Ceramic Structured Packing: An Effective Assistant in Chemical Separation

In the modern processes of mass transfer separation such as distillation and absorption in fields like chemical engineering, petrochemical industry, and environmental protection, the core components inside the towers play a crucial role. Ceramic corrugated structured packing is precisely such an efficient mass transfer element. It is composed of multiple ceramic thin plates with specific corrugated geometric structures, which are vertically and precisely staggeredly stacked and combined at an angle (usually 45°or 30°) to form a series of uniform, parallel regular triangular or sine curve-shaped channels within the tower. This meticulously designed structure aims to maximize the contact surface area between the gas and liquid phases, guide the fluids to distribute uniformly along a specific path, significantly enhance the mass transfer efficiency, effectively reduce the system pressure drop, improve the separation performance and lower the energy consumption.

The ceramic structured packing material is usually made of high-performance ceramic materials. Alumina is the most common choice, which offers excellent hardness, wear resistance and chemical inertness. According to the requirements, the content of alumina can range from 70% to over 99%. High-purity alumina (such as 99 porcelain) has excellent corrosion resistance.

The ceramic structured packing has excellent properties:

1. High capacity. So that, in new tower design may reduce diameter, while retrofitting old towers may increase capacity significantly.

1. High separation efficiency owing to much large specific surface.

2. Low pressure drop leads to reduce energy consumption largely.

The ceramic structured packing has established an unshakable position in the field of chemical separation due to its robust body composed of high-performance ceramics (such as alumina and silicon carbide) and its precise and regular corrugated channel structure. It perfectly integrates the ultimate corrosion resistance, high-temperature resistance, efficient mass transfer capability, excellent fluid distribution, and outstanding anti-blocking properties. In extremely harsh working conditions such as strong acids, strong bases, high temperatures, corrosive media, and easy scaling, the ceramic corrugated regular packing material demonstrates an irreplaceable advantage and becomes the key "rock" ensuring the long-term, stable, and efficient operation of the equipment.
