N-methyldiethanolamine 수용액과 이산화탄소간의 반응속도에 미치는 Piperazine의 영향

Abstract

The kinetics of CO₂ with aqueous MDEA(N-methyldiethanolamine) and piperazine added aqueous MDEA solutions were investigated. A wetted-sphere absorption apparatus was used to measure the absorption rate. The apparent reaction rate constant increases with increasing MDEA concentration without piperazine. But the apparent reaction rate constant decreases with increasing MDEA concentration with piperazine. The apparent reaction rate constant strongly increases with increasing piperazine concentration. The highly concentrated MDEA solution needs more piperazine to activate reaction rate. The activation of reaction rate depends on the mole ratio of piperazine and MDEA.
