中文摘要 | This study analyzes and conceptualizes Reliability Centered Maintenance (RCM) applications for calculating the probability of equipment failure modes in order to gauge the impact of failure modes on the cost of impeded production and to further understand the failure risks attached to various failure modes. High/medium/low failure risks can be utilized to determine the optimal maintenance strategy for effectively reducing failure risks and the loss of equipment in the key system of a petrochemical refinery. Risk analysis in the study of failure modes can provide a better understanding of the risk distribution needed to facilitate overall maintenance of both low-risk and high-risk equipment. Ultimately, this study will enhance the reliability and productivity of such plants. Typically, the equipment is made up of a compressor system that includes a pump, turbine, cooler, tank, instrument cells and other various components. Coincidentally, a key compressor system also accounts for a large portion of the production loss. Following detailed analysis of the reliability of failure modes, the economic influence and outcome of two compressor systems in a petrochemical refinery, and the risk distribution rate, we discovered that 5% of the equipment from both compressor systems accounted for 90% of the risk ratio. This indicated that it is possible to control most of the risks by merely controlling a small number of high-risk items. Furthermore, with the data gleaned from the failure modes of high-risk equipment, we can ascertain the causes of these failures, perform root cause analysis, and effectively run a comparison between the investments in risk and the maintenance costs. To begin the study, the optimal maintenance strategies are set forth in the analysis presented here. |
英文摘要 | 本文主要參考可靠度方法論的應用。求取設備失效模式發生的可能機率,以及失效模式發生導致生產中斷成本的影響性,進而瞭解各失效模式的失效風險。由失效風險高中低來決定最佳化的維修策略,以達到有效降低石化煉製廠關鍵性設備失效風險及損失。藉由失效模式風險分析的研究,瞭解風險分佈的情況,以避免低風險設備過度的維修及高風險設備維修不足的情況,進而達到工廠可靠度提昇的目的。 通常壓縮機系統是由許多設備組合而成,例如泵、透平機、冷卻器、油箱及其他機件等等。針對石化煉製廠中二個關鍵性壓縮機系統作失效模式可靠度及經濟後果影響性之分析研究,並探討風險分佈比例。分析中發現二者皆有5%設備佔有超過90%風險比例的趨勢,亦證明了主要掌握少數高風險項目即能控制大部份風險發生的可能性。此外,更進一步的分析高風險設備失效模式之實例探討,瞭解其失效原因,根源分析及風險和維修成本投資比較,且特別針對維修策略最佳化做討論並於文中說明。 |
