At the turn of the year, more good news came from Fujian Nanhua New Materials’ aniline additive project. On December 29, the water purification unit for the auxiliary agents production area of this project, constructed by Shaanxi Huajian, was successfully commissioned for the first time, marking the official entry of the project’s auxiliary facilities into operation and laying a solid foundation for the future commissioning of the main production units. Shaanxi Huajian undertook the construction work for this project, including the civil engineering, steel structure, equipment, storage tanks, process pipelines, electrical and instrumentation systems, as well as anti-corrosion and insulation measures for three main units: a 44,000-ton/year TMQ plant, a 30,000-ton/year RT PES plant, and a 42,000-ton/year 6PPD/IPPD plant. It also handled the construction of 12 auxiliary facilities, such as the central control room, central laboratory, Substation 2, and Substation 3. The water purification unit that has been successfully commissioned is the main source of water for the entire plant. With a design capacity of 600 cubic meters per hour, it can store enough water for 8 hours of production, ensuring adequate water supply for the plant’s production equipment, auxiliary facilities, and tank areas. It will provide essential water support for the completion and operation of the project. Since the start of the fourth quarter, the project team has focused on efficient task execution in order to meet the annual goals, advancing the improvement of project quality and efficiency through a combination of \"meticulous management\" and \"collaborative efforts\". In terms of management, a \"list-based control + milestone-driven advancement\" approach is adopted, with annual goals broken down into detailed lists, monthly tasks further divided into weekly tasks; simultaneously, construction plans, staffing plans, and daily work plans for key milestones are developed ； During project implementation, a responsibility system is established where team leaders are assigned to specific tasks, with progress reported daily, thereby significantly improving the efficiency of coordinating and resolving issues on site ； In terms of quality and safety management, a grid-based management system is utilized, along with dedicated supervisors, to establish a solid defense mechanism for construction safety. Through the joint efforts of the project team and the constructors, the construction of the 15 individual facilities progressed efficiently: on October 27, the fire pump station, the production water purification system, and the foam station were completed to high standards in terms of mechanical installation ； On November 30, the No. 3 circulating water station was put into operation, and the system’s pipeline network was flushed ； On December 18, Substation No. 3 was officially put into operation ； On December 20, the individual test run of the air compressor in the air compression station was successful on the first attempt.
