- 摘要:
- 随着含CO2天然气的大量开发，当前天然气脱硫与脱碳两种工艺开始分别沿不同思路进行技术开发，逐步形成了两大类以甲基二乙醇胺（MDEA）为基础的配方型溶剂：即混合胺和活化MDEA。这两类溶剂虽然都使用了活化剂以改进MDEA溶剂的脱碳性能，但两者在反应机理、工艺流程、操作条件与适用范围等方面皆有很大区别。总体而言，混合胺溶剂主要应用于改善MDEA溶剂对H2S和CO2的净化度；而活化MDEA溶剂主要应用于基本上不含H2S而CO2含量甚高的原料气，并采用多级降压闪蒸和半贫液循环流程，以达到大量节能的目的，对于此类溶剂应从反应机理着手进行技术开发，才能收到事半功倍的成效。
With more and more development of natural gas field containing CO2， technology development in natural gas desulfurization and decarburization process is being carried out respectively according to different ideas currently and such two categories of synthetic gas desulfurizers have been formed gradually as mixed amine and activated MDEA， which are based on activated Methyl Di Ethanol Amine（MDEA）. Although activating agent has been added into two categories of gas desulfurizers in order to improve decarburization performance of MDEA， there is a great deal of difference between the gas desulfurizers in reaction mechanism， technological process， operation conditions and application range， etc. and technology development shall be started from reaction mechanism in order to get twofold results with half the effort.
