Inlet Air Cooling
Enhance FCC Unit Performance with Air Cooling
Push your productivity through the summer months
Main air blower (MAB) constraints can be a headache for even the most equipped refiner. The MAB is responsible for ensuring optimal product output is generated from the FCC unit and is fundamental to successful yield production. When an MAB cannot cope with its surroundings, it can be a financial risk.
If the air mass flow rate is reduced, the severity of the cracking must be reduced, consistent with the ability to burn off the accumulated coke. This is usually accomplished by lowering the feed charged to the unit. When this occurs, the only real short-term solution to increase the FCC feed rate is to decrease the air inlet temperature to increase the mass of the air volume.
Aggreko's Process Services team's solution for air blower constraints has an incredible payback—in days or weeks. There's no reason any FCC should be air blower constrained during warmer temperatures since Aggreko has a practical, custom-engineered solution to this common problem. We deploy fast cooling expertise into the mix, cooling the inlet air to the MAB.
Chilling inlet air from around 105°F to 60°F pushes denser air into the regenerator, allowing for a more efficient coke burn-off and granting optimal catalytic activity in the reactor.
