《Extractive Distillation of Methyl Acetate-Methanol Azeotrope Using [DMIM]DMP as Solvent》
The DMSO process is shown in Figure 3b.The difference between this process and[DMIM]DMP process indicated that C2 was operated at atmospheric pressure.The DMSO process was also optimized to obtain the process parameters by using the sensitivity analysis tool similar to that adopted to the[DMIM]DMP process.The fresh solvent DMSO must be supplemented at a flow rate of 0.239 kg/h.The optimization results and the energy consumption of DMSO process and[DMIM]DMP process are listed in Table 4.It can be seen that the mass flow of solvent used in the[DMIM]DMP process was only 11%of that used in the DMSO process and the amount of makeup solvent needed by the[DMIM]DMP process was much less than that used in the DMSO process.The total energy consumption of the[DMIM]DMP process was only 37%of that in the DMSO process.The[DMIM]DMP process required fewer theoretical plates and smaller reflux ratio.Compared with the DMSO process，the[DMIM]DMP process showed lower energy consumption and less equipment investment cost.
