胺活化热碳酸钠吸收液解吸CO_2动力学研究

A Study on the Desorption Kinetics of CO_2 from Hot Activated Na_2CO_3 Stripping Liquid

对二氧化碳在热碳酸钠吸收液和胺活化热碳酸钠吸收液中的解吸进行了理论分析，并在搅拌式反应器中测定了这两类溶液在工业条件范围内的温度、转化度、胺含量对ＣＯ＿２解吸速率的影响。由实验数据回归整理得到计算解吸速率系数的关联式，为工业生产和工程设计提供参考．

The desorptions of CO_2 from hot Na_2CO_3 stripping liquid and amine activated liquid areanalysed theoretically,and the influences of temperature,conversion degree and amine-concentrationin the stripping liquids on the desorption rate of CO_2 are measured with a stirred cell under industrialconditions.Aequation for calculating desorption rate coefficient is obtained,which can be used as areference for industrial production and engineering designs。
