Two Carbon Capture Technologies from Tongxing Technology Featured in GCCSI’s Annual Report

Recently, the Global CCS Institute (GCCSI) officially released State of the Art: CCS Technologies 2026. GCCSI is an international professional think tank dedicated to accelerating the global deployment of carbon capture and storage (CCS) technologies. It has long been engaged in industry research, technical exchange, and policy advocacy, and has extensive influence in the global CCS sector. Tongxing Technology’s TX-1 Series Carbon Capture Absorbents and TXIO Wet CO₂ Capture Process were successfully featured in the report, showcasing the company’s technological achievements in the development of low-energy carbon capture absorbents, process optimization, and industrial applications to a global audience.

State of the Art: CCS Technologies 2026 focuses on cutting-edge technologies that have already been deployed or are progressing toward commercialization. It brings together solutions from more than 90 CCS technology providers worldwide, covering key parts of the industry chain, including CO₂ capture, capture-enabling technologies, transportation, and storage. The publication provides an international platform for technical exchange among technology providers, project developers, and industry decision-makers.

TX-1 Series Carbon Capture Absorbents

Low-Energy and Stable Capture under Complex Flue Gas Conditions

Designed for industrial flue gas conditions characterized by low CO₂ partial pressure, high oxygen content, and complex impurities, Tongxing Technology’s TX-1 Series Carbon Capture Absorbents adopt a function-oriented design that combines low energy consumption, resistance to degradation, and stable operation. According to the report, the regeneration energy consumption can be as low as 2.1 GJ/tCO₂, approximately 35%–40% lower than that of conventional MEA absorbents. Its oxidation resistance is approximately 21 times that of MEA, while its service life can be extended to two to three times that of conventional absorbents. The series currently includes low-energy, balanced, and economical product types, which can be adapted to applications in the steel, cement, power generation, waste incineration, and marine exhaust sectors. The products have already been applied in multiple industrial projects and have achieved Technology Readiness Level 9 (TRL 9).

TXIO Wet CO₂ Capture Process

System Optimization for Lower Energy Consumption, Reduced Emissions, and Lower Costs

To address the high steam consumption, difficulties in system water-balance control, and large volumes of pretreatment wastewater commonly associated with conventional wet carbon capture systems, the TXIO Wet CO₂ Capture Process incorporates designs such as functional zoning of pretreatment, regeneration-gas washing, two-stage spraying, and latent heat recovery from the top of the regeneration tower. These designs enable effective system water-balance control and efficient heat utilization. According to the report, the process can reduce pretreatment wastewater discharge by approximately 30%–90% and alkali consumption by approximately 30%–60%. When used together with dedicated absorbents, steam consumption can be reduced by approximately 35%–40%. The process has already been applied in projects across the steel and building materials industries. In the 150,000-tonne-per-year converter gas CO₂ capture project at Rizhao Steel, annual operating costs are expected to be reduced by approximately USD 600,000 compared with conventional solutions. The technology has also achieved TRL 9.

Supporting Industrial Low-Carbon Transformation through Technological Innovation

The inclusion of these two technologies in GCCSI’s annual Technology Compendium provides a concentrated demonstration of Tongxing Technology’s capabilities in carbon capture absorbent development, process design, and engineering applications. It also creates a new platform for the company’s technological achievements to reach international markets. Going forward, Tongxing Technology will continue to address the carbon-reduction needs of the steel, building materials, energy, and marine industries by advancing the development and application of low-energy absorbents, carbon capture processes, and system equipment. The company will continuously improve the economic efficiency, adaptability, and operational reliability of its solutions to support customers in their green and low-carbon transformation.
