Question:

In the production of dimethyl carbonate from methanol, it is necessary to separate methanol from formal (also known as methylal—C₃H₈O₂). However, an azeotrope exists between these two components. Using a process simulator, examine the equilibrium curves (x-y plots) between 100 kPa and 1000 kPa to determine a strategy for purifying these two components. Compare your results for the following thermodynamic packages for the K-value:

1. Ideal

2. NRTL

3. UNIFAC

4. SRK
