摘要

连续反应器中的污垢是特种聚合物工艺强化过程中的一项重大挑战。连续搅拌罐反应器（CSTR）中的污垢极少，而管式反应器中的污垢却很严重，有时甚至会导致完全堵塞。因此，了解导致沉积物形成的工艺和设计条件至关重要。在这项工作中，我们测试了几何形状、混合元件、新型涂层和超声波对聚乙烯吡咯烷酮聚合管式反应器的影响。

Fouling During Polymerization in Different Continuous Reactor Setups

Fouling in continuous reactors presents a significant challenge in the process intensification of specialty polymers. While in continuous stirred tank reactors (CSTRs) fouling is minimal, tubular reactors experience severe fouling, sometimes leading to complete blockage. Therefore, it is crucial to understand process and design conditions contributing to deposit formation. In this work, the impact of geometry, mixing elements, novel coatings, and ultrasonic waves are tested on tubular reactors for the polymerization of polyvinylpyrrolidone.
