Hydrocracker Performance Optimization and Catalyst Remaining Life Assessment: Methodology and Case Studies

Abstract Hydrocracking has assumed immense importance in present day refining due to stringent environmental regulations for improvement in the quality of fuels and lubes. The hydrocracker units need to be operated optimally to sustain refinery profitability. An integrated methodology has been developed through a combination of a pilot plant and process model for better prediction and monitoring of the performance of commercial hydrocracking units. Three case studies on performance monitoring and optimization, catalyst remaining life assessment and its optimum utilization, and selection of a new catalyst system for commercial hydrocracker units are presented in this article to demonstrate the efficacy of the approach. The studies have led to significant benefits to refineries.
