Progress in Continuous Process Technology: Reactions, Post‐Process, and Development Trends

This paper reviews the research progress of the two key technologies of fine chemical continuous process—reaction continuous and post‐processing continuous. First, based on laboratory studies, the introduction covers continuous reactor technologies—such as microchannel, tubular, fixed bed, fluidized bed, and stirred tank reactors—and continuous post‐processing technologies, including separation, purification, drying, granulation, and particle separation. It also describes the coupling of reaction with separation and the integrated continuous operation of reaction and post‐processing. Second, it introduces the application of continuous process technology in the industry. Third, it explores the challenges and future development trends of continuous process technology, providing theoretical support and practical reference for process upgrading of fine chemicals. In future, the fine chemical industry will further advance toward four cutting‐edge directions: AI‐driven optimization, modular process intensification, hybrid batch‐continuous systems, and digital twin technology to promote a comprehensive transformation toward “greener, smarter, and more efficient” operations.
