摘要

研究了微反应器内

-甲基二乙醇胺溶液解吸过程的流动和气提强化行为。观测到解吸过程中气-液两相流型主要有泡状流、弹状流、环状流和细环流。高温时，流型交替演化将导致气泡速度波动。气提促进强化CO

解吸过程的结果表明，低溶液流量时，少量惰性气体就可显著提高CO

解吸速率；大惰性气体流量将缩短停留时间，经计算解吸强化效率，确定了解吸过程的最佳气提流量。

Abstract

The flow pattern and stripping enhancement of CO

desorption from

-methyldiethanolamine solution were investigated in microreactor. It is observed that the gas-liquid two-phase flow patterns in the desorption process mainly include bubble flow

slug flow

annular flow and fine circulation. However

the periodic change of flow patterns resulted in the fluctuation of bubble velocity at high temperature. According to the results of stripping enhancement on the CO

desorption

it showed that CO

desorption rate was significantly enhanced at low solution rate by adding small amount of inert gas

while excessive gas will lead to a reduction in the solution residence time. The optimal inert gas flow rate was determined by calculating the stripping enhancement per unit gas flow rate.
