ChemCAD NXT isn't trying to be Aspen Plus. It is trying to be the for engineers who need to get work done without a six-figure annual budget. It respects your legacy files (imports .cc6 and .cc5 flawlessly) but shoves you into the modern era of simulation.
: Built-in access to the NIST REFPROP library for highly accurate thermophysical property calculations without requiring separate licensing.
The distillation module in ChemCAD NXT is world-class. It supports:
Chemcad NXT is a powerful chemical process simulation software that has revolutionized the way chemical engineers and researchers design, analyze, and optimize chemical processes. Its intuitive interface, advanced thermodynamic and kinetic models, and comprehensive mass and energy balances make it an ideal choice for a wide range of applications. By using Chemcad NXT, engineers can improve process efficiency, increase accuracy, and enhance productivity, ultimately driving innovation and growth in the chemical process industry.
The software supports , allowing engineers to balance competing goals such as maximizing steam production while minimizing total heat exchanger area. Results are visualized using Pareto front charts , which show the relationships between optima for specified objective functions.
Whether you are a chemical engineering student learning the fundamentals, a process engineer optimizing an existing plant, an EPC firm designing a new facility, or a researcher developing novel processes, CHEMCAD NXT provides the tools you need to succeed. The software helps engineers save time and money by enabling them to test ideas virtually before making costly real-world changes, supports innovation by reducing trial-and-error, and shortens the time from concept to commercial implementation.
For decades, process simulation has been the backbone of chemical engineering—from conceptual design to troubleshooting operating units. Many of us grew up with the classic ChemCAD interface: powerful, reliable, but undeniably showing its age. Enter .
As described in the Chemstations Knowledge Center , the "NXT" generation focuses on enhancing productivity and providing a more modern user experience compared to traditional simulation software. Key Features of Chemcad NXT
: Enables transition from initial design (steady-state) to time-dependent behavior (dynamics) for tasks like batch distillation, relief valve sizing, and control system analysis. Typical Engineering Workflow
A specialized tool for batch distillation that optimizes operation steps and minimizes intermediate "slop" cuts.
For chemical engineers navigating the complexities of process design, simulation, and optimization, having the right software is not just a convenience — it's a necessity. ChemCAD NXT, the flagship process simulation suite from , represents a significant leap forward in chemical process modeling technology. Since its launch in 2021, NXT has redefined how engineers approach everything from steady-state mass balances to multi-objective optimization, offering a modern interface, unprecedented speed, and a host of advanced features that streamline workflows and drive innovation.
ChemCAD NXT includes a accessible from the Analysis tab. Engineers can define objective functions using four methods: single stream/unit operation variables, equations (multiple variables), code in the ChemCAD editor, or code in an external user file.
ChemCAD NXT is widely deployed across a diverse range of industries:
