Pingxiang Daier Ceramic Triple Y Ring – Acid Resistant Random Tower Packing for Chemical Absorption

1. Engineered for Extreme Corrosion – The Ceramic Triple Y Ring from Pingxiang Daier

In sulfuric acid drying towers, hot chloride gas scrubbers, and nitric acid absorbers, the packing material faces a dual threat: chemical attack and thermal shock. Metals pit, plastics soften, and inferior ceramics spall. Pingxiang Daier’s Ceramic Triple Y Ring (D-A-I-E-R brand) addresses this with a formulation that prioritizes acid resistance ≥99.8% and thermal stability up to 1100°C – not as a marketing claim, but as a verifiable batch‑to‑batch specification.

Manufactured in Pingxiang, Jiangxi, China, we source refractory clays and calcined alumina to achieve a dense, low‑porosity body (<1% apparent porosity) that resists penetration by aggressive media. The triple‑Y internal partition, unlike open rings, forces liquid breakup and re‑distribution at every contact point – a passive hydraulic effect that reduces channeling without increasing pressure drop disproportionately.

2. When to Choose the Triple Y Over Other Random Packings

This packing is not for hydrofluoric acid or strong alkalis above 80°C – a limitation we disclose transparently.

3. Real‑World Application Profile (Case‑Based)

Case A – Sulfuric Acid Drying Tower Retrofit
A Chinese copper smelter replaced ceramic saddles with Triple Y rings (size 50mm) in a 3.8m diameter drying tower. The result: outlet moisture dropped from 0.08 g/Nm³ to 0.05 g/Nm³ at the same gas velocity, while tower pressure drop decreased by 18% due to the more open structure. The rings have been in service for 32 months without visible corrosion or breakage.

Case B – Chlorinated VOC Scrubber
A chemical plant in Texas used 25mm Triple Y rings in a caustic‑followed‑by‑acid scrubber train. After 14 months, competitor rings showed weight loss >5%; DAIER’s rings, with acid resistance >99.8%, lost less than 0.3% – verified by independent lab testing.

4. Dimensional & Performance Data (by Size)

HETP values are indicative for air‑water systems; actual performance depends on physical properties and liquid/vapor rates.

5. Installation & Operational Considerations for Engineers

• Bed support: Use a support plate with openings ≤ 50% of the nominal ring size.

• Dumping: Pour gently from ≤1.5m height to avoid chipping; do not drop from high elevations.

• Liquid redistributor: For beds >3m, install a liquid collector‑redistributor every 3‑4m to prevent wall flow.

• Start‑up: Gradually bring up temperature (≤50°C/h) to avoid thermal shock.

• Maintenance: Inspect top layer annually; replace broken rings (>5% breakage triggers full re‑pack).

6. Material Assurance – Beyond the Data Sheet

Every batch from Pingxiang Daier is accompanied by:

• Chemical analysis (Al₂O₃, SiO₂, Fe₂O₃, K₂O, Na₂O)

• Acid solubility test (boiling H₂SO₄ for 6 hours, weight loss recorded)

• Crush strength (on individual rings, minimum 2000 N for 50mm)

• Thermal shock test (1000°C to water, 3 cycles without cracking)

We do not rely on generic certificates. Test reports are available per batch on request – a practice that differentiates us from traders who blend unsorted kiln outputs.

7. Industry Solution Mapping – By Process, Not by Product

8. Competitive Differentiation – What DAIER Does Not Do

• We do not use “high‑quality” as a vague term; we state Al₂O₃ ≥ 17% and acid loss ≤ 0.2%.

• We do not hide the fact that ceramic is brittle – we provide packing instructions to minimize breakage.

• We do not cherry‑pick test results; we provide full batch records.

This level of engineering transparency is why many European and North American EPC firms list Pingxiang Daier as an approved supplier for corrosive tower packings.

9. Complementary Products from Pingxiang Daier

While the Triple Y Ring is our core ceramic random packing, we also offer:

• Ceramic saddle rings (Intalox, Berl)

• Ceramic structured packing (corrugated plates)

• Ceramic ballast rings (for support layers)

• Tower internals (liquid distributors, support plates, gas inlets)

All manufactured under ISO 9001:2015 at our Pingxiang facility, with technical consultation provided by our Taiwan‑based engineering team.

10. How to Engage – Engineering First

We do not respond with price lists. Instead, we respond with:

• Preliminary hydraulic calculation (flooding % vs. F‑factor)

• Estimated HETP for your specific system (solvent, temperature, pressure)

• Material recommendation (standard vs. high‑alumina vs. low‑iron)

• Installation drawing for your column diameter

To start, simply share:

• Tower diameter, bed height

• Gas/liquid flow rates and densities

• Operating temperature and pressure

• Main chemical species present

Send these to our engineering desk via our official website (contact page) – no obligation, purely technical evaluation.
