How to Become a Good Engineering Designer Posted by a Designer: During this time, I saw on the forum that some netizens were confused about engineering design. I would like to share my views based on my experience and understanding of the profession. Process design actually covers a lot of content and is the leader of the entire project design. If you are a project manager, after getting a project, you must know the material balance, heat balance, time balance, etc. Especially the heat balance (including the calculation of the heat of reaction), if you don’t know how to calculate the heat of reaction, it would be very scary. ； Secondly, you need to understand the control scheme, whether it is ratio control, cascade control or feedforward control, etc. ； Furthermore, you must understand the equipment, equipment selection, materials, processing characteristics, dynamic equipment, and static equipment. ； You also need to understand civil engineering. A project manager who doesn’t understand civil engineering is incompetent. ； You also need to know something about strong electricity. For heat calculation, it is difficult to find information on the heat of many reactions. So most of it depends on estimation, so how to estimate? This requires you to have solid basic knowledge, including knowledge of chemical engineering thermodynamics and physical chemistry. You must at least know Beson's estimation method. Calculation of heat can be said to be very important, as it involves the design of reboilers, condensers and reactors. There are also calculations of phase equilibrium. Some data are needed in distillation calculations, especially the calculation of relative volatility. Process calculation: Process calculation is indispensable in process design. This is when you really work hard. You think that the development you do in the laboratory is technology, and engineering is not technology, it is just drawing pictures. I despise people who think this way. Engineering is technology, and it is a very critical technology. Today's process calculations tend to use software such as Aspen, ProⅡ, etc. I don’t know these softwares. I mainly use Excel and calculators that can integrate, and I am now learning Matlab. Process calculations require reasonable use of some estimates and experience. These experience values ​​come from engineering practice and cannot be learned from books. For chemical equipment, you need to understand dynamic equipment, static equipment, etc. Because the process is realized through equipment. Choosing reasonable equipment is very important for the process. The choice of mechanical seal for dynamic equipment is very important, and when to choose the form of mechanical seal is very important. I think equipment experts should agree with this statement. Civil construction knowledge: Civil engineering is the prerequisite for all projects. As a project manager, you should complete the conceptual design of the civil engineering of the project. Because civil engineering is directly related to your equipment layout. Civil engineering is also very important to the piping profession, especially for some fixed-length pipes. Sometimes, the procurement plan for fixed-length pipes has to be changed because a small beam was not considered. The upper reinforcement and lower reinforcement in civil construction are something that project managers need to know when trying C30. In chemical civil engineering, embedded iron is very important and very useful for installation. In one project, I put nearly 1,000 pieces of embedded iron, but later I felt that it was not enough. Strong electricity: The project manager should plan the basic direction of strong currents (busbars and small cables). You need to know how big the distribution cabinet is and how much area the distribution room requires. As an outstanding talent in craftsmanship, you must have good computing ability, a good sense of three-dimensional space and size, and a general view of the overall picture. If you are a novice, you must first have solid basic knowledge. If not, then quickly make up for it. ； Go to the scene more ； Visit other manufacturers more often ； Communicate more with peers ； The last point is to work hard and learn more. There is no shortcut to success. In fact, I am also a novice.
