Material Properties and Structural Design
This packing is crafted from high-purity alumina ceramics, boasting exceptional chemical inertness, high temperature resistance (up to 1200°C), and mechanical strength—critical for withstanding harsh refining conditions. The "100y" designation refers to its specific surface area, approximately 100 m²/m³, achieved through a precisely engineered grid-like structure with uniform, narrow channels. This geometry ensures optimal fluid distribution, minimizes channeling, and maximizes mass transfer efficiency, vital for separating ethylene, propylene, and other olefins from impurities such as paraffins, aromatics, and moisture. Precision manufacturing guarantees consistent packing density, reducing pressure drop and enhancing operational stability, making it a reliable choice for both new installations and upgrades.
Performance Benefits and Industrial Applications
100y ceramic structured packing delivers tangible advantages in olefin purification, including extended service life (10+ years with proper maintenance), reduced energy consumption due to lower pressure drop, and superior separation performance compared to traditional random packings. In practice, it is widely used in catalytic crackers, fractionation columns, and purification towers across major petrochemical plants. For example, in ethylene purification units, it effectively removes trace CO2 and H2S, ensuring product purity meets industry standards (e.g., 99.99% ethylene). Its resistance to corrosive process streams and thermal cycling further minimizes downtime, lowering overall operational costs.
FAQ:
Q1: What does "100y" signify in 100y ceramic structured packing?
A1: "100y" denotes the specific surface area, approximately 100 m²/m³, which optimizes mass transfer by increasing the contact area between gas/liquid phases, critical for efficient olefin purification.
Q2: How does ceramic structured packing outperform metal or plastic alternatives in olefin purification?
A2: Ceramic packing offers unmatched chemical inertness, higher temperature tolerance (up to 1200°C), and longer service life, making it ideal for refining environments with corrosive impurities or extreme temperatures where metal/plastic packing may degrade.
Q3: What are the typical operating conditions for 100y ceramic packing in olefin plants?
A3: It operates under temperatures up to 1200°C, pressures up to 10 MPa, and is compatible with process streams containing H2S, CO2, and other acidic gases, ensuring stable performance over extended periods.
