Measures to ensure the long-term stable operation of ammonia synthesis plants

At work, one must fulfill one’s duties diligently; thorough inspections are essential, along with a rigorous work attitude. Pay attention to subtle changes in real time.

To ensure the long-term stable operation of ammonia synthesis plants, I believe the following measures should be taken: First, the technical department must establish reasonable process parameters and make real-time adjustments based on the actual production conditions. Second, ensure that the focus of equipment operation is on keeping backup equipment in good condition, while also ensuring the timing and quality of equipment maintenance. Third, and most importantly, it is the level of care shown by the operators, which ensures that all management systems are implemented properly. In addition, managers must possess a strong sense of responsibility. In short, the human factor is very important

Scientific management, reasonable compensation, and incentive systems. Big goals, small steps. Don’t seek quick success; have reasonable goal planning and safeguard measures!

I. Sense of responsibility: Whether they are managers or operational staff, everyone needs to enhance their sense of responsibility, treating their work as their own responsibility and carrying it out diligently and proactively, rather than viewing it as a task assigned by superiors that needs to be completed perfunctorily. They should work carefully, conduct thorough inspections, and ensure proper management. II. The decision-making level should have scientific management, as well as reasonable compensation and incentive systems. Enable all employees to feel a sense of achievement, honor, and belonging while working. III. The company’s equipment must meet quality standards, with proper maintenance and repair. Another point is that while operating over a long period of time, it is also necessary to ensure safety and handle high loads in order to be profitable.

Establish a scientific and reasonable equipment maintenance system； The responsibilities in process management are clearly defined, with reasonable planning and thorough execution ； Appropriate incentive mechanisms ensure a high level of responsibility among operators.

First, it is necessary to strictly enforce the process parameters in order to prevent process operation accidents； Second, it is necessary to strengthen routine inspections in order to promptly identify and address potential safety hazards in production facilities, thereby preventing problems before they occur. Third, carry out proper maintenance of the equipment to extend its service life.

The two key elements for the operation of a device are materials and people; ensuring long-term stable operation requires focusing on these two aspects. From a material perspective: reasonable process design, qualified equipment, advanced testing methods, and sophisticated technology, etc ； From a human perspective: ideal process control, timely inspections, high professional competence and sense of responsibility, as well as a high availability rate of backup equipment.

I think the key to high-pressure equipment and pipelines lies in whether employees conduct thorough inspections during their working hours Some vibrations and leaks should be addressable at the initial stage. If it’s discovered too late. Major accidents could occur.

Proper staff training: From top to bottom, those who fail the training cannot take up their posts. Effective employee motivation: Absolute fairness may not be possible, but relative fairness can be achieved. The work environment is good, allowing it to fully motivate people. When each position is conscientious and responsible, problems can often be identified and resolved in a timely manner. Raw material procurement must be properly controlled: avoid a trial-and-error approach; not everything should be tried out. If there’s a problem in any step, the entire process will be affected. Information can be gathered extensively, thorough investigations can be conducted, and careful evaluations can be performed to identify qualified suppliers. Control over the procurement of equipment and spare parts is ensured: same as above. Also, it needs to be reviewed by someone who knows the subject. Proper management of processes and equipment is essential; practical new technologies should be adopted, such as leak sealing under pressure. Continuous improvement must be pursued: thorough analysis is needed to constantly optimize various production factors. In short, it seems that everything revolves around the quality management system. But then again, it makes sense – things that have been refined over decades surely can’t be that bad.

