The earliest random packing Plastic raschig ring

Plastic Raschig ring is a earliest development of random packing,which its height is equal to outside diameter. Since Plastic Raschig Ring was invented by German Chemist Friedrich Rashig in 1914, Tower packing’s development had entered the track of science.In actual application, owing to its closed cylindrical structure, it will easy to lead to liquid’s bias flow,channel flow and wall follow phenomenon’s happen. Furthermore, big liquid hold-up in packing layer will increase air & liquid passing time and form big resistance. Since 1940s, Plastic Raschig Ring has been gradually replaced by Pall ring. However, owing to Raschig ring gave the packed column consistency and dependability,so Raschig Rings remain one of the most widely used tower packing materials,so it is one of the most widely used tower packing materials.

high flooding point & evenly gas-liquid distribution plastic ralu ring

Plastic Ralu ring is an improved Pall ring. The mainly improvement is to increase two ends turn-ups and wall’s thickness. If existing columns are equipped with Plastic Ralu ring’s, a decrease in operating costs and higher separation efficiency at a constant bed height will be achieved. At an unchanged separation efficiency, the bed height can be reduced, thus decreasing the pressure drop.Two ends turn-ups is similar Cascade Mini Ring structure. When liquid passing Plastic Ralu ring surface, it will follow down along with two turn-up.Meanwhile, inner wetteable surface area is bigger than pall ring. Therefore, Plastic Ralu ring can replace the Pall ring in some fileds.

Plastic Super Intalox Ring

Plastic Super Intalox Ring was one improved ring based on Intalox ring’s structure. The biggest improvement is that Plastic Super 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.Plastic super intalox ring channel is like Open Semi-Round or Arc Type. It is not speed up air & liquid movement and contacting, but also decrease movement resistance. However, Open Semi-round or Arc Type also caused Plastic Super intalox saddle’s overlapping and interweaving. Instead, it will lead to a decrease in mass transfer efficiency.Further, it is less sensitive to liquid distribution quality and has higher liquid hold-up and residence time for those services that benefit from such characteristics.

Liquid collection redistributor

Liquid collector’s major function is collecting the liquid and re-distributing the gas. Usually, liquid collector is in the top of packing bed. The distance between liquid collector & packing bed is 150-200 mm.When the liquid falling down along with packing,due to upward gas’s speed is not same, gas’s speed toward center is big and toward tower wall is small. It is very easy to form wall flow phenomenon. In order avoid of wall flow phenomenon’s happened and improve mass transfer efficiency, we should install liquid collector or liquid re-distributor to improve liquid’s evenly distribution. Of course, according to different processing requirement, we can install one or many Liquid collectors in the different height’s position.

Outstanding 250x 250y Chemical Tower Structured Packing Metal Corrugated-Plate Packing

Metal Corrugated-Plate Packing is designed to enhance mass transfer efficiency in industrial separation processes like distillation, absorption, and extraction. Its corrugated metal structure increases surface area, allowing for better gas-liquid contact and reduced pressure drop. Widely used in chemical plants, it ensures durable, energy-efficient separation.
