Experimental Study Of AEEA Absorption Solution Development And Process Optimization

Due to the increasing emissions of greenhouse gases carbon dioxide,resulting the increasingly serious environmental problems.The recovery technology of flue gas in power plants had been developed adequately.The recovered carbon dioxide can be used in enhance oil recovery directly.Amine solutions having the characteristic of quick absorption?larger absorption capacity and simpler regeneration which made it become the hot point in the recovery of carbon dioxide.The experimental by using AEEA?ME A?DEA?DIPA?TEA?AMP?MDEA solutions and theirs mixed solutions,to study absorption and desorption characteristic of carbon dioxide in simulated flue gas.In the experimental study,we comparative and analysis the relationship of absorption rate?absorption capacity?desorption rate?desorption capacity with time and the reaction heat relations.Discovered in the single-amine solution,AEEA solution is the best single-amine solution,and in the two-amine solution,quality fraction ratio of 10:1 of AEEA-DIPA solution is the best two-amine solution.No matter single-amine solution or two-amine solution,absorption capacity is always increase fast in the begining of experiments,then increasing slowly.The variation of absorption rate and desorption rate to increase first and then decrease.In the next experiment of defoamers,comparative the foaming height and defoaming time,we can obtained the organic silicon defoamer is the best.On the basis of small scale experiment,we use a set of 300Nm3/d flue gas treatment capacity pilot experimental apparatus to study of continuous carbon dioxide capture,based on fuel gas?solution flow?desorption temperature and desorption energyand et al.Discovered the absorption characteristics of AEEA single-amine solution and AEEA-DIPA two-amine solution have consistent with the conclusion of small scale experiments.
