Benchmark Project | Wuzhou Special Paper Alkali Recovery Boiler and Lime Kiln Flue Gas Desulfurization and Denitrification Integrated Treatment Project

In response to the challenges of stringent flue gas emission standards and complex system matching for ultra-large-scale alkali recovery boilers and lime kilns, TONEXUS Technology has customized a coordinated dry and wet desulfurization process for Wuzhou Special Paper, combined with a low-temperature SCR denitrification system, to achieve stable and deep treatment of both types of high-temperature and high-load units.

The project can flexibly switch between dry and wet desulfurization modes according to changes in SO₂ concentration. Meanwhile, the denitrification system has been designed with additional capacity to ensure continuous and stable operation under full-load conditions.

The project is scheduled to be put into operation in January 2027. After commissioning, NOx emissions are expected to remain stable at ≤50 mg/Nm³, while SO₂ will be controlled within 10 mg/Nm³. With economical and reliable system operation, the project will provide a mature engineering model for coordinated emission reduction across multiple furnace types in large-scale paper manufacturing bases.
