Catalyst regeneration rates can suffer and reaction chemistry can change, driving up catalyst deactivation rates. Air and steam distributors are an integral part of the fluid catalytic cracking (FCC) process and are often overlooked. Ensuring a constant fluidized bed can greatly improve unit process performance, mechanical reliability and profitability.
In this article, originally published in Hydrocarbon Engineering, Blasch engineers discuss the number of different engineering strategies for dealing with abrasive wear, and how when it comes to material selection - the harder, the better. With Blasch ALTRONTM FCC air distributor nozzles and wear liners, plants can achieve:
