100y ceramic structured packing is a specialized type of ceramic填料 (packing) designed to optimize separation efficiency in chemical processes, particularly in cumene purification. As a key component in distillation columns, its structured design ensures precise fluid distribution and enhanced mass transfer, making it indispensable for refining cumene—a vital intermediate in polymer and chemical manufacturing.

Key Features and Product Overview
The 100y ceramic structured packing derives its name from its specific geometric structure, characterized by a 100-micron wire gauze or metal grid with a uniform, periodic arrangement. Made primarily from high-purity ceramics such as cordierite or alumina, it exhibits excellent thermal stability, chemical inertness, and mechanical strength. This material composition allows it to withstand harsh operating conditions, including high temperatures and exposure to aggressive chemicals, common in cumene production environments. With a high specific surface area (typically 150-350 m²/m³) and optimized pore size distribution, the packing ensures efficient vapor-liquid contact, reducing the number of theoretical plates required for separation and lowering energy consumption in distillation units.
Applications in Cumene Purification
In cumene purification, the primary goal is to separate cumene from impurities like benzene, toluene, and other aromatic hydrocarbons. 100y ceramic structured packing excels in this task by enabling precise fractional distillation. Its structured design minimizes channeling and maldistribution, ensuring that each component in the feedstock is effectively separated. This leads to a higher purity of cumene (up to 99.9% or more) and reduces the formation of byproducts, which is crucial for downstream processes such as cumene dehydrogenation to produce phenol. Additionally, its durability extends the packing lifespan, reducing maintenance frequency and operational costs for chemical plants. For example, in industrial settings, replacing traditional random packing with 100y ceramic structured packing has been reported to increase separation efficiency by 20-30% while cutting energy usage by up to 15%.
FAQ:
