Anyone who produces polyester produced by chemical fiber companies can come in.

Hello experts, it is understood that almost all polyester production lines now pay great attention to the esterification rate, which is usually obtained through laboratory analysis. This has the disadvantage of time lag. If it is possible to detect the esterification rate online, do you think it will have any guiding significance for production?
Our online inspection is to carry out differentiated design for the production process and on-site working conditions of each set of equipment, and to conduct individual modeling based on material characteristics. I would like to ask whether the design institute here does the polymerization process design or the chemical plant production workshop does the process analysis?
No, I work in chemical sales. If factories have requirements for the consistency of their products, they must require online monitoring. The consistency of continuous production is generally calculated using variance, but it seems that they don't know how to calculate it. I have contacted so many manufacturers, and only one uses cpk value to assess process control.
