Description

technical field [0001] The invention relates to the technical field of coal tar distillation range analysis, in particular to a coal tar component analyzer. Background technique [0002] In order to accurately understand the actual content of different substances in coal tar, and at what temperature they can be separated and used, so as to adjust the control conditions in production according to the actual situation, it is necessary to conduct detailed analysis through coal tar distillation experiments. During the experiment, precise temperature control is very important. [0003] The distillation range analysis of coal tar includes the determination of the composition structure, the content of each component and the distillation range. At present, most of the analysis and determination work is still done manually by chemical analysis and distillation. Coal tar products have thousands of distillate substances during the distillation process, of which only dozens of varietie...

Problems solved by technology

[0004] In the process of determining the distillation range of artificial distillation, the experimental operators use the naked eye to observe and record key parameters such as the initial boiling point, final boiling point, and dry point in the distillation range. The distillation range curve is also calculated and drawn manually. Due to the low accuracy of manual observation , slow speed, and many human-influenced factors make it difficult to guarantee the accuracy of the measurement results

For this reason, some large coking enterprises also conduct gas chromatographic analysis to determine the product composition structure, and the drawing of their distillation curves mostly adopts the method of establishing mathematical models, or uses the multiple regression method to establish the chromatographic curve of the distillation range of benzene, because These measurement processes are obtained by means of simulation, and there is still a certain gap from the real results. Therefore, it takes a long time of experience accumulation to achieve precise control of the determination of the distillation range of one of the media. If you want to master dozens of The law of determination of the distillation range of coking substances, the complicated process and the time cost can be imagined
