Crude Distillation Unit
1. Neutralizing Amine
Problem : Wasted chemical and possible corrosion on overhead piping caused by ineffective neutralizer injection.
Best practice : Use spray injectors designed to use steam as the atomizing fluid. This is preferable to feeding the neutralizer and steam through a quill. A steam atomized retractable injector ensures none of the neutralizer remains in a liquid state and provides more effective HCl neutralization.
2. Filming Corrosion Inhibitor
Problem : Creating a protective film barrier on the inside of the overhead line.
Best practice : Use WhirlJet Hollow cone spray nozzles spraying at low flow rates and operating at lower pressures to maximize drop size and filming effectiveness. The hollow cone spray pattern effectively applies the filmer to pipe wall.
3. Water Wash
Problem : Understanding how to effectively inject wash water in most efficient placement to dilute acid that has formed in the liquid phase and dissolve salt deposits.
Best practice : Use spray injectors instead of quills to minimize the risk of excess free water that may not interact properly with the vapor stream and cause erosion and other corrosion issues. Instead of using flow rate and pressure drop to determine injection points, use CFD to validate performance prior to finalizing injector design.
4. Fin Fan Water Wash
Problem : Poor wash water distribution and pooling on the floor of the header box.
Best practice : Position the spray nozzles inside the header box or install individual spray nozzles at pre-determined locations using clean-out plugs. Use CFD to validate performance before beginning injector design. Spray injector performance will vary greatly depending on gas flow rate and velocity. CFD can determine optimal spray nozzle placement.
5. Overhead Water Wash
Problem : Corrosion and salt in the overhead line and downstream equipment.
Best practice : Continuous wash water injection to prevent or remove corrosive build-up. Injectors equipped with WhirlJet hollow cone and FullJet full cone spray nozzles are widely used. The nozzles produce small- to medium-sized drops and uniform coverage. Also, use CFD to determine the optimal dispersion, coverage and injector placement for corrosion prevention.
6. VGO Wash Bed Spray Header
Problem : Prevent dry zones in the wash bed that produce coke formation and result in higher pressure drops in the column.
Best practice : Maximum Free Passage (MFP) FullJet full cone spray nozzles with wide spray angles maximize coverage to ensure uniform wetting. Large flow passages prevent nozzle clogging and reduce maintenance downtime.
Fluid Catalytic Cracking Unit
1. Fresh Feed
Problem : Maximize yield when injecting feed oil.
Best practice : Leading providers of FCCU riser technology supply proprietary feed injection systems with nozzles designed specifically for superior feed stock injection and extended wear life. These systems deliver the optimal drop size and spray distribution to increase cracking efficiency and yield.
2. Bio-Oil Injection
Problem : Inconsistent performance and reduced yield caused by nozzle wear.
Best practice : Use injectors that allow adjustment of feed rates, prevent feed polymerization and feature specially-designed wear-resistant nozzles.
3. Torch Oil
Problem : Safety issues such as CO2 build-up, mechanical issues in the regenerator during start-up and feed outage conditions caused by incomplete torch oil combustion.
Best practice : Use OptiMax injectors with patented technology for thorough mixing of the oil and steam. The injector produces uniformly sized small drops and consistent spray coverage to ensure complete combustion.
4. Main Fractionator Water Wash
Problem : Corrosion and salt in the overhead line and downstream equipment.
Best practice : Continuous wash water injection to prevent or remove corrosive build-up. Injectors with WhirlJet hollow cone and FullJet full cone spray nozzles are widely used. The nozzles produce small- to medium-sized drops and uniform coverage. Also, use CFD to determine the optimal dispersion, coverage and injector placement for corrosion prevention.
5. Emergency Quench
Problem : Quick and efficient cooling during upset conditions.
Best practice : Use injectors specially-designed for use with steam for quick cooling without wetting and damage to refractory-lined ducts. FloMax S spray injectors atomize water with steam and produce small drops that evaporate quickly and completely.
6. Slurry Recycle
Problem : Process disruption caused by equipment wear.
Best practice : Use high-flow steam atomized injectors, constructed of special alloys that resist wear caused by slurry abrasiveness. OptiMax injectors are designed for durability for efficient, continuous recycling.
7. Regenerator Shell Cooling
Problem : Hot spots that damage metal refractory shells.
Best practice : Use strategically-placed steam nozzles that provide rapid cooling. FloMax S nozzles use steam to atomize the water and produce consistently-sized small drops that provide quick cooling without wetting.
Coker
1. Quench Sprays
Problem : Slow the cracking reaction while preventing coke formation in the overhead line.
Best practice : Use Maximum Free Passage (MFP) FullJet full cone spray nozzles to inject coker gas oil into the drum outlet tee to quench and slow the cracking reaction. The nozzles are available with a wide range of spray angles to ensure a thin liquid film is maintained on the walls. Open flow passages resist plugging and provide longer service life before maintenance is required.
2. Defoaming
Problem : Foam elimination
Best practice : Maximum Free Passage (MFP) FullJet full cone spray nozzles feature a patented vane design that provides the largest free passage of maximum free passage nozzles to minimize clogging with uniform spray distribution. MFP FullJet nozzles provide excellent coverage at lower operating pressures.
3. Overhead Water Wash
Problem : Dissolve salt deposits in the overhead vapor line.
Best practice : Use built-to-order spray injectors designed for the operating conditions of the overhead vapor line to ensure optimal performance. Instead of using flow rate and pressure drop, use CFD to determine the ideal droplet size, coverage and location of injection points to maintain at least 25% free water.
4. Wash Oil
Problem : Wash and cool hot vapors entering the fractionator from coke drums and eliminate wash oil carryover.
Best practice : Maximum Free Passage (MFP) FullJet full cone spray nozzles effectively knock-out coke fines without clogging. The uniform spray pattern, consisting of large droplets, ensure quick and effective gas scrubbing and cooling.
Hydrotreater
1. Water Wash
Problem : Inadequate chloride scrubbing, wall wetting and maldistribution of the wash water through the piping system and REAC inlets.
Best practice : Use FloMax H two-fluid spray nozzles that use a slipstream of makeup hydrogen as the secondary fluid instead of conventional nozzles or spray quills. FloMax H nozzles maximize the surface area of the injected water and enable better contact with the chlorides and more uniform distribution of the wash water.
3 options for water wash
Quill
Quills used for water wash in hydroprocessing units typically have rectangular orifices that don't form discrete droplets. This results in minimal surface area for chlorisde scrubbing. In addition, the wash water isn't distributed uniformly and salt downstream of the injection point may not be dissolved. In some cases, this maldistribution of wash water may encourage salt formation.
Hydraulic Spray Nozzle
Full cone and hollow cone spray nozzles form discrete droplets. However, the droplets are too large to navigate the tee and bends in piping systems installed prior to the introduction of REACs. In addition, large droplets tend to form a water film in the piping system and are susceptible to maldistribution and reduced salt dissolution.
FloMax H
Two-fluid FloMax H spray nozzles have been engineered to optimize chloride scrubbing in water wash systems in hydroprocessing units. A slipstream of makeup hydrogen is used for atomization. The nozzle produces smaller droplets that saturate more of the vapor while maintaining 20 to 25% free water. The result is more uniform distribution of the droplets for chloride scrubbing in the piping, REAC inlets and exchanger tubes.
