2）Bi-Intalox Saddles Packings

双矩鞍环填料 

 

Bi-intalox saddles packings have the following advantages as to increase the surface renewal process in mass transfer of vapor-liquid and liquid-liquid, to increase cross-sectional area between two phases, improve flow performance, reduce the liquid holding quantity, reduce the probabilities of wax collection and block, increase two-phase flow immunity, reduce the mass transfer resistance, enhance the mass transfer rate and improve the mechanical strength of the packings, with cancelling the flanging structures in CMR and IMTP.

双矩鞍环填料，由于取消CMR和IMTP的翻边结构而加速了汽液或液液的 传质表面更新过程，增大两相流通截面积，改善流动性能，降低了液体的持液量，减少了液体聚焦和堵塞填料的机率，增加两相的流动扰度，减小传质阻力，提高传质速率，同时提高填料的机械强度。

 

 

3）Flat Ring Packings

扁环填料

 

The flat ring packing is divided into nine cells, which can further improve the surface area, mechanical strength and mass transfer efficiency, and reduce the pressure drop. The internal structure of this delicate can cut a continuous phase fluid, restrain the non-ideal flow. When the diameter is same, unit volume of the flat ring packing surface area ratio is higher than that of cascade ring packing and Pall ring packings which introduced from overseas. When the two phases flow through the packing layer, the resistance drop is lower, and the axial mixing is smaller, which can help to improve the operating capacity and mass transfer efficiency.

将扁环分割成九个小区，进一步提高了填料的比表面积、机械强度和传质效率，并有效的降低填料的压降。 这种精巧的内部结构也可更好地切割连续相流体，抑止非理想流动。当直径相同时，填料的单位体积的比表面面积高于阶梯环和鲍尔环等国外引进的填料。两相逆流通过填料层时阻力降较低，轴向混合较小，有助于进一步提高填料的处理能力和传质效率。

 

 

4）Double Directional Metal Folding Corrugated Packing

 双向金属折峰式波纹填料

 

Double directional metal folding corruged packing is of a new type of structured packing, which is developed on the based of combination with regular packing and Intalox bulk packing. The optimization of the packing in the structure can improve the flow paths, the mass transfer efficiency and the opening yield, and lower the performance pressure drop, increase the specific surface area, the anti clogging ability, the packing rigidity and so on, which better than Mellapak. 

该填料是在普通波纹板规整填料与Intalox散堆填料的优良组合基础上开发出的一种综合性能优良的新型规整填料。填料在结构上的优化使气液流路得到优化，传质效率提高，开孔率提高，压降更低，比表面积提高，理论板数有所增加，抗堵塞能力、填料刚度等方面均优于Mellapak填料。

双列叶片式进气分布器

 

For the larger diameter of the tower, double blades inlet distributor is a kind of excellent performance of initial gas distributor. The distributor can make the inlet gas flowing more evenly and uniformly, which can improve the better performance efficiency and sharply reduce the space height for gas to achieve uniform distribution. The use of the above technology can help reaching a strong guarantee for the process.

对于直径较大的塔来说，双列叶片式进气分布器是一种性能比较优良的进气初始分布器。采用此分布器后，使进入塔内的气体上返后更加均匀，这对于大直径的塔器可以更好地发挥填料及塔板的效率，同时气体达到均匀分布的空间高度也大大降低。以上技术手段的运用，对工艺目标的达成起到了强有力的保障作用。

The packing rings is adopted of transparent grid structure, to avoid the end effects of packings and influence of gas-liquid mass transfer.

带云梯梁的填料压圈用在填料段上端，起到压紧填料的作用。设置云梯梁可以保证压圈的整体平整度，同时还作为液体分布器的支撑梁，这种结构占位空间低。压圈采用通透式栅板结构，能够避免填料的端效应，不会影响填料的气液传质。
