AVEVA PRO/II Simulation

AVEVA · Process Simulation

A proven steady-state workhorse for refining, now positioned as the predecessor to AVEVA Process Simulation. Good for existing models; plan the long-term path.

FIG. 003

Aspen HYSYS

AspenTech · Process Simulation

The benchmark simulator for oil and gas and refining. Its depth and the size of its user community make it the safe default for EPC process teams in hydrocarbons.
