Exchange on process management – I am in charge of production at a chemical plant. I find that equipment management is relatively easy to handle, as equipment failures are obvious and can be easily identified and resolved. However, problems related to processes are not as easy to detect, and some of these problems can even pose threats to safe production and system stability. How can process management be improved? Process management mainly focuses on process parameters. Process discipline management, plant energy conservation management, plant compliance management, quality management, plant operation without shutdowns, interlock records, and process review systems. Equipment management is not merely about leaks; many changes in process parameters are caused by the equipment, and these aspects are closely interconnected. Good managers are generalists, regardless of their specialty. Managing effectively depends mainly on how you utilize your employees. If you have capable people to help you out, management becomes much easier. It’s not advisable to carry everything alone, as it is exhausting and not conducive to the company’s development. Key aspects include the implementation of process parameters, the inspections carried out by operators, the recording of process data, the compilation of process reports, the status of operations on-site (such as any leaks or other issues), and energy efficiency in the production process. 1. I believe that various production records are crucial; they serve as essential evidence of how the production processes are carried out. By properly managing these original records, it becomes possible to have a clear understanding of how the process parameters are being implemented. 2. Various process specifications, operating procedures and other process-related documents, as well as production process records, must all be prepared carefully and meticulously. Equipment is also difficult to manage; it’s just that you didn’t make the cut. Every aspect has its own challenges. I have been in charge of production, processes, and equipment on various occasions. Be meticulous and diligent, and persevere. In terms of process management, it is first necessary to maintain proper process records, keep track of developments, make accurate notes, conduct evaluations, analyze situations promptly, and make adjustments in a timely manner. By putting people first and drawing on diverse ideas, we can do our work well. Do one’s job diligently right now, and don’t be fickle. That’s my experience from work. When research, process technology, and processing equipment are integrated together, that’s success – what more could one hope for? Let’s discuss the specific responsibilities of a workshop process technician. Besides ensuring the proper operation of the equipment, what else are there? Technicians, please share your experiences so that we can exchange ideas and lay a better foundation for carrying out our work. The duties of a workshop process technician are quite complex; in addition to routine tasks such as recording daily production data, checking operational conditions, preparing monthly, quarterly, and annual technical reports, submitting reports on production status, analyzing operational fluctuations, and overseeing compliance with process regulations, they also need to optimize the operation of the equipment and propose practical suggestions based on its actual performance. In short, the effective operation of a production facility is directly related to the technical skills and work attitude of the process technicians. Work standards for process engineers in our factory – Main responsibilities: 1. Planning and Organization 1.1 Participate in the development of the annual work plan for production processes and process safety management in this workshop. 1.2 Participate in formulating the production process improvement and energy-saving plans for this workshop, and organize their implementation. 1.3 Participate in formulating the work plan for technical training of employees in this workshop. 2. Organization 2.1 Based on the characteristics of the production facilities in this workshop, determine the central control parameters for each processing step as well as the quality standards for the products. 2.2 Assist the workshop supervisor in formulating detailed process training plans and implementing them. 3. Leadership 3.1 Organizing the control and management of production process elements within this workshop under the quality management system ； Energy management in the ISO14000 environmental management system. 3.2 Provide guidance, supervision, inspection, evaluation, and feedback on the operational skills of workshop employees. 4. Control 4.1 Participate in formulating the regulations for various aspects of process safety management in this workshop and supervise their implementation. 4.2 Calibrate and analyze operating parameters daily to ensure safe and efficient production. 4.3 Go deep into the production site to understand the situation regarding production and process technology management, identify problems promptly, and report them to the workshop supervisor. 4.4 Assist the workshop supervisor in preparing technical training cards for various positions in the workshop, as well as conducting training and assessments. 4.5 Participate in handling accidents that occur during production operations, provide relevant data, materials, and drawings in a timely manner, and offer suggestions for dealing with such accidents. 4.6 Understand the operating status of the production equipment in this workshop; when there are abnormalities in the manufacturing process or product quality, participate with various departments of the company in analyzing the causes and formulating measures to address them. 4.7 Keep abreast of domestic and international advancements in production processes, and propose suggestions and plans for introducing new processes and technologies based on the actual conditions of production in the workshop. 4.8 Conduct statistics and analysis on the production costs in the workshop, identify problems in a timely manner, propose corrective measures, and report to the workshop supervisor. 4.9 Complete all tasks assigned by the workshop supervisor in a timely manner. Production management is actually a comprehensive issue. As for process management, it involves formulating practical process systems and operating procedures, and then improving these procedures and systems based on the actual operational conditions ； Secondly, it is necessary to analyze and summarize the process records; only after relevant discussions can process parameters and the existing problems within the process be identified, thereby enabling improvements to any unreasonable aspects of the process.
