Experimental Analysis of Reaction Heat of CO2 Absorption of Phase Change Absorber AEP-DPA at Low Partial Pressure

The reaction heat of CO2 absorption by organic amines is directly related to the regenerative consumption absorbers. Therefore, it necessary study and determine regeneration capture solvent before its industrial validation application. According law thermodynamics, a computer model desorption established verified. AEP-DPA phase transition system was studied under different ratios, temperatures, concentrations pressures. increases with concentration decreases pressure. MEA were compared. optimum conditions as follows: ratio 6:4, temperature 40 °C. reduction rate change more than 35% 31%, respectively.
