Abstract: The objective of this study is sulfur dioxide adsorption process withdifferent adsorbent properties in a plug flow reactor. Selected adsorb&s arecalcium oxide, calcium carbonate, activated carbon and silica gel. The studyfocuses on types of adsorbents, flow rate and the inlet temperature of gaseswhich will have influences on the adsorption effectiveness of sulfur dioxide. Thecosts of different adsorbent raw material used per a unit weight of sulfurdioxide adsorbed are compared and the least cost of the raw material isdetermined.The results of the study show that calcium oxide and calcium carbonatewhich adsorb suifur dioxide via a chemical reaction gives the highest adsorptionvalues than the nonpolar and polar agents such as activated carbon and silicagel. The adsorption values of calcium oxide, calcium carbonate, activated carbonand silica gel are 0.097, 0.094, 0.092 and 0.091 grams of sulfur dioxideadsorbed per grams of adsorbent, respectively.The optimum flow rate of the inlet gas that yiilds the highestadsorption values are between 1 .O 1.5 cubic feet per hour. For the highervalues of gas flow rates in a range of 1.5 - 2.0 cubic feet per hour, theadsorptivii decreases as the gas Row rate increases, For the effect of inlettemperatures on the adsorption properties the results show that calcium oxide,calcium carbonate and activated carbon adsorptivities are not affected bytemperatures increased from 30 - 36 ‘C. However, only the silica gel that givesthe adverse result when the temperature has increased at this range. Theadsorptivii of silica gel decrease as the inlet gas temperature increases.The adsorption effiiiency of a plug flow reactor can be illustrated byusing different parameters, such as the gas flow rates and the inlettemperatures. The results show that the gas flow rate at 1 .O cubic feet per hourgives the maximium adsorption efficiency. However, the effect of inlet gastemperatures on the sulfur dioxide adsorption capacities are not distinguishable.The cost comparisons of different adsorbents use per 1 gram of sulfurdioxide adsorbed found to be 0.02, 0.04, 0.06 and 1.21 Bath for calcium oxide,calcium carbonate, activated carbon and silica gel respectively. The results showclearly that calcium oxide and calcium carbonate should be recommended foruse as adsorbent materials in the sutfur dioxide adsorption process.
