What property methods are used for systems containing acetic acid?
Thread Content
The system contains acetic acid, with the rest being organic polar substances. I wonder if systems containing acetic acid have any special requirements regarding the choice of properties evaluation methods?
HAc undergoes association; property methods such as NTRL-HOC or UNIQ-HOC are generally suitable. For special cases, a method of regressing physical properties based on the interaction parameters between various substances is required. It is recommended to first use the property methods provided by ASPEN PLUS for simulation to observe the actual operating conditions, before deciding whether it is necessary to seek property data.
What does it mean for aggregation to occur? 2# llbear
For systems containing acetic acid, meteoric association must be taken into account; for other components in the system, property methods such as NRTL-HOT can be used
Thank you. Next, I also plan to simulate the acetic acid system, so I need to prepare some preliminary knowledge first
It is recommended to use activity coefficient equations such as NRTL or Wilson for the vapor phase; if the acetic acid content is high, the HOC equation is advised
