In this study, a 3-inch diameter ceramic hollow fiber membrane contactor unit module with an improved flow path was successfully developed for CO₂ capture. The effect of CO₂ loading in the absorbent, water and oxygen in the flue gas was evaluated in order to evaluate the performance of the ceramic hollow fiber membrane module. No performance degradation was found for water vapor and oxygen in the flue gas. On the other hand, absorption performance decreased with the amount of CO₂ loaded in the absorbent. The 2-stage module was able to absorb more than 90% of CO₂ in 0.5 Nm³/h flue gas with 0.17 mol CO₂/mol MEA loaded absorbent. At this time, the gas and liquid pressure drops were 0.012 and 0.010 bar, respectively. This is a small value compared to the pressure drop of the conventional packed absorption column process. In addition, the integrated membrane absorber/stripping column process was operated for more than 60 h and the CO₂ removal efficiency was maintained at about 84%. There was no decrease in performance or pore swelling of the membrane. Ceramic hollow fiber membrane contactor is a promising process that can replace conventional absorption process or polymeric membrane contactor.

在这项研究中，成功​​开发了具有改进流路的3英寸直径陶瓷中空纤维膜接触器单元模块，用于CO ₂捕集。为了评估陶瓷中空纤维膜组件的性能，评估了吸收剂中的CO ₂负载量，烟道气中的水和氧气的影响。没有发现烟气中的水蒸气和氧气的性能下降。另一方面，吸收性能随吸收剂中负载的CO ₂量而降低。2级模块可以吸收90％以上的CO ₂在0.5纳米³ /小时0.17摩尔CO的烟道气₂/ mol装有MEA的吸收剂。此时，气体和液体的压降分别为0.012和0.010 bar。与常规填充吸收塔工艺的压降相比，这是一个很小的值。此外，集成的膜吸收器/汽提塔工艺运行了60小时以上，CO ₂去除效率保持在约84％。膜的性能或孔膨胀没有降低。陶瓷中空纤维膜接触器是一种有前途的方法，可以代替传统的吸收法或聚合物膜接触器。
