From April 17 to 18, the 2025 (Fourth) Carbon Dioxide Capture, Utilization and Storage Technology Exchange Conference, hosted by China Coal Chemical Industry Network, was held in Yulin, Shaanxi. As a leading enterprise in carbon capture technology, TONEXUS Technology showcased its independently developed TX-1 carbon capture absorbent and low-partial pressure capture process at the conference. The company also delivered a keynote presentation at the technical forum, where its innovative solutions attracted widespread attention from participating experts, scholars, and industry representatives.
The technical presentation addressed two core industry challenges—absorbents and process technology—by proposing exclusive solutions.
TX-1 Stable-Efficiency Absorbent
Antioxidant capacity improved by 20-300 times compared to competitors, enabling long-term cyclic use.
Acid gas net load exceeds 35 L/L, reaching internationally advanced levels.
Resistant to corrosive media such as iron ions and chloride ions.
Customizable absorbent supply tailored to user-specific conditions.
Low-Partial Pressure Capture Process
Optimized pretreatment tower specifically designed for high-moisture, low-concentration CO₂ sources in power plants, steel mills, cement plants, and other industries.
Steam consumption as low as 1.1 tons per ton of CO₂.
Efficient and ingenious utilization of regeneration gas without employing "electricity-for-heat exchange" methods.
On-site samples of the absorbent attracted numerous attendees. After 30 days of continuous operation, the absorbent exhibited only slight discoloration. The company's proprietary two-phase absorbent system was publicly displayed for the first time. Featuring an ultra-simple composition, it requires no phase separation conditions and achieves rapid automatic phase separation within one minute. The acid gas desorption rate of the heavy phase exceeds 90% (at 98.5°C), with an acid gas net load greater than 48 L/L—an industry-first achievement.
TONEXUS Technology has deeply developed its stable-efficiency absorbent system and process technology, now possessing full EPC capabilities for wet carbon capture recovery and purification projects. The company offers exclusive solutions to common market challenges such as high absorbent energy consumption, rapid degradation, and corrosion. Moving forward, TONEXUS Technology will continue to actively support China's "Dual Carbon" strategy, promote the in-depth application of carbon capture technology, and enrich its product and business systems. With a comprehensive industry chain business layout, the company aims to better serve its customers.
