ASPEN butyl acetate-butanol-water azeotropy problem
Thread Content
I would like to ask everyone for help. In the solvent manual, I found that the azeotropic composition of water-butanol-butyl acetate is 29:8:63 on a molar basis. However, using ASPEN, the azeotropic composition indicated 71:10:19. There is a significant difference between these values. If anyone has used other software, could they please help check this? How do I modify the parameters for this issue?
Using ASPEN, I determined that the azeotropic composition of water-butanol-butyl acetate is 69:8:23 on a molar basis, using the NRTL-RK and VLL methods.
