Industrial Process Engineering & Process Design Consultants
Process Engineering Expertise to Drive Performance, Safety and Sustainability
Engineering safer, more efficient and future‑ready industrial processes
Industrial organisations rely on processes that must be safe, efficient, compliant, and resilient. Arthian’s process engineering consultants help clients design, optimise, and transform complex industrial systems — improving performance, reducing risk, and enabling sustainable growth across highly regulated sectors.
Our multidisciplinary team brings decades of experience in chemical engineering, process design, FEED, optimisation, modelling, and process safety, supporting projects from concept through to commissioning and operational improvement.
Industrial Process Design Consultants
Industrial process design is not simply about equipment selection or flow diagrams — it is about engineering systems that work reliably in real‑world conditions. Our clients choose us because we deliver:
- Technically robust, regulation‑aligned designs for COMAH‑tier, high‑hazard and highly regulated environments
- Optimised processes that reduce energy, water, waste, and operating costs
- Safe, compliant operations through integrated process safety and risk reduction
- Future‑ready systems designed for scalability, automation, and decarbonisation
- End‑to‑end lifecycle support from feasibility to commissioning and continuous improvement
Our Industrial Process Engineering Services
Process Design & Development
We design new processes and upgrade existing systems to improve performance, safety, and compliance. Our work includes:
- Concept design and feasibility studies
- Process Flow Diagrams (PFDs) and P&IDs
- Mass and energy balances
- Equipment sizing and specification
- Integration with utilities, controls, and safety systems
This forms the foundation of a scalable, efficient, and compliant process.
Process Modelling & Simulation
We use advanced modelling tools to predict system behaviour, optimise performance, and de‑risk investment decisions.
- Steady‑state and dynamic simulation
- Scenario modelling and sensitivity analysis
- Throughput and bottleneck analysis
- Energy and heat integration modelling
FEED (Front‑End Engineering Design)
Our FEED packages provide the clarity needed for accurate costing, procurement, and project planning.
- Basis of Design (BoD)
- Process descriptions and design criteria
- Equipment lists and datasheets
- Control philosophy
- CAPEX/OPEX evaluation
Process Optimisation & Efficiency Improvement
We help clients unlock measurable improvements in productivity and sustainability.
- Debottlenecking and throughput improvement
- Energy efficiency and heat recovery
- Water and waste reduction
- Process control optimisation
- Operational diagnostics and root‑cause analysis
Process Safety & Compliance
Safety is engineered into every stage of our process design work.
- HAZID, HAZOP, LOPA and SIL assessments
- COMAH support and regulatory compliance
- Relief system design and verification
- Functional safety and SIS lifecycle support
- Process hazard analysis (PHA)
Commissioning, Operations & Lifecycle Support
We support clients beyond design — ensuring systems operate safely and efficiently.
- Commissioning planning and support
- Operational readiness assessments
- Operator training and documentation
- Troubleshooting and performance improvement
- Data analytics for process monitoring
Specialist Process Engineering for Bulk Fuel Storage & Tank Farms
