Explore our core product portfolio of certified chemical porcelain and engineered ceramics. Fabricated under stringent ASTM C515 and ISO 9001:2015 criteria to deliver superior voidage, wetting area, and structural integrity.
From elementary Raschig cylinders to fluid-dynamically optimized saddles, discover how next-generation ceramic mass transfer media are adapting to modern aggressive chemical processes.
Early cylindrical Raschig configurations presented substantial hydraulic resistance and dead zones within packed beds. Modern 3rd-generation packings like Cascade Mini Rings (CMR) and scalloped Super Intalox Saddles promote anisotropic bed orientation, reducing axial pressure drop (ΔP) by up to 38% while enhancing turbulent gas-liquid contact.
Modern process chemistry demands vitrified chemical porcelain matrices that eliminate micro-fissuring under cyclic thermal stress. Advances in slip casting, vacuum de-airing extrusion, and high-temperature sintering yield ceramic packings with water absorption ratings below 0.5% and chemical acid resistance exceeding 99.8% across ASTM C515 regimens.
With stringent global Net-Zero initiatives, ceramic packings are vital in Direct Air Capture (DAC) and amine-based Point-Source Carbon Capture plants. Where flue gases contain traces of SOx, NOx, and hydrochloric vapors that degrade fluoropolymers and stress-corrode 316L stainless steel, ceramic media provide decades of uninterrupted service.
Process engineers cannot afford bed settling, silica leaching, or premature crushing in high-throughput distillation columns. Below are the verified physical, mechanical, and chemical properties of Zhongtai ceramic tower packing.

Located in Pingxiang, Jiangxi Province—the globally acknowledged capital of industrial ceramics—Pingxiang Zhongtai Environmental Chemical Packing Co., Ltd. leverages world-class mineral access and automated kiln manufacturing to support major global capital projects.
Our proximity to pristine secondary kaolin reserves and high-purity feldspar deposits eliminates inter-provincial shipping disruptions. Batch chemistry is monitored by automated X-ray fluorescence (XRF) before wet milling, ensuring absolute consistency in raw feedstocks.
Our continuous roller-hearth and automated tunnel kilns use intelligent multi-zone thermal controllers (±3°C variation). This prevents localized thermal gradients during the vitrification phase, producing zero-flaw saddles with repeatable tensile and compression ratings.
Direct inland multimodal connections to Shanghai, Ningbo, and Shenzhen ports enable full-container-load (FCL) shipments within 7–14 days of order sign-off. High automated production capacities safeguard major project deadlines from unplanned delays.
Mass transfer packing fails when media cannot endure the dynamic equilibrium of corrosive liquids and volatile vapors. Review field deployments where our ceramic tower packings serve as the primary contact substrate.
In contact-process sulfuric plants (93%–98% H₂SO₄), exothermic gas-liquid reactions destroy polymers and high-nickel alloys. Ceramic Intalox saddles and partition rings are the industry standard for intermediate and final absorption towers (IAT/FAT).
Hot moisture-saturated chlorine gas (Cl₂) rapidly corrodes metallic packing through chloride-induced stress corrosion cracking (SCC). Vitrified ceramic Pall rings offer zero chemical uptake, keeping pressure drop stable across long maintenance intervals.
Treating high-sulfur flue gas streams from smelting and coal gasification requires packing with exceptional erosion-corrosion resistance. Ceramic media withstand acidic fly-ash slurry without micro-abrasion or surface thinning.
Volatile Organic Compound (VOC) abatement systems and thermal oxidizers demand high specific heat capacity and thermal cycling resistance. Our ceramic saddles and rings handle sudden temperature swings from 150°C to 1,000°C without spalling.
