Beginners Guide to ChemCAD: Chemical Process Simulator

chemcad

Chemical process simulation is essential for the design, development, analysis, and optimisation of the processes. It is designed to help chemical engineers all over the world simulate real world systems.

This model-based representation of chemical process using different software helps increase the efficiency of an engineer. Before investing money, it is important to design and test different reaction systems.

 ChemCAD is one of the most widely used and respected processes simulation software and has application in fields as varied as education, refining, pharmaceuticals, etc.

As with any new software, there is going to be a learning curve. This guide hopefully makes the curve less steep and easier to navigate.

What is ChemCAD?

ChemCAD is an integrated suite of intuitive chemical process simulation software. It is designed to increase productivity, handle the toughest chemical process models, and help with daily tasks.

It has been used for equipment design, equipment sizing, process development, and dynamic simulations. Simulation with ChemCAD is based on a range of thermodynamic models and a large database of over 2000 components for gases, liquids, solids, and electrolytes.

Developed by Chemstations over 40 years ago, it has continuously evolved to meet the requirements of chemical engineers. Most processes in the chemical, petrochemical, pharmaceutical, mechanical, and environmental process technologies can be simulated using ChemCAD.

ChemCAD product suite

The ChemCAD software suite includes six products that can be bought individually or as a bundle.

CC-Steady State

It runs a steady-state simulation of continuous chemical processes. It has libraries of thermodynamic methods, chemical components, and unit operations that allow you to simulate processes from lab scale to full scale.

Suited for anybody who wants to rate or design processes in steady state.

CC-Dynamics

It can perform dynamic flowsheet analysis, PID loop tuning, operability check-out, operator training, and soft sensor functionality.

Suited for anybody who wants to rate or design dynamic processes.

CC-Therm

It can accurately perform the sizing of a heat exchanger. It can also design and rate shell-and-tube, plate-and-frame, air-cooled, and double-pipe exchangers.

Suited for anybody who wants to rate or design heat exchangers.

CC-Batch

It is a batch distillation simulation software that can design and preview scenarios with intuitive, operation step-based input. It is flexible, with many operating modes, can minimize intermediate ‘slop’ cuts, optimize batch production, and increase productivity.

Suitable for anybody who wants to design or rate a batch distillation column.

CC-Safety Net

With their piping and safety relief network simulation software, they can comprehensively analyze any pipe network.

Suitable for anybody who wants to design or rate piping networks or safety relief systems.

CC-Flash

It can calculate phase equilibria and physical properties with great accuracy for pure components and mixtures.

Suitable for anybody who wants the physical property and phase equilibrium data and those who want property prediction and regression.
