Natural gas filters
Protection of regulators, meters, burners, turbines and compressors from dust, rust, sand, welding debris, water, condensate and oil aerosols.
Each stage removes a different contaminant
A mesh strainer stops coarse solids. A cartridge reduces fine particulate loading. A separator drains bulk liquid, while a coalescer combines aerosol droplets for removal. H₂S, mercury and moisture require a dedicated adsorption stage.
From pressure-reduction skids to turbine fuel gas
Washable, reusable element for PRS and GRU stations and cabinet regulators, upstream of meters and regulators.
Replaceable mesh, synthetic-fibre or cellulose element upstream of burners, valves and precision meters.
Inertial removal of coarse solids and liquid without a replaceable element, for distribution and compressor stations.
Cyclonic stage and filter element in one vessel for transmission pipelines and gas distribution stations.
Remove oil mist, water and condensate upstream of turbines, gas engines and CNG compressors.
Activated carbon, zeolite or ZnO beds for sulphur removal, mercury control and gas drying.
Gas supply stations and process consumers
Cyclone, separator or mesh strainer at the inlet, upstream of regulation and metering.
A 10–50 µm stage upstream of burners in cement, brick, ceramics, glass, metals and food processing.
1–5 µm fine filtration plus coalescing for turbines, gas engines and CNG stations.
Process data that define the design
- What to specify
- Diameter, operating and design pressure
- Design impact
- Vessel, flanges and wall thickness
A typical 5–10 kPa ΔP range is not universal. The allowable drop must be checked against the regulator, burner, turbine or compressor data and the full line calculation.
Pressure, connection and vessel material
These ranges help define the enquiry; final execution follows design pressure, process medium and project codes.
- Execution
- ≤ 0.005 MPa
- Typical duty
- GRU skids and boiler houses
Equipment and elements for existing lines
We supply and service equipment from leading European manufacturers and select compatible elements from drawings, dimensions and duty data. Selection may cover Pietro Fiorentini, Madas, Emerson/Tartarini, Honeywell/Elster, Parker, Pall, PECO and Jonell, without implying official partnership status.
Natural gas filtration questions
How is the required filtration rating determined?
From the protected equipment requirement and the actual contamination. Regulators usually need a coarse stage, burners 10–50 µm, and turbines fine particulate filtration plus aerosol removal.
When is a coalescer required?
When fine oil, water or condensate droplets pass through bulk separation and threaten valves, nozzles, compressors or turbines.
Can a cartridge be washed?
Only when the manufacturer explicitly permits regeneration of that medium. Mesh elements are commonly washable; fine-fibre and coalescing elements are generally replaced.
How do I know when to replace the element?
By differential pressure reaching its limit, loss of capacity or the maintenance schedule. A differential indicator or transmitter provides the signal.
What documents are needed for selection?
Line diagram, DN/PN, flow, temperature, gas and contaminant composition, allowable ΔP, material requirements, hazardous-area data and the protected equipment specification.
Can you supply elements for an existing housing?
Yes, after model identification or element measurement. A reliable equivalent requires dimensions, seal arrangement, media, rating, flow and duty conditions.
