Reactive distillation is a cost-effective chemical engineering process intensification method which involves the reaction and separation simultaneously in a single unit. Previously, Propionic Acid has been purified using n-Butanol as an entrainer in a batch setup using reactive distillation in the presence of a cation exchange resin catalyst called Amberlite. The final product is n-Butayl Propionate and it can be subjected to reversible reaction to get pure propionic acid. The extension of reactive distillation in a semi-batch setup to purify Propionic Acid is yet to be studied. In the present work, the Propionic Acid is purified using n-Butanol (nB) as an entrainer through the esterification process to occur in a semi batch reactive distillation unit. The flow rate effect along with the concentration of acid at different weight percentages of catalyst are carried out. As nB possesses the lightest weight in the mixture, it volatilizes to the topmost section of the distillation column during the operation. By means of distillate, it can be eliminated from the reactive system in a typical setup of conventional batch reactive distillation (CBRD) column following which the conversion of PA gets inhibited. Hence, through the approach of semi-batch reactive distillation (SBRD) the purity of acid is verified. Contrarily in the reactive mixture, as water is the second lightest
反应蒸馏是一种具有成本效益的化学工程工艺强化方法,在一个装置中同时进行反应和分离。在此之前,丙酸的提纯是以正丁醇为夹带剂,在名为 Amberlite 的阳离子交换树脂催化剂存在下,采用反应蒸馏法进行批量生产的。最终产品为丙酸正丁酯,可通过可逆反应得到纯丙酸。将反应蒸馏扩展到半批次装置中以提纯丙酸的方法还有待研究。在本研究中,使用正丁醇(nB)作为夹带剂,通过在半间歇反应蒸馏装置中发生的酯化过程提纯丙酸。在催化剂重量百分比不同的情况下,对流速和酸浓度的影响进行了研究。由于 nB 在混合物中重量最轻,因此在操作过程中会挥发到蒸馏塔的最顶端。在传统的间歇反应蒸馏塔(CBRD)的典型设置中,通过蒸馏物可以将其从反应体系中去除,从而抑制 PA 的转化。因此,可以通过半批次反应蒸馏(SBRD)的方法来验证酸的纯度。相反,在反应混合物中,由于水是第二轻的
