Measurement and Testing INCREASE FCC PROFITS: THE CHALLENGES
FCC Application FCC Operational Needs: • Refi ners need to be fl exible with feedstocks. • Refi ners need to accommodate feedstock variability. • Does the VDU provide enough feed? • Are open-market feedstocks available? Useable?
• What are the concerns of feedstock variability on catalyst performance and lifetimes? • Does FCC throughput meet production demands • Are product distributions optimized?
• Switching to heavy crude oils increases the production of heavy distillates to be further cracked by the FCCU (Fluid Catalyst Cracking Unit) into lighter fractions.
• FCCU process optimization is a complicated task requiring the utilization of both process and economic variables.
• FCCU process optimization software adjusts operation parameters based on the availability of analytical data. Critical real-time property measurements, especially on FCCU feeds are often unavailable, as they rely on a static database.
• Real-time on-line monitoring is critical in the optimization of the FCCU process. 4IR’s AI-60 Analyzer provides game changing technology which enables real time analytical data.
