Product Description

As a century-old classic among random packings, Ceramic Raschig Rings-crafted from high-alumina/acid-resistant porcelain-deliver unparalleled performance with their triple shield: 500°C heat resistance, 98% sulfuric acid defiance, and Mohs 7 hardness. They stand as the "ironclad defenders" in mass transfer equipment across chemical, environmental, and metallurgical sectors, irreplaceable where plastic or metal packings fail.
 

Application

1. Acid Mist Elimination Systems

1. Conc. H2SO4 Drying Towers: >99.5% capture efficiency (12+ years runtime in phosphate plant)
2. HCl Recovery Towers: 95%+ recovery (40% cost reduction vs. graphite in chlor-alkali plant)

2. High-Temp Flue Gas Combat

Scenario	Temp	Media	Service Life
Waste Incineration Quench	200ºC→60ºC	HCl+Dust+Dioxins	8+ years
Coke Oven Gas Desulfurization	55ºC	H2S+Tar+NH3	10 years
Aluminium Electrolysis Gas Purification	130ºC	HF+Al2O3 Dust	6+ years

3. Core Chemical Reaction Zones

1. Phosphoric Acid Concentration: Replaces 316L stainless steel, resists fluoride corrosion, 60% CAPEX reduction
2. Phosgene Absorption: Zero corrosion leakage in lethal media (key equipment in agrochemical plant)

4. Environmental Crusade Systems

1. Ammonia Stripping Towers: Tolerates alkaline wastewater (pH=12) shocks
2. VOCs Recovery Towers: Resists toluene/acetone solvent corrosion

Three Selection Principles

 

1. Anti-Breakage: Loading height ≤3m; use woven bag buffering
2. Thermal Shock Defense: Heating rate ≤30°C/h (steam tracing during emergency shutdowns)
3. Efficiency Boost: Pair with porous ceramic distributors for 40% mass transfer gain

Industrial Proof: In a mega coal-to-olefins plant, 100mm rings in a solids-containing desulfurizer delivered 22% lower pressure drop vs. structured packing-zero replacement in 6 years. Where heat, acid, and solids converge in hellish conditions, it remains the engineer's ultimate trump card.
