When you have worked for more than 15 years, you can independently complete the design work of multiple projects, and have a deep understanding and understanding of the design process of the automatic control profession. Petroleum (according to the characteristics of petroleum refining, petrochemical industry, oil and gas processing, etc.), chemical industry (traditional chemical industry, coal chemical industry, fine chemical industry, pharmaceutical intermediates, etc.). The adaptability and rationality of the instrument will be fully considered from the contents of the detection instrument, analysis instrument, control system and other contents learned from the book and the content observed in the field investigation. In particular, the technological development and upgrading of the control system should be faster, and new products, new technologies and new processes should be constantly captured. This requires us to combine solid theoretical knowledge with complex practical operations, so as to achieve the purpose of integration. This is a good way to grow, from the actual observation of the site to absorb the content and then into the design institute or engineering company to do automation professional engineering design should be updated and optimized, optimized, improved and improved. Leading a team to continuously enrich the experience, accumulate experience, is handy and comfortable in the work. It includes complex growth experiences and remarkable achievements such as communication and coordination with various majors, condition review and coordination. People who race against themselves (live)., Li Zongsheng.
One. Main knowledge points
1.Detection instrument basic principles (temperature, pressure, flow, liquid level, control valves, shut-off valves, etc.).
2.Basic principles of analytical instruments (chromatography analyzer, total sulfur analyzer, calorific value analyzer, trace water analyzer, trace oxygen analyzer, hydrocarbon analyzer, etc.).
3.Safety instrumentation fundamentals (gas detectors, flame detectors, etc.).
4.Basic principles of special instrumentation (eddy current sensors, speed sensors, load cells, etc.).
5.Control system fundamentals (DCS, SIS, GDS, PLC, CCS, AMS, SCADA, ETC).
6.Automatic control principle (simple control loop, may pay more attention to how to tune the PID?) Ratio control loop, selective control loop, three-impulse control loop, cascade control loop, split control loop, etc. have a deeper understanding and cognition, to the extent of mastery.
I have a very comprehensive understanding of all the above contents of the professional design of I&C, and can easily deal with different industries, different formula uses, and difficulty levels of the project.
Two. Petrochemical Automatic Control Design Manual (Fourth Edition) (edited by Huang Buyu).
After all this experience, you probably have this book on your desk, covering the full range of applications in the design industry. The design process and engineering design of a chemical project are described in detail. For example, the optimal design of the control room (explosion-resistant, non-explosion-resistant, single-layer, two-layer, cable entry manhole, sealing module, etc.), instrument selection, instrument explosion-proof, protection, anti-corrosion, power supply, gas supply, heat tracing, heat insulation, instrument installation, cable, bridge, pipe valve and other material selection. There is also the understanding and application of new processes, new technologies, new products, etc. This manual is suitable for petroleum and chemical engineering design technicians.
Three. Learning and comprehension of standards and norms
According to the industry field where the design institute or engineering company is located, find the corresponding standards and specifications (GB, SY, SH, HG, AQ, XF, rules and regulations, administrative decrees, etc.) and read and study in depth. For example, GB 50183 for oil and gas, GB 50160 for petrochemical, GB 51428 for coal chemical industry, GB 51283 for fine chemicals, perhaps due to the relationship between work, it may be converted from oil and gas to petrochemical industry or coal chemical industry, etc., due to the continuous transformation of roles to adapt to new specifications has also become a compulsory course, and it is also their own ability to become stronger. I learned more knowledge and enriched the width and length of knowledge points. From the engineering design of cross-industry fields, we can have a deep understanding of the design characteristics of each industry, the focus of I&C design, and the essentials that should be paid special attention to in engineering.
Four. A walkthrough of an engineering design project
Due to the different platforms of the design institute or the engineering company, from the contact to the project implementation period, from the actual point of view, through a large investment project to deeply experience the process of each design link, so as to achieve the principle of "reviewing the old and learning the new, keep improving", and integrate theory and practice to achieve a perfect combination.
Five. Summary
Through the above suggestions, you have fully met the requirements of a senior designer, and continue to enrich your experience and improve your self-worth through the design process of several projects.
