What are the differences between chemical engineering design for fine pharmaceuticals and chemical engineering design for petrochemicals, and which one is better?

In a broader sense, it’s more or less the same. On a smaller scale, it makes sense. In accordance with the Ministry of Construction’s \"Standards for Engineering Design Qualifications\" No. 86, the exact designation for this industry is the \"Chemical, Petrochemical, and Pharmaceutical Industry.\" Within this industry, in addition to \"Grade A\" and \"Grade B\" classifications, there are also 9 specific types of professional design, including: oil refining engineering, chemical engineering, storage and transportation of petroleum and chemical products, chemical mining, biochemical/biopharmaceuticals, chemical active pharmaceutical ingredients, traditional Chinese medicines, pharmaceutical formulations, and medical devices. Within each professional qualification, there are further subcategories of Grade A and Grade B. Therefore, based on the above classifications, it is possible to lean towards petrochemical engineering design, but upon further breakdown, there are still specific considerations regarding the specialized areas. If you are majoring in process engineering, it is more suitable to work at design institutes that have industry qualifications or expertise in petroleum refining engineering or chemical engineering.

Now, many chemical and petrochemical design institutes are also expanding into the light textile industry, undertaking services such as those in the field of daily chemicals, salt chemicals, chemical fiber raw material processing, and chemical fiber manufacturing. There are also light textile institutes that have expanded into the petrochemical industry. Generally speaking, in the field of chemicals, chemical and petrochemical design institutes have stronger overall capabilities than light textile design institutes.

With very few exceptions, China Kunlun Engineering Company, a subsidiary of CNPC, was restructured from the former China Textile Industry Design Institute.

]mm0528: I’ve heard of this classification system for industries and professions for the first time, but I understood it right away after seeing it. Thank you! In fact, design qualifications are divided into four categories: “comprehensive, industry-specific, professional (including architectural firms), and specialized”. Some design firms that possess specialized or professional qualifications tend to use vague statements when promoting themselves and exaggerate things, just like that person who said, \"I’m from Lianhua Township, Tieling, a big city; my name is Yadan.\"”

In the pharmaceutical and chemical industry, batch processes are common. Small scale. Low pressure, low temperature. The device is small. In the petrochemical industry, processes are generally continuous. Large scale. High temperature and high pressure. The equipment is large. In the pharmaceutical industry, even a pressure of a few kilograms is considered quite significant; in the petrochemical industry, pressures of dozens or even hundreds of kilograms are something common.

I joined an engineering company that works in the chemical and pharmaceutical industries. What would I say? “Pipes smaller than 10 inches,” “low pressure of 12 kilograms”... They all think those are very large and high.

Different industries have different requirements, right? The pharmaceutical industry must have higher standards and greater safety requirements, I guess
