Recently, good news came from Wuhu Petrochemical Company in the northwest part of China: the ultra-low emission renovation project for the boilers at this plant, carried out by Xi’an Aerospace Yuanpower Engineering Co., Ltd., has successfully passed environmental inspections, with all parameters meeting ultra-low emission standards. The successful completion of this project marks the successful finish of Wushi Petrochemical’s key environmental protection projects, and it also signifies the successful operation of the company’s second ultra-low emission demonstration project built in Xinjiang. This project utilizes the company’s independently developed integrated technology for ultra-low emission control, which combines ammonia-based desulfurization with dust removal. A new desulfurization system is installed, while the existing one is upgraded; once completed, these two systems operate as backups for each other, thereby enhancing the reliability of the desulfurization equipment, reducing the pressure associated with controlling total pollutant emissions, and improving the air quality in the surrounding area. The newly built system is capable of handling 500,000 Nm3/h of flue gas. At the inlet of the desulfurization tower, the sulfur dioxide concentration is ≤3000 mg/Nm3, while the dust concentration is ≤30 mg/Nm3. After treatment by this system, real-time monitoring data shows that the concentrations of dust and sulfur dioxide can be maintained at nearly zero levels of 2 mg/Nm3 and 0.5 mg/Nm3, respectively. Due to the unique geographical and climatic conditions in Xinjiang, the region is in a frozen state for nearly half a year each year, making it impossible to carry out construction work. The project team overcame the pressures of tight deadlines, high difficulties, tough working conditions, and strict requirements, fully demonstrating the spirit of the Source Power team members – their willingness to take on challenging tasks and persevere. Construction of this project began on May 26, 2018. The system started operating in a combined water and transport mode on September 6, 2019; completion of the construction was achieved on October 8. The newly built desulfurization system came online on October 11, and the project passed third-party inspection on December 16. To this day, the system maintains continuous and stable operation, with its reliable service meeting all specified standards.
