Abstract

In this paper, a ternary amine absorbent(2-(2-Aminoethylamino) ethanol, Monoethanolamine, Piperazine, AEEA-MEA-PZ) named DT06 is selected by basic properties and physicochemical properties tests. The main performance is further verified by the 2Nm3 /h testing device and 3000Nm3/h industrial demonstration system. Compare to 30%MEA, the laboratory research results of DT06 show that, the absorption load, regeneration rate and circulation capacity reached 1.39 times, 2.31 times and 1.43 times of MEA, respectively. The viscosity, surface tension, density and other physical-chemical properties are similar to MEA, and the stability is increased by 36.84%. In the case of approximate capture efficiency, the DT06 regeneration energy consumption is only 84.16% of MEA. Industrial demonstration system test shows that, compared with MEA, DT06 reduces the regeneration heat consumption by 34.19%, the electric power consumption for CO2 capture by 13.24%, the degradation rate by 37.8%, and the comprehensive operating cost by 27.37%, which has certain degree of commercial application potential.
