DWSIM

DWSIM · Process Simulation

02040608010062EPC INDEX

The best free process simulator available and a genuine asset for teaching and early studies. Not a replacement for commercial suites on contract deliverables.

FIG. 003

Aspen HYSYS

AspenTech · Process Simulation

02040608010084EPC INDEX

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.
