(5) FLUID CATALYTIC CRACKING UNI T (FCCU) is a process unit in which petroleum derivative feedstoc k is charged and fractured into smaller molecules in the presence of a catalyst; or reacts with a contact material to improve feedstock quality for additional processing; and the catalyst or contact material is rege nerated by burning off coke and other deposits. The unit includes, but is not limited to, the riser, reactor, regenerator, air blowers, spent catal yst, and all equipment for controlling air pollutant emissions and recovering heat. (6) FLUID CATALYTIC CRACKING UNIT REGENERATOR is the portion of the fluid catalytic cracki ng unit in which coke burn-off andRule 1105.1 (Cont.) (Adopted November 7, 2003)

(9) SHUT-DOWN is a period which begi ns when fresh feed is pulled from
the FCCU reactor and ends when the main blower for catalyst
recirculation is shutdown. (10) START-UP is a period not to exceed one hundred twenty (120) hours which begins with the startup of the main blower for introduction of catalyst and ends when fresh feed is introduced to the FCCU reactor and the process reaches steady state
