Industrial Filtration Solutions Pharmaceutical Oil & Gas
Oil & Gas Filtration Solutions — Manufacturer in India | Praimo Industrial Filters & Spares Manufacturing Company
In oil & gas, “almost clean” isn’t clean enough. Abrasive fines, wax, scale, emulsified water, and corrosive species push equipment to its limits—especially under temperature swings, pressure shocks, and ATEX-zoned operations. Praimo Industrial Filters & Spares Manufacturing Company designs and manufactures complete, code-compliant oil & gas filtration solutions—from cartridge and bag filter housings to duplex filters, automatic self-cleaning strainers, coalescers/separators, and vacuum oil purifiers—for upstream, midstream, and downstream duty. We size each system for flow, viscosity, and allowable ΔP, and we select metallurgy (SS316L, Duplex 2205, Super Duplex, Monel, Hastelloy) to meet NACE MR0175/ISO 15156, ASME Section VIII-1, PED/CE, and ATEX Zone 1/2—so plants hit product specs, protect rotating assets, and extend MTBR with predictable lifecycle cost.
Oil & Gas Filtration Applications & Typical Contaminants (Upstream • Midstream • Downstream)
Upstream — Drilling, Completion, and Produced Water Reliability
Cuttings fines, barite, sand, and corrosion products can overwhelm separation trains. Cartridge filter housings (10–40″) with absolute-rated pleated media protect completion brines, while basket strainers remove coarse solids ahead of pumps and desanders. For produced water, automatic backwash filters with wedge-wire internals keep flow stable with minimal operator intervention.
Where brine clarity is critical, pair a coarse prefilter (25–50 μm nominal) with 5–10 μm absolute cartridges. You’ll stabilize ΔP and extend media life without compromising clarity.
Midstream — Pipelines, Terminals, and LACT Integrity
Custody-transfer demands consistent ΔP and cleanliness. Duplex filters enable continuous duty—no shutdown during change-outs—ideal for pipelines, loading terminals, and condensate service. Y-type and basket strainers protect meters and control valves from rust and wax; fuel/condensate coalescers strip entrained water and haze before storage or shipment.
Downstream — Refinery Utilities and Product Polishing
Refineries depend on clean amine/glycol loops, polished fuels, and dependable water systems. Bag filter housings (Size #1/#2) and pleated cartridges extend run lengths on utility side streams; vacuum oil purifiers and varnish removal systems bring turbine and hydraulic oils back within target ISO 4406 codes and lower varnish potential.
1–200 μm solids, rust/scale, wax/asphaltenes, catalyst fines, emulsions, gels, dissolved varnish precursors.
Cartridge & Bag Filter Housings for Oil & Gas (SS316L, Duplex SS, FRP, ATEX Options)
Single & Multi-Cartridge Filter Housings (10–40")
Multi-round vessels (5, 7, 12, 18, 24, 36, 52 rounds) handle absolute ratings down to 1 μm for final polishing, dehydration pre-treatment, and lube/fuel protection. Options include vent/drain, DP ports or gauges/transmitters, swing-bolt or clamp closures, internal electropolish, and skid-mounted manifolds with isolation and bypass.
Bag Filter Housings (Size #1/#2) — High Dirt-Holding at Low ΔP
For slug loads and gels, bag filter housings deliver a low cost-per-kg of contaminant removed. Quick-open covers shorten change-outs; magnetic inserts capture ferromagnetic wear debris in lube and transmission lines.
1–200 μm solids, rust/scale, wax/asphaltenes, catalyst fines, emulsions, gels, dissolved varnish precursors.

Duplex Filters & Automatic Self-Cleaning Strainers (Crude, Produced Water, Utilities)
Duplex Filter Systems — True Continuous Duty
- Duplex filters (basket or cartridge) provide instant chamber changeover—zero downtime during media replacement—fitting pipeline stations, cooling water, loading racks, and fuel forwarding. Interlocked manifolds prevent cross-contamination and simplify operation.
Automatic Self-Cleaning Filters — Backwash, Scraper, Bernoulli
- For high-solids or variable load services, automatic self-cleaning strainers run with ΔP-triggered cleaning via PLC. Choose backwash, scraper, or Bernoulli mechanisms with wedge-wire or perforated media. Cleaning cycles can be isolated to avoid upsetting downstream units.
In produced water with sand slugs, set a conservative clean-cycle ΔP threshold (≈0.5–0.7 bar). You’ll reduce sudden flow dips and protect pump NPSH margins.

Coalescers, Separators & Vacuum Oil Purifiers (Lube, Fuel, Transformer, Phosphate Ester)
Fuel & Condensate Coalescers — Water and Haze Control
- Horizontal/vertical coalescers remove free water and haze in diesel/jet fuel and condensate prior to storage or custody transfer. A three-stage path (pre-filter → coalescer → separator) protects meters, burners, and downstream catalysts from water-related variability.
Vacuum Dehydration & Varnish Removal — Turbine and Hydraulic Oils
- Vacuum oil purifiers pull both free and dissolved water to low ppm targets. Resin-based varnish removal lowers varnish potential, minimizing servo valve sticking and bearing deposits. Expect measurable improvements in ISO 4406 cleanliness codes, varnish potential index, and operating temperatures.

