Fluid Catalytic Cracking (FCC) Optimization

Expand fluidized catalytic capacity and conversion with oxygen enrichment

Expand Fluidized Catalytic Capacity and Conversion with Oxygen Enrichment

FCC oxygen enrichment can provide the following process benefits

0740-gear
Helps to overcome air blower capacity limitation

The addition of oxygen to the combustion air offers a practical solution to increasing the capacity of a blower-limited catalytic cracker

ap0113-ladder
Overcomes regenerator velocity limitation

Reduction of air blower rate followed by the addition of oxygen can increase the capacity of a velocity-limited catalytic cracker

0795-gauge
​Improves yield

Higher oxygen level in the regenerator air improves coke removal and thereby increases the yield of the higher value light-end products

0884-ruler
Helps to maintain capacity on a seasonal basis

Higher oxygen level in the combustion air can counter the problem of reduced FCC capacity when high ambient temperatures and humidity decrease air blower output

1040-check-mark
Reduces flue gas velocity

Addition of oxygen helps to minimize regenerator vapor velocity, which can help increase production without the additional catalyst loss or cyclone erosion normally associated with higher throughput.

0796-clock
​Increases time between turnarounds

Lower gas velocity reduces wear and tear on FCC's cyclones

0959-thermometer
​Improves temperature control

A well-designed oxygen flow control system can allow for simple and precise adjustments for changes associated with day-to-day FCC operation

1093-lightning-bolt
Helps to overcome operational feedstock challenges

Higher oxygen concentration in FCC can increase temperature when lighter feedstocks are used or it can help with handling extra carbon formed on the catalyst in the regenerator when heavier feedstocks are used