(1) There is a team of highly qualified production and maintenance personnel. Being familiar with and capable of managing ammonia synthesis production, as well as cultivating a team of highly skilled production and maintenance personnel, are the decisive factors for ensuring successful ammonia synthesis production. Tasks required to ensure the long-term operation of the facility: (1) Strengthen the technical training of employees. To improve everyone’s knowledge of the basics of ammonia synthesis, technical personnel often conduct lectures to explain the fundamental aspects of the synthesis process, and by taking into account the basic characteristics of ammonia synthesis, they effectively integrate theory with practice. Through such highly targeted explanations, everyone’s understanding of the equipment improved, and at the same time their technical knowledge and skills were enhanced as well. ⑵Broaden employees’ knowledge structure. It is necessary to broaden employees’ knowledge base; specialized technicians in machinery, electricity, and instrumentation are hired to explain the knowledge related to machinery, electrical systems, and instruments in the context of ammonia synthesis. This enables employees to integrate various types of knowledge into their actual work, use this knowledge to analyze and assess problems, thereby achieving a mutually beneficial outcome. ⑶Strengthen safety and quality management to achieve the integration of the three standards. From the workshop supervisor to safety and quality managers, and to every employee, a single idea is consistently instilled: \"To value safety means to cherish life.\"” ； “Ensuring product quality is to create economic benefits” ； “Paying attention to environmental protection means bringing benefits to future generations.” In the management, development, and progress of synthesis workshops, this philosophy serves as a guiding principle for enhancing the moral and professional ethics of employees. At the same time, implement \"three standards integrated\" management and establish comprehensive supporting documents for such management. The accumulation of these small efforts has turned the synthesis workshop into a team with strong technical skills capable of achieving success, as well as a team that can operate and manage the ammonia synthesis plant effectively, ensuring its long-term operation. (II) Ensure cooperation and coordination among related units such as machinery, instrumentation, and electrical equipment, as well as their managers. Large-scale ammonia synthesis production is a relatively complex systems engineering task in modern chemical manufacturing; the safe and stable operation of the entire plant requires coordination and cooperation among mechanical systems, instrumentation, electrical equipment, as well as related units and managers. As is well known, during the testing phase at our company, the majority of the shutdowns of the installation are caused by problems in the design, manufacturing, and installation of equipment, instruments, and electrical components, as well as by the installation’s control and safety systems (PLC logic interlocks). Especially, the most cases are caused by instrument malfunctions. Therefore, while ensuring that its internal staff acquire knowledge in machinery, instrumentation, and electrical systems through learning and training, the workshop also strengthens management and maintenance by focusing on the following aspects. For example: The workshop requires employees to identify the operating temperature of valve solenoid valves during inspections” ； “Valve positioner, feedback mechanism, position identification” ； “Identification of pump operation conditions” ； “Leak detection at pipeline equipment connection points” ； “Strengthen inspections and ensure quality in aspects such as “parameter assessment at on-site monitoring points”. These have all become the fundamental guarantees and key factors for the workshop to ensure the long-term operation of the equipment. Furthermore, considering that the ammonia synthesis plant has been in operation for over a decade and that some of its instruments, equipment, and electrical systems are gradually reaching the end of their useful life, increasing the risk of accidents, the \"three-standard integrated\" management system implemented requires that those instruments, equipment (such as transmitters and sensing elements), mechanical devices, and electrical equipment that need to be replaced be replaced promptly. It is also required that \"inspections be carried out with both quality and quantity ensured, and any issues found should be reported promptly to enable timely resolution.\" Of course, the new equipment replaced must indeed have quality assurance; otherwise, even if it is replaced, it serves no practical purpose and may even have a negative effect, leading to the shutdown of the device. The workshop has strengthened management in this area and coordinated well with the relevant departments. In addition, the workshop has also introduced requirements such as: process workers should uphold the spirit that \"details determine success or failure\" during their routine inspections at work ； Clarify “for whom I work”” ； Management regulations that promote the concept of \"working with dedication\" are established to ensure the proper fulfillment of routine inspection duties, to carry out one’s job with high professional ethics, to identify issues in the equipment in a timely manner, and to address them promptly. (III) Strengthen team management to promote the safe and long-term operation of the plant. Teams (including those responsible for process, mechanical, electrical, and instrumentation operations and maintenance) are the smallest units responsible for the operation and maintenance of the plant, and they are directly involved in actual production. Therefore, whether the various management systems within these teams are sound and well-established is a fundamental guarantee for efficient production. For example, the systems for various positions within the team, the routine inspection system, the shift handover system, the reward and punishment system, the training system for technical knowledge and skills, the equipment hygiene management system, the production maintenance and operation execution system, the system for strengthening training of new employees, and the safety education system, among others. Only when all such systems are improved can such a collective possess combat effectiveness ； Only in this way can the company’s and workshop’s systems for production management be fully implemented, thereby ensuring the proper operation and maintenance of production equipment and achieving its long-term stable and safe operation.

I fully agree with those who spoke above; in summary, it is necessary to adhere to the \"four standards\": standard operations, standard inspections, standard maintenance, and standard repairs”