Materials, Design Codes & Compliance (NACE MR0175/ISO 15156, ASME, PED, CE, ATEX)
Metallurgy Matched to Service
- For sour and chloride-rich environments, we tailor metallurgy: SS316L for general duty, Duplex 2205/Super Duplex for chlorides and stress corrosion, Monel for HF alkylation contexts, Hastelloy for severe acids. Elastomers and seals are selected for temperature, aromatic content, and H₂S exposure.
Design, Inspection & Testing Discipline
- Vessels conform to ASME Section VIII-1 (U-stamp on request) and PED/CE. Welding follows qualified WPS/PQR with traceable filler metals. Hydrostatic tests at 1.5× design pressure verify integrity; NDE and PMI are available by ITP. For hazardous areas, assemblies are prepared for ATEX Zone 1/2 with proper earthing and labeling.
Project Documentation You Can Approve Quickly
- You receive a complete MDR: MTCs, ITP, NDE reports, calibration sheets, FAT/SAT procedures, installation manuals, and recommended spares—to accelerate site approvals and audits.
Mixed-metallurgy fasteners are a common early-failure point in sour service. Specify NACE MR0175/ISO 15156 coverage for all wetted parts—including springs and bolts—to eliminate surprises during hydrotest.
Sizing & Selection Guide (Flow vs ΔP, Viscosity, Micron Rating, Dirt-Load)
Practical, Step-by-Step Selection
- Define fluid & state: hydrocarbon, produced water, amine/glycol, lube/fuel; record temperature (°C) and viscosity (cSt).
- Set the cleanliness target: by OEM requirement (e.g., ISO 4406 16/14/11) or process clarity.
- Choose media & rating: 1–5 μm absolute for final polish; 10–50 μm nominal for protection; pick bag vs cartridge based on dirt-load profile.
- Verify ΔP: apply viscosity-corrected curves and check worst-case cold start.
- Determine area/count: calculate cartridge or bag surface area using face velocity and dirt-holding capacity.
- Plan maintenance: define change-out ΔP (≈1.0–1.5 bar for cartridges; 0.7–1.0 bar for bags) and stock spares accordingly.
Rules That Protect Budgets
- Use the coarsest effective micron that still meets spec—longer cycles, fewer change-outs.
- Keep approach velocity modest to avoid erosion and re-entrainment in high-sand services.
- When downtime is expensive, specify duplex or self-cleaning—it’s often cheaper than extra manpower.
If startup viscosity exceeds design by >2×, simulate cold-start ΔP. Either oversize by one media grade or add a pre-strainer; it prevents nuisance trips during commissioning.

OEM-Compatible & Reusable Elements (Stainless Steel, Sintered, Resin-Bonded)
Reusable Stainless-Steel & Sintered Metal
Backwashable SS wire-mesh and sintered metal elements tolerate solvents, temperature cycles, and aggressive cleaning—ideal where disposal is restricted or where thermal shock is likely.
Disposable High-Efficiency Elements
Pleated PP/PES/PTFE deliver high capture efficiency for final polishing; wound or melt-blown provide gradient depth for variable loads; large-diameter high-flow cartridges keep ΔP low at high throughput. Resin-bonded designs maintain structure in aromatics and elevated temperatures.
In refinery solvent loops, resin-bonded cartridges outlast standard melt-blown—expect steadier ΔP and longer run length under heat and aromatics.

Case Results & Measurable Wins (ΔP, MTBR, OPEX)
Pipeline Lube System — Cleaner Oil, Cooler Bearings
Converting to duplex cartridge filtration with absolute 6 μm media improved ISO 4406 from 20/18/15 to 16/14/11. Bearings ran cooler, seals lasted longer, and unplanned outages declined.
Produced Water — Hands-Off Solids Control
Replacing manual baskets with automatic scraper strainers cut manual interventions by >70%, normalized ΔP during sand slugs, and reduced pump cavitation events.
Fuel Polishing — Haze Eliminated at the Rack
A three-stage coalescer train routinely achieved <15 ppm free water and eliminated haze complaints, protecting metering accuracy and custody-transfer quality.
Track ₹/kg contaminant removed, not ₹/element. That single KPI consistently selects the right media—and it’s how plant OPEX quietly trends down.
Installation, Commissioning & Maintenance (Best Practices for Oil & Gas Sites)
Mechanical & Piping
- Provide a full-bore bypass for maintenance in single-path services; specify duplex for truly critical lines.
- Fit DP gauges or transmitters with block/bleed for safe calibration.
- Add high-point vents and low-point drains for gas purging and clean change-outs.
- Verify flow direction, element count/length, and gasket compatibility before startup.
Operations & Safety
- Define and label change-out ΔP at the vessel.
- Stock spares (elements, gaskets, gauges) near point-of-use.
- For auto self-cleaning units, confirm instrument air/electrical, and test ΔP triggers before putting the line in service.
- Follow ATEX procedures where applicable; ensure proper earthing and bonding of skids.
A one-page commissioning checklist—strain the system, verify rotation/flow, leak test, and log baseline ΔP—solves 90% of the “mystery” issues that appear after handover.
FAQs — Oil & Gas Filtration
For crude side streams and pump protection, start at 25–50 μm nominal; for produced water polishing, use 10–25 μm nominal or 5–10 μm absolute depending on discharge or reinjection criteria.
If solids are moderate and predictable but zero downtime is essential, duplex is simple and robust. If solids vary widely or operator time is limited, automatic self-cleaning stabilizes ΔP and reduces manual handling.
In sour/H₂S service, specify NACE MR0175/ISO 15156 for all wetted components. In hazardous areas, ensure the assembly and peripherals are ATEX-ready with compliant earthing and marking.
Back-calculate from target face velocity and dirt-holding capacity. Provide flow (m³/hr), viscosity (cSt), temperature (°C), solids (ppm & μm), and allowable ΔP—and Praimo Industrial Filters & Spares Manufacturing Company will return a precise count and sizing sheet.
