Ceramic Tower Internals – Installed Inside Tower Equipment
Ceramic tower internals refer to the structural and functional components used for supporting, distributing, or optimizing processes within ceramic towers, widely applied in industrial processes such as chemical reactors, distillation units, and filtration systems.
Advantages of ceramic materials
Compared to metals, plastics, and other materials, ceramic materials exhibit significant advantages in various applications, including:
- High-temperature resistance. Ceramics can withstand extreme temperatures without degradation, making them ideal for high-temperature processes.
- Chemical resistance. They have strong resistance to corrosive chemicals, acids, and bases, making them very suitable for chemical processing environments.
- Hardness and wear resistance. Ceramic materials are extremely hard and durable, with excellent wear resistance, making them particularly suitable for high-wear processes.
- Low thermal conductivity. This characteristic provides good thermal insulation, suitable for scenarios that require heat retention or thermal protection.
- Lightweight. Compared to metals, ceramic materials are lighter, helping to reduce the overall weight of equipment and enhance usability.
- Cost-effectiveness. Due to the high durability and low maintenance requirements of ceramics, they are often more economical in the long run.
- Environmental stability. Ceramics exhibit excellent stability in harsh environments, maintaining performance over long periods without significant degradation.
Common products
Product one: Ceramic Liquid Distributor
The ceramic liquid distributor is a key internal component in packing towers, reaction towers, or other mass transfer equipment, used to evenly distribute liquids and gases, ensuring that the liquids and gases effectively cover the packing surface, thereby improving mass transfer efficiency and equipment performance.
- Structure and Design
The structure of the ceramic liquid distributor includes a basin-shaped distributor body, with ventilation holes arranged in the middle of the distributor body and convection holes spaced around the perimeter. The upper ends of the convection holes are equipped with overflow outlets, while the lower end surface of the distributor body, located around the convection holes, is fitted with a flow restriction groove. This design not only ensures that the liquid is evenly distributed across the entire tower cross-section, avoiding phenomena such as channeling, bypassing, and wall flow, but also reduces the impact of magnification effects and end effects, thereby improving separation efficiency.
- Specifications and dimensions
Ceramic distributors are mainly suitable for packing towers with a diameter of less than 1.5 meters, and specific dimensions and specifications need to be customized according to requirements.
- Type
Ceramic liquid distributors come in two types: with a cap and without a cap, with various specifications such as a diameter of 500 mm, to meet the needs of different industrial applications.

Product Two: Ceramic Multi-Beam Packing Support Plate
Ceramic saddle support grid is an efficient packing support device, mainly made of aluminosilicate or high-quality ceramic clay, featuring corrosion resistance, high temperature resistance, high strength, and large free area. It is widely used in drying towers and other packing towers as a supporting structure for bulk packing.
- Structure and design
The ceramic saddle support grid is assembled from multiple supporting beam components, forming a three-dimensional supporting grid. This design helps to increase the opening area, which typically accounts for about 70%-80% of the tower's cross-sectional area. The design principle for the opening area is that the opening ratio must be greater than the porosity of the packing layer; otherwise, the support plate may become a 'bottleneck' area, reducing the tower's load capacity and operational efficiency.
- Specifications and dimensions
The maximum diameter of the ceramic saddle support grid can reach 10 meters, and specific dimensions and specifications can be customized according to requirements. We can recommend and design the most suitable ceramic saddle support grid based on the operating conditions of the tower.
- Installation requirements
When installing the ceramic saddle support grid, it is essential to clean the oil and rust from the support surface and ensure the accurate positioning of the main support beam. After installation, the support grid should meet certain levelness requirements to ensure the stability and operational efficiency of the equipment.

Product Three: Ceramic Structured Packing
Ceramic structured packing is an efficient mass transfer packing made from ceramic materials, named for its regularly arranged geometric structure. It is widely used in processes such as separation, absorption, distillation, and desulfurization in industries like chemical, petrochemical, and environmental protection.
- Structure and Design
Ceramic structured packing is composed of many packing units with the same geometric shape, featuring a surface with good hydrophilicity that can form a very thin liquid film. Its unique design promotes gas flow through the turbulent liquid film and the inclined, tortuous gas flow channels, while not obstructing the airflow. This structure allows ceramic packing to perform comparably to metal packing, while excelling in corrosion resistance and high-temperature performance. Its surface structure not only has excellent wetting properties but also accelerates liquid flow, thereby reducing the liquid hold-up in the packing and minimizing the risks of overheating, polymerization, and coking.
- Performance characteristics
- Large flow capacity. The new tower design can reduce the tower diameter, while the renovation of old towers can significantly increase processing capacity.
- High specific surface area. Enhances gas-liquid contact efficiency and improves mass transfer effects.
- Excellent thermal stability. Capable of stable operation in high-temperature environments.
- Strong corrosion resistance. Particularly resistant to corrosive substances such as H 2 S and chlorinated naphthenic acids.
- High mechanical strength. Strong pressure resistance, suitable for high-load working environments.
- Long lifespan. Highly durable, reduces replacement frequency, and lowers maintenance costs.
- Type
Ceramic corrugated packing is divided into two types: X-type and Y-type, based on the vertical inclination angle of the corrugation.
- X-type: The inclination angle is 30°, which has a lower pressure drop and is suitable for applications with high pressure drop requirements.
- Y-type: The inclination angle is 45°, providing better mass transfer performance and is suitable for situations with high mass transfer efficiency requirements.
These two types of classifications balance the demands of pressure drop and mass transfer efficiency.
