Coke Dry Quenching Unit

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.

Coking wastewater treatment

In response to the complex composition, high pollutant concentrations, recalcitrance, and high salinity of coking wastewater, a comprehensive treatment process combining biochemical treatment, membrane separation, and evaporation‑crystallization has been implemented to achieve true zero liquid discharge—enabling water reuse while recovering and valorizing sodium chloride and sodium sulfate from the salt fraction. The biochemical treatment employs an O‑A/O‑A/O process; membrane separation utilizes a UF‑RO1‑RO2 configuration for reclaimed water and a multi‑stage NF process for salt fractionation; and evaporation‑crystallization adopts triple‑effect evaporation coupled with cryogenic cooling and re‑crystallization for salt recovery. The biochemical system primarily removes the majority of COD, ammonia nitrogen, cyanide, and other pollutants, ensuring that effluent quality fully meets regulatory standards. The membrane separation stage focuses on water recovery, producing concentrated brine suitable for subsequent evaporation‑crystallization. Finally, the evaporation‑crystallization unit enables the resourceful utilization of sodium chloride and sodium sulfate while solidifying residual salts, thereby achieving true zero liquid discharge for coking wastewater. This integrated technology offers significant advantages, including stable operation, strong resistance to shock loads, high water‑recovery efficiency, consistent salt‑product quality, and genuine zero liquid discharge.

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.
