Engineering Simulation Tools

Datacor’s simulation software validates LNG upgrades, evaluates surge, and helps engineers design safe and efficient systems.

CHEMCAD

Modern chemical process simulation software designed with the engineer's workflow in mind to help efficiently identify innovative solutions.

Fathom

Calculate steady-state hydraulic pressure drop and pipe flow distribution in liquid and low-velocity gas piping and ducting systems.

Arrow

Determine the pressure drop and flow distribution, analyze sonic choking, and model real gases in steady-state gas and steam piping systems.

Impulse

Analyze pumping systems for harmful pressure surge transients caused by water hammer.

xStream

Analyze high-speed, acoustic transients that occur in steam and gas piping systems.

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 Your Process
LNG-1 LNG-1

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.

LNG-2 LNG-2

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.
Review Equipment Sizing
LNG-3 LNG-3

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.

LNG-4 LNG-4

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
LNG-5 LNG-5

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.
