Tongxing Technology's International Leading Technology Leads the Green and Low-Carbon Development of the Paper Industry​

Under the tide of the "Dual Carbon" strategy era, the paper industry is undergoing an unprecedented green transformation. As the core equipment of paper enterprises, the flue gas treatment of alkali recovery boilers has become the key to the green transition of the paper industry. With increasingly stringent environmental policies and driven by regulatory requirements, regional pollutant emission caps, and the need for energy conservation and consumption reduction, the demand for alkali recovery boiler flue gas treatment is becoming increasingly urgent.

Due to the complex composition of alkali boiler flue gas, low temperature, high humidity, and high alkali metal content, traditional denitrification technologies struggle to adapt in the alkali boiler environment, exhibiting low efficiency and high energy consumption. The industry urgently requires a highly efficient, stable, and low-energy-consumption denitrification solution truly compatible with the characteristics of alkali recovery boilers. Faced with this industry challenge, Tongxing Technology has successfully developed the "Low-Temperature SCR Denitrification Technology and Equipment for Alkali Recovery Boiler Flue Gas", becoming a key tool for the green transformation of the paper industry. Appraised and certified by expert panels organized by the China Association of Environmental Protection Industry, this technology has reached an international leading level, filled a domestic gap, and was selected for the 2024 National Catalog of Pollution Prevention and Control Technologies.

Compared with traditional denitrification processes for papermaking alkali recovery boilers, Tongxing Technology's Low-Temperature SCR Denitrification Technology for Papermaking Alkali Boilers has very significant advantages: This technology is an external denitrification solution, posing absolutely no impact on the safe operation of the alkali boiler. Due to its high denitrification efficiency, stable operation, process safety, low operating energy consumption, and low maintenance costs, it is expected to become the mainstream process for ultra-low emissions and energy conservation and consumption reduction in alkali recovery boilers within the paper industry.

With advanced technology and rich engineering experience, Tongxing Technology has become a reliable partner for many paper enterprises in their green and low-carbon development. Successful project cases are spread across multiple provinces and cities nationwide. From the land of Qilu to the hinterlands of Southwest China, from world-class pulp and paper giants to specialty paper enterprises, from foreign pulp and paper companies to well-known domestic listed pulp enterprises, the footprint of Tongxing Technology's Low-Temperature SCR Denitrification Technology for Alkali Recovery Boiler Flue Gas covers core papermaking production regions across the country. Solid achievements and stable performance have earned deep trust within the industry.
