Description

A kind of alkali metal base nano-fluid CO2Absorbing liquid
Technical field
CO in the flue gas produced the present invention relates to combustion of fossil fuel2Removing and method for concentration, and in particular to a kind of alkali Metal-based nano fluid CO2Absorbing liquid, belongs to carbon dioxide discharge-reduction technical field.
Background technology
With society it is industrialized continue to develop, the global warming issue being on the rise caused by greenhouse gas emission into For the focus of international community's common concern.In using fossil fuel as the power generation of main energy sources, CO2Discharge capacity account for the mankind CO caused by various activities2More than the 30% of total emission volumn, is CO2Maximum single-point fixed discharge source.Therefore, study and open CO of the hair suitable for coal-burning power plant2Emission-reduction technology is to controlling and slowing down CO2The trend that discharge capacity steeply rises has highly important Strategic importance.
In numerous CO2In trapping technique, alkanolamine solution chemical absorption method (MEA) is that acquisition industrial practice is most widely used A kind of method.At present, most of power plant all use the chemical absorption method based on MEA solvents.But, MEA process exists many Weak point, such as due to oxidation, thermal degradation, occur irreversible reaction and evaporation reason cause absorbent absorption efficiency to decline, Absorbent loss, absorbent catabolite cause system corrosion, regeneration energy consumption big and initial cost and operating cost it is higher etc..Cause This, reinforcing absorbent and CO2Gas-liquid mass transfer, and then reduce the volume on absorption tower, reduction equipment and materials cost and floor space, It is the emphasis of the technical research.
In recent years, nano-fluid is notable in the effect that heat and mass field is obtained.Research finds that the addition of nano particle can To increase the thermal conductivity factor of liquid, nano-fluid can strengthen gas-liquid mass transfer effect, absorptivity of the enhancing gas in nano-fluid. Such as, Juan Qian etc. absorb CO to reduction chemical method2During resistance to mass tranfer studied, respectively with activated carbon powder End, glass microballoon, Nano-meter SiO_22MEA solution is studied for solid additive to CO2Assimilation effect, find activated carbon to CO2Inhale The enhancing efficiency maximum of receipts can improve 10% (Qian, J.；et al.,Study on CO2Absorption Enhancement by Adding Active Carbon Particles into Mea Solution.In Cleaner Combustion and Sustainable World,Qi,H.；Zhao,B.,Eds.Springer Berlin Heidelberg:Berlin,Heidelberg,2013；pp 1367-1370.).In above-mentioned document, organic principle in solution The problem of absorbent loss and the corrosion to equipment that evaporation is caused are still a sternness.
In recent years, alkali metal group solid absorbing agent carries out flue gas decarbonization technology because its absorbent stability is good, failure corrosion The low advantage of property is suggested as an innovative idea.For example, the U.S. Louisiana State University, Research Triangle Institute and Church＆Dwight has carried out correlative study, and applied for that the U.S. is special under DOE subsidy Profit：6387337B1 (2002.5.14.), 6280503B1 (2001.8.28.) etc..Domestic Southeast China University has also carried out this The correlative study of technology, has applied for Chinese patent 200810024780.8,200810122644.2 etc..But alkali metal base solid Absorbent decarburization is gas-solid reaction and heat and mass transfer performance is poor because of it, at the same the circulation of solid absorbent transport it is relatively difficult.
In summary, for solve MEA process absorbent loss and to equipment corrosion it is serious the problem of, alkali metal base solid sorbent A kind of the problem of agent reactivity is low and circulation transports difficulty, it is desirable to provide new CO2Absorbent and absorption techniques.
