In response to the worldwide need for more sustainable chemical processes, distillation became target of major efforts for efficiency improvement. Leveraged by process intensification, several technologies have been proposed to reach a more compact, safer, and less energy-intensive equipment. Falling film columns were intensively used for heat and mass transfer research in last century. Noteworthy, studies proposing the falling film technology in distillation condition highlighted numerous advantages, such as low residence time and simple constructive structure when compared to conventional distillation, as well as high transfer rates due to the small thickness that flows in longitudinal direction of the distillation wall. Therefore, this review brings a historical perspective of theoretical and experimental works as well as deposited patents on falling film distillation from the beginning of 20th Century to present. Theoretical background and conceptual aspects related to efficiency improvement and process intensification were deeply discussed, aiming to guideline future perspectives in chemical separations.

湿壁塔中降膜蒸馏的背景综述:从基础到强化技术

为了响应全世界对更可持续的化学过程的需求,蒸馏成为提高效率的主要努力的目标。利用过程增强,已经提出了几种技术来达到更紧凑,更安全和能耗更低的设备。降膜柱在上个世纪被广泛用于传热和传质研究。值得注意的是,提出在蒸馏条件下使用降膜技术的研究突出了许多优点,例如与常规蒸馏相比,停留时间短,构造结构简单,并且由于沿蒸馏壁纵向流动的厚度较小,因此传输速率较高。 。因此,这篇综述从20世纪初到现在带来了理论和实验工作的历史观点,以及有关降膜蒸馏的沉积专利。深入讨论了与效率提高和过程强化相关的理论背景和概念方面,旨在为化学分离提供指导。
