The Shandong Paper Industry Digital-Intelligent Empowerment and High-Quality Development Conference and the Member Representative Assembly of Shandong Paper Industry Association were successfully held in Guangrao, Dongying. With the theme of “Digital-Intelligent Empowerment for High-Quality Development,” the conference brought together representatives from industry associations, research institutes, paper companies, and technology and equipment providers to conduct in-depth exchanges on topics such as digital-intelligent transformation, energy conservation and carbon reduction, quality improvement, and efficiency enhancement in the paper industry, jointly exploring new paths for the high-quality development of the sector.
As an important participant in the fields of industrial flue gas treatment, pollution reduction, and carbon reduction, TONEXUS Technology was invited to attend the conference and delivered a technical presentation focusing on the flue gas treatment and low-carbon transition needs of recovery boilers in the paper industry. At the conference, Wu Wei, Deputy General Manager of TONEXUS Technology, delivered a keynote speech titled “Denitrification and Carbon Reduction Technologies and Applications for Flue Gas from Paper Recovery Boilers.” Combining environmental policy requirements for the paper industry, the flue gas characteristics of recovery boilers, and engineering application cases, the presentation systematically introduced TONEXUS Technology’s innovative achievements and practical experience in low-temperature SCR denitrification, collaborative treatment of recovery boiler flue gas, and carbon reduction technologies.
At present, as environmental standards continue to become stricter, paper companies are facing higher requirements in terms of stable compliance with nitrogen oxide emission limits, long-term reliable system operation, and the coordinated advancement of pollution and carbon reduction. Flue gas from recovery boilers generally features low temperature, high humidity, special dust composition, and strong corrosiveness, posing higher challenges to the adaptability of denitrification processes, catalyst performance, and system stability.
In response to the difficulties in flue gas treatment for recovery boilers in the paper industry, TONEXUS Technology has developed a low-temperature SCR denitrification system solution suitable for complex operating conditions. Through multiple technical designs, including multi-chamber independent denitrification technology, online thermal regeneration technology, catalyst protection technology, material upgrades for key components, and high-efficiency ammonia/flue gas mixing devices, the company effectively improves system operation stability. These technologies meet engineering requirements such as online maintenance without shutdown, in-situ catalyst regeneration, anti-blockage, and corrosion resistance, providing reliable support for paper companies to achieve long-term stable emission compliance.
In terms of catalysts, TONEXUS Technology has developed a dedicated low-temperature denitrification catalyst for recovery boilers, targeting the characteristics of low temperature, high humidity, and alkaline dust in recovery boiler flue gas. The catalyst features excellent low-temperature activity, sulfur poisoning resistance, hydrophobic performance, and alkali metal poisoning resistance. It can better adapt to the complex flue gas environment of the paper industry and help companies achieve efficient denitrification and energy-saving operation under lower temperature conditions.
At present, TONEXUS Technology’s low-temperature SCR denitrification technology has been applied in multiple paper industry projects, serving companies including Asia Symbol, Sun Paper, Jiangsu Bohui Paper, Lee & Man Paper, Wuzhou Special Paper, and Taison Bamboo Resources. The project types cover low-temperature SCR denitrification for recovery boilers, flue gas denitrification for lime kilns, and collaborative desulfurization and denitrification treatment. Among them, the implementation of multiple low-temperature SCR denitrification projects for Asia Symbol recovery boilers, as well as large-scale recovery boiler treatment projects, has provided valuable engineering references for the deep flue gas treatment of large-scale recovery boilers in the paper industry.
In addition to the treatment of flue gas pollutants, TONEXUS Technology continues to promote the research and development of carbon capture, energy-saving processes, and system equipment technologies in response to the low-carbon transformation needs of the paper industry. The company has built up technical expertise in chemical absorption carbon capture, TX-1 absorbent, high-efficiency heat exchange equipment, and energy-saving process optimization, providing more technical pathways for paper companies to carry out carbon reduction, carbon resource utilization, and green low-carbon upgrading in the future.
The paper industry is an important field for promoting the green transformation of industry. Looking ahead, TONEXUS Technology will continue to focus on technological innovation in flue gas treatment, CCUS, and low-carbon technologies. Centering on the coordinated pollution and carbon reduction needs of the paper industry, the company will continue to provide efficient, stable, and energy-saving systematic solutions, helping paper companies improve their environmental governance capabilities and promoting the high-quality development of the industry toward greener, smarter, and lower-carbon operations.
