Abstract
IN AN EXHAUST GAS DESULFURIZATION PROCESS WHEREIN SULFUR OXIDES AND HCI PRESENT IN EXHAUST GAS ARE ABSORBED INTO A TREATING FLUID CONTAINING A MG-BASED DESULFURIZING AGENT, AND THE TREATING FLUID IS CIRCULATED THROUGH DESULFURIZATION (1), OXIDATION (3) AND DOUBLE DECOMPOSITION (4) STEPS TO FIX AND REMOVE THE SULFUR OXIDES IN THE FORM OF GYPSUM DIHYDRATE BY ADDING CALCIUM HYDROXIDE TO THE TREATING FLUID AND, AT THE SAME TIME, TO REGENERATE THE TREATING FLUID, A PORTION OF THE DESULFURIZATION STEP TREATING FLUID IS ADDED TO THE TREATING FLUID OBTAINED IN THE DOUBLE DECOMPOSITION STEP SO AS TO REMOVE CALCIUM IONS THEREFROM, AND THE TREATING FLUID THUS OBTAINED IS THEN RECYCLED TO THE DESULFURIZATION STEP (1). THIS PROCESS MAKES IT POSSIBLE TO EFFECT EXHAUST GAS DESULFURIZATION ACCORDING TO THE DOUBLE ALKALI TECHNIQUE WHILE USING SIMPLE AND SMALL-SIZED EQUIPMENT AND TO MAINTAIN STABLE OPERATION WITHOUT SCALE DEPOSITION IN THE DESULFURIZATION TOWER.FIGURE 3
