Prompt engineering: Extracting operational excellence knowledge from AI—Part 2
Prompt engineering elaborates precise instructions to guide large language models towards generating specific, desired outputs, and offers significant potential for optimizing processes, solving complex problems and improving operational efficiency in refineries and petrochemical plants. In Part 2, the practical applications of these advanced prompt engineering techniques in various aspects of refinery operations will be explored. Examples include key areas where RAG implementation with specific plant information would be highly beneficial.
Prompt engineering: Extracting operational excellence knowledge from AI—Part 1
Prompt engineering is an emerging discipline at the intersection of AI and process engineering and will undoubtedly contribute to the hydrocarbon and green molecules processing industries. Parts 1 and 2 (October 2024) of this article explore and provide a glimpse of how this technique can help process engineers and operators to manage the power of advanced AI models to optimize processes, contribute to solve complex problems, and improve operational efficiency in refineries and petrochemical plants.
