摘要：

A new method of water recovery from flue gas with hollow micro-nano porous ceramic composite membranes has been put forward in order to deal with the evaporated wastewater from thermal power plants. The feasibility of this method has been investigated in theory, and ceramic membranes of different pore sizes in selective layer have been prepared for experiments. The achieved results indicate that the ceramic membrane with selective layer of 20 nm pore size is appropriate for different flue gas conditions. The amount of recovered water augments with the increasing relative humidity of gas. When the temperature of flue gas reaches 70 degrees C, the amount of recovered water is above 1 L/m(2) h and the recovery ratio can be up to 55%. This method has great potentiality in the application of water recovery from flue gas in thermal power plants. (c) 2017 The Korean Society of Industrial and Engineering Chemistry.
