Industry Overview

All-Metal Filtration for Processes That Destroy Polymer Media

Petrochemical and chemical processing plants often operate at temperature and pressure combinations that eliminate many conventional filter media options. A polymer cartridge rated to 90°C is rarely appropriate in a 350°C thermal cracker effluent line. A polypropylene housing rated to 4 bar is not the right choice for high-pressure hydroprocessing circuits.

Sintered 316L stainless steel and special alloy filter elements address all three petrochemical filtration failure modes: temperature, pressure, and chemical attack. For severely corrosive streams — concentrated HCl, mixed acids, or halogenated solvents — we supply Monel 400 and Hastelloy C-276 sintered elements on request.

Our high-temperature sintered filter elements have been deployed in FCC catalyst fines recovery, natural gas dedusting ahead of compressors, and polymer melt filtration — environments where unplanned downtime for filter replacement carries a cost that far exceeds the capital cost of switching to metal media. For in-reactor catalyst support and fixed bed applications, see our sintered porous tubes and catalyst support components.

For non-standard alloys or housing geometries, our custom OEM/ODM manufacturing covers everything from Monel and Hastelloy elements to drop-in replacements for your existing housings.

Applications

Demanding Applications Where Metal Filters Are Essential

High-Temperature Gas Dedusting

Sintered SS filter elements on process gas streams ahead of compressors and heat exchangers — removing catalyst fines, scale, and particulates at temperatures up to 400°C.

5–100 µm · ≤ 400°C · Wall-dependent

Catalyst Recovery

Fine-pore sintered elements retaining and recovering expensive catalysts — including precious metal catalysts — from process streams in hydroprocessing and petrochemical reactors.

0.5–5 µm · Consistent rated · High pressure

Corrosive Chemical Filtration

Monel 400 and Hastelloy C-276 sintered elements for filtration of concentrated HCl, mixed acids, and halogenated solvents — where standard SS 316L may not offer enough corrosion margin.

Monel / Hastelloy · Custom alloy

Polymer Melt Filtration

Sintered SS and pleated felt elements for high-viscosity polymer melt filtration in extrusion and compounding — high void volume, low pressure drop, rated for continuous high-temperature service.

3–150 µm · High viscosity · ≤ 400°C

Natural Gas Line Filtration

Inlet gas filtration ahead of metering, compression, and processing — removing pipeline scale, compressor lubricant carryover, and liquid slugs from gas transmission lines.

1–20 µm · Sour gas rated · NACE materials

Offshore & Subsea Applications

Titanium filter elements for offshore platform seawater injection, subsea chemical injection, and corrosive service where weight reduction and corrosion resistance are both priorities.

Ti Sintered Filter for Corrosive Media
Pure Titanium · Corrosion-Resistant

Ti Sintered Powder Filter Element

For corrosive chemical service where SS 316L is marginal. Titanium is often evaluated for HCl, H₂SO₄, oxidising media, and chloride-containing streams, subject to concentration, temperature, and pressure conditions.

Why FILTURE

What Petrochemical Plant Engineers Require

Rated to Process Extremes

Sintered SS elements are tested by us at the rated operating pressure before shipment — not just dimensionally inspected. 1.5× rated pressure hold for 10 minutes minimum. Test certificate included with every batch.

Non-Standard Alloys Quoted

For applications where SS 316L is inadequate — concentrated HCl, wet chlorine, mixed acid service — we source and sinter Monel 400, Hastelloy C-276, and Inconel 625. Alloy selection guided by our technical team based on your process chemistry.

Long-Term Supply Continuity

Replacing metal filter elements in petrochemical service typically happens on a 2–5 year cycle. We maintain design records for every custom element we have ever produced — enabling exact repeat orders years later without re-qualification.

What Petrochemical Customers Say

"

We used these elements in catalyst recovery service at elevated temperature with acidic carryover. Service life was noticeably better than our previous setup, and replacement planning became more predictable.

Process Engineer Petrochemical Refinery · South Korea
"

We tested four suppliers for a high-pressure filter duty at 18 MPa. FILTURE's elements passed the pressure cycling test without deformation. No other supplier's product did.
