SPINNING DISC REACTOR WITH SHROUD OR PLATE FOR IMPROVING GAS/LIQUID CONTACT

摘要

A reactor apparatus including a support element rotatable about an axis (1) and having a surface (2) generally centred on the axis. The surface (2) is adapted for outward flow of a thin film of a liquid phase reactant thereacross when supplied thereto as the surface (2) is rotated. The reactor apparatus is further provided with a plate or shroud (10) that covers or is coextensive with the surface (2) and defines a gap (14) between the surface and an underside of the plate or shroud (10) so as to allow a gaseous phase flow through the gap (14) and over the thin film of the liquid phase reactant. By constraining the gaseous phase flow over the liquid phase component, especially when the gaseous phase flow is countercurrent to the liquid phase flow, excellent mass transfer between the two phases can be achieved.
