تجزیه و تحلیل حالات نقص تجهیزات فرایندی در یک صنعت شیمیایی
Authors
Abstract:
Background and aims Prevention of potential accidents and safety promotion in chemical processes requires systematic safety management in them. The main objective of this study was analysis of important process equipment components failure modes and effects in H2S and CO2 isolation from extracted natural gas process. Methods This study was done in sweetening unit of an Iranian gas refinery. Failure Mode and Effect Analysis (FMEA) used for identification of process equipments failures. Results Totally 30 failures identified and evaluated using FMEA. P-1 blower's blade breaking and sour gas pressure control valve bearing tight moving had maximum risk Priority number (RPN), P-1 body corrosion and increasing plug lower side angle of reach DEAlevel control valve in tower - 1 were minimum calculated RPN. Conclusion By providing a reliable documentation system for equipment failures and incidents recording, maintaining of basic information for later safety assessments would be possible. Also, the probability of failures and effects could be minimized by conducting preventive maintenance.

توسعه یک پایگاه دانش برای تجزیه و تحلیل حوادث فرایندی
Background and aims: One of the most applicable methods in the accident investigation process is utilizing the previously occurred accidents. Usually these data are collected in the databases. The customary databases have some limitations like inability to understand the relations among data. In the current study, it has been considered to provide a sound resource for accident investigation, b...

زمینه و هدف: یکی از روش های مورد استفاده در بررسی حوادث، استفاده از داده های حوادث گذشته است. این داده ها معمولا در پایگاههای داده گردآوری شده اند. پایگاههای داده فعلی دارای محدودیت هایی نظیر عدم توانایی درک ارتباطات بین داده های مستقل از هم هستند. در این مقاله سعی شده است با ایجاد یک پایگاه دانش برای حوادث فرایندی، ضمن تجمیع دانش مربوطه، منبع مناسبی برای انجام فعالیت بررسی حوادث ایجاد شود. در ...
