(!) Ceramic structured packing 550Y
Keywords: ceramic structured packing, ceramic corrugated packing, ceramic lightweight packing, ceramic packing
Application ● Rectification of organic halide. ● rectification and absorption of some aggressive mixtures, which are certainly regulated by the pressure drop and the theoretical plate number. ● It is used in columns that contain a large amount of natural media that are used to absorb nitric acid and concentrated sulfuric acid, as well as for air purification in chemical plants. ● Operation in vacuum conditions at a lower absolute pressure of 100pa. ● Used in heat exchanger and cleaning, or as a catalyst carrier.
A ceramic structured packing consists of many units of the same geometric design. Corrugated sheets, placed in parallel, create cylindrical blocks called a column packing. This is a form of high-quality packing with separation efficiency several times higher than that of a bulk packing. They have the quality of a low pressure drop, increased operational elasticity, minimal reinforcing effect and maximum liquid treatment compared to a bulk packing.
Advantages
● High productivity The new column design can reduce the diameter, while the reconstruction of the old columns can significantly reduce the throughput.
● High separation efficiency. Since it has a much larger specific surface area in comparison with an irregular packing.
● Low pressure drop, which leads to a significant reduction in energy consumption.
● Greater flexibility and economies of scale are not obvious.
● Suitable for all column diameters.
● High corrosion resistance for alkalis and acids, especially to H2S, naphthenic acid and Cl -.
Application:
● Rectification of organic halide.
● Absorption of several aggressive mixtures, which are determined by the pressure drop and the theoretical plate number.
● It is used in some columns that contain a large amount of natural media, which are used to absorb nitric acid and concentrated sulfuric acid, as well as to purify the air in chemical plants.
● Operation in vacuum conditions at a lower absolute pressure of 100pa.
● Used in heat exchanger and purification, or as a catalyst carrier.
