| Abstract |
With the rapid development of my countrys economy, the chemical industry, as an important economic pillar, has a higher status in the national economy, and there are more and more chemical plants. In the process of chemical production, based on the physical characteristics of the medium in the pipeline, process requirements and external environment requirements, it is necessary to take certain insulation measures for the process pipeline or equipment to ensure the normal operation of chemical production. At present, the thermal insulation and antifreeze of materials in chemical production in my country mainly adopt two kinds of heat tracing systems: steam tracing and electric tracing. The two types of heat tracing systems are different in working principle and operation and maintenance measures to be taken, and based on the difference in equipment, materials, external environment and operators, which heat tracing system to choose will have a greater impact on the operation and investment costs of the device. difference. Therefore, choosing a suitable heat tracing system in a chemical plant will help to improve the economic benefits of the project. This paper mainly analyzes the working principles of two heat tracing systems, steam tracing and electric tracing, and compares their applications in chemical engineering. And pointed out the specific differences between the two in the application of chemical engineering, for the reference of chemical practitioners.
