METHOD FOR ANALYZING CONCENTRATIONS OF CARBAMATE, THE BICARBONATE, AND THE CARBONATE IN A CARBON DIOXIDE ABSORBENT, CAPABLE OF QUANTITATIVELY ANALYZING SPECIES FORMED IN AN ABSORBENT AFTER ABSORBING THE CARBON DIOXIDE

摘要

PURPOSE: A method for analyzing concentrations of carbamate, the bicarbonate, and the carbonate in a carbon dioxide absorbent is provided to obtain a speciation distribution according to a sort of an amine, a concentration of an amine solution, a reacting temperature, and an absorption amount of carbon dioxide and to decide a reacting mechanism of the amine solution under a specific condition.;CONSTITUTION: A method for analyzing concentrations of carbamate, the bicarbonate, and the carbonate in a carbon dioxide absorbent is as follows. An absorbent absorbing the carbon dioxide of a specific amount is prepared. The absorbent is dissolved in a D2O and manufactures a sample. Concentrations of carbamate, the bicarbonate, and the carbonate in the sample are analyzed by using a nuclear magnetic resonance analyzing device. The absorbent is selected from a group being composed of the alkanolamine, annular amine, chain type amine, amino acid salt and alkaline salt. The absorbent is MDEA(Methyl diethanol amine) or AMP(adenosine monophosphate).;COPYRIGHT KIPO 2012
