Instrument engineers are important engineering and technical personnel for the implementation of intelligent and digital sulfuric acid equipment. In order to make the sulfuric acid device after the completion of intelligent and digital upgrade, and maintain safe, stable, long, full, excellent operation, the instrument engineer needs to master a series of professional skills, in the current development of the sulfuric acid industry, the instrument engineer needs to have higher requirements for the skills, the following are the key skills that should be possessed.

1. Principle and structure

It is necessary to have a deep understanding of the basic principles, structural characteristics and working principles of various types of instruments. It includes understanding the design theory and working principle of virtual instrument [1], the structure and characteristics of control instrument and regulating valve. At the same time, it is also necessary to have the instrument data sheet preparation, instrument selection, installation and debugging methods to ensure the accurate measurement of the instrument in the sulfuric acid device.

2. Maintenance and Calibration

The maintenance and calibration methods of various instruments should be mastered to ensure the accuracy and reliability of the measurement results of the instrument. The sulfuric acid device must understand the maintenance methods of high concentration sulfuric acid analysis, flow rate, level, pressure, temperature, actuator and regulating valve, and be able to prepare maintenance plans, formulate instrument calibration standards and operating procedures, and regularly calibrate the device instrument to ensure measurement accuracy and the reliability of the regulating valve operation.

3. Automation

It is necessary to be familiar with the composition, principle, computer and electrical equipment knowledge of automatic control system, mainly including PLC, DCS, APC, digital sulfuric acid and other control systems programming, configuration and debugging. It is necessary to design and implement automatic control schemes according to the actual needs of sulfuric acid plants to improve energy efficiency, safety and environmental protection control.

4. Data Analysis and Interpretation

With the intellectualization and digitalization of the sulfuric acid plant, the threshold information of the operation data of the device is reduced by the management personnel, and it is difficult to find the hidden trouble in time. Therefore, instrument engineers should have the ability to collect, organize and analyze the instrument data, conduct in-depth interpretation of the data, timely find the abnormal situation in the production process, and propose effective improvement measures. At the same time, it is also necessary to use data analysis technology to provide data support for the optimization of production process.

5. Fault diagnosis and maintenance

After the automatic production of sulfuric acid plant, the reliability of the instrument is higher. Instrument engineers should be able to quickly identify instrument failures and have appropriate preventive measures or maintenance measures. The instrument fault judgment method is standardized and programmed. Safety operation procedures should be followed in the maintenance process to ensure maintenance quality and personnel safety.

6. Information Technology

In today's industrial Internet era, sulfuric acid devices use big information technology: such as data analysis, network communication, bus, 5G and so on. Therefore, instrument engineers need to master certain information technology knowledge, such as computer operation, network communication, AI technology, etc., in order to better apply information technology means to improve work efficiency. At the same time, it is also necessary to pay attention to the development of information technology and constantly update their knowledge and skills.

7. Process basis

Basic knowledge of sulfuric acid chemical engineering, including chemical reaction principle, thermodynamics, fluid mechanics, heat and mass transfer knowledge. This knowledge helps instrument engineers to understand chemical changes and physical processes in sulfuric acid production process, and provides theoretical basis for control optimization and problem solving.

8. Equipment and operating procedures

Familiar with the main equipment of sulfuric acid plant, such as sulfur furnace, converter, absorption tower, pump, valve, fan, etc. Understand the structure, performance, working principle and maintenance methods of the equipment, and master the operating procedures and precautions. It is also necessary to pay attention to the upgrading and upgrading of equipment to improve the operating efficiency and safety of equipment.

9. Safety production and environmental protection

Should always put production safety and environmental protection in the first place, need to understand the relevant production safety regulations and environmental protection requirements, to pay close attention to various safety risks and environmental hazards, timely detection and treatment of possible problems, to ensure the safety and stability of the production process and environmental protection standards.

10. Regulations and standards

Familiar with laws, regulations and standards related to sulfuric acid production, including environmental law, safety law, etc. Ensure compliance and safety of the sulfuric acid production process. At the same time, it is also necessary to pay attention to the update and change of relevant laws and regulations and standards, and timely adjust and optimize the instrument.

11. Communication and Cooperation

Instrument engineers need to work closely with multiple professions and departments, so having good communication skills and teamwork is essential. It is necessary to communicate information clearly and accurately, listen to the opinions and suggestions of others, and solve problems together.

In summary, as mentioned in Article 11 above, sulphuric acid plant instrumentation engineers need to have a variety of professional skills and qualities to cope with the complex production environment and challenges of the new ecology of sulphuric acid plant. Through continuous learning and practice, we can improve our professional level and contribute to the stable operation of sulfuric acid plants and the improvement of production efficiency.
