| Outline of Final Research Achievements |
Two types of compact separation devices were developed utilizing rapid dynamics realized by micro channels.
One of them is a compact continuous distillation device. The device consists of two layers of plates holding a plate-shaped narrow space in between, which is used as a micro channel. Fluids in a channel reach a vapor-liquid equilibrium rapidly due to an efficient contacts between phases. The continuous separations of water-ethanol and toluene-ethyl acetate were examined, and 15 cm sized device realized the compatible ability with 3-5 stages multiple distillation columns by controlling the temperature gradient on the plates.
The other device is a continuous extraction and re-extraction device. The stable segmented flow with three phases of aqueous A - organic - aqueous B - organic was realized by controlling the flow rates of fluids with solenoid valves, and some ions contained in an aqueous A were successfully concentrated to the other aqueous phase B via organic phases.
