Key Technical Specifications and Performance Characteristics
This packing is primarily composed of high-purity alumina ceramic, typically with an alumina content exceeding 90%, ensuring robust chemical resistance and thermal stability. The "350y" designation refers to its specific surface area (350 m²/m³) and a characteristic wave angle (y likely denotes a tailored angle for optimal fluid distribution, often around 125° or 150°). Structurally, it consists of thousands of parallel, corrugated ceramic sheets stacked in alternating directions, creating uniform flow channels. Key performance parameters include a porosity of 70-80%, mechanical strength over 60 MPa, and a maximum operating temperature of up to 1200°C. These features collectively result in low pressure drop (critical for energy efficiency) and high separation efficiency, reducing the number of theoretical stages needed in distillation.
FAQ:
Q1: What is the significance of the 350 m²/m³ specific surface area in 350y ceramic packing?
A1: The 350 m²/m³ specific surface area maximizes contact between vapor/liquid phases, accelerating mass transfer rates and enabling more efficient separation of components like hydrocarbons or solvents.
Q2: Can 350y ceramic corrugated packing withstand highly corrosive environments?
A2: Yes. Its alumina ceramic composition provides excellent resistance to acids, alkalis, and organic solvents, making it suitable for applications involving H₂SO₄, NaOH, or organic acids.
Q3: Which industries benefit most from using 350y ceramic packing?
A3: It is widely applied in petrochemical distillation (e.g., crude oil fractionation), fine chemical synthesis (e.g., pharmaceutical solvent recovery), gas processing (e.g., CO₂ absorption), and environmental engineering (e.g., wastewater treatment for volatile organic compounds).
