RAM analysis for refinery process design optimization

RAM refers to reliability, availability and maintainability analysis. The RAM model uses discrete event simulation (DES) software and provides a quantitative assessment of the performance of an industrial plant. This article discusses the use of RAM analysis on petroleum refinery projects to select an optimum process configuration and associated storage requirements.

RAM refers to reliability, availability and maintainability analysis. The RAM model uses discrete event simulation (DES) software and provides a quantitative assessment of the performance of an industrial plant. This article discusses the use of RAM analysis on petroleum refinery projects to select an optimum process configuration and associated storage requirements. The RAM model for an overall refinery includes all major process units, intermediate storage tanks, interconnect routings, and operating logic defining normal operation and actions upon process unit failures. The model calculates individual process unit onstream factors, assesses the intermediate tankage requirements, and provi
