    Process Modelling and Simulation

    Whether you’re launching a new distillery or expanding capacity, our expertise ensures efficient, scalable and environmentally responsible production.

    Process Modelling that Makes a Difference

    Process modelling and simulation give operators, designers and investors the clarity needed to make confident technical decisions. By analysing how processes behave under real operating conditions — steady‑state, dynamic, transient and emergency — modelling provides the evidence base for safe, efficient and commercially sound design. It underpins FEED, optimisation, debottlenecking and long‑term asset planning, ensuring that engineering choices are grounded in data, not assumptions.

    At Arthian, we combine advanced modelling tools with deep process engineering expertise to help clients understand performance, identify constraints and reduce risk across complex industrial facilities. From energy integration and throughput analysis to safety‑critical scenarios and COMAH‑driven studies, our modelling work strengthens design, improves operability and supports regulatory‑ready decision‑making across chemical, manufacturing, utilities and high‑hazard sectors.

    Our Process Modelling & Simulation Services

    Steady‑State Modelling
    Used to evaluate process performance under normal operating conditions.

    • Mass and energy balances
    • Equipment sizing and specification
    • Process flow optimisation
    • Heat and energy integration
    • Utility demand modelling


    This forms the basis for FEED & Concept Design and early‑stage investment decisions.

    Dynamic Simulation
    Dynamic models help operators understand how processes behave during:

    • start‑up and shutdown
    • transient conditions
    • upset scenarios
    • emergency events
    • control system changes


    Dynamic simulation is essential for high‑hazard and COMAH facilities where process behaviour must be fully understood.

    Bottleneck & Throughput Analysis
    We identify constraints that limit production capacity and develop targeted improvements.

    • Flow restrictions
    • Heat transfer limitations
    • Pumping and transfer constraints
    • Control system interactions
    • Equipment performance issues


    This work often feeds into Process Optimisation and debottlenecking programmes.

    Scenario Modelling & Sensitivity Analysis
    We test “what‑if” scenarios to support design, safety and operational decisions.

    • Feedstock variation
    • Temperature and pressure changes
    • Equipment failure scenarios
    • Control strategy adjustments
    • Energy price and demand fluctuations


    This supports risk reduction, cost optimisation and long‑term planning.

    Energy & Heat Integration Modelling
    Modelling is a powerful tool for identifying energy‑saving opportunities.

    • Heat recovery potential
    • Thermal integration
    • Utility optimisation
    • Carbon reduction pathways


    This integrates directly with Industrial Decarbonisation and net‑zero strategies.

    Safety‑Critical Modelling
    We support safety studies with modelling that informs:

    • relief system sizing
    • overpressure scenarios
    • venting behaviour
    • runaway reactions
    • emergency shutdown sequences

    Where Process Modelling Adds Value

    We support clients across:

    • chemical manufacturing
    • industrial manufacturing
    • pharmaceuticals
    • food & beverage
    • energy & utilities
    • COMAH and high‑hazard facilities
    • bulk fuel storage and terminals
