The efficiency of oil-refining industry is determined in a great measure by the amount of material resources and labor force overhead for the repair of equipment and by the amount of losses from accidents and unit downtimes. The wear rate of the equipment is largely determined by the adequacy of impact on it from production and service personnel. It is necessary to control operating costs and equipment resources. For this effect it is essential to provide observability of the industrial complex condition through its monitoring, i.e. the monitoring of the equipment condition to determine the current condition and predict the moment of equipment`s transit to the limiting state.
The results of the monitoring present diagnoses, gathered from monitoring objects of the manufacturing complex, that are obtained by inseparably adjacent time intervals, when the condition of the equipment does not change significantly. Choice and substantiation of the monitoring object is carried out by analyzing the technological scheme of the plant and the scheme of process units, taking into account the impact of their failure (shutdown or power reduction) on the technological process and the explosion and fire risk across the enterprise. As a result we can define the hazard categories, which are subjected to be equipped with the condition monitoring system in accordance with our program of equipping the enterprise with monitoring systems and the transition to condition-monitored operation of the equipment.
The process equipment of refinery units includes dynamic (pumps, compressors, blowers, air coolers, etc.) and static (columns, tanks, pipelines, etc.) equipment, different technical means are often used for its diagnosis and monitoring. The global trend to use the overspecialized technology of stationary and portable diagnostic tools for the specific type of equipment has led to the creation of a large variety of systems produced by different companies and almost incompatible with each other, that does not allow to integrate them into one information space - ACS of enterprise.
An example of a comprehensive approach to condition monitoring of process units refinery equipment is the COMPACS® system, which provides observability of dynamic and static equipment of essential main process units of "Angarsk Petrochemical Company" JSC on an one hardware and software platform with the transfer of the results of monitoring into an integrated diagnostic network Compacs-Net®.
