This paper focuses on the conceptual design of a quenching system to separate the water produced in a glycerol-based acrylic acid production process. In the glycerol-based process, acrylic acid is produced through fermentation and dehydration, and a large amount of water is generated. Thus, an effective way to separate water from acrylic acid is essential. We investigate a process scheme for quenching systems that separates the water generated from these reactions. The liquid–liquid extraction process is applied to separate water for high purity acrylic acid production. The selection of the solvent in extraction process is important so we compared several representative solvents, then results is that toluene is the most suitable solvent. As a result, a conceptual design using toluene as a solvent was suggested, and the proposed process using a quenching system to separate the water in two steps was investigated. The sensitivity analysis and economic assessment of the proposed process resulted in a 46.0 wt% reduction in the total flowrate of the subsequent processes, and reductions in the capital and operating costs by 52.0% and 39.3%, respectively.

本文着重于淬火系统的概念设计，该系统用于分离甘油基丙烯酸生产过程中产生的水。在基于甘油的方法中，通过发酵和脱水产生丙烯酸，并且产生大量的水。因此，从丙烯酸中分离水的有效方法是必不可少的。我们研究了用于淬灭系统的工艺方案，该工艺方案将从这些反应中产生的水分离出来。液-液萃取过程用于分离水以生产高纯度丙烯酸。在萃取过程中选择溶剂非常重要，因此我们比较了几种代表性的溶剂，然后得出甲苯是最合适的溶剂。结果，提出了使用甲苯作为溶剂的概念设计，并研究了使用淬火系统将水分两步分离的拟议方法。对拟议工艺的敏感性分析和经济评估导致后续工艺的总流量减少了46.0 wt％，资本和运营成本分别减少了52.0％和39.3％。
