Flue gas desulfurization and denitrification
The flue gas desulfurization and denitrification system is a flue gas purification technology widely applied in the chemical industry to control the formation of nitrogen oxides and sulfur oxides. The system employs a self-developed low-temperature, sulfur‑resistant denitrification catalyst, enabling a sequential process of denitrification followed by desulfurization. While achieving ultra‑low emissions of nitrogen oxides, sulfur dioxide, and particulate matter, it also efficiently recovers waste heat from coke oven flue gas, maximizes steam production, and resolves the issue of excessive ammonia slip. In the desulfurization stage, a CFB fluidized‑bed process is utilized, with hydrated lime as the desulfurizing agent, effectively reducing operating costs. The system features a simple process flow, minimal water consumption, and eliminates the need for flue gas cooling or reheating. Equipment exhibits virtually no corrosion, scaling, or wastewater discharge; it occupies a small footprint, saving space, requires low capital investment, and incurs modest operating expenses. With its high adaptability, the system is suitable for diverse operating conditions and can be customized to optimize performance based on specific customer requirements, helping coking enterprises achieve ultra‑low emissions and green production.

The dry quenching system employs inert-gas circulation cooling to cool red coke in a sealed environment, while recovering the high‑temperature sensible heat of the coke for power generation or heat supply. The system’s core equipment includes the dry quenching furnace, primary dust removal, a waste‑heat boiler, secondary dust removal, and circulating fans, offering significant advantages such as high thermal efficiency, improved coke quality, and reduced pollutant emissions. Compared with conventional wet quenching, it effectively lowers emissions of particulate matter, phenols, cyanides, and other pollutants, while also recovering substantial amounts of thermal energy.
