A New Approach to Fire Safety System in the Process of Atmospheric Rectification of Oil

: This paper presents the methods of detection and diagnosis of failures, that is, detecting the existence and causes of failure that can be applied in systems that operate in real time. The proposed system allows automatic and semi-automatic security management, and provides general average or minimizes the consequences of disasters. In addition, it de fi nes the conditions, i.e. the intervals of parameter values, under which causes of failure are created. Based on these parameters, optimal design of protection is possible and it enables the ef fi cient management of the system. Suggested fi re safety system in the process of atmospheric recti fi cation of oil offers the possibility to choose an optimal diagnostic algorithm and its practical and economic usage. A new approach should be applied in order to reduce fi re hazards in the process of atmospheric recti fi cation of oil. Fire safety system should be inseparable from the technological process, and vise versa. The procedure recommended for fault detection and diagnosis consists of two phases. The fi rst phase involves the assessment of the process state, while the second involves the identi fi cation of the values of processing parameters and their correlation with the process model parameters.
