Research progresses on organic amine solution absorption method for biogas purification process
Organic amine solution absorption method,a mature carbon capture technology,has many advantages such as fast CO2 absorption rate,high selectivity and excellent regeneration effect,which has critical research significance and application value in the field of biogas upgrading,but has high regeneration energy consumption,volatility,degradability and some environmental risk issues which thus greatly restrict its commercial value.In this paper,the research progresses on organic amine absorption method in the field of biogas purification is systematically reviewed in terms of the process flow,reaction mechanism,manipulable variables,existing issues and its application status,and corresponding research ideas and suggestions are proposed to promote the application of organic amine absorption method in the field of biogas upgrading.The results show that the CO2 absorption efficiency can be significantly improved by appropriately elevating the concentration of amines,and the mixed amine solution can be conducive to the improvement of the lower economy in the biogas upgrading process of monoamine solution.In addition,compared to the traditional dry absorption method,the energy consumption of the amine solution absorption method in the CO2 capture process can be reduced by more than 30％,implying that the amine solution absorption method requires more energy input compared to the dry absorption method.
