Phase equilibria, simulation

In the same vein, a configurational sampling technique was described that allows phase equilibria simulation of alkanes with longer chains. Several systems of linear alkanes at various temperatures were studied, and results compared to those from more conventional techniques show good agreement. [Pg.160]

As noted in Section 13.5. the results provided for the toluene hydrodealkylation process are based on the SRK model for both enthalpy and phase equilibria. Simulate the benzene column (T-101) with the 20. PR model instead, using the shortcut simulation module and the specifications given in Table 13.1 and the conditions of feed stream (10) given in Exanple 13.2. Determine the BIPs for the PR model used by the simulator. Rerun the simulation with all the BIPs set to zero. Conpare the results. [Pg.439]
