Side Dishes Studying PID 5

Before entering the study, you must first know what the PID you want to see is mainly about, what your chemical plant is going to produce, and then start to know the principle, simply put, the chemical equation, and then know what the raw materials are, and what kind of processing the raw materials are, and then know the reaction principle, under what circumstances, what intermediate products are generated, and how the intermediate products are decomposed or other ways to get our final products, and the final products are distilled, and the pure substances we want are obtained. At the same time, there must be a lot of by-products in the reaction stage, and whether there is anything we want that is completely purified in the distillation process, there must be a waste waste gas**, and then there are three wastes to be treated, or there are ** substances to return to make raw materials, these are the content of the whole PID to be reacted to you, so it is very important to know these to master the process. The above is the first step for you to do, the next is to look at the process, the pipeline will indicate all the equipment, all the instruments, some sewage and exhaust pipelines, and some special requirements, these are a piece of cake for you to understand, because before you look at the process, you already know what to do at each stage. After reading the process, and then looking at the process description, learn more about all the PID.

If conditions permit, you will be clearer when you go around the construction site, and at this point, you can almost start to see how the people in the DCS control room control, and the next job is for you to start controlling the DCS. It's easy to say, it's hard to do, and I'm okay to talk nonsense here, but I think it's a little right, and I must praise it, and if it's not right, I have to point it out! I want to improve!

I need your support and encouragement, and I also need your timely criticism!

Just use the normal inner join query!

First, then wait and see how he reacts, and then you ask me again. It's better to send me the ** after waiting.

If it's hibernate, I know how to do it.
