环己烯水合生成环己醇过程设计与优化
Design and optimization of the cyclohexene direct hydration process
摘要
Abstract
A process used reactive distillation with isophorone as a cosolvent to produce cyclohexanol was proposed. Feeding the reactants cyclohexene and water with the cosolvent isophorone into the reac-tive distillation column(RDC), then using two rectifying columns(PDC1 and PDC2) to purify and separate the bottom product, a high-purity product of cyclohexanol can be obtained and the purity of isophorone can be recycle back to the RDC. The whole process was simulated with the NRTL thermo-dynamic equation, then it was simulated and calculated by the Aspen Plus software, a high-purity cy-clohexanol (99.9%, mole fraction) and a recyclable isophorone can be obtained finally, the heat du-ties of the system were 0.9823 kW. On the basis of the calculation, we discussed the operating condi-tions including the molar ratio of isophorone and cyclohexene, the molar ratio of water and cyclohex-ene, the pressure of column, which have effects on the cyclohexene conversion and heat duty of the system to optimize the process, and the cyclohexene conversion of the proposed process is compared with other process.关键词
