In order to further promote the high-quality development of the Shandong papermaking industry through digital and intelligent empowerment, summarize the industry’s operational achievements, discuss and exchange typical experience in such areas as digital and intelligent empowerment, energy conservation and carbon reduction, quality improvement and efficiency enhancement, guide the industry toward greener and more efficient development, accelerate the cultivation of new quality productive forces, and organize specialized technical exchanges and site visits, it has been decided, after research, to hold the Shandong Province Conference on Digital and Intelligent Empowerment for High-Quality Development of the Papermaking Industry and the 2026 Papermaking Industry Annual Conference in Guangrao County, Dongying City, from May 8 to 9. The following is a promotional introduction to the organizers, co-organizers, supporting units, and other participating entities of the conference.
TONEXUS Technology Co., Ltd. is a company listed on the Main Board of the Shenzhen Stock Exchange (003027). Upholding the corporate philosophy of “Shaping the Future of Net-Zero Industry Together,” the company is committed to becoming a global strategic partner for pollution reduction, carbon reduction, and industrial net-zero. Established in 2006, the company focuses on flue gas treatment, CCUS, and the R&D and manufacturing of new energy materials and equipment. Its services cover multiple industries, including steel, power, coking, building materials, chemicals, non-ferrous smelting, waste incineration, papermaking, and new energy.
TONEXUS Technology adheres to driving industrial upgrading through technological innovation. Relying on its three major R&D centers in Hefei, Beijing, and Ma’anshan, the company has built an efficient and open innovation platform. It has undertaken a total of 12 national scientific research projects and research topics, and, as the Chinese lead entity, has undertaken an intergovernmental China–South Korea energy technology cooperation project. The company possesses core qualifications such as Class A Design Qualification for Air Pollution Control Engineering and First-Class Professional Contracting Qualification for Environmental Protection Engineering, forming a comprehensive capability system integrating R&D, manufacturing, engineering implementation, and project services. At the same time, the company’s catalyst laboratory has passed CNAS National Accreditation, and the company owns more than 200 authorized patents, more than 20 invention patents, 3 software copyrights, 5 first-of-its-kind products/equipment sets, and 13 high-tech products, continuously strengthening its capabilities in technological innovation and the commercialization of scientific achievements.
In terms of core technologies, TONEXUS Technology has developed a solution system represented by low-temperature SCR DeNOx catalysts, EPC flue gas treatment, and CCUS technologies. TONEXUS’s low-temperature SCR DeNOx catalyst can operate within a temperature range of 150–400°C and has been applied in 800+ projects across industries such as coking, steel, papermaking, and chemicals. In the papermaking field in particular, the company has specifically developed special low-temperature SCR catalysts for recovery boilers and catalyst protection technologies. Its “Low-Temperature SCR DeNOx Technology and Equipment for Recovery Boiler Flue Gas” has been appraised as reaching an international leading level and was included in the Ministry of Ecology and Environment’s 2024 National Directory of Pollution Prevention and Control Technologies, enabling NOx concentrations to be controlled at ≤40 mg/Nm³. Meanwhile, the company continues to advance key CCUS technologies and has developed coordinated capabilities in absorbents, processes, and equipment, providing systematic support for pollution and carbon reduction in the industrial sector.
In the field of flue gas treatment for the papermaking industry, backed by 20 years of industrial flue gas treatment engineering experience, TONEXUS Technology has continuously made breakthroughs in key technologies for low-temperature SCR DeNOx and coordinated treatment, focusing on the complex operating conditions of key units such as recovery boilers and lime kilns, and has developed systematic solutions covering different scales and operating conditions. In response to the common characteristics of papermaking flue gas—such as high alkalinity, high dust content, low-temperature operation, and the difficulty of coordinated treatment of NOx, SO₂, and white plume—TONEXUS Technology helps customers achieve stable compliance and cost reduction with efficiency improvement through customized process design, dedicated catalyst development, and integrated engineering implementation.
At present, the company has built a number of benchmark projects in the papermaking industry. Its clients include APRIL, Sichuan Yongfeng Paper, Wuzhou Special Paper, Taison, Lee & Man Pulp, and Jinlong Pulp & Paper, among others. Project types cover low-temperature SCR DeNOx for recovery boilers, coordinated desulfurization and denitrification treatment, and integrated white plume elimination projects. After commissioning, many projects have achieved stable NOx control within 40–60 mg/Nm³, while some projects have also realized deep treatment of SO₂ and particulate matter, as well as effective white plume elimination, fully demonstrating TONEXUS Technology’s technical adaptability and system stability under complex operating conditions.
From medium-sized recovery boilers to ultra-large-scale system engineering, and from single denitrification to multi-pollutant coordinated treatment, TONEXUS Technology is providing solid support for the green and low-carbon transformation of the papermaking industry with its mature and reliable technologies, extensive and solid engineering experience, and continuous innovation capabilities.
This is the first one.
