The foundation for designing or rating continuous chemical processes. It includes a database of over 2,500 components and 40+ thermodynamic methods.

Adds time-dependent analysis for batch reactors , control system design, and safety relief scenarios.

It features a redesigned optimization engine capable of finding global optimum conditions quickly through multiple starting positions run in parallel.

Precisely sizing vessels, pumps, valves, and column trays.

The calculation engine has been rewritten to utilize multiple CPU cores. This allows for significantly faster run times and improved convergence for complex simulations.

The "NXT" generation introduces several critical enhancements aimed at increasing engineering efficiency and computational speed:

Analyzing relief device performance and hazardous waste management.

Version 1.2.0 and later include NIST REFPROP as a built-in thermophysical property calculator, providing high-precision data for refrigerants and supercritical fluids.
