Development of Methods for Intensification of Reaction and Separation Processes Based on Phenomenological Dynamics

这项研究的目的是为“过程强化”的装置设计和操作提供系统的方法。首先，我们从现象学的角度研究了三个主题：(A)开发微空间的创新装置，(B)替代能源的利用(C)材料加工的新操作方法。然后讨论了包括反应系统、分离系统和公用工程系统在内的强化过程系统的建模方法和仿真方法。我们在以下11个主题方面取得了系统的成果：(1)利用交变电场进行催化反应过程装置的紧凑设计(2)利用微空间和超声场提高反应/分离过程的效率(3)使用电加热催化剂进行非稳态操作的反应器的设计(4)使用分叉微通道开发分馏通道(5)使用间接超声辐射的聚合系统的动态操作(6)具有微通道的超滤组件的操作(7)利用微流体动力学提高反应/分离过程的效率(8)通过以下方法提高反应/分离过程的效率时空操作(9)强制温度循环操作控制丙烯氧化(10)喷雾脉冲操作对异丙醇脱氢最佳操作条件的研究(11)基于连续乳液聚合过程中反应/凝聚动力学的粒度控制指出传统化学工程中的“单元操作”为基础的工艺设计技术，仅靠简化方法很难实现过程强化。由此可以得出结论，“多视点”(或“多范围”)建模与仿真将成为推动过程强化技术发展的必要手段。

The purpose of this study is to show systematic methods for design of devices and their operation for "process intensification". First we investigated on three themes from the viewpoint of phenomenology : (A) Innovative devices exploiting micro space, (B) Utilization of alternative energy (C) New operation methods for material processing. Next, modeling methods and simulation methods for intensified process systems, which included reaction systems, separation systems and utility systems, were discussed.In the term of this project, we achieved results in the following eleven themes for systematic approach to design of devices and their operation.(1) Compact design of a device for catalytic reaction process using alternating current field(2) Enhancement of efficiency of reaction / separation process using micro space and ultrasound field(3) Design of a reactor using an electrically heated catalyst for unsteady operation(4) Development of channels for fractionation using bifurcating microchannels(5) Dynamic operation of polymerization system using indirect ultrasonic irradiation(6) Operation of ultrafiltration module with microchannels(7) Precise separation using micro fluid dynamics(8) Enhancement of efficiency of reaction / separation process by spatio-temporal operation(9) Control of propylene oxidation using forced temperature cyclic operation(10) Study on optimal operational conditions for de-hydrogenation of 2-propanol using a spray pulse operation(11) Particle size control based on reaction / coagulation dynamics in a continuous emulsion polymerization processMoreover, it was made clear that the process intensification could not be achieved easily only by reduction approach for process design technology, which was based on "unit operation" embraced in traditional chemical engineering. Then we could conclude that "multi-viewpoint" (or "multi-scope") modeling and simulation would become necessary for propelling development of process intensification technologies.
