Refining
Refinery Digital Twin
One twin of the crude unit links column hydraulics, exchanger duty, steam and fuel gas — the four classic loss drivers watched together, not in four spreadsheets.
Industries, use cases & business value
Built for every process industry
Wherever there is a control system and a historian, EPSILON turns the data already being produced into a living model of the plant.
Oil & GasUpstream, midstream, downstream
Chemicals & PetrochemicalsComplex, highly recycled plants
Power & UtilitiesGeneration, steam and energy
Water & WastewaterTreatment, distribution, compliance
PharmaceuticalsBatch tracking and traceability
Food & BeverageQuality, yield and consistency
Digital twins in practice
Four twins, one platform
Utilities
Steam & Energy Optimisation
Boiler and turbine performance linked directly to energy KPIs and emissions — steam-loss and optimisation opportunities surfaced in real time.
Chemicals & polymers
LDPE Reactor Digital Twin
Reactor zone temperatures tracked live against the grade recipe; SimTwinTM predicts MFI and density ahead of the lab, so transitions are shorter and off-spec is caught early.
Melt flow index2.14 g/10min
Density0.923 g/cm³
Grade match98.7%
Green hydrogen
Hydrogen Value Chain Simulation
The full green hydrogen chain — renewable-powered electrolysis through compression, storage and liquefaction — with continuous energy-balance tracking.
Business value
Measurable impact across the plant lifecycle
Fewer engineering hours
One platform across the lifecycle — no duplicate tools or rework.
Fewer unplanned shutdowns
Early warnings and predictive maintenance cut downtime risk.
Lower energy & emissions
Optimised operations reduce utility cost and carbon footprint.
Faster root cause
Answers in minutes, not days, with pattern-based search.
One source of truth
A single contextualised backbone connects every discipline.
