Determinación de la frecuencia óptima de parada de la planta de destilación atmosférica ubicada en el bloque 16 de Repsol para el mantenimiento preventivo

Abstract

It was determined that the optimal time of shutdown atmospheric distillation plant for the total preventive maintenance, because of currently it runs in based of manufacturer´s recommendation. It was explained the methodology of Inspection Based on Risks supported as recommended by the API-RP580/581 standard ensuring the mechanical integrity of static equipment involved in the process practice explained, characterizing the risk associated with the components subjected to corrosion based on the historical behavior of faults, design features, operating conditions, fluids, maintenance, inspection, and management policies. The qualitative study represents a rapidly nesting risk trough the matrix between different teams and with the semiquantitative analysis is a deeper analysis to quantify the rate of corrosion and remaining life, allowing us to determine the frequency of inspection. Like complement is performed the study of historic fault that influence plant shutdown by determining the mean time between failures MTBF more significant. Additionally the equipment efficiency is most important as determined to verify like its performance affects plant versus time. From the analysis of the optimum frequency for preventive maintenance was determined.
