Analysing the Effect of CO2 Concentration in Flue Gas on CO2 capture Characteristics of Hollow Fibre Gas Membrane System

Popis výsledku v původním jazyce

Membrane technology has been established as an efficient technology for capturing CO2 from multicomponent flue gas mixtures. The primary focus of this study is to examine the potential influence of CO2 concentrations in the feed flue gas stream on the CO2 capture characteristics of hollow fibre membrane module systems, whose fibre materials are made of polyetherimide-polyimide. The experiments were conducted on pure gases (CO2, N2) and multicomponent gas mixtures (N₂ + CO₂ + O₂), containing fixed amount of O2 (4.3 %vol) and variable %vol of CO₂ and N2 respectively, at a fixed volumetric flow rate of 130 Nlh-1, at a temperature of 30 °C and a constant pressure difference of 8.57 bar. The objective was to determine and predict how flux, permeance, CO2/N2 selectivity/separation factor, stage cut through the membrane, retention coefficient as well recovery to the permeate stream vary with different CO2 feed compositions. The results demonstrated that CO₂ flux, permeance and percentage recovery kept increasing as the proportion of CO₂ in the feed gas stream increases. CO₂ permeance 6.29 GPU and recovery 96 % peaked at a feed concentration of 55 %vol CO₂, with a minimum retention coefficient of 4 %. In contrast, the highest CO₂ separation factor 3.3 occurred at a feed concentration of 25 %vol CO₂.
