Abstract: The improvement research of absorption column for flue gas desulfurization (FGD) and some new FGD reactors, such as falling film reactor, impinging stream reactor and rotating packed bed (RPB), is reviewed in details. The advantages and disadvantages of each device are compared. It is pointed out that the intensification technology of chemical engineering process is a new approach to solve the problem of low mass transfer efficiency and high investment costs for traditional column devices. Therein the application of RPB in wet FGD is of high value. The relevant research direction for industrial application is to develop a RPB that can deal with higher flow rate and intensify gas phase mass transfer process.
