Pressure Drop Performance

Below is the air-water pressure drop curve (D/d = 20):


The pressure drop data can help engineers evaluate operating targets, throughput requirements, and packed-bed performance for the intended tower design. It also provides a useful reference when comparing expected vapor and liquid rates against pressure drop limits.

Applications

  • Large-column distillation systems

  • High-capacity absorption towers

  • Stripping/venting operations, including steam and vacuum

  • Quench and direct-contact cooling towers

  • Gas cleaning and scrubbing, including acid gases, VOCs, and CO₂

  • High-temperature, high-corrosion service environments

  • Wastewater or brine contact towers

  • Gas-liquid separation in petrochemical and refining operations

PDS-MPALL-50 is suitable for applications that require durable metal random packing, efficient hydraulic performance, and reliable operation across a wide range of industrial processes. Its 50 mm size is especially useful where larger columns need capacity, flow stability, and practical pressure drop control.

Why Choose 50 mm Pall Ring Packing?

The 50 mm pall ring is commonly selected for larger columns where process requirements prioritize capacity and stable packed-bed operation. Its size makes it suitable for applications handling higher vapor and liquid flow rates while maintaining effective gas-liquid contact.

Typical Process Considerations

When evaluating metal pall ring packing, consider tower diameter, vapor and liquid rates, operating pressure, packing depth, material compatibility, and process objectives. Reviewing these factors helps ensure the selected packing is appropriate for the application and aligned with operating requirements.

Selecting the Right Material

Material selection should be based on operating temperature, corrosion requirements, process chemistry, and equipment design. PDS offers multiple material options to help match the packing to specific operating conditions, including services where strength, temperature resistance, or corrosion resistance are important.
