On January 5, the lowest temperature in Fushun, Liaoning dropped to -18°C. In the aromatic reformation unit area of Plant 3 at Fushun Petrochemical Company, Deputy Director Yu Jian was conducting inspections despite the bitter cold. He checked one by one the parameters such as pressure and temperature at key points of the heat tracing system, and only felt relieved after finding no errors. Just like Yu Jian, the cadres and employees of the Third Oil Plant have integrated the principles of lean management into every aspect of their operations. From millimeter-level control of heating furnaces, to the optimization of the entire process in liquid wax production, and to the precise recovery of carbon-9 components, the path taken by Oil Plant No. 3 to improve quality and efficiency is guided by one clear principle: integrating lean management deeply into every aspect of the production process in order to enhance the company’s ability to create value. Maximize the value of every drop of crude oil. Liquid wax is a high-value-added product produced by the Third Petroleum Plant, and its production volume and yield are key factors in helping the plant optimize its product portfolio and enhance its competitiveness in the market. Focusing on improving production efficiency, Plant 3 for petroleum processing organized technical experts to form a dedicated task force to take targeted actions by addressing various aspects such as raw material optimization, process control, and equipment maintenance. “Stringent control is exercised over the quality of raw materials, key parameters such as reaction temperature and pressure are adjusted precisely, and regular inspections and maintenance of the equipment are carried out to ensure that the installation remains in optimal operating condition at all times. ”A responsible official from the liquid wax production facility said that through a series of precise and effective optimization measures, the production of liquid wax has seen an increase in both volume and efficiency. Currently, the daily production of liquid wax has historically exceeded 860 tons, with stable production and a yield rising above 36%, showing growth for two consecutive months. Furthermore, in the process of optimizing raw material supply and product structure, the plant addressed the bottleneck issue of raw material shortages for the molecular sieve dewaxing unit by purchasing molecular sieve materials from external sources, thereby effectively increasing the production capacity of high-value products such as aviation fuel and liquid wax. Through targeted measures and precise efforts, the added value of this factory’s products continues to increase, thereby expanding its potential for generating profits ； A series of key indicators, such as the comprehensive commodity rate and the comprehensive loss rate, are showing steady improvement. Ensure that every device is in its optimal condition. The safe and stable operation of devices is the foundation for efficient development. Plant 3 for petroleum processing implements precise control over its 5 main production units, establishes a comprehensive control system across the entire process, specifies detailed process parameters and real-time monitoring standards, and adjusts operational strategies dynamically to ensure that the units remain in their optimal operating condition at all times. Heating furnaces are major energy consumers in refineries. To address the issues of high energy consumption and substandard emissions in traditional heating furnaces, Oil Plant No. 3 took advantage of the opportunity provided by the major maintenance of the facilities to upgrade the burners in the molecular sieve workshop’s heating furnaces. After the hardware is upgraded, the software also needs to be improved. Centering on \"precise operation,\" Plant 3 for petroleum processing has refined its entire operational process in line with the key requirements of \"multiple burners, short flames, and uniform flame heights.\" The operators strictly adhere to the specific operating procedures, exercising millimeter-level control over the adjustment of the heating furnace’s “three doors and one panel”: they precisely calibrate the opening degree of the air valves to ensure balanced oxygen supply, finely adjust the flue dampers to control the negative pressure in the furnace chamber, and accurately control the opening degree of the fuel valves to maintain a stable flame pattern. Each operation is verified against standard parameters, and through such meticulous handling, the equipment is brought to its optimal operating condition. The operators exclaimed, “In the past, ‘more or less was good enough,’ but now ‘not even a little bit less is acceptable.’” ”With hardware upgrades combined with improved software, the thermal efficiency of the heating furnace increased significantly to 93%, while environmental parameters such as nitrogen oxides decreased as well, enabling simultaneous progress in energy savings and emission reduction. Turn every resource into a \"valuable resource\" – there are no real wastes, only resources that are in the wrong place. While making every effort to increase the production of high-performance products, Plant 3 for petroleum focuses on maximizing the reuse of resources, ensuring that each resource generates the greatest possible value. Residue oil is a by-product generated by the Third Petroleum Plant during the production of liquid wax, but it contains high-value C9 components. To improve resource utilization efficiency and minimize losses in productivity, the plant deliberately carried out the technical renovation project for the T107 cracking tower. By optimizing the separation process and precisely controlling operational parameters, this project efficiently extracts high-value C9 components from the raffinate oil, which has not been utilized effectively in the past. At the same time, the plant has established a specialized operation and maintenance management system, assigning technical experts to monitor the equipment’s operating conditions throughout the process, and formulating detailed plans for adjusting process parameters to ensure that the recovery efficiency of carbon nine components remains at an optimal level. Once put into use, this project not only resolves the problem of efficiency losses caused by inefficient conversion, but also expands the sources of raw materials for high-value-added products, thereby improving both resource utilization efficiency and economic benefits. In addition, Oil Plant No. 3 adheres to the philosophy of \"low-cost renovation and high-return efficiency,\" makes efforts to manage resources thriftily, and implements various energy-saving and water-saving measures. During summer, excess low-pressure steam is used in the deaerator for water production, successfully solving the problem of steam overpressure venting ； A heat exchanger is added to the power desalinated water recovery system; circulating water is used to cool the condensate water to below 50°C, enabling full recovery of the condensate water in summer and significantly improving resource utilization efficiency. To reduce the water consumption per unit of refined oil, Plant 3 has also taken measures such as optimizing water usage processes, strengthening the detection of leaks in the pipelines, and promoting water-saving technologies, thereby achieving a water consumption level that is lower than the annual target values and realizing significant savings in water use.
