Ceramic Corrugated-Plate Structured Packing Ceramic Structured Packing
Ceramic Corrugated Packing
As a major type of tower packing, ceramic corrugated packing is widely applied in equipment such as rectification towers, absorption towers, extraction towers, heat exchangers and mist eliminators for industrial processes in the petrochemical, fine chemical and environmental engineering industries. Ceramic materials feature excellent corrosion resistance and are generally resistant to the corrosion of various inorganic acids (except hydrofluoric acid) and all kinds of solvents. For an important application, ceramic materials are often processed into tower packing of various shapes and specifications.
Since their advent, ceramic packing has developed rapidly due to its advantages of corrosion resistance and low cost, and new types of ceramic packing have been continuously developed. Ceramic corrugated packing is a new type of structured packing that has been widely used in recent years. As a kind of structured packing, it is fired from ceramic corrugated plates.
1. Characteristics of Ceramic Corrugated Packing
(1) The specific surface area of ceramic structured corrugated packing is larger than that of random packing, with an increase of more than 15%.(2) The wettability of the ceramic corrugated packing surface is improved, which increases the wetted specific surface area of the packing, thereby raising the interfacial area and mass transfer efficiency of the packing. It intensifies the disturbance of the gas-liquid two phases, facilitates the surface renewal of the liquid and increases the liquid surface renewal rate, thus improving the mass transfer efficiency of the packing.
2. Geometric Characteristics of Ceramic Corrugated Packing
Geometric characteristic data include tray diameter, tray height, peak height, wave pitch, wave length, tooth angle, corrugation inclination angle and bulk density, which are the basic parameters reflecting the geometric characteristics such as the specification and shape of the packing.
Methods for Determining Geometric Characteristics
- Direct measurement method: Used to determine the tray diameter, tray height, peak height, wave pitch, wave length, tooth angle, corrugation inclination angle, specific surface area and porosity.
- Weighing method: Used to determine the bulk density.
- The hydrodynamic performance is generally expressed by the pressure drop per unit height of the packing layer passed by gas, while the mass transfer performance can be expressed by either the height equivalent to a theoretical plate (HETP) or the height of a transfer unit (HTU), with different determination methods for the two parameters.
