550y ceramic corrugated structured packing is a specialized ceramic-based separation tool engineered for petrochemical plant operations. Its unique geometric design—characterized by precisely arranged corrugated channels—enables optimal mass transfer in distillation, absorption, and extraction processes, critical for refining crude oil, producing petrochemical intermediates, and purifying solvents. This packing type balances efficiency, durability, and chemical resistance, making it indispensable in modern petrochemical refineries.

Key Features and Product Specifications
Crafted from high-purity alumina or silica-alumina ceramics, 550y structured packing exhibits exceptional thermal stability, withstanding temperatures up to 1200°C, and excellent chemical inertness against acids, alkalis, and organic solvents—key traits for harsh petrochemical environments. Its "550y" designation refers to a specific geometric parameter, typically a surface area of 550 m²/m³ and a void fraction of 0.8-0.85, which minimizes pressure drop while maximizing contact between gas and liquid phases. The regular wave pattern (usually 120° or 90° angles) ensures uniform fluid distribution, reducing channeling and dead zones, thus boosting separation efficiency by 15-20% compared to traditional random packing. In petrochemical plants, it is widely used in fractionation towers for ethylene production, distillation columns for gasoline/diesel refining, and absorption towers for hydrogen sulfide removal, where reliability and long service life (10+ years) are essential.
FAQ: Commonly Asked Questions
Q1: What makes 550y ceramic packing suitable for petrochemical distillation towers?
A1: Its high surface area (550 m²/m³) and ordered structure enable efficient vapor-liquid contact, while chemical and thermal resistance ensures stable performance in corrosive, high-temperature petrochemical streams.
Q2: How does structured packing improve process economics compared to random packing?
A2: Reduced pressure drop lowers energy consumption, and higher separation efficiency shortens production cycles, leading to lower operational costs and increased throughput for petrochemical plants.
Q3: What maintenance is required for 550y ceramic structured packing?
A3: Minimal maintenance is needed—ceramic materials resist fouling, scaling, and corrosion, reducing cleaning frequency and extending the packing’s service life without compromising performance.
