Y350 corrugated structured packing is a high-performance internals for chemical separation, engineered to optimize mass transfer in distillation and absorption columns. Its core performance parameters, such as specific surface area, porosity, and pressure drop, directly influence separation efficiency and operational stability. This article details these critical metrics, product features, and industrial applications.

Performance Parameters Explained
The performance of Y350 structured packing hinges on three key parameters. First, its specific surface area (SSA) is approximately 350 m²/m³, balancing surface availability for molecular exchange with minimal flow resistance. This SSA ensures sufficient contact between gas and liquid phases, a cornerstone of efficient separation. Second, porosity, measured at around 95%, allows unobstructed fluid flow, reducing pressure drop across the packing—typically 0.5-1.2 kPa/m for common operating conditions. Lower pressure drop translates to reduced energy consumption, a critical advantage for large-scale industrial systems. Third, the packing’s rigid, 125°/60° alternating corrugation geometry minimizes channeling and promotes uniform liquid distribution, ensuring consistent separation results even under varying feed rates. Constructed from corrosion-resistant materials like 304 or 316L stainless steel, Y350 packing exhibits excellent durability, withstanding high temperatures and aggressive chemical environments common in petrochemical, pharmaceutical, and environmental treatment processes.
Common Questions About Y350 Structured Packing
Q1: What is the typical specific surface area of Y350 packing?
A1: Y350 corrugated structured packing has a specific surface area of approximately 350 m²/m³, optimized for efficient mass transfer in distillation columns.
Q2: How does Y350 packing improve separation efficiency compared to random packing?
A2: Its ordered corrugation structure reduces backmixing and enhances liquid redistribution, leading to a lower height equivalent to a theoretical plate (HETP) and higher separation efficiency than random packing.
Q3: Which industries widely use Y350 structured packing?
A3: It is commonly applied in petrochemical distillation (e.g., gasoline fractionation), pharmaceutical solvent recovery, and environmental gas treatment (e.g., CO2 absorption).
