CREATION OF SAFETY ENCLAVES FOR THE INDUSTRIAL NETWORK OF THE STEAM-HYDROGEN METHANE CONVERSION PROCESS

Abstract

In the article, creation of safety enclaves for the industrial network of the steam-hydrogen metan conversion process, authored by Sytnikov O. V., Kvitka O. O., Zhlobinska K. U. and Onyshchenko D. S., the task of developing a network structure for protecting enclave perimeters in the context of their connection and determining criticality is presented.The network structure is presented, consisting of three main levels, each of which allows performing specific tasks: corporate, operator, production.A general description of the process of steam-hydrogen conversion of methane is given. It is indicated which circuit will be considered in the studies – the natural gas compressor network, since it is from the stage of supplying natural gas compressed in the compressor to the required pressure to the next heater device that the production process itself begins.The network is divided into functional groups, which will be based on circuits, corresponding connection rules and according to network levels. The studies were guided by the principle that functional groups correspond to the specified network levels, and therefore devices belong to a specific group if they are located in a common subnet defined for them.It is stated that from a statistical point of view, accidents in production most often occur due to deviations of technological parameters from standard values. Since these types of accidents lead not only to the production of defective products, but also to production accidents with consequences for employees, a higher level of criticality should be set for the technological installations themselves, similar to the highest level.The principle of determining perimeters is presented, which corresponds to the level of the scheme – corporate, operator, production network, compressor control subsystem. As a result of the research, a scheme for protecting the perimeters of enclaves in the context of communication between them is presented and programmed, indicating the appropriate means of monitoring data flows. Based on the results of the research, a request for the selection of technical and software cybersecurity tools is created.
