P10 超音波照射と塩化カルシウムを組み合わせたモノエタノールアミン溶液か らの二酸化炭素の低温脱離

We investigated the effect of the ultrasound irradiation with CaCl₂ addition on desorption amount of CO₂ from MEA solution at low temperature. The desorption amount of CO₂ as gas is regulated by pH. To overcome the regulation of pH, CaCl₂ was added just before the ultrasound irradiation. As the results, CO₂(g) desorption ratio was improved. CaCl₂ was reacted with HCO₃^－ and pH of the solution decreased.
