Abstract
Using plastic packing instead of stainless steel packing can significantly reduce the investment cost of carbon capture absorber. In order to improve the mass transfer efficiency of packing, it is necessary to evaluate its mass transfer performance in different solvents systems. Based on CO2(air) – NaOH solution system, different solvents properties are simulated. The surface tension of the solution is changed by adding non-ionic surfactant and the viscosity is changed by adding polyethylene glycol. The mass transfer performance and characteristics of ST 250Y hydrophilic modified plastic packing and stainless steel packing are tested and compared in a packed column with an inner diameter of 300mm and a packing height of 2000mm. The experimental results show that the mass transfer properties of modified plastic packing and stainless steel packing have similar characteristics under various conditions, and modified plastic packing has more advantages in solvents with low surface tension. Based on the experiment, the prediction correlation of the two kinds of packing is fitted, which can accurately predict the effective mass transfer area of the packing under different gas velocity, liquid surface tension and viscosity. The predicted results are in good agreement with the experimental values.
