Fail-safety taken as a factor of completeness of using the resources of the production facility is important for characterizing the technological process. In most modern automated process control systems the above factor is implemented by means of the emergency protection system which allows to avoid the progressing emergency. However, such measures significantly increase the downtime of process equipment, since the possibility of developing pre-emergency and emergency situations when combining several permissible and close to emergency values of parameters is not taken into account. To solve the problem of reducing machinery downtime, a method for determining the object state indicator has been proposed. It takes into account all variants of the influence of technological parameters on each other as well as their combinations leading to the emergency progress. As well, the proposed solution helps to set the proximity of the operating mode of the production equipment to the threshold emergency, which greatly reduces the risk of emergency in situ, thereby reducing equipment downtime and economic losses. The method of determining the indicator of the state of the object is considered on the example of the stabilization block of hydrogenate catalytic reforming unit.
