Abstract

Comprehensive technical analysis is vital for the large-scale industrialization of a certain potential amine solvent. This paper proposes a technical evaluation method to assess amine-based CO₂ capture processes thoroughly. The method's validity was also verified by using the DEEA-HMDA as an example, compared with various conventional amine solutions in terms of the above three technical properties. Based on the technical properties analysis, a new rapid screening assessment method for amines based on technical indicators proposed. In addition, eight conventional amine solvents selected to calculate the technical indicators (including packed column design, solvent consumption, and regeneration energy consumption) reflected by these three technical properties. The packed column volume (44.5 m³), solvent consumption (2.28 kg/tCO₂), and regeneration energy consumption (18.64 KW·h/tCO₂) of using DEEA-HMDA as a CO₂ absorbent were lower than the most commonly used MEA. In conclusion, the blended amine DEEA-HMDA is a potential carbon capture alternative solvent.
