CHEMCAD is designed to work for engineers and with engineers. Our proprietary solutions will allow your firm to work faster with more accurate results.




COSTELLO specializes in the sales and training in the use of ChemCad software. In addition, we are experts in building custom process models for our clients



COSTELLO provides ChemCad software as the authorized factory representative for the United States and Canada. In addition we provide training and custom simulation design for clients throughout the world.



COSTELLO provides custom training where your process model is built during the training session. We provide this service worldwide. These can be all types of simulations including biofuels, chemicals, specialty chemicals, pharmaceuticals, natural gas, incineration, and refining. Size of class can be 2 to 10 students at your location. Call for information.

Carbon Capture Power Plant

We currently use a process simulation software package to perform the following functions:

  • Design of new processes

  • Troubleshooting of existing processes

  • What if studies

  • Sizing of heat exchangers, columns and absorbers, and control valves etc.

  • Providing clients with a model of their existing process for their own in house studies.

  • Optimization of processes for increased, production, quality and energy savings

We use only ChemCad 7.1.2, which includes its hydraulic network simulator safety net that is included within ChemCad. More information on ChemCad process simulation software can be found here.

Personalized Technical Support

At Chemstations, we provide personalized, reliable support to every one of our users. Contacting the CHEMCAD support team doesn't involve wading through levels of representatives to get an answer. Customers are quickly connected with a friendly, knowledgeable team member who is highly proficient in chemical process simulation software.


Collaborative Approach

Chemstations is a privately owned company with a closely integrated group of developers, which lets us rapidly respond to—and even anticipate—customer needs by tapping into our industry knowledge to continually upgrade CHEMCAD's features. When changes take place in the industry, our team quickly assesses which new data and methods will be useful and viable additions to CHEMCAD. Additionally, if users require custom data or methods not currently in the CHEMCAD libraries, they can easily add the information themselves or with the guidance of the Chemstations support team.


Simulation Expertise

At Chemstations, we are industry leaders who couple our experience in simulation software with our clients' engineering expertise to form a partnership that results in optimized work flow and increased efficiency.


Flexible Platform

From complex process models to day-to-day challenges, CHEMCAD has the power and flexibility to meet user needs and exceed expectations. CHEMCAD has a tremendous range of capabilities, and because it is scalable and allows users to add features and customize as needed, it can boost productivity whether an engineer is using it to perform routine calculations or to tackle extensive projects.


Intuitive Graphical Interface

Throughout CHEMCAD's development, we have paid considerable attention to the way process engineers work. We understand the importance of designing software around the needs and goals of the users and adapting it to their workflow, instead of making them adapt to the software. To this end, CHEMCAD has been designed with an intuitive, graphical interface that enables users to do their jobs more efficiently. An open architecture allows for smooth interaction between our software and other commonly used programs. What's more, learning CHEMCAD requires less training than other simulation software, resulting in greater work efficiency and a higher return on investment.
