Aged catalyst can degrade process performance:

• Increasing raw material consumption
• Creating more byproducts
• Increasing utility costs
• Limiting production capacity

Know when to replace / upgrade your catalyst, or adjust make-up rates

Periodic Replacement

Continuous Replacement

Whether heterogeneous or homogeneous, some catalysts are meant to stay in service for years.  Their replacement is a significant investment which pays back with improved process performance.
Process Evaluations LLC can help you determine when catalyst replacement is justified, and develop a strategy for optimal replacement periods.

Fluid bed reactors and some homogeneous catalyst systems continuously replenish their catalyst, creating an age distribution of catalyst in service. 
Process Evaluations LLC can help you optimize catalyst make-up cost versus improved process performance
