviour, heat exchange and reaction performance
- Ensuring early designs integrate effectively with control, safety and operability requirements
- Preparing commissioning and operational plans that align with the defined process route

Emerging Energy Engineering
Our emerging energy engineering services help clients progress novel clean energy technologies from concept into engineered processes. We apply process engineering fundamentals, simulation driven design verification and detailed plant engineering to translate new technologies toward commercial scale. Our structured workflow removes guesswork, reduces uncertainty, clarifies operating envelopes and ensures that new technologies can be integrated safely and reliably into real facilities. Our emerging energy engineering services include:
- Conceptual and chemical process engineering design
- Front-end-engineering design (FEED) and multidisciplinary detailed engineering
- Design of integrated control and safety systems (ICSS) incorporating BPCS, alarms and SIS
- Developing process flow diagrams (PFDs) and piping & instrumentation diagrams (P&IDs)
- Engineering of unconventional energy systems to meet regulatory and approval requirements
- Design of distributed control systems (DCS) and programmable logic controller (PLC) systems
- Mechanical engineering design supported by 2D drafting and 3D geometrical modelling
- Design and sizing of utility systems, reactors, adsorption columns and gas separation equipment
- Performance evaluation of all major unit operations
- Evaluation of plant safety using prescriptive methods and simulation-based analysis
- Design verification of process unit operations using advanced in-house simulation
