Fluid Catalytic Cracking / Catalyst Management

FCC Slurry Oil Filtration & Catalyst Fines Removal

Fluid catalytic cracking (FCC) units are a major application area for specialist refinery filtration. Fine catalyst particles can become entrained in refinery process liquids and gases, creating demanding separation requirements.

Slurry Oil / Decant Oil Filtration

FCC slurry oil may contain fine catalyst particles that need to be controlled or removed for subsequent processing, equipment protection or product quality.

Depending on the duty, Filtra can review cleanable metallic filtration elements, filter candles, specialised media, pressure-rated vessels and engineered filtration packages.

Backwashing or other cleaning arrangements can be evaluated where technically appropriate.

Catalyst Fines & Replacement Elements

Catalyst handling and associated process equipment may require specialist filter media, filter bags, metallic candles, cartridge elements or replacement internals.

Filtra has practical supply experience with substantial quantities of specialist aramid filter bags for catalyst-related industrial applications.

Media selection is always based on the actual liquid or gas duty, chemistry, temperature and mechanical requirements.

Offshore Platforms / Marine Water Systems

Offshore Reverse Osmosis, SWRO Membranes & RO Pretreatment Filtration

Offshore platforms and marine installations may require desalinated water for domestic, utility and selected industrial uses. Reliable reverse osmosis operation depends on both suitable membrane elements and effective upstream pretreatment.

From Seawater Intake to Reverse Osmosis Membrane

Filtra supplies filtration components for suitable seawater reverse osmosis (SWRO) and industrial RO systems. Depending on the installation, the pretreatment train can include:

1. Intake Protection Coarse screening and filtration to reduce larger suspended material.
2. Pretreatment Suitable media, high-flow and staged particulate filtration.
3. Cartridge Guard Filters Depth or pleated cartridges to protect downstream RO membranes.
4. RO Membranes SWRO or other RO elements selected for salinity, flow and permeate quality.

RO Pretreatment & Membrane Protection

Prefiltration can reduce suspended particles and help manage fouling risks before the RO stage.

Options include polypropylene depth cartridges, pleated cartridges, high-flow elements and matching cartridge housings.

Seawater & Industrial RO Membranes

We also supply the RO membrane elements themselves, including seawater membranes for high-salinity feeds and industrial membranes for suitable water applications.

Selection considers feed salinity, pretreatment quality, required permeate flow, operating pressure, membrane compatibility and system recovery.

RO pretreatment requirements depend on source-water quality, the membrane manufacturer's limits, suspended-solids loading, fouling tendency and the existing treatment system. Individual filter cartridges do not replace a complete pretreatment assessment.

Flue Gas / Wet Scrubbing / Emissions

FCC Flue Gas Filtration, Catalyst Dust Collection & Scrubber Separation

Refinery and petrochemical exhaust streams may contain catalyst fines, entrained particles and liquid droplets. Several filtration and separation technologies can be involved, depending on temperature, gas composition and emission-control objectives.

01

FCC Regenerator Flue Gas

Specialist high-temperature gas filtration systems can be evaluated for the removal of fine catalyst particles from suitable FCC regenerator flue gas streams.

Potential technologies include engineered metallic filter elements and specialised high-temperature filtration packages.

02

Catalyst Hopper Vent Filters

Catalyst loading, storage and unloading operations can generate fine dust. Suitable vent filters, filter bags, cartridge elements and dust-collection arrangements help control particulate escape and protect connected equipment.

03

Wet Gas Scrubbers & Demisters

Wet scrubbing and gas-cleaning installations may use mist eliminators, vane-type droplet separators, demister elements and liquid-filtration stages.

These components address specific entrainment and droplet-removal duties within the scrubber process.

Industrial Filter Bags & Aramid Media

Aramid (Nomex-type) filter bags can be considered for selected catalyst handling, dust collection and other elevated-temperature duties.

Exact bag design, filtration principle, temperature suitability, chemical compatibility and cleaning method must be confirmed for every installation.

High-Temperature Metallic Filters

Very hot or aggressive process-gas applications may require metallic filter candles or other specialist high-temperature media instead of conventional textile filter bags.

Engineered systems can be assessed against the actual gas composition, operating temperature, pressure, catalyst loading and project acceptance requirements.

Flue gas particle filtration, wet gas scrubbing, droplet separation and gaseous-pollutant removal are different processes. An individual filter is not necessarily a complete emissions-control system. Performance targets, technology selection and any required licensor approvals must be confirmed for each project.

Frequently Asked Questions

Oil & Gas Filtration FAQ

What is FCC slurry oil filtration?

FCC slurry oil filtration removes fine catalyst particles and other suspended solids from suitable refinery hydrocarbon streams. Depending on process temperature, pressure, viscosity and solids loading, the equipment may use specialised metallic filter elements and engineered vessels.

Can Filtra supply filters for FCC catalyst fines?

Filtra can review metallic filter elements, replacement filter media, specialist filter bags and engineered equipment for suitable catalyst filtration duties. FCC slurry oil, catalyst handling and regenerator flue gas are different applications and require separate equipment selection.

Can you supply flue gas and wet scrubber filtration solutions?

We can evaluate suitable high-temperature particulate filtration, catalyst dust collection, mist eliminators and droplet-separation components. Complete systems, emissions performance and any licensor or regulatory acceptance depend on project-specific qualification and supply scope.

Do you supply offshore RO prefilters and seawater RO membranes?
