48Using RSM Method to Determine Optimum Process Conditions for Flue Gas Desulfurization Through an Amine Scrubber


Abstract:

In this study the optimum process conditions for absorption of sulfur dioxide in a mixture of flue gases were determined. Using a selective amine-based absorber, a high amount of SO2 was absorbed in the scrubbing process. Some process conditions such as the temperature, concentration of the SO2, and absorber flow rate in absorption were experimentally researched. The optimized conditions were finally specified after experiments by using response surface method (RSM)experimental design method. It was observed that desulfurization of flue gas for our solvent pilot operates at the maximum performance at absorption temperature 60 C, SO2 concentration of 4000 ppm, desorption temperature of 110 °C, and the gas flow rate of 300( ( lit)/min)An efficiency of more than 99 % could be obtained by varying the parameters in which all the released SO2 gas was absorbed from the inlet flue gas. An efficiency of more than 99 % could be obtained by varying the parameters in which all the released SO2 gas was absorbed from the inlet flue gas; an achievement that is much favorable for industrial purposes.
