Innovative methods of neural reconstruction for tomographic images in maintenance of tank industrial reactors

Many chemical engineering products are created as a result of processes carried out using technological lines in which chemical reactors play a key role. A chemical reactor is a vessel adapted to carry out reactions taking place inside it. The purpose of industrial tank reactors is to ensure optimal economic parameters of chemical processes [18]. It can be achieved by the appropriate reactor design and by the skillful overlap of the three types of sub-processes occurring inside the reactor, namely the transfer of mass, momentum and heat. In this way, process control can be based on a dynamic selection of parameters such as: mixing intensity, temperature, pressure, substrate ratios and others. The presented research included reactors in which reactions take place between solid and liquid as well as gas and liquid. The tank reactor diagram is shown in Fig. 1. The first type of reaction concerns the crystallization of solids in a liquid environment. It covers industrial processes of synthesis and purification of solid substances and changes in particle properties. The reactors in which crystallization occurs are used in many branches of the economy, including: chemical, food [9], metallurgy and waste utilization [27]. One of the monitoring systems tasks of such processes is to provide precise information on the quantity, size and location of crystals formed in the liquid in real time. The second type of reaction relates to the gas phase and the liquid phase. Such processes type are used, inter alia, in the production of biogas. Physicochemical fermentation reactors are a key element of biogas installations. Methane fermentation of organic waste takes place inside these reactors. The correct operation of technical systems is one of the crucial conditions for obtaining an adequate level of reliability of industrial processes [10]. There are two main reasons to monitor the state of dynamic processes. The first one is the detection of impending failures [11] which RymARczyk T, kłosowski G. innovative methods of neural reconstruction for tomographic images in maintenance of tank industrial reactors.
