摘要
对MEA、DEA、TEA、DETA、TETA几种胺类脱碳吸收剂及其与MDEA混合胺液的解吸性能进行了实验对比分析,考察了不同种类单一胺液及混合胺液解吸率等指标的变化规律。结果发现,DETA、TETA两种烯胺及其与MDEA的混合胺液解吸效果相对较差,而提高其吸收的饱和程度,有助于改善解吸性能。
The desorption properties of five kinds of amines MEA, DEA, TEA, DETA, TETA and their mixed amines with MDEA in the process of CO2 removal from natural gas were analyzed by the comparative experiments. The change regulation of desorption rate of different types of single amine and mixed amines was investigated. The results showed that the desorption properties of two kinds of enamines DETA, TETA and their mixed amines with MDEA were relatively poor. While the desorption properties of the above amines could be improved by increasing the absorption saturation.
