Henry component setting

During the simulated separation process, the setting of the Henry component can significantly affect the calculation results. HC-1 is a property-based method that involves the application of Henry’s law, and it is suitable for dealing with low-concentration components that behave like ideal gases in solution. After selecting the Henry components, the behavior of these components will be simulated according to Henry’s law, rather than using conventional liquid-phase activity coefficient models. This usually leads to significant changes in calculations such as the solubility of gases dissolved at low concentrations. If there is a significant difference in the calculation results, it may be because: 1. The components are not suitable for simulation using Henry’s law. Not all components are suitable as Henry components; only those that exist in extremely low concentrations in the liquid phase and approximately follow Henry’s law are appropriate for this purpose. 2. Incorrect selection of physical property methods. Different property methods have varying degrees of suitability for specific systems, and it may be necessary to choose the appropriate method based on the specific circumstances. In short, whether to check the “Henry component” should be determined based on the actual behavior of the component and the specific conditions of the system. If unsure, a sensitivity analysis can be conducted to compare the results with and without the selection, or professional advice can be sought. .
