Abstract
PURPOSE: To extend the life of a device and improve removal efficiency by controlling the concn. of CaCl2 contained in the cooling water contg. CaCl2 of a process for cooling waste gases and the alkaline liquid contg. CaCl2 of a process for absorbing the sulfur oxides in the waste gases.
CONSTITUTION: A waste gas desulfurization method by a lime gypsum method using cooling water contg. CaCl2 in a cooling process and alkaline liquid contg. CaCl2 in an absorption process. At this time, the concn. of CaCl2 in the alkaline liquid is controlled in a 15W27.5% range, and the concn. of CaCl2 in the cooling water is so controlled as to be higher than 15% but not to be higher by 5% than the concn. of CaCl2 in the alkaline liquid. In this way, the concns. of the CaCl2 in the cooling water and the alkaline liquid are controlled while being mutually associated.
