Abstract

Abstract
Detecting the leaking valves in refineries and chemical plants, has great significance with production facilities as well as big influence on total costs. Besides total media loses reduction resulting in cost reduction, the preventive maintenance improves, bringing big number of tested valves as the elements increasing safety and reliability of the processing plants.
The results obtained by implemented valve leakage detection technique at BP operating sites, have shown that cost savings of $ 100.000 -200.000 per annum per site can be realised.
Acoustic emission detector model 5131 with D9203IS sensor is in use on the site of INA Rafinerija nafte Sisak since August, 1999. Monitoring system has been implemented to valves suspected on leakage during normal plant operation. The obtained results have been used as a very usefull information for planing maintenance shutdown, as well as man-power and spare parts. The savings realised by far outcome the purchase price of the very instrument amounting 22.560$.
