LNG
Predict Performance. Optimize Operations. Ensure Safety.
Simulate systems to pinpoint bottlenecks, manage boil-off and surge, and validate capital projects.

Design LNG processes
Drag-and-drop unit operations, explore phase behavior, and reconcile heat- and material-balance results with plant data. Quantify boil-off, compressor duty, and vapor–liquid splits early in design to confirm capacities and utilities before committing budget.
Simulate transient events
Dynamic simulation captures changes in pressure during system ramp-up, emergency shutdown, or flare release. Built-in PID controllers let you test tuning and validate trip setpoints to maintain cryogenic margins and prevent two-phase flow.
Size and rate equipment
Integrated design and rating tools calculate exchanger UA, approach temperature, and pressure drop; estimate compressor polytropic head and power; and determine tray or packing requirements for fractionation. Export vendor-ready datasheets to shorten bidding cycles and align mechanical designs with process needs.
Evaluate steady-state pressures
Evaluate pump head, line diameter, valve Cv, and NPSH for LNG transfer lines, loading arms, and vapor return headers. Identify choking or excess velocity early, then iterate line-ups to balance cost and pressure drops.

Analyze surge and water hammer
Model valve closures, pump trips, and liquid columns to predict pressure waves and pipe wall stresses. Evaluate mitigation plans for surge vessels, slow-close valves, or staged sequencing to keep pressures within allowable limits.
Analyze Surge Events
Analyze compressible gas flow and relief networks.
Predict pressure, Mach number, and choke points in boil-off, flare, and vapor-return lines; size relief valves, regulators, and piping to meet API requirements.
