Preparation method of novel ternary compound organic amine medicament capable of absorbing CO2 with little water

Abstract

The invention relates to a preparation method of a novel ternary compound organic amine medicament capable of absorbing CO2 with little water. The preparation method and the proportion are as follows:according to the molar ratio of 20 to (1-20) to 6, the novel ternary compound organic amine medicament is prepared by mixing DETA (diethylenetriamine), TETA (triethylenetetramine) or TEPA (tetraethylenepentamine) and MDEA (N-methyl diethanolamine) or PZ (piperazine) in a solution with a total amine concentration of 0.8 mol/L, according to the preparation conditions, the temperature is 293 K, thepressure is 101.325 Kpa, and the mixing condition is that every two preparation solutions are uniformly mixed at normal temperature and normal pressure. The preparation method of the novel ternary compound organic amine medicament capable of absorbing CO2 with the little water has the advantages that the novel ternary compound organic amine medicament is a flue gas CO2 absorbent with large absorption capacity, good stability of the solution, low energy consumption, high flue gas purification degree, large absorption load, low regeneration energy consumption of the absorbent, fast desorption rate, large desorption load, low oxidation degradation and thermal degradation degree of the solution and less corrosion to equipment.

Description

technical field [0001] The invention relates to a preparation method of a polymer medicament, in particular to a new type of water-less CO2-absorbing 2 A preparation method of a three-component compound organic amine agent. Background technique [0002] In the face of the severe situation of global temperature rise of 2°C, the unfavorable situation that the clean energy that can replace fossil fuels has changed from easy development to difficult development, and the total cost of carbon emission reduction continues to increase; carbon capture, utilization and storage technology (Carbon Capture, Utilization and Storage, or CCUS) is currently the only carbon emission reduction project with commercial prospects, and has good ecological, economic and social benefits. It has made outstanding contributions to reducing carbon emissions in the world. According to research by the International Energy Agency (IEA), carbon capture, utilization and storage technologies can reduce carb...

Problems solved by technology

Although TETA enamine solutions containing more than two primary amino groups are superior to traditional alkanolamines such as MEA, DEA, and MDEA in terms of absorption capacity, absorption rate, absorption load, and resolution, the resolution rate of enamine solutions Compared with alcohol amine solvents, the analysis time is relatively long, which will undoubtedly increase the operating cost in industry
