In chemical production, chemical analysis and chemical testing is a more important part of chemical production monitoring, the degree of reaction, and whether the mutual media meet the safety indicators for analysis and inspection, can effectively maintain the safety and stability of chemical production, improve the quality of chemical production. Based on this, the article mainly discusses the connotation of chemical analysis and inspection, and its function
First, chemical analysis and chemical inspection overview
(1) Chemical analysis
Chemical analysis can be divided into chemical analysis and instrument analysis, the two are scientific substance detection methods, and chemical analysis is the application of these two scientific methods in chemical production. Chemical analysis is absolutely quantitative, according to the amount of sample, the amount of reaction products or the amount of reagents consumed and the stoichiometric relationship of the reaction, by calculating the amount of components to be measured, is the detection method to study the composition of substances.
1. Chemical analysis. Chemical analysis is divided into qualitative analysis and quantitative analysis as to whether the quantity is accurately determined. Qualitative analysis is an analytical method to determine whether a component is present in the substance under test, usually to determine whether the substance has a certain element, ion, or organic component. Quantitative analysis requires accurate measurement of the relative content of the various components of a substance. Due to the determination of the principle of chemical production, the basic composition of the material is usually understood, the goal of quantitative analysis is generally to determine the composition of raw materials, as well as intermediate products in the production process, the final product to determine, while the auxiliary materials, such as water and fuel quantitative analysis, master the production process.
2. Instrument analysis. Instrumental analysis refers to the use of special instruments to conduct qualitative analysis, quantitative analysis, morphological analysis of substances, and the use of experimental phenomena that can directly or indirectly characterize various characteristics of substances (such as physical, chemical, physiological properties, etc.). Information about the composition, content, distribution, or structure of a substance that can be directly sensed by a probe or sensor, an amplifier, an analytical converter, etc. This method appears later than chemical analysis and is more convenient to use.
(2) The main contents of chemical inspection
Chemical inspection is another important part of chemical production. Chemical inspection, as its name suggests, is to inspect various links in chemical production, which has an important impact on the quality and production efficiency of chemical production. In the process of chemical production, a small part of the chemical products produced cannot meet the corresponding standards, and these chemical products that do not meet the standards will affect the overall quality of chemical production. Chemical inspection is to strictly inspect the products in each production process of chemical production, and check the chemical products that do not meet the standards. It makes the qualified rate of chemical products reach a higher level. Paying attention to chemical production inspection is an important means to improve the level of chemical production in our country at present, and only the chemical inspection work can be carried out smoothly to ensure the final result of chemical production. With the improvement of the level of chemical industry, the quality requirements of chemical products are more improved, so chemical inspection is more important for chemical production at this stage.
Second, the important role of chemical analysis and chemical inspection
(1) The important role of chemical analysis
Chemical analysis has a wide range of applications in the development of the present stage, not only in the chemical production process has an important application, but also in other production has an important role.
1, the role of chemical analysis and production. In the specific production process, the consumption of materials and the production of intermediate products are more complex, and often there is a gap between the ideal results, in order to reduce costs, increase production, and protect production equipment, it is necessary to use chemical analysis methods to analyze energy fuels and chemical raw materials in order to reasonable ratio, reduce the unreasonable loss of materials and power, and improve economic benefits. The detection of raw materials can determine the quality of raw materials in time, which is easy to control the process in production, and the analysis of intermediate products and final products can give feedback on the production process and process, timely reduce the generation of waste and defective products, and improve product quality.
2, chemical analysis in? The role of waste management. In chemical production, the generation of waste is also an important problem, unreasonable treatment will cause serious environmental pollution and safety accidents, the damage to the equipment can not be ignored. The use of chemical and instrumental analysis methods to analyze the "three wastes" materials, improve the reuse rate, and timely monitor the leakage medium can effectively reduce environmental pollution, reduce the cost of safe production, and avoid serious accidents such as explosions and fires, so that the safety of production personnel has a better guarantee, and the long-term use of equipment also provides reasonable feedback to produce qualified products. Civilized and safe factory operation provides scientific guarantee.
