Safety management system of chemical enterprises
Ministry of Chemical Industry1991April 14
Article 2 All chemical enterprises (including chemical mines, chemical machinery and chemical infrastructure units) shall strictly abide by this system.
Chemical enterprise: any chemical method to change the composition or structure of substances or synthesize new substances belongs to chemical production technology, that is, chemical process, and the products obtained are called chemicals or chemical products. Early chemical products were produced by manual workshops, and later evolved into factories, gradually forming a specific production department, namely the chemical industry. With the development of productivity, some production departments, such as metallurgy, oil refining, paper making and leather making, have been separated from the chemical industry and become independent production departments.

Question 2: What is the overview of chemical industry in chemical enterprises?
(chemical industry)
I. Chemical Engineering and Technology
Chemical industry, chemical engineering and chemical technology are all called chemical industry for short. The chemical industry includes agrochemicals, chemicals, pharmaceuticals, polymers, paints, oils and fats, etc. They appear in different historical periods, each with different meanings, but they are closely related, infiltrated and continuous, and have been given new contents in their development. The early life of human beings depends more on the direct use of natural materials. Gradually, the inherent properties of these substances can no longer meet the needs of human beings, so various processing technologies have emerged, consciously and purposefully transforming natural substances into new substances with various properties, and gradually putting them into practice on the scale of industrial production. Broadly speaking, any chemical method to change the composition or structure of substances or synthesize new substances belongs to chemical production technology, that is, chemical process, and the products obtained are called chemicals or chemical products. Early chemical products were produced by manual workshops, and later evolved into factories, gradually forming a specific production department, namely the chemical industry. With the development of productivity, some production departments, such as metallurgy, oil refining, paper making and leather making, have been separated from the chemical industry and become independent production departments. With the rapid development of large-scale petroleum refining industry and petrochemical industry, based on chemistry, physics and mathematics, combined with other engineering technologies, chemical engineering was born and developed rapidly. It studies the laws of chemical production process and solves many engineering and technical problems in the process of production scale enlargement and large-scale, thus raising the production of chemical industry to a new level and entering a new stage of theory and prediction from an empirical or semi-empirical state.
In order to survive and develop, human beings constantly struggle with nature and gradually deepen their understanding of the surrounding world, thus mastering the ability to conquer nature and transform the world. After long-term historical practice, human beings are better at using natural conditions and creating a rich material world for themselves.
In ancient times, people's lives depended more on the direct use of natural materials or the extraction of what they needed. Because the inherent properties of these substances can't meet people's needs, then
A variety of processing technologies have been produced to transform natural substances into new substances with various properties, and gradually put them into practice on the scale of industrial production. Anyone who changes the composition or structure of a substance or synthesizes a new substance by chemical methods belongs to chemical production technology, that is, chemical process; The products obtained are called chemicals or chemical products. In this way, many substances that are not found in nature are continuously created. At first, this kind of products were produced by manual workshops, and later evolved into factories, gradually forming a specific production department, namely chemical industry. With the development of productivity, some production departments, such as metallurgy, oil refining, paper making and leather making, have been separated from the chemical industry and become independent production departments. With the rapid development of large-scale petroleum refining industry and petrochemical industry, chemical engineering based on chemistry, physics and mathematics, combined with other engineering technologies, has been further improved to study the laws of chemical production process and solve many engineering and technical problems in scale expansion and amplification. It raises the production of the chemical industry to a new level, and enters a new stage of theory and prediction from an empirical or semi-empirical state (see the history of chemical engineering development), which makes the chemical industry add a lot of material wealth to mankind with its creative ability of mass production and accelerates the development of human society.
In modern Chinese, chemical industry, chemical engineering and chemical technology are all called chemical engineering for short. They appear in different historical periods and have different meanings, but they are closely related and penetrate each other. In people's minds, the word "chemical industry" has habitually become synonymous with a general knowledge category and occupation. Its significance in national economy and engineering technology has aroused people's extensive interest, attracted thousands of people and sacrificed their lives for it. The following briefly explains the rich and colorful contents and important contributions of the chemical industry from all aspects of human social life.
Second, fine chemical industry.
