CO2 sequestration technology, also known as carbon capture and storage (CCS), is a crucial approach in mitigating climate change by capturing carbon dioxide emissions from industrial processes and power generation before they are released into the atmosphere, and then securely storing them underground in geological formations or utilizing them in other applications. This technology encompasses a range of methods, including pre-combustion capture, post-combustion capture, and oxy-fuel combustion, each designed to isolate CO2 from flue gases or process streams. Once captured, the CO2 is compressed and transported via pipelines to suitable storage sites, such as depleted oil and gas fields or deep saline aquifers, where it is injected and monitored to ensure long-term containment. The development and deployment of CO2 sequestration are essential for achieving global carbon neutrality goals, as it allows for the continued use of fossil fuels while drastically reducing their environmental impact, bridging the gap until renewable energy sources can fully meet global energy demands.

CCS carbon capture and storage relies on high-performance absorption solvents to effectively separate carbon dioxide from mixed gas streams, and our independently developed TX-1 absorption solvent is designed for this core demand of CCS projects. This solvent has outstanding CO2 absorption selectivity and large absorption capacity, it can maintain stable working performance even under complex flue gas components, with lower regeneration energy consumption than conventional absorption solvents, which helps reduce the overall operational cost of the whole carbon capture system.

NOx reduction system, a crucial component in modern industrial emissions control, employs advanced chemical and physical processes to convert nitrogen oxides (NOx) into harmless nitrogen (N2) and water vapor (H2O). This system typically integrates technologies such as selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR), which utilize specific reagents like ammonia or urea to facilitate the reduction reactions. Its design ensures high efficiency in removing NOx pollutants from exhaust streams, thereby significantly mitigating environmental impacts like acid rain and smog formation. The operation of the NOx reduction system is characterized by robust performance under varying load conditions, contributing to cleaner air and compliance with stringent emission regulations.
