Description

The device of the micro-ammonia in the gas that removal is discharged in utilizing the collecting carbonic anhydride operation of ammoniacal liquor
Technical field
The present invention relates to a kind ofly remove the device that the micro-ammonia that emission gases led out behind the carbon dioxide is removed from the mist that contains carbon dioxide for the carbon dioxide absorption separation circuit that utilizes ammoniacal liquor; In more detail, relate to a kind of in utilizing the collecting carbonic anhydride device of ammoniacal liquor, use a spot of water and prevent the ammonia loss, in capturing device, utilize the non reversibility chemical reaction to remove to be included in the flue gas and the ammonia that leaks and reduce as far as possible ammonia content in the emission gases, remove the device that is utilizing the micro-ammonia in the gas that discharges in the collecting carbonic anhydride operation of ammoniacal liquor.
Background technology
In recent years, people begin to recognize the seriousness of global warming phenomenon, and countries in the world are sought the countermeasure to greenhouse gases painstakingly, and one of the biggest factor of such global warming is a carbon dioxide.
Such carbon dioxide produces when combustion of fossil fuel, as being used to capture or the method for separating carbon dioxide, uses absorption process usually, as such absorption process, Physical Absorption method and chemical absorption method is arranged.
As chemical absorption method; Following absorption process is arranged: select the excellent amine aqueous solution of the absorbability of carbon dioxide as absorbent, in the absorption tower, behind the chemical absorbing carbon dioxide; In removing tower, changing temperature separates; But using like this under the situation of amine as absorbent, the shortcoming of deterioration that exists the performance of the absorbent that uses significant amount of energy, causes by the sour gas in the flue gas to descend to cause by oxygen and so on, and as the price is rather stiff of the amine of absorbent.
In recent years, as the method for absorbent a lot of researchs are arranged to utilizing ammoniacal liquor, and proved conclusively on a large scale.
Compare with MEA (MEA) aqueous solution, the carbon dioxide absorption amount of ammoniacal liquor is about 3 times, and regenerated heat is about 1/3, therefore, is using under the situation of ammoniacal liquor as carbon-dioxide absorbent, and the scale of device diminishes, and can reduce energy usage.In addition, under the situation of ammoniacal liquor, have following advantage: price is merely 1/10 of ammonia, does not exist the performance of the absorbent that is caused by the sour gas in the flue gas to descend, and does not also have the deterioration that causes because of oxygen.
But because the vapour pressure of ammonia is high, thereby if there is not other wash mill, the amount of the ammonia that then leaks from the upper end, absorption tower is quite big, and ammonia belongs to global regulation gas, therefore is difficult to realize clean collecting carbonic anhydride equipment.
Thus, developed utilize water with the ammonia stripping that leaks, to water used in this process heat and reclaim ammonia, method and apparatus that the water that will remove ammonia is reused for ammonia stripping.
By such technology of the applicant exploitation Korean Patent 10-70399 number and 10-0836709 number etc. are arranged.
They are by ammonia stripping tower (perhaps absorption tower), and it is to be used for removing from flue gas carbon dioxide that separates and the unit of having removed the ammonia that is contained the flue gas of carbon dioxide; With the formations such as ammonia recovery tower that are used to reclaim the ammonia that is washed; The ammonia stripping tower that constitutes like this is in order to satisfy the emission intensity standard value; The clearance that needs to supply with a large amount of water and improve ammonia; Consume significant amount of energy at the ammonia recovery tower that is used for reclaiming ammonia thus, and the problem that exists the energy efficiency of collecting carbonic anhydride operation to descend.
In addition, such method is limited to the micro-ammonia of removing in the treated flue gas.
