摘要： PROBLEM TO BE SOLVED: To provide a method for treating a tail gas that can remove mercury and enables efficient operation and continuous performance without having a bad effect on an apparatus in a system. SOLUTION: The method for treating mercury in a tail gas includes subjecting the tail gas containing a nitrogen oxide, a sulfur oxide and mercury to reduction denitration in the presence of a solid catalyst after the addition of a chlorination agent and then performing wet desulfurization with an alkaline lean liquid. A predicted value of an inlet mercury concentration before the reduction denitration is calculated based on the mercury concentration in the tail gas measured after the wet desulfurization. The feed rate of the chlorination agent to be added before the reduction denitration is controlled based on the amounts of change of the above predicted value and a standard inlet mercury concentration by the method for treating mercury in a tail gas and a treatment system for the tail gas is provided.

摘要： PROBLEM TO BE SOLVED: To provide a flue gas treating method in which the concentration of ammonia in flue gas after treatment is kept low by using a small-sized gas- liquid contact device provided with both a concurrent flow absorber and a countercurrent flow absorber. SOLUTION: A gas-liquid contacting device is provided with an introducing side tank 21 into which a liquid absorbent is fed, a concurrent flow introducing side absorber 2 installed extended upward from the introducing side tank 21 and for subjecting untreated flue gas to gas-liquid contact with the liquid absorbent in the introducing side tank 21, a bring-out side tank 22 arranged adjacent to the introducing side tank 21 and into which a liquid absorbent is separately fed, and a countercurrent flow bring-out side absorber 3 installed extended upward from the bring-out side tank 22 and for introducing flue gas brought out from the introducing side absorber 2 to subject it to gas-liquid contact with the liquid absorbent in the bring-out side tank 22. By using the gas-liquid contracting device, fly mist is removed from flue gas before flowing into the bring-out side absorber 3 to return it to the introducing side tank 21, and also pH of the liquid absorbent of the other absorber is controlled to a low value (for example, 4.0-5.0) at which ammonia is hardly diffused into flue gas.

摘要： PURPOSE: To stably keep a high desulfurization rate in low cost by feeding an alkali agent by a feed control means when an unsteady operation state such as the lowering of pH or the increase of impurities in exchaust gas is developed. CONSTITUTION: When it is detected that the pH of the slurry in an absorbing cylinder 11 detected by a pH detector 38 becomes lower than a preset objective value of the operation state of a gas-gas heater(GGH) 8 or a dust collector 2 becomes an unsteady operation state such that impurities in the untreated flue gas flowing into an absorbing tower 11 increase, a feed means 110 feeding an alkali agent into the slurry is operated in a moment by the control of a feed control means 140. The alkali agent is automatically fed in the slurry in a constant flow rate until the pH of the slurry in the absorbing tower 11 rises to an objective value and the unsteady operation state is completed. By this constitution, a high desulfurization rate is stably kept.
