Which alumina grade of inert ceramic ball should I choose for catalyst bed support?

Standard 17–23% Al2O3 inert balls suit most hydrotreating and reforming catalyst supports. Choose 23–30% for higher crush strength, and 99% alumina where high-temperature steam could cause silica leaching that would poison downstream catalysts.

What information do you need to recommend tower packing?

Please share the tower diameter and bed height, the service (distillation, absorption, stripping or scrubbing), the medium and its corrosivity, operating temperature and pressure, and any pressure-drop or capacity targets. Our engineers then propose packing type, material and size.

Can I receive samples and technical data sheets before ordering?

Yes. Samples of standard sizes and technical data sheets covering chemical composition, bulk density, crush strength and other key properties can be provided for evaluation before a production order.

How are ceramic and metal packing products packed for export?

Depending on product and volume, we use cartons, jumbo bags, plastic drums or wooden cases on fumigation-free or fumigated pallets, with clear marking for each size and batch to simplify site receiving.

Where is Zhongtai located and can buyers visit the factory?

We are based in Pingxiang, Jiangxi Province, a recognized Chinese hub for industrial ceramics and chemical packing. Buyers and third-party inspectors are welcome to visit; Korean customers audited our ceramic production in July 2018.

Product Description

Introduce

Raschig Rings are an excellent distillation column filling due to their extremely high surface area and consistent, defined large void space. A benefit of using Raschig Rings as distillation column packing is that they are an inert type of packing so you don't have to worry about packing the column too tightly, which can cause choking.

Ceramic raschig ring is one of the earliest developed random packing, the structure is simple, the height and diameter are the same. Raschig rings large size (100mm or more) means the general rules by filling the entire puzzle, 90mm size raschig rings generally use the following method loading number.

Advantage

It has the characteristics of excellent acid resistance and heat resistance. It can resist to corrosion of various inorganic acids, organic acids and organic solvents except hydrofluoric acid, and can be used in high or low temperature conditions.

Frequently Asked Questions (FAQ)

1. What is the structural feature of a Ceramic Raschig Ring?

The Ceramic Raschig Ring is one of the earliest developed random packings. It features a simple cylindrical open-ended design where the outer diameter and height are equal in dimension.

2. Why are Raschig Rings effective for distillation columns?

They provide an extremely high surface area and consistent, defined void space. Being chemically inert, they minimize the risk of choking even when loaded securely in column packing operations.

3. What chemical substances can Ceramic Raschig Rings resist?

They feature exceptional corrosion resistance against virtually all inorganic acids, organic acids, and organic solvents, with the sole exception of hydrofluoric acid (HF).

4. What are the operating temperature tolerances?

Manufactured with a firing temperature between 1280°C and 1320°C and a softening point above 1400°C, they exhibit superior heat resistance suitable for extreme high and low operating temperatures.

5. What size options are available for Ceramic Raschig Rings?

Available standard nominal sizes include φ6, φ12.5, φ16, φ19, φ25, φ38, φ40, φ50, φ80, and φ100 mm, catering to various column diameters and flow velocity requirements.

6. How are large-diameter Raschig Rings loaded into columns?

Raschig rings with larger sizes (100mm or more) are generally arranged via systematic structural puzzle filling, whereas sizes around 90mm or smaller follow bulk or defined loading number methods.
