| Research Abstract |
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 process
Moreover, 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.
