XI Catalytic Cracking Complex Turnaround
It is turnaround of Catalytic Cracking Complex
Includes following plants: FCC, Vacuum, Merox, Gas Recovery, Utilities, CO Boiler, Salt Water Facilities
Organization includes 20 zones, such as:
Repair of CO Boiler
Replacements on reactor
Repair of rotating equipment
Repair of fractionating column
Repair of vacuum furnace
XI Catalytic Cracking Complex Turnaround
Replacement of FV4 reactor cyclone with two cyclones
Replacement of the stripper, adding 1 more plate.
XI Catalytic Cracking Complex Turnaround
CYCLONE:
Bad mechanical condition: Heavy damage on anti erosion protection of the cyclone
Efficiency lost
Accumulation of catalyzer on the bottom of fraction column
Need of bigger cyclone for present operation conditions
XI Catalytic Cracking Complex Turnaround
STRIPPER:
Bad mechanical condition of Baffles and stripper plates.
Damage of anti-erosion protection of Baffles.
Mechanical failure of steam distributor.
Low efficiency on stripping of hydrocarbon gases, due to higher load of FCC unit.
XI Catalytic Cracking Complex Turnaround
To improve the catalyst separation of hydrocarbon gases from the reactor, by saving catalyst, avoiding contamination of the fraction system and to process higher load of FCC unit.
Minimize dragging hydrocarbons to the regenerator.
To improve the thermal balance.
To reduce loss of hydrocarbons.
Overcome mechanical problems.
Increase operational reliability and flexibility

There are 92 joints to weld, distributed as follows:
47 during previous works. 45 during replacement.
Welding type Electrode
Alloy steel SMAW (Arc welding) E8018-B2
GTAW (TIG) ER80S-B2
Carbon steel SMAW (Arc welding) E7018
Clad (Inox) GMAW (MIG) OK.AUTROD-1679
Hex mesh and S-bar SMAW (Arc welding) E410 Ni-Mo
Electrodes required:
XI Catalytic Cracking Complex Turnaround
Materials to weld are Chrome Molybdenum alloys (1 Cr, Mo).
ASTM-387 GR.11
ASTM-335 GR. P11
ASTM-234 GR. WP11
Welding these materials is rather difficult due to Chrome content. Petroperus welders have to be trained in this welding type in order to get required skill.
Replacement is done according to following technical standards:
API 31.3 for pipes in petroleum refineries
ASME Secc. VIII for pressure vessels
UOP Standards
