An Introduction to New Higee Device and Its Industrial Applications

A new HIGEE device-rotating zigzag bed (RZB) was developed in the context of process intensification. The RZB is structurally featured by a combinatorial rotor of one series of baffles attached to a rotating disk with another series to a stationary disk. The novel structure of the RZB determines its many advantages over the other HIGEE devices. The RZB is free of dynamic seal, capable of intermediate feed and simple coaxial multi-rotor configuration. These advantages qualify the RZB for utilization in continuous distillation. Three cases in different common processes were presented here to illustrate its industrial application. So the RZB is a kind of high efficiency gas-liquid contactor and opens up broad prospects for HIGEE technology commercialized in industrial continuous distillation processes.
