摘要: The concept of process intensification (PI) has absorbed diverse definitions and stays true to the mission-"do more with less", which is an approach purposed by chemical engineers to solve the global energy & environment problems. To date, the focus of PI has been on processes mainly involving vapor/liquid systems. Based on the fundamental principles of vapor-liquid mass transfer process like distillation and absorption, there are three strategies to intensify interphase mass transfer:enhancing the overall driving force, improving the mass transfer coefficient and enlarging the vapor-liquid interfacial area. More specifically, this article herein provides an overview of various technologies to strengthen the vapor-liquid mass transfer, including application of external fields, addition of third substances, micro-chemical technology and usage of solid foam, with the objective to contribute to the future developments and potential applications of PI in scientific research and industrial sectors.
