Key Structural and Material Advantages
The 250y structure, with its precise corrugation angle (typically 120°) and uniform spacing, ensures optimal gas-liquid contact, maximizing mass transfer efficiency. The specific surface area of 250y is tailored to balance between gas flow resistance and liquid hold-up, reducing energy consumption while enhancing separation precision. Made from high-purity alumina ceramics (Al₂O₃ content ≥90%), it exhibits exceptional chemical inertness, resisting corrosion from strong halogenated compounds like dichloromethane, chloroform, and chlorobenzene. Additionally, its high mechanical strength (flexural strength >35 MPa) and thermal shock resistance (up to 1000°C) ensure long-term stability in harsh industrial environments, minimizing maintenance needs.
Industrial Applications in Halogenated Compound Processing
In chemical synthesis, 250y ceramic structured packing is widely used in distillation columns and absorption towers for separating halogenated intermediates. For example, in pharmaceutical manufacturing, it facilitates the purification of halogenated solvents (e.g., 1,2-dichloroethane) used in drug synthesis, ensuring high-purity products with yields exceeding 99.9%. In fine chemical production, it plays a critical role in separating isomers of halogenated compounds, such as ortho- and para-chlorotoluene, which require strict separation accuracy. Moreover, in environmental protection, it is applied to absorb and degrade halogenated organic pollutants in industrial exhaust gases, reducing environmental discharge through efficient gas-liquid interaction. These applications highlight its versatility in handling diverse halogenated compound streams, from high-purity fine chemicals to industrial byproducts.
