The liquid product H in stream 9 is considered as quality variable while 22 process variables XMEAS (1) – XMEAS (22) are selected as process variables. 960 samples are collected as training samples, and another 960 samples are collected as the test dataset in the same working condition.
TE benchmark is a chemical simulation platform, which is widely used to evaluate the process monitoring performance of different soft sensing models. The process is mainly composed of five units: reactor, condenser, compressor, separator, and stripper, involving 41 measurement variables and 12 control variables. In TE process, different units organically cooperate with each other. Since various control strategies are implemented, a part of the variables can be autocorrelated while others are not.
