Ceramic combination ring for oil refining gas chemical wash off

1.large specific area, 2.Low resistance, 3. uniform flow distribution, 4.High separation efficiency 5. high quality

 Ceramic combination ring  is a kind of new pattern and high efficient packing which aim at th special demand of clearing, extracting and rectification in the chemical, oil refining and coal gas industries. This structured packing is polygon, increase combing intension and surface area, and improving greatly on the loading and the filling of the simple and whole of the packing, that is dredging in the length and breadth, perforating floor and floor, that making the gas and liquid distribute equably, basely solving the question of flowing ambagesly. The velocity of reaction improve greatly after amlerating.The whole weight of the load and fill decrease consumedly, bringing on the producing efficiently and economic benefit improving in phase.

Light ceramic structured packings is widely used as the chemical packing of desulfurizing, washing, debenzolization, naphthalene-cleaning, rectification, absorption, drying tower in chemical-processing coal and fine chemicals industries, such as petroleum, coking, generating, fertilizer, synthetic ammonia. And it is also used as cooling packing in watering tower.
