In the ongoing battle against climate change, the energy sector is increasingly turning to carbon capture technologies. A recent study led by Shijian Lu from the Carbon Neutrality Institute at China University of Mining and Technology sheds light on the critical issue of tail gas emissions from CO2 capture absorbers. This research, published in ‘Results in Engineering’, highlights not only the efficiency of organic amine carbon dioxide capture technology but also the environmental risks associated with absorbent and degradation product emissions.
Lu’s team conducted a series of experiments to investigate the factors influencing pollutant emissions from chemical absorption systems. They examined variables such as flue gas condensation nucleation, carbon dioxide concentration, and the temperatures of both the flue gas and the lean liquid. These elements play a significant role in determining the efficiency and environmental impact of carbon capture operations. “Understanding these factors is crucial for optimizing carbon capture systems and minimizing their ecological footprint,” Lu stated.
The study also included a comprehensive analysis of amine escape from a coal-fired power plant with an impressive flue gas treatment capacity of about 1.4 million Nm3/h. The researchers compared various pollutant emission control measures, ultimately identifying a combined approach of “secondary water washing + 7-meter dry bed” as the most effective. This method significantly reduced organic amine absorber loss by 716.5 mg/Nm3, achieving a remarkable 71.65% reduction compared to the traditional “primary water washing” technique.
The implications of these findings are substantial for the energy sector, which is under increasing pressure to adopt cleaner technologies. As governments around the world implement stricter regulations on emissions, the ability to effectively manage and reduce pollutants from carbon capture systems will be essential for compliance and sustainability. “Our research not only addresses the current limitations of carbon capture technology but also paves the way for more effective solutions in the future,” Lu added, emphasizing the commercial relevance of their findings.
As energy companies seek to enhance their carbon capture strategies, this research could serve as a guiding framework for implementing more efficient and environmentally friendly practices. By reducing the environmental impact of CO2 capture processes, the energy sector can move closer to achieving net-zero emissions while maintaining operational efficiency.
