How to adjust the binary interaction parameter in simulation software?
Thread Content
As the title suggests, please give some advice! Thank you! Last edited by visavis on 2009-4-14 10:53]
Find the relevant experimental data in the gas-liquid equilibrium data handbook, enter it into the software, and a reasonably accurate binary interaction coefficient can be obtained through regression
1. Directly enter the existing binary interaction parameters available (data source: literature, databases) into the software’s binary parameters. 2. Determine the binary parameters through data regression (data source: usually from gas-liquid equilibrium experiments)
For complex systems, it is very difficult to obtain the parameters related to binary interactions; regression analysis and literature searches are generally futile, as such data are hardly reported in the literature. It is therefore impossible to find interaction parameters that are applicable to your specific system. If the original poster needs these parameters, it is recommended to look for parameters related to phase equilibrium, such as volatility, and then make adjustments manually.
Thank you all for your replies; I’ll give it a try.
The binary interaction parameter is key to determining the accuracy of the calculation results produced by process simulation software; therefore, to ensure accurate and reliable results, it is advisable – if conditions permit – to conduct relevant gas-liquid equilibrium experiments for the calculations related to critical process steps, followed by data regression
