The Engineering Challenge: Mechanical Stability in Deep Packed Beds
Moving Beyond Surface Area Alone
In large-scale chemical process systems, particularly in high-load Gas Scrubbing, Seawater Desulfurization, and heavy-duty VOC Treatment towers, Tower Internals face extreme mechanical stress. The weight of deep packed beds can cause conventional random packing to deform, crush, or interlock. This deformation leads to channeling, increased Pressure Drop, and a sharp decline in Distillation Efficiency.
Process Optimization requires a packing media that not only provides high surface area for Mass Transfer Solutions but also maintains structural integrity under load.
Solution Logic: The Crown Type Geometric Advantage
Multi-Point Contact and Structural Resilience
The DAIER Chemical Packing Kostar Garland (Crown Type Plastic Teller Rosette Ring) addresses this challenge through its distinct crown-type architecture. Unlike standard rosette rings, its structural design provides:
Superior Crush Strength: The crown geometry distributes compressive loads across multiple contact points, preventing collapse in deep beds.
Multi-Point Gas-Liquid Contact: The structure forces gas and liquid to continuously change direction, promoting surface renewal without creating excessive gas resistance.
High Void Ratio (>92%): Maintains a low Pressure Drop profile, reducing fan energy consumption in large scrubbing systems.
This makes the Kostar Garland an engineering choice for high-load applications where structural failure is unacceptable.
The DAIER Standard: Mandatory Material Integrity
The SS316L Molybdenum Constraint for High-Stress Applications
In corrosive and high-temperature chemical process systems, the structural integrity of the entire tower depends on the material quality of every component. Whether using Support Plates, Support Grids, or Liquid Distributors, material degradation leads to catastrophic system failure.
The DAIER Standard enforces a rigid material baseline. When SS316L stainless steel is selected for any metallic Tower Internal Engineering component, it must have a Mo (Molybdenum) content ≥ 2.0%. This mandatory requirement is the only reliable defense against chloride pitting and stress corrosion cracking. Non-standard SS316L (often 1.6%-1.8% Mo) is strictly rejected.
DAIER Material Specification Baseline:
Plastic Media: Virgin PP, PE, PVDF, PTFE (No recycled content).
Metallic Internals (SS316L): Mo (Molybdenum) content ≥ 2.0% (Mandatory PMI verification upon delivery).
Industry Applications & Diagnostic Framework
Targeted Solutions for Complex Operating Conditions
Pingxiang Daier Separation Tech works with plant engineers to apply Kostar Garland (Crown Type) packing in challenging environments:
Symptom: Packing deformation and increased Pressure Drop in deep beds.
Diagnostic: High mechanical load on lower packing layers.
Corrective Action: Replace conventional packing with Kostar Garland (Crown Type) to utilize its superior crush strength and structural resilience.
Symptom: Inefficient gas scrubbing in high-dust environments.
Diagnostic: Channeling and stagnant zones due to interlocking.
Corrective Action: Utilize the multi-point contact geometry to enhance liquid distribution and prevent solid accumulation.
Symptom: Corrosion failure in Seawater Desulfurization or HCl Scrubbers.
Diagnostic: Material mismatch or substandard Mo content in SS316L.
Corrective Action: Enforce the DAIER Standard (Mo ≥ 2.0%) for all metallic internals to ensure long-term reliability.
