Abstract

This article introduces the Comprehensive Resilience Assessment Framework and Techniques (CRAFT) for evaluating resilience in chemical process plants, illustrated by a case study on a methanol production unit. The framework integrates both technical and social resilience aspects, categorized into specified and general indices. It evaluates resilience through four primary indices: Specified-Technical resilience (Ist), General-Technical resilience (Igt), Specified-Social resilience (Iss), and General-Social resilience (Igs), utilizing quantitative and qualitative methods. For the methanol unit, the Ist dimension is calculated as 0.499, reflecting key factors such as the impact of hazardous substances, and the high operational pressure and temperature in the reactor. The Igt dimension, based on flexibility and consequences indices, is determined to be 0.780, indicating a robust ability to adapt to feed flow rate changes and equipment performance variations while maintaining low environmental impacts. Social resilience, assessed through expert questionnaire, yields scores of 0.727 for Iss and 0.769 for Igs, highlighting moderate preparedness in areas such as collaboration, communication, and adaptability. Considering these indices, the overall resilience of the methanol unit is 70.3 %. This novel, systematic approach supports decision-makers in enhancing safety, efficiency, and environmental performance in both routine and disruptive scenarios.
