石蜡年产量27.8万吨的突破

Core Insights - The Daqing Petrochemical Refining Division achieved a record annual production of 278,000 tons of paraffin wax in 2025, marking the highest level in its history, driven by technological advancements, emergency response, and collaborative efforts [1][2] Group 1: Technological Advancements - The refining division focused on three main areas: process optimization, equipment modification, and operational innovation to tackle challenges such as frequent raw material changes and aging equipment [1] - Key process improvements included lowering the feed temperature of critical equipment by 2°C, optimizing the ketone-benzene solvent ratio by 5.8%, and incorporating wax yield into team assessments, resulting in an additional 5,656 tons of paraffin wax [1] - Equipment upgrades included the establishment of a packaging machine testing platform, which reduced downtime by nearly 60 hours and avoided a production loss of 360 tons, saving over 920,000 yuan [1] Group 2: Emergency Response - In May 2025, the division faced a significant drop in viscosity due to raw material issues, leading to a dual approach of "technical adjustment + management optimization," resulting in an additional monthly production of 1,100 tons of semi-refined wax and 700 tons of crude wax, generating over 3.8 million yuan in revenue [2] - An all-weather response system was established, leading to the early elimination of 86 potential hazards and recovering approximately 320 hours of production time [2] - A rapid response to a packaging line failure on December 29, 2024, allowed for a swift restoration of production, ensuring stable operations [2] Group 3: Collaborative Efforts - In response to a surge in paraffin wax inventory, the division implemented a "three-party linkage" mechanism, completing the transportation of 5,700 tons within 18 days to free up storage capacity for continuous production [2] - During the catalyst replacement period from March to April, precise scheduling allowed for the shipment of 34,000 tons of products and the transportation of 11,700 tons, ensuring all six production lines operated at full capacity [2] - The division achieved a total of 251,900 tons of paraffin wax shipped and 35,400 tons transported throughout the year, effectively connecting production to profitability [2]
