Abstract
PURPOSE:To measure the saturation degree of the absorbing liquid quickly and simply and to prevent the blocking of the desulfurization device by taking out a part of the absorbing liquid from a circulating absorption system, and measuring the difference between the temperature at which crystals begin to deposit when the absorbing liquid is cooled after carbon has been separated and the temperature at which the absorbing liquid is taken out. CONSTITUTION:A part of absorbing liquid is taken out of the circulating system of the smoke desulfurization device wherein the absorbing liquid whose main components are MgO, Mg(OH)2, MgCO3, and the like. The temperature at the time of taking out is measured. The temperature, at which carbon in the taken out liquid is separated, the liquid is separated, and the crystals begin to deposit, is also measured. The saturation degree of the absorbing liquid is measured from the difference in both temperatures. The measurement can be performed simply and quickly. In the case, when the temperature of the absorbing liquid in the circulation system is 55- 60 deg.C, and the measured temperature difference is larger than 10 deg.C, the operational condition is safe. If the temperature difference is 6-10 deg.C, water should be flowed in or pH should be lowered. If it is 3-5 deg.C, there is a danger of blocking. Therefore, the supply of the absorbing agent should be immediately stopped, while the absorbing liquid should be taken out of the system, and large amount of water should be poured into the system.