Fine chemical industry is the production ... >>
Question 3: What does a chemical plant do? Chemical companies see whether you are a producer or a trader. If it is a production factory, it generally produces one or more raw materials of the same type of chemical products. Of course, the paint factory can also be called a chemical plant, which is too complicated to elaborate. In addition to selling products to domestic customers, domestic chemical plants also export some products. If the factory itself has no export right, it will be done through a trading company. Chemical trading companies can make n kinds of chemical products, but they can also be divided into two categories: organic chemicals and inorganic chemicals. Organic chemical raw materials are generally used in fine products, while inorganic chemical raw materials are generally used in industrial products. Specifically, sell it to those companies. Chemical raw materials are widely used, and the sales target is manufacturers who produce plastic products/paints/skin care products/daily chemicals/processed foods. Chemical trading companies usually export their products, and of course some also do domestic sales. At present, China's chemical industry is very mature, and its international export volume is also very large. If it succeeds, it will definitely make money. There seems to be less chemical industry in Harbin, which may be due to the climate. Some chemicals can't be stored in that climate, and transportation in winter is also a problem. You can't just be an internal market in Harbin!
Question 4: What do chemical plants do to make chemical products, such as oil refining (gasoline, diesel oil)? Plastic, fertilizer, etc.
Question: What does hseq mean in chemical enterprises? Health (h), safety (s), environment (e) and quality (q).
Question 6: What are the characteristics of chemical production? Dublin Core Technology Dublin Core is a short directory model developed by Dublin Core Metadata Initiative, an international organization, to identify electronic resources. As soon as it appeared, it was recognized by more than 20 countries in North America, Europe, Asia and Australia. Not only libraries and museums, but also many institutions and commercial organizations are adopting or preparing to adopt it. It comes into being because the producers get inspiration from the traditional way that library readers query and borrow the books they need through the card catalogue: searching for electronic resources on the internet, and also relying on the catalogue information reflecting these electronic resources. Therefore, the drafters of Dublin Core Set drew up 15 kinds of generalized metadata according to the model of library card catalogue. These data are: 1. Title ID: Title Definition: The name assigned to the resource. Description: Make the resource a well-known and representative official name. 2. Creator identification: Creator definition: the main responsible subject for producing resource content. Explanation: Creators and producers include individuals, organizations or institutions. It should be a representative name used to identify the creator and producer entity. 3. Theme and keyword identification: theme definition: the theme of resource content. Explanation: the key words used to describe the main content of the resource or the representative subject words represented by the classification number. 4. Description ID: Description Definition: Description about the content of the resource. Description: Description may include but not limited to: abstract, content, content icon or text description of content. 5. Publisher identification: Publisher definition: the responsible entity that plays an important role in production resources. Explanation: For example, it includes publishers of individuals, organizations or institutions. Should be a representative name used to identify the publisher entity. 6. Contributor identification: Contributor definition: the entity responsible for publishing resource content. Explanation: Issuers include individuals, organizations or institutions. Should be a representative name used to identify the issuing entity. 7. Date identification: date definition: date and time related to the service life of resources. Explanation: The date and time when the resource was effectively generated or used. It is suggested to use the encoding form defined by ISO 860 1[W3CDFT] after YY-MM-DD. 8. Type identification: type definition: characteristics or genre of resource content. Description: Types include descriptive terms such as category, function, genre or integration degree of works. It is suggested to select related terms from the controllable vocabulary (such as Dublin Core Types[DCT 1]). For the physical or digital representation of resources, format items are used to describe. 9. Format identification: format definition: the unique physical or digital representation of resources. Description: The format can include media type or resource capacity. It can also be used to define the software, hardware or other equipment needed for resource display or operation, such as the capacity including the space occupied by data and the life cycle. 10. identifier identification: identifier definition: identification information allocated to resources according to relevant regulations. Note: It is recommended to use the characters or numbers specified in the format identification system to identify resources. For example, the formal identification system includes Uniform Resource Identification (URI), Uniform Resource Address (URL), Digital Object Identification (DOI), International Standard Book Number (ISBN), International Standard Publication Number (ISSN) and so on. 1 1. Source identification: Source definition: information about existing resources can be obtained. Description: Existing resources can be obtained in whole or in part from original resources. General signs are recommended ... >>
Question 7: What does a chemical plant do? Chemical plants use physical chemistry and chemical processes to produce products.
Question 8: What does petrochemical production do? Mainly engaged in chemical, petrochemical, (pharmaceutical) industry engineering design, engineering consulting, engineering supervision and other work, it is not clear whether this question is to apply for or what, if not, the above explanation should be clear, mainly what their work is.
