Prototype of Digital Twin of Isopropylbenzene Hydroperoxide Decomposition Process for Phenol and Acetone Production

For the unit of decomposition of isopropylbenzene hydroperoxide of the process of phenol and acetone production the prototype of the digital twin on the basis of the created neural network model is developed, which allows to calculate online the outputs of main and by-products, energy resources and conditional profit with relative error not more than 0.73%. Formation of a database of values of technological process parameters is carried out with the use of simulation modeling of plant operation and subsequent verification of model adequacy by comparing the obtained calculated results with the actual values of technological parameters. As a prototype of the digital twin, allowing to determine optimal values of the cumene process parameters of isopropylbenzene hydroperoxide decomposition unit in the online mode, it is proposed to apply the microcontroller ESP-8266 with built-in and developed program written in the language C.
