MEA二元复合胺溶液对CO2吸收的研究进展
wf（2023）
Abstract
全球温室效应日益加剧,CO2减排刻不容缓,乙醇胺(MEA)法作为目前工业上应用最广泛、技术最成熟的烟气CO2吸收方法,具有吸收速率快、成本低的优点,但是其能耗大、吸收量小和易损耗的缺点也很明显.针对目前常见的MEA二元复合胺溶液展开对比分析,阐述了MEA二元复合胺溶液的研究进展,总结了MEA吸收溶液中加入其他醇胺溶液形成二元复合胺溶液后在吸收速率、吸收量和再生能耗等方面对CO2吸收效果不同程度的改善情况.基于总结与分析,提出了吸收剂开发需要从吸收机理、溶解度、吸收负荷、解吸速率、解吸操作条件以及再生能耗等方面进行综合比选的思路,可为新型吸收剂的开发提供一定的指导.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
