第三章理想流动反应器 第一节流动模型概述 ·平推流反应器 Piston Flow Reactor (PFR) 活塞流模型或理想置换模型 This type of units is illustrated in the following figure. This reactor consists of a tube inside which the reaction medium flows. This makes it the simplest structure conceivable for a continuous operation system. The heat exchange necessary to add heat to the system or to remove it generally occurs across the tube wall第三章 理想流动反应器 第一节 流动模型概述 • 平推流反应器 Piston Flow Reactor (PFR) 活塞流模型或理想置换模型 This type of units is illustrated in the following figure.
