Scalable CHEMCAD Suite

The CHEMCAD suite includes six products that can be purchased individually or bundled as needed to accommodate specific industries, projects, and processes.

The CHEMCAD Suite of Products Includes:

Run steady-state simulations of continuous chemical processes with CC-STEADY STATE. This product features libraries of chemical components, thermodynamic methods, and unit operations, enabling you to simulate processes from lab scale to full scale.

Ideal for: Users who want to design processes, or rate existing processes, in steady state.

Take steady-state simulations to the next level of fidelity and conduct dynamic flowsheet analysis with CC-DYNAMICS. The possibilities are endless: operability check-out, PID loop tuning, operator training, even online process control and soft sensor functionality.

Ideal for: Users who want to design or rate dynamic processes.

CC-THERM makes use of multiple international standards for design and materials so you can streamline the process of sizing a heat exchanger accurately. Available as an add-on or standalone product, the design and rating program covers shell-and-tube, plate-and-frame, air-cooled, and double-pipe exchangers. Rigorous designs are based on physical property and phase equilibria data.

Ideal for: Users who want to design or vet a design by a heat exchanger vendor (single unit at a time), and those who want to rate existing exchangers in new service or perform "what if" calculations.

Batch distillation simulation software allows you to efficiently design and preview scenarios with intuitive, operation step-based input. CC-BATCH is extremely flexible, with many operating modes and the capability to model any number of operating steps and conditions. Optimize batch operation, minimize intermediate "slop" cuts, and increase productivity.

Ideal for: Users who want to design or rate a batch distillation column.

Thoroughly analyze any pipe network with our piping and safety relief network simulation software. CC-SAFETY NET combines the latest in two-phase relief device calculation, pressure drop calculation, physical property calculation, and precise phase equilibrium calculation to deliver fast, accurate answers.

Ideal for: Users who need to design or rate piping networks or safety relief devices/systems.

Use CC-FLASH to calculate physical properties and phase equilibria (VLE, LLE, VLLE) for pure components and mixtures with incredible accuracy. All products within the CHEMCAD suite feature CC-FLASH capabilities.

Ideal for: Users who need physical property and phase equilibrium data, as well as users who need property prediction and regression.
