Improving the refineries operational efficiency based on equipment condition monitoring

Print

In the course of long-term theoretical and experimental researches the condition monitoring system for the refinery machine and column-storage equipment, which implements the concept of the real-time equipment operation on its technical condition, has been developed. High-precise diagnostics, built-in expert system for recognition of the defects main classes ensured the effective monitoring and the equipment technical condition forecast with an automatic issuance of regulations on equipment maintenance and their execution control. Refineries equipping with such monitoring systems increases safety and operational efficiency, as convincingly shown by the results of its maintenance: a significant reduction of sudden failures, a fourfold decrease of repairs, and the total savings from the implementation of the monitoring system are more than $6 million per year along with 1,5 months payback period.

The article shows a cause-and-effect relation between the situational costs increase, depending on the observability of the equipment condition, and the personnel actions. The analysis of the typical refinery equipment condition and its repair is shown. The concept of the equipment condition monitoring is revealed. The application of the comprehensive monitoring system COMPACS® is described to ensure the safe equipment operation on hazardous industrial facilities by real-time receiving the operational information about past, current and projected technical condition of equipment. The SM™-technology use in refineries production management has been presented.

Orthogonality of vibroacceleration, vibrovelocity and vibrodisplacement signals in vibration analysis tasks

Print

Search and application for an estimation of a technical condition of machines of orthogonal diagnostic attributes represents rather actual problem as essentially increases reliability of diagnostics. Experience shows, that development of various malfunctions of rotor machines leads to that parameters vibroacceleration, vibrovelocity and vibrodisplacement react to these malfunctions on a miscellaneous. In a practice of vibration analysis and vibrocontrol the signals of vibroacceleration and vibrodisplacement often do not use, including their closely connected with a signal vibrovelocity, that these parameters are connected among themselves by differential-integrated ratio. These cases specify significant narrowing of a range of diagnosed malfunctions at use only one of these parameters.

By analytical researches, by numerical computer modelling and by means of natural experiments it is shown, that at diagnosing such malfunctions as defects of rolling and slidings bearings and, impellers of pumps, tooth gearings, infringement of centering of machines and fastening of units of machines to the bases, among themselves and to other attached designs, vibroacceleration, vibrovelocity and vibrodisplacement it is possible to consider parameters practically orthogonal. Thus, sharing for diagnostics of all three, parameters allows to observe in a spectrum of fluctuation of all frequencies raised in the mechanism.

The system of acoustic emission monitoring of hazardous production facilities

Print

Recently, one of the most effective methods of condition monitoring is acoustic emission monitoring. Its potential with minimum tool and staff costs can not only detect and record emerging defects, but also classify them according to hazard level. The ability of acoustic emission method to register the slightest structural failure of the material can monitor not only test subjects state but also objects in operation without changing their operation schedule.

The experience of acoustic emission monitoring of various objects using the multichannel acoustic-emission systems, as well as experience of developing information-measuring systems allowed to develop and successfully implement the system COMPACS® for acoustic emission monitoring.

The system provides reliable recording of signals in a high level of industrial noise, allows integrally evaluate state of objects, provides to localize sources of acoustic emission - areas of origin and/or growth of defects. Built-in calibration system provides functional test of ducting system, sensors truth and localization system setting.

Estimating the efficiency of repairs to oil refineries

Print

The theory of economic analysis states that any increase in constant costs leads to growth of break-even cost, so it is necessary to make and encash additional products to cover them. The increase of variable costs produces the same effects, but even their slight rise leads to much greater operation lowering of the refinery due to the effect of operating leverage, as the loss of raw materials, energy, and the finished commodity directly affect the value of variable costs and marginal revenue. Such factors as intensity of use, energy consumption and labor intensity influence the loss of resources. Such figures are determined by production methods and can`t be changed without changing of them.

Therefore, the main reason of raw materials, energy, and finished commodity losses during production is equipment failures caused by operation schedule failures, or intolerable state of production facilities. This leads to a suspension of production, faulty production, and in some cases, the destruction of material resources, including raw materials, finished commodity and fixed assets. Size of situational costs depends on the amount of material and labor costs to the equipment repair and the amount of losses from accidents and downtime.

Thus, the main vector of the cost-effective use of resources in the enterprise is prevention of growth and decrease of situational costs that appear during the production, which allows save material, labor and financial resources of the refinery, as well as cut losses of other types of resources - human, environmental, etc. Moreover, the decrease of situational costs allows increase the duration of the production and reduces schedule shutdowns.

On-line monitoring of motor driven rolling stock

Print

Monitoring motor driven rolling stock is monitoring of electric assemblies to determine and predict the moment of their transition to the limit state. This is accomplished by periodically diagnostics of adjacent time intervals which are significantly shorter than the failure interval to a critical value.

Automatic monitoring - is an automatic comprehensive diagnostics of technical condition with the required completeness (covering at least 80% of the main faults), spread in time and available to the staff at all levels to make reasoned decisions. This approach allows us to control the state of MDRS by timely maintenance and repair, i.e. maintain and repair only those units which need to be repaired in the upcoming period of operation.

Automatic diagnostics is possible only together with automated expert system fault location, which eliminates the human error of diagnostician and reduces the labor intensity and period of diagnostics.

Linking all diagnostic systems at the depot and on-board devices of sections into a single monitoring system provides timely information about the technical condition of operated and repaired units and train in general, to the responsible staff of depot (plant). At the same time the following problem are solved: significantly decrease of human factor and minimization of errors to a level limited by accepted diagnostic methodology, decrease of labor intensity and duration of diagnostics, providing a small interval of diagnostics and minimization the dynamic errors.
