Are you looking to make your processes more efficient and meet increasingly stringent environmental regulations, without making significant capital investments? Choosing the right gases and technologies for your refinery is key to reaching optimal productivity levels.
Adding oxygen to a Claus process helps increase plant productivity and overcome bottlenecks. It may also increase ammonia conversions in the burner muffle. Additional benefits include lower CAPEX required for sulfur recovery unit (SRU) expansion and the ability to handle more sour gas streams.
Oxygen enrichment in a fluid catalytic cracker (FCC) regenerator allows the possibility of getting more performance out of the same catalytic reactor section. This may lead to an increase in the capacity or the yield of gasoline in the FCC – by reducing the residual coke level – hence increasing the activity of the catalyst. In addition, you can decrease your blower load while maintaining oxygen levels, or overcome blower limitations in the summer. This will also allow the use of heavier crudes.
Volatile organic compounds (VOCs) in vent streams can be recycled or appropriately disposed of by using Messer's CRYOSOLVTM cryogenic condensation system.
