Chemical product production mode optimization method, device and continuous chemical system

Abstract

The invention relates to a chemical product production mode optimization method and device and a continuous type chemical system. The method includes the steps that firstly a first near infrared spectrum of online products of produced chemical products and a second near infrared spectrum of a check sample are obtained; secondly whether the contrastive analysis results of the first near infrared spectrum and the second near infrared spectrum are consistent or not is judged, and if yes, the operation parameter when the online products are produced is obtained; thirdly a production mode conforming to the quality standard of the sample is determined according to the operation parameter. By means of the method, the defects that the cycle is long, accuracy is low, samples are less and the frequency is low when chemical product quality is analyzed through laboratory equipment in a traditional laboratory in the prior art are overcome, the process operating data and the product quality inspection data which are originally like two information isolated islands are organically combined, and the production mode of high quality chemical products can be rapidly optimized.

Description

Technical field [0001] The invention relates to the field of chemical engineering, in particular to a method, device and continuous chemical system for optimizing the production mode of chemical products. Background technique [0002] In the chemical industry, especially in the field of polymer materials, especially in the field of chemical products, due to many factors that affect product quality, such as the ratio of materials and feeding speed, operating temperature, operating pressure, operating time, etc., the device will The occurrence of quality fluctuations makes it difficult for product quality parameters to be accurately constant at the same level, and it is difficult to meet the increasingly high quality requirements of downstream customers. [0003] figure 1 It shows a flow chart of analyzing the quality of chemical products by using traditional laboratory testing equipment in the prior art. This method is manual operation with low efficiency and few samples. The possi...

AI Technical Summary

Problems solved by technology

This method is manual operation with low efficiency, and few samples are collected, so the possibility of accurately finding the best production mode is extremely low, and the process operation data and product quality inspection data are stored in disconnected databases, becoming an "information island" ”, the analysis result has a hysteresis
