12,000 Ton/Year Hazardous Waste Incineration EPC Project
- February 1, 2024
This hazardous waste incineration unit is an integral part of the Nanjing integrated production base of Celanese, a Fortune 500 American-owned company. The unit is designed to incinerate various types of chemical waste from the factory, including domestic garbage, hazardous solid waste from eight upstream units, sludge, waste liquid, waste gas, and other categories, totaling nine in all. Once operational, the facility will support the factory's commitment to green production and the principle of zero waste leaving the premises.
The unit's centralized hazardous waste disposal capacity is 12,000 tons/year. The unit additionally generates 6.9 tons/hour of 2.5MPa(G) saturated steam, which is integrated into the factory's pipeline network. The waste treatment capacities are summarized in the following table:
The unit occupies an area of 32 meters by 97 meters and includes various process units such as a waste liquid storage tank area, solid waste pretreatment and conveyance, incineration and waste heat recovery, flue gas rapid cooling, dust removal, desulfurization, and denitrification, ensuring that the incinerated flue gas meets emission standards.
This project reached mechanical completion on September 30, 2020, and completed thermal commissioning, including furnace drying, on November 10, 2020. It officially started production and operation in early December 2020.
