Company context
This company develops polymers and derivatives from petroleum. Certain manufacturing processes require in-line filtration of Polyisobutene (PIB) to remove all visible suspended particles before final packaging.
Filtration challenge
The manufacturer wanted to implement new filter cartridges meeting three main criteria:
- Be deliverable within less than 14 weeks per batch of 37 × 30″ filter cartridges.
- Match the exact dimensions of the existing ones to ensure compatibility with the current filter housings (2 filter housings with 37 cartridges each),
- Be made from a material capable of withstanding the harsh operating conditions of the production line (high pressure and temperature, chloride ion corrosion),
- Be easy to clean,
- Be deliverable within less than 14 weeks per batch of 37 × 30″ filter cartridges.
Pemflow filtration solution
To meet dimensional requirements and ensure perfect compatibility of the proposed filter cartridges with the 2 existing filter housings, we first worked from technical drawings.
To eliminate any risk of premature corrosion, we selected a cartridge made from woven Inconel® 600 fibres. It also offers full compatibility with all operating conditions and features a smooth outer surface suitable for cleaning procedures.
Finally, to reduce the delivery time from 14 to 5 weeks, Pemflow keeps a safety stock of the filter media used in the cartridge.
The ease of installation and removal of the cartridges using tapered end caps ensures good ergonomics at the workstation. Chemical resistance to operating conditions is also strong. Filtration performance is excellent: the filtered Polyisobutene (PIB) is clear, with no visible suspended particles, and fully meets the client’s product compliance requirements.
Customer support continues to further improve the system, particularly its mechanical strength, by considering an alternative to Inconel® 600. Options currently under review include an ALLOY® 59 solution (with a molybdenum content above 16%).
