Case Study: 60-Inch High Flow Filter Cartridges for Palm Oil Refining in Southeast Asia

Industry: Palm Oil Refining & Edible Oil Processing
Region: Indonesia / Southeast Asia
Application: Refined Palm Oil (RBDPO) Filtration
Product: PULLNER 60" High Flow Pleated Filter Cartridge
Filter Media: High-Temperature PET (Proposed)
Filtration Solution: Customized High-Capacity Filtration

1. Customer Background

A large palm oil refinery in Southeast Asia operates continuous production lines for refined palm oil (RBDPO) and palm olein, supplying edible oil manufacturers and downstream processing facilities.

With large daily processing volumes, the refinery requires a reliable filtration system to remove residual particles and filter aid before oil transfer and storage.

Maintaining stable flow rates while minimizing production interruptions is particularly important for its high-capacity refining operations.

2. Customer Challenges

The refinery's conventional filtration setup presented several operational challenges:

• Frequent Filter Replacement: High particulate loading caused premature clogging, increasing maintenance frequency.

• Increasing Pressure Drop: Particle accumulation restricted oil flow and affected filtration efficiency.

• Temperature Requirements: Heated palm oil processing required filter materials suitable for elevated operating temperatures.

• High Operating Costs: Frequent cartridge changeouts increased consumable costs, labor requirements, and production interruptions.

The customer needed a higher-capacity filtration solution that could maintain stable performance while reducing maintenance requirements.

3. PULLNER's Proposed Solution

PULLNER developed a proposed filtration approach based on a 60-inch extra-long high flow pleated filter cartridge, with high-temperature PET media as a candidate material.

Compared with conventional shorter cartridges of similar diameter and construction, the 60-inch design provides additional filtration area within each element.

The solution focuses on three critical engineering requirements:

High-Capacity Filtration: The extended pleated structure increases available filtration area, supporting high-volume oil processing.

Structural Stability: Reinforced support options help maintain pleat geometry and reduce deformation risks under specified differential pressure.

Process Compatibility: Filtration media, sealing materials, and cartridge construction are selected according to oil temperature, viscosity, and operating conditions.

The cartridge dimensions and end connections can also be customized to match existing filtration housings.

4. Solution Development Process

1. Process Evaluation

   Review the customer's oil type, processing temperature, flow rate, operating pressure, existing cartridge specifications, and filtration requirements.

2. Media & Structural Selection

   Evaluate suitable high-temperature filtration media and develop a 60-inch pleated structure with appropriate support components.

3. Cartridge Compatibility

   Confirm overall length, outside diameter, end connection, sealing arrangement, and installation dimensions to ensure compatibility with the existing housing.

4. Performance Verification

   Evaluate filtration efficiency, clean pressure drop, flow capacity, structural integrity, and operating temperature suitability before production-scale implementation.

5. Production & Technical Support

   Following successful qualification, supply customized cartridges and provide technical guidance for installation, filtration monitoring, and maintenance.

5. Expected Results & Customer Benefits

The proposed 60-inch high flow filtration solution is intended to deliver the following operational improvements:

• Longer Filtration Service Intervals: Additional filtration area may reduce premature clogging and extend cartridge replacement intervals.

• Improved Flow Stability: Optimized pleat geometry and filtration area help control pressure drop during oil processing.

• Reduced Maintenance Workload: Higher-capacity elements may reduce the frequency of shutdowns for cartridge replacement.

• Lower Operating Costs: Fewer changeouts and potentially lower cartridge consumption can reduce long-term filtration expenses.

• Improved Equipment Compatibility: Customized dimensions allow integration into suitable existing filter housings without major modifications.

Actual improvements depend on operating conditions and must be confirmed through onsite trials.

6. Project Value

This application demonstrates how extra-long high flow cartridge engineering can address the specific filtration challenges of large-scale palm oil refining.

PULLNER offers customized 40-inch and 60-inch high flow filter cartridges for palm oil refining, edible oil production, and oleochemical processing.
