Structured Packing is a kind of packing arranged and stacked in accordance with uiform geometry in the tower.The geometry of the whole tower section is regular,symmetrical and uniform, and the gas-liquid flow path is specified ,which reduces the phenomeneon of channel flow and wall flow, and the pressure drop can be very small.Under the same energy cost and pressure drop, it can provide more specific suface area than random packing, and achieve higher mass transfer and heat transfer efficiency in the same volume. In recent decades, structured packing has been widely used in many towers in fine chemical industry,perfume industry,oil refining,fertilizer,petrochemical industry and the other fields. Structured packings are available in two different inclination angles,ie. Type X and Type Y. The type Y packings have an inclination and angle of about 45 from the horizontal axis, and are the most widely used.The type X packings have an inclination angle of 30 from horizontal axis and are used in high capacity and low pressure drop applications.

It is a earliest development of random packing, which its height is equal to outside diameter. Raschig Ring was invented by German Chemist Friedrich Raschig in 1914, it also marks that the development of fills hds entered a scientific track. However, in the actual application, Such as ” Wall flow, Channel flow and so on” often happened in Packed bed. ?

Plastic snowflake ring is a high-effciency tower packing which was named byb its shape.lt has a low specifc gravity, high flooding point, large porosity, high mass transfer unit height.Besides, this random packing has lower pressure drop, which reduces the back-pressure phenomenon and minimizes the energy consumption of the stripping process.Plastic snowflake ring is very economical.it can be applied in the chlorine and bromine production,air separation and water cooing process.  

Flat ring is also called SMR(Super Mini Ring), It s an advanced random packing in the column tower packing. It has similar structure with cascade mini ring, There is not flanging structure at the top and bottom. It can improve the packing strength through adjust the arc of internal blade. It has reasonable flow structure, low pressure drop and high mass transfer performance. Super mini ring has two main types, which names as QH-1 and QH-2.  

It was one improved ring based on Intalox ring’ s structure. The biggest improvement is that Intalox saddle’ s arc profile will be change wavy or jagged profile. meanwhile, increase some pores in the arc liquid channel’ s middle position. This structure’ s change not only increase packing’ s contacting gap, but also improve gas & liquid’ s movement and distribution in packing layer

Owing to this pack’ s shape is like saddle, so called saddle ring or Berl Ring. The earliest saddle ring’ s material is ceramic. In our actual application, when gas flows upward, liquid will flow downward along with arc channel. This Movement way will directly reduce wall flow’ s happening. However, Arched external frame also cause overlapping & bridging .Therefore, scientists change two ends into rectangle type contact surface. This improvement will reduce bridging’ happen.

It was developed by British company MTL Ltd, which also called CMR. Ceramic Cascade Ring is a new type of bulk packaging with the advantages of high capacity,good stain resistance and low pressure drop.Its sides have one or two beveled edges, which have hhigher mechanical strength and better gas passage than pall rings.Ceramic cascade rings feature a rectangular opening,curved leaves,tapered edges, and reduced height

At present, VOCs treatment mainly uses activated carbon. Since activated carbon cannot be analyzed at high temperature, it is replaced regularly. However, activated carbon adsorbed with organic matter is a dangerous chemical with high processing cost.This environmentally friendly adsorbent material is hydrophobic molecular sieve, which is different from ordinary molecular sieve in that it preferentially adsorbs water in gas. It has a highly selective adsorption capacity for organic matter, and can be resolved at high temperature, thus realizing continuous adsorption-regeneration.The adsorption material is made into a cellular structure by a special preparation process. The adsorption capacity of organic matter is more than 2%, which can be adsorbed and regenerated for a long time. Honeycomb Molecular Sieve adopt adsorption system to reduce exhaust gas concentration and air volume, and at the same time cooperate with catalytic combustion technology to reduce operating cost.
