Explore high-performance chemical tower packing and functional media manufactured in our Pingxiang manufacturing park under strict ISO & ASTM parameters.
Overcoming the structural limitations of standard Berl and standard Intalox saddles with corrugated, scalloped geometry.
Traditional random saddles often experience liquid nesting and channel segregation at elevated gas velocities. The Super Intalox Saddle geometry features scalloped ribs and perforated edges that disrupt laminar boundary layers, forcing continuous liquid film renewal across the entire packed volume without premature flooding.
By preventing parallel alignment (nesting) through enhanced dimensional curves and alternating edge bevels, our Super Intalox packings maintain bed voidages above 75% to 82%. This structural openness translates directly into a 20% to 35% lower pressure drop per theoretical stage compared to legacy ceramic Raschig rings.
Manufactured from premium kaolinitic clays, silica, and alumina blends fired in automated tunnel kilns above 1280°C, these saddles resist virtually all inorganic and organic acids (except hydrofluoric acid) across boiling operational regimes, maintaining absolute mechanical stability under thermal shock conditions.
| Nominal Size (mm / in) | Bulk Density (kg/m³) | Geometric Surface Area (m²/m³) | Void Fraction (ε %) | Packing Factor (m⁻¹) | Typical Industrial Service |
|---|---|---|---|---|---|
| 25 mm (1") | 680 – 720 | 255 | 74 – 76% | 195 | Acid Absorbers, Pilot Distillation, Fine Chemical Scrubbers |
| 38 mm (1.5") | 610 – 650 | 180 | 76 – 78% | 130 | Chlor-Alkali Drying Columns, SO₂ / SO₃ Strippers |
| 50 mm (2") | 540 – 580 | 135 | 78 – 81% | 85 | High-Volume Sulfuric Acid Plant Absorption Towers |
| 76 mm (3") | 460 – 500 | 95 | 82 – 85% | 52 | Flue Gas Desulfurization (FGD), Heavy Quench Towers |
How Pingxiang Zhongtai leverages two decades of infrastructure to provide global EPCs with unmatched scalability, raw material security, and rigorous production speeds.
Our facility in the West Section Hi-Tech Industry Park sits atop China's premier non-metallic mineral corridor. Direct access to high-purity kaolin deposits eliminates supply choke points and insulates international projects from upstream price volatility.
Utilizing digital temperature-regulated tunnel kilns up to 100+ meters in length, Zhongtai ensures that every single Super Intalox saddle achieves full vitrification, eliminating soft cores and minimizing friability during rapid tower loading.
Positioned near major transportation arteries with integrated multimodal logistics to Shanghai and Shenzhen ports, we reliably package products in customized heavy-duty seaworthy super-sacks or wooden crates within accelerated delivery schedules.
Demanding chemical engineers require more than marketing claims. We back our materials with international laboratory test reports, plant audits, and standardized test criteria.
Every lot of ceramic Super Intalox saddles complies with ASTM C515 (Standard Specification for Chemical Porcelain Tower Packings) and HG/T 3683.1 industrial criteria, guaranteeing minimum acid solubility loss (<0.5% in concentrated boiling sulfuric acid).
We routinely facilitate on-site batch sampling and pre-shipment inspections by independent verification bureaus (SGS, Bureau Veritas, TÜV Rheinland), validating piece crush strength, water absorption (<0.5%), and dimensional tolerances.
Streamlined logistics for multinational engineering contractors. We provide Certified Mill Test Certificates (MTC), Certificates of Origin (CO, Form E, Form A), fumigation certificates, and complete safety data sheets (MSDS/SDS) for seamless customs clearance.
From North American sulfur recovery units to Middle Eastern petrochemical scrubbers and European environmental remediation systems.
Main drying towers, intermediate absorption towers (IAT), and final absorption towers (FAT) where extreme exothermic acid contact rapidly degrades inferior packing materials.
Removing SO₂, HCl, and Cl₂ vapors from chemical effluent streams. The curved geometry prevents particulate entrapment and minimizes cleaning cycle shutdowns.
Serving as high-durability heat transfer media and top-bed hold-down layers in RTOs, resisting extreme cyclic thermal shifts between 200°C and 1100°C without spalling.
De-fluorination columns and high-concentration phosphoric acid concentration systems where conventional metallic alloys experience rapid localized pitting.
Navigating the next generation of chemical plant revamps, point-source decarbonization, and environmental performance requirements.
Large-scale amine absorption columns in direct air capture and flue gas decarbonization require gigantic tower footprints. Low-pressure drop random packings like Super Intalox saddles reduce overall blower parasitic electrical consumption, substantially improving project Net Present Value (NPV).
Older refineries and chemical facilities face immense pressure to increase throughput without constructing new vessels. Replacing standard ceramic rings with advanced Super Intalox shapes allows up to a 25% capacity increase within existing column shells.
Ongoing material R&D is delivering micro-textured surfaces that enhance surface wettability for non-aqueous solvents, driving lower mass transfer height equivalents (HETP) and reducing required overall bed depths.
