Zhonghan Petrochemical completed the intelligent upgrade of its solid packaging lines. On February 7, the project for collecting data from the weighing devices on the 10 packaging lines in Zhonghan Petrochemical’s flat warehouse was successfully completed, marking the end of the one-and-a-half-month-long process of upgrading these packaging lines. All solid packaging production lines are now under digital management, which has enhanced the ability to control product measurements and improved the efficiency of production management. It is reported that Zhonghan Petrochemical has a total of 16 solid packaging production lines; previously, in September 2024, they completed the intelligent upgrade of the weighing systems for 6 of the packaging lines in their automated warehouse. Led by the Petrochemical Production Management Department of China and South Korea, a project team was formed for this initiative; by utilizing 5G wireless transmission technology, the intelligent upgrade of the weighing systems on 10 packaging lines in the flat warehouse was completed in just 45 days, which is a significant reduction compared to the usual time required. The new system achieves a 100% accuracy rate in data collection, automatically gathering 150,000 pieces of data per day. Efficient data collection and analysis have significantly enhanced a company’s ability to control quality in the packaging process. Technological innovation played a key role in this upgrade. To address the issue of older devices lacking network ports, the project team developed its own 5G data acquisition terminals, utilizing wireless networking technology to enable device connectivity. This approach saved 500,000 yuan in costs associated with device upgrades, thereby reducing expenses effectively. With the commissioning of new equipment, Sino-Korea Petrochemical has achieved full coverage in three areas regarding measurement and monitoring in its automated warehouses and conventional warehouses: full coverage of production lines and key control points, as well as full traceability throughout the entire process. This system can display in real time the weight deviation of each packaging line, automatically summarize trends and set alarms, ensuring accurate product measurement and preventing loss of efficiency. Compared to manual sampling, testing efficiency and data reliability are significantly improved. Intelligent transformation has also given rise to valuable data assets. By comprehensively managing the data from the rechecking scales, Sino-Korean Petrochemical can keep the error margin per package within 10 grams. According to calculations, with a production volume of 1 million tons of solid products, reducing the error in packaging bag weight by 1 gram can lead to a reduction of 40 tons in product loss per year, resulting in significant cost savings. These data assets provide a scientific basis for the subsequent optimization of the packaging line, laying the foundation for more accurate evaluation. The success of this intelligent transformation has not only enhanced Sino-Korea Petrochemical’s capabilities in product measurement and control but also provided valuable insights for the company’s future digital upgrades. With the deeper application of technologies such as 5G and big data, Sino-Korean Petrochemical will continue to advance the process of intelligent manufacturing, providing technological momentum for high-quality development.
