摘要

摘要采用碱性氢氧化钠溶液,在小型泡塔反应器中进行了co2捕集实验。实验结果表明,液相中NaOH含量越高,混合气中CO2浓度越高,CO2去除率越高。建立了一个数学模型,描述了低CO2和低OH浓度下CO2气体入口和OH-浓度对CO2吸收量的影响。该模型能准确预测高OH-浓度(高pH)下的CO2吸收量,而较低OH-浓度下的CO2吸收量则不能达到相同的预测精度。关键词:CO2去除naoh吸附等温线h依赖性模型气泡柱披露声明作者未报告潜在利益冲突。

Modeling of a bubble column for CO 2 removal by absorption with NaOH
AbstractCO2 capture experiments were carried out in a small-scale bubble column reactor using alkaline solutions of sodium hydroxide. The results of the experiments show that a higher NaOH content in the liquid phase and elevated CO2 concentrations in the gas mixture led to a higher CO2 removal efficiency. A mathematical model was developed to describe the CO2 absorption as a function of CO2 gas inlet and OH- concentrations at low CO2 and OH- concentrations. The CO2 uptake at high OH- concentrations (high pH) was accurately predicted by the model, whereas the CO2 uptake at lower OH- concentrations could not be predicted with the same accuracy.Keywords: CO2 removalNaOHabsorption isothermpH dependencemodellingbubble column Disclosure statementNo potential conflict of interest was reported by the authors.

期刊介绍: Chemical Engineering Communications provides a forum for the publication of manuscripts reporting on results of both basic and applied research in all areas of chemical engineering. The journal''s audience includes researchers and practitioners in academia, industry, and government. Chemical Engineering Communications publishes full-length research articles dealing with completed research projects on subjects such as experimentation (both techniques and data) and new theoretical models. Critical review papers reporting on the current state of the art in topical areas of chemical engineering are also welcome; submission of these is strongly encouraged.
