Pingxiang Daier Ceramic Butterfly TY Ring Random Packing for High-Temperature Corrosive Service

Engineering Challenge: Packed Tower Performance Under Extreme Conditions

In chemical processing, metallurgical operations, coal gasification, and oxygen production, process engineers routinely face a dual constraint: tower internals must withstand temperatures exceeding 300°C while resisting aggressive mineral acids—sulfuric, nitric, hydrochloric, and others. Under these conditions, metal packing suffers pitting and uniform corrosion; plastic packing softens, deforms, and loses structural integrity.

Ceramic materials become the only viable engineering option.

The Ceramic Butterfly TY Ring (also referred to as Ty-Pak) is a random packing geometry specifically engineered for these extreme service conditions.

The DAIER Solution: Geometry + Material

Butterfly Profile Engineering

The butterfly-shaped profile creates a self-aligning, interlocking structure when randomly dumped into a tower bed. Unlike conventional rings that settle and compact over time, the butterfly geometry maintains consistent void distribution throughout the service life. This prevents two common failure mechanisms in packed beds:

• Channeling – preferential gas/liquid flow paths that reduce mass transfer efficiency

• Settling – gradual compaction that increases pressure drop and reduces throughput

The design enables faster loading and provides approximately 20% lower pressure drop compared to 1-inch ceramic saddles under equivalent operating conditions.

Material: Chemical Porcelain Composition

Pingxiang D-A-I-E-R manufactures Ceramic Butterfly TY Rings from high-quality solid-pressed silicate porcelain with alumina content (Al₂O₃) in the range of 17-23%. The material specification delivers:

Chemical Resistance Note: The material resists all inorganic acids, organic acids, and organic solvents with the sole exception of hydrofluoric acid (HF).

Performance Verification: By the Numbers

• Pressure Drop: 20% lower than 1-inch saddles—translates to reduced blower/compressor energy consumption

• Thermal Stability: Service temperature up to 1100°C for sustained high-temperature operation

• Chemical Durability: Acid resistance > 99.6%, compatible with sulfuric acid drying and SO₃ absorption towers

• Consistent Performance: Butterfly geometry prevents channeling and settling, maintaining specified mass transfer efficiency over time

• Low Moisture Absorption: <0.5% ensures structural integrity in wet/dry cycling

Custom dimensions are available upon request with engineering drawing approval.

Application Scenarios (Industry Solutions)

The Ceramic Butterfly TY Ring is specified for the following tower types across multiple industries:

Installation Considerations

1. Bed Support: TY Rings require a suitable support plate or grid at the bottom of the packed bed. The support must accommodate the ring geometry while allowing gas and liquid passage.

2. Dumping Method: Rings should be dumped uniformly across the tower cross-section to minimize size segregation and achieve consistent bed density.

3. Bed Height: Maximum recommended bed height per section depends on tower diameter and operating pressure. Contact D-A-I-E-R engineering for sectioning recommendations.

4. Liquid Distribution: For towers above 1.5 meters diameter, a liquid distributor is recommended above the packed bed to ensure uniform wetting.
