    Abstract: The invention is a device and method for purifying sulfur dioxide and nitrogen oxide in flue gas with an electrolysis-chemical advanced oxidation enhanced ammonia method. The device includes a thermal activation reactor, ammonium hydroxide storage tank, absorption tower, electrolytic bath and crystallization separator. The method takes raw material part of an ammonium sulfate solution that is a reaction product of ammonia and sulfur oxide in flue gas, and an ammonium persulfate solution prepared by electrolysis of an electrolytic bath as an oxidant to enhance the efficiency of purifying sulfur dioxide and nitrogen oxide in the flue gas with an ammonia method. A thermal activation reactor activates an ammonium persulfate containing solution to generate a strong oxidizing SO4.?, so that NOx and SO2 in the flue gas may be more efficiently converted into a product having higher solubleness for enhanced removal of sulfur dioxide and nitrogen oxide in the flue gas.

  • Patent number: 9968882
    Abstract: A heat transfer fluid can be used as part of a multi-phase adsorption environment to allow for improved separations of gas components using a solid adsorbent. The heat transfer fluid can reduce or minimize the temperature increase of the solid adsorbent that occurs during an adsorption cycle. Reducing or minimizing such a temperature increase can enhance the working capacity for an adsorbent and/or enable the use of adsorbents that are not practical for commercial scale adsorption using conventional adsorption methods. The multi-phase adsorption environment can correspond to a trickle bed environment, a slurry environment, or another convenient environment where at least a partial liquid phase of a heat transfer fluid is present during gas adsorption by a solid adsorbent.

  • Patent number: 9884288
    Abstract: A treatment process of a gas containing zero-valent mercury and a mercury separation system, by which the amount of an iodine compound used can be reduced when the zero-valent mercury is separated from the gas containing the zero-valent mercury by using the iodine compound. The process has a step of oxidizing the zero-valent mercury contained in the gas with a first liquid phase containing an alkali metal iodide, thereby obtaining a second liquid phase containing a divalent mercury ion and an iodide ion; a step of separating the divalent mercury ion as mercury sulfide by adjusting the pH of the second liquid phase; and a step of circulating a third liquid phase which is obtained by separating the mercury sulfide in the mercury separation step to use the third liquid phase as the first liquid phase in the mercury oxidation step.
