MES is booming in domestic petrochemical industry

For a long time, the focus of China's manufacturing informatization construction has generally been on the ERP management system and process control system (such as DCS). The production management technology and real-time information system facing the workshop floor has been left blank, resulting in corporate planning and Information "faults" occur between process control layers. The emergence of MES has just made up for this gap and has become a "bridge" for the integration of enterprise information integration, communication planning and process control. At present, the application of the MES system by well-known foreign companies is a common phenomenon, but the domestic application is still in its infancy.
According to Zheng Mingdeng, secretary-general of the Informationization Construction Working Committee of the China Chemical Industry Enterprise Management Association, MES is a real-time information system for the production and implementation level of process industries (ie, workshop level) and is the core of an integrated enterprise automation system. The application of MES in the domestic chemical industry has just started. The pilot work for the first phase of the China Petroleum MES project includes four refining companies: Jinxi Petrochemical, Daqing Petrochemical, Dalian Petrochemical, and Jinzhou Petrochemical. Honeywell's software products are mainly used. At present, the MES of these four companies have been successfully put into operation. Sinopec has launched MES pilot companies Maoming Petrochemical, Anqing Petrochemical, Jingmen Petrochemical, Jinan Petrochemical and Luoyang Petrochemical. In addition, MES has also been applied in more than 10 companies such as Yuntianhua, Shandong Haihua, Zhejiang Juhua, Shanxi Tianji, and Sichuan Meifeng. From the perspective of the application of the above-mentioned enterprises, MES has optimized the product structure, increased the yield of high value-added products, reduced energy consumption and processing losses, improved product quality, improved the level of refined management of enterprises, and achieved information technology. The effective combination of manufacturing technology.
In the global market, MES mainstream suppliers include Siemens, Honeywell, GE and other large automation manufacturers, as well as UGS, Apriso and other professional software manufacturers; domestic can provide related products and services of the Chinese Academy of Sciences Institute of software, petrochemical Yingke, Zhejiang University Zhongguan, Shilin Company and Beijing Heli Time. In terms of applications, MES is mainly used in some large manufacturing companies in the process industry. A well-designed MES system can integrate management functions such as production scheduling, product tracking, quality control, equipment failure analysis, and network reporting on a unified platform. Through the use of a unified database and network connectivity, it can simultaneously be a production department and a quality inspection department. , process departments, logistics departments, etc. to provide workshop management information services, make it easier for companies to establish a rapid response, refinement, a unified information environment, improve enterprise production efficiency, improve product quality and service quality, reduce consumption and cost, ensure On-time delivery plays an important role.
To successfully implement MES, an enterprise must first improve the management foundation and select the "fitting" MES software system according to its own situation. Without strict management constraint mechanisms, the timely maintenance of MES system information is difficult to guarantee; without advanced management models, the information that MES organizes cannot be effectively used, and thus it cannot produce benefits. The management foundation work closely related to MES includes workshop environment, division of responsibilities, and personnel protection. Having perfected the management link, we can consider implementing the MES project. A typical MES implementation process mainly includes several stages of pre-work, implementation preparation, simulation and trial operation, switching operation and new system operation.
According to the technical personnel of Zheda Zhonghuan Control, taking refinery companies as an example, the implementation of MES can achieve material balance across the entire plant, through the establishment of enterprise core database, can support the application of ERP systems and meet its requirements of "day balance and ten days settlement"; Management tools include consistent and shared data sources, tank collection and payment management, automatic device data correction, real-time oil movement tracking and oil balance tools, material balance tools, utility data balance tools, integrated production Scheduling, dynamic plan statistics, etc. MES data cover a wide range of data frequency, with real-time data acquisition.
In the interview process, the reporter learned that some user companies have some reflections on MES applications. Since the MES system has just begun to be used in China, there are still many aspects that need to be improved. MES is oriented to the actual production, and the status of companies varies, resulting in general MES products are often difficult to fully meet the needs of enterprises, the implementation process needs to be customized according to user needs to develop the work. Although foreign MES products have some advantages in terms of algorithms, they are not in line with China's national conditions in terms of business processes and user suitability.
According to Li Xiaohua, deputy chief engineer of Sichuan Meifeng Deyang Branch, Meifeng has been on the line for MES for one and a half years, although some functional modules still have only one platform and have not yet been put into use, but have basically met the production needs and improved. Management level reduces security risks. However, the system also exposed some problems in the process of operation, and the overall sense of the product's depth and scalability is not enough, especially the analysis of the report function is not yet ideal.
Looking at the current application situation of the entire industry, the problems existing in the implementation of MES in enterprises mainly focus on PB (Material Balance) module, PS (Production Planning and Scheduling) module, OM (Operation Management) module, and LIMS (Laboratory Information Management System). On the module.
Looking to the future, relevant experts pointed out that MES has great potential for application in the domestic petrochemical industry. MES should gradually evolve from a current general-purpose system to a standardized system, and then gradually develop into a specialized system, and develop specialization for different fields and industries. MES system. Based on this further development, MES will eventually be intelligent, and be able to "think" like a corporate planner.
It is understood that MES is an information technology that has rapidly developed in the world in the past 10 years for the petrochemical, steel, power, pharmaceutical, papermaking and other process industries. Petrochemical MES is a complete software system for petrochemical enterprises MES construction, including two parts of the public support environment and business support modules. Its main function modules include production planning and scheduling, production and operation management, tracking logistics, material balance, public project information management, yield calculation, real-time database, laboratory information management system, production statistics, production and operation information platform.
