CHEMCAD's CC-THERM module has offered embedded rigorous modeling of heat exchangers for many years. There is no need to toggle to another tool and import the data. CC-THERM is an existing tool in CHEMCAD and uses the data within your current simulation.
Why is this CC-THERM in CHEMCAD a valuable tool?
In many situations, general heat transfer calculations for exchangers are sufficient. In other circumstances, you really need a more rigorous model. Let's look at a few examples where rigorous heat exchanger modeling can help you obtain faster, more accurate results.
Can your existing heat exchangers handle the increased flow?
Imagine you are asked to find a way to improve throughput. Can your existing heat exchangers handle the increased flow? You can use CHEMCAD to:
- Create a Rating case in CC-THERM
- Enter specifications for the existing exchanger (TEMA type, number of tubes, baffles, etc.) and get the flows, temperatures, and pressures to match current conditions.
- Increase the flow in the model to see if you exceed any constraints on the exchanger.
Fouling Rating calculation in CC-THERM
Suppose there's a concern with fouling in a particular stream. You can use a Fouling Rating calculation in CC-THERM to find the fouling rate that allows the model to fit reality. Then increase the flow in the model as before, to determine whether the existing exchanger will be sufficient.
Is the exchanger you have limiting your throughput?
Engineers can use a Design calculation in CC-THERM to model a replacement exchanger. Use the specifications of the existing exchanger to create your initial estimates, since you know these specs are close to your requirements. Now you can approach your heat exchanger manufacturers with a much clearer picture of what you need and what their proposed design should look like.
CHEMCAD training for CC-Therm
CC-Therm is included in your CHEMCAD subscription license. Contact us to discuss CC-THERM and the training options available to your team. We will be happy to schedule a virtual or on-site training to accommodate your team and their learning styles.
