Abstract


In view of the increasingly serious problem of a large number of CO2 emissions caused by the environment , and the CO2 potential resources , to develop a new and efficient organic amine solution enriched flue gas CO2, increasingly subject to the attention of the world . The characteristics of this thesis, through the activation of sodium glycinate (SG) solution to absorb CO2 , preliminary study of the interaction mechanism and kinetics , as well as the rich liquid renewable carry out the experimental greenhouse gas enrichment technology and its industrial applications accumulated a certain data and theoretical basis . Stirred tank reactor , the total concentration of 1.0kmol · m-3 SG PZ mixed solution to absorb the effect of CO2 inspect. Determination of the mixed solution of the reaction rate of the absorption of CO2 with the relationship of change in the amount of time and absorption , to obtain a single solution to the absorption properties of the mixed solution is superior to the MEA and other conventional organic amines and SG . The effects of the CO2 absorption , it is recommended that the temperature of the mixed solution of 40-C for optimal absorption temperature of the mixed solution . Of Investigation PZ content on the uptake of the obtained PZ SG solution was added in small amounts help to improve the absorption rate . Promoting absorption interactions obtained SG and PZ present in the solution by absorption performance comparison of a mixed solution of its single component . Add SG solution 0.1,0.2,0.3 kmol · m-3PZ, load 0.1 , the enhancement factor is able to maintain more than 80 % of the zero load . Combined with the experimental results , determine the reaction kinetics of the CO2 absorption of the mixed solution of SG PZ regions intends a rapid reaction . Constant temperature heating reproducing apparatus magnetic stirring , the mixed solution of SG PZ inspect absorb CO2 rich liquid regeneration performance . Determination of 363 K ~ 403 K under the influence of the regeneration temperature of the regeneration efficiency and regeneration time to determine the optimal regeneration temperature is 388 K . Compare the total concentration of 1.0 kmol · m-3 mixed solution regeneration , to found 0.9kmol · m - 3 SG 0.1 kmol · m -3 PZ highest regeneration efficiency of the mixed solution of 91.0% , higher than the SG single solution 2.6% . The results showed that in the SG solution , adding less than 20% of the PZ, can effectively improve the CO2 absorption and regeneration performance . Superior absorption rate and regeneration efficiency that the SG PZ mixed solution is a great prospects for industrial applications of CO2 absorbent .
