Zibo Qixiang Tengda Chemical Co Ltd Website Releases Latest Progress of Maleic Anhydride Plant Upgrade Project
The Qixiang Tengda maleic anhydride unit oxidation line 5.6 upgrade project is a key energy-saving and efficiency-enhancing project with a total investment of over 50 million yuan. Construction began at the end of September 2025, and after a period of intensive work during the winter, the project is now progressing at full speed, making a final push towards its goal of completion by the end of April 2026.This upgrade is far from routine maintenance; it represents a radical transformation and upgrade of the unit's core systems. The project's core breakthrough lies in increasing the original 4.0MPa steam system's pressure to 9.5MPa, enabling the unit to produce its own high-specification steam and completely eliminating reliance on external boilers. Once operational on schedule, the project will generate approximately 40 million yuan in economic benefits annually for the company, while also strongly supporting the company's strategic deployment to shut down one boiler, injecting strong momentum into the energy-saving, consumption-reducing, and green low-carbon transformation of the entire production system.The renovation project involved complex construction processes, significant challenges in coordinating multiple disciplines, and stringent deadlines. The biggest challenge lay in ensuring both the efficient progress of the renovation project and the stable and safe operation of existing production facilities within the plant. This placed extremely high demands on overall project management, on-site safety control, and construction precision.Faced with these challenges, all personnel involved in the Qixiang Tengda project abandoned a wait-and-see approach, focusing on the completion deadlines and meticulously crafting task lists. They infused every task with the spirit of "springtime rewards the diligent," adopting a "sprint from the start, tackle the challenges from the beginning" attitude to accelerate and improve the project's quality.During the preliminary preparation phase, the team rigorously and systematically advanced the bidding process, accurately submitted all materials, meticulously reviewed and verified construction drawings page by page, repeatedly verified the performance parameters of old equipment, and proactively addressed technical obstacles to compatibility between the old and new systems. During the pipeline removal phase, staff meticulously checked pipeline routes and verified media flow, developed comprehensive anti-freezing and anti-condensation plans, and firmly adhered to the bottom line of safe production, clearing obstacles for the smooth progress of the project. From equipment installation to process piping construction, the construction team meticulously refined every procedure and ensured seamless coordination at every stage. Their busy figures moving back and forth on the construction site became the most striking sight during the spring project's arduous journey.During the project's construction, all staff adhered to careful budgeting and efficiency improvement, vigorously promoting the repair and reuse of old materials, resulting in savings of over 10 million yuan in construction costs. All personnel were deeply involved on the project frontline, ensuring the timely arrival of materials, verifying technical parameters, inspecting construction details, and implementing comprehensive safety measures. They maintained close monitoring and meticulous attention to detail, using their professionalism and responsibility to safeguard the project's progress, quality, and safety, demonstrating their commitment to "speeding up the schedule, doing practical work, and creating tangible results."Currently, all participants are united in purpose and working against the clock, creating a vibrant and energetic atmosphere at the construction site. After the construction team arrived on site, welding work on Furnace No. 3 commenced first, and welding of the lower section regenerator box is essentially complete. Core equipment for oxidation lines 5 and 6 arrived on site successively, and welding of the main frame commenced in full swing. On-site management personnel meticulously checked pipeline specifications and equipment indicators against the construction drawings, remaining steadfast at their posts and strictly controlling every step. "Seizing the time, doing practical work, and creating tangible results" has become a consensus among all employees. With the tenacity of "driving nails" and the fighting spirit of "tapping tough nuts," everyone is striving to accelerate the project's construction.Springtime rewards those who are on the move, and now is the time for hard work and progress. Qixiang Tengda is going all out to ensure quality, safety, and progress, determined to win this final battle of the project this spring. A complete victory in this "steam upgrade battle" will inject continuous new momentum into the company's green and high-quality development.
