For the standard procedures in chemical process operations, should one memorize them first or observe how experienced workers carry them out first?

First, get familiar with it in writing, then learn how to do it from a master

I agree with the opinion from the second floor; I will follow the process below. 1. Based on the operating procedures, examine the process flow diagram and check the functional parameters of the equipment to gain a preliminary understanding. 2. Familiarize yourself with the site and figure out the route of each pipeline. Use a digital camera to take pictures of the details. 3. Refer to the flowchart and photo details to draw a detailed axonometric diagram of the entire process pipeline and equipment (indicating the models and numbers of pipes, valves, and equipment, as well as medium parameters, etc.). After drawing it, go to the site to verify it repeatedly to ensure it matches the actual situation there. PS: The goal is to learn and consolidate; things that are processed mentally are not easy to forget. This is consistent with real-world situations, and it might be useful in the future as well. Well-managed legitimate companies don’t need to do it themselves; the information should be available in their records. 4. Take the axonometric diagram to the work post, ask about each step and detail of the operations there, identify any differences from one’s own understanding, and record them to analyze the reasons and determine whether they are reasonable. Find out about the difficulties and bottlenecks in production. 5. The remaining tasks include summarizing, analyzing, tracking, exploring, and pursuing professional learning*, etc.

Learning from a master mainly involves improving practical skills through experience; it is important to summarize one’s experiences. If you are not familiar with the production processes or control parameters, learning on the job will be very slow. It is recommended to first become familiar with the process flow, control parameters, instrument tag numbers, and equipment performance of this unit, and then go to the site to further enhance your understanding of the process by combining it with the pipeline layout and equipment operation.

Only after you understand the entire device can you figure out what the technician is doing Why do it this way? I’m a beginner too; we’ve been drawing PID charts for 3 months, and I just started working on site, taking shifts with the experienced workers.

What the moderators say is all correct; the written material represents the essence of what the masters have learned over the years, and it makes sense. We must first study this material before learning the practical experience from the masters, and by comparing it with what’s written, this is often the stage when one gains the most. You often find, oh! So that’s what the book meant... In fact, as you gain more hands-on experience, you can even develop your own set of approaches – that’s knowing not only what to do but also why”

First, read the written operating procedures, and then, if you get the chance, work alongside experienced workers on-site. Generally, the written instructions and actual practice are not exactly the same, and at such times you should think critically and ask more questions – this way your skill level can improve rapidly.

I agree with the explanation on the second floor. First, learn the *theoretical knowledge and become familiar with the process flow. First, learn the operating procedures*, and only then operate under the supervision of a mentor.

Combine theory with practice, and repeatedly familiarize oneself and draw conclusions

First, learn the written material, and then learn from experienced masters. After all, the master has a great deal of practical experience

I agree with what was said above; you can also take the flowchart to the site when you have time free to get familiar with the process.
