- •
Aspen plus was employed to conduct systematic evaluation for both DCMD and VMD.
- •
Transport models were developed as user customized units to simulate DCMD and VMD.
- •
The results showed the DCMD presented much lower process efficiency than VMD.
- •
The VMD system exhibits a minimal 2.5-fold higher average vapor flux than DCMD.
