How to add new substances in ASPEN

2008-02-14View Original

Thread Content

Due to the specific requirements of a particular manufacturing process (the details are considered trade secrets and cannot be disclosed; please forgive us, experts), a new type of salt is needed. This substance is not available in the ASPEN database, and there is also very little experimental data available on it. To this end, my research approach is to first use the molecular structure for parameter estimation; however, the problem now is that it is a salt composed of cations and anions, and it is in a liquid state. How to enter it, and which thermodynamic model to choose? I earnestly request advice from all the experts; I would be extremely grateful! ! ! ! !
