【摘要】 利用ASPEN PLUS软件和醋酸甲酯水解催化精馏工艺研究的小试数据,对PVA生产中醋酸甲酯水解工序的全流程进行了模拟计算,并给出了中试结果。模拟计算结果表明:采用催化精馏工艺,可使流程中物料循环系数大大降低;满足原分离指标的条件下,分离设备的规模可减少;不改变分离设备的条件下,仍可达到原来的分离要求,而且能节约大量能量。更多还原

【Abstract】 Aspen Plus software and experiment data of hydrolyzing methyl acetate by catalytic distillation technology were used to simulate the whole hydrolysis section, the results of the pilot plant scale tower were presented. The results showed, firstly, the recycle coefficient of the process can be reduced greatly in recovering methyl acetate by catalytic distillation technology; secondly, the scale of some equipment can be decreased without decreasing the separation level of these equipment; thirdly, keeping the scale of equipment, the requirement of separation can still be satisfied and energy can be saved at the same time, good economic results can be achieved .更多还原
