摘要：作业安全和工艺安全是实行化工生产总体安全的不可缺少的两个保障。设计完善的工艺系统往往具有较高的可靠性和安全性，存在缺陷的工艺系统，即使操作人员精心操作也一样难免出现工艺安全事故。小型化工生产形式广泛存在于化学制药、农药生产、染料颜料、化工助剂、食品生产等行业，这些生产过程的工艺具有流程长、间歇式、剩余物成分杂、自动化控制程度低、人工就近控制、就近监视等明显特点，其生产工艺中通常设计有回收溶剂或获得产品的蒸馏工艺，该工艺过程涉及加热、冷凝、冷却等单元，是一个比较复杂的过程，其危险性较大，现予初步分析。

摘要：In many chemical processes, large amounts of wastewater containing butanol and isobutanol are *** that n-butanol-isobutanol-water can form triple azeotrope, high-purity butanol cannot be recovered from the wastewater by ordinary distillation. To economically and effectively recover butanol from this kind of wastewater, 1,4-butanediol is selected as an extractant to break the formation of the azeotropes, and a doubleeffect extractive distillation process is proposed. The conceptual design of the proposed process is accomplished based on process simulation. With the proposed process, the purity of recovered butanol and water is greater than 99.99 wt%. In comparison with the conventional azeotropic distillation process, economic analysis shows that the operating cost of the proposed process is lower: when the capacity of wastewater treatment is 100 t·h^(-1), the total operating cost decreases by 5.385 ×10~6 USD per year, and the total annual cost of the new process decreases by 5.249 ×10~6 USD per year. In addition, in the extractive distillation system, variable effects on separation purities and cost are more complex than those in the ordinary distillation system. The method and steps to optimize the key variables of the extractive distillation system are also discussed in this paper and can provide reference for similar studies.

摘要：In this paper, the novel control structures of differential pressure thermally coupled reactive distillation process for methyl acetate hydrolysis were proposed. The RadFrac module of Aspen Plus was adopted in the steady-state simulation. Sensitive analysis was applied to find the stable initial value and provide a basis for the improved control structure design. The Aspen Dynamics software was adopted to study the process dynamic behaviors, and two novel control structures provided with feed ratio controllers and sensitive tray temperature controllers were proposed. The reflux ratio controllers were applied in the improved novel control structures. Both control structures abandoned the composition controllers that were replaced by simpler controllers with which the product purity could meet the specification requiring under a ± 20% disturbance to the total feed flowrate/MeAc composition.
