A Leader In Mass Transfer Tower Packing Since 1988. - JIANGXI KELLEY CHEMICAL PACKING CO., LTD

Plastic Raschig Ring with PP/PE/CPVC

Before the invention of the tower packing shape by Frederick Raschig in 1914, Plastic raschig ring is the most early-developed product in random packing.It has a simple shape with equal length at its diameter and height.It provide a large surface area within the volume of the column for interaction between liquid and gas or vapour.

packed columns were filled with quartz, broken glass bottles, broken pieces of pottery, or coke. Operating data obtained from one tower could not be used in a second tower as the packing material was not consistent.

The invention of the Raschig Ring gave the packed column consistency and dependability. Raschig Rings significantly improved the operating characteristics of the column, enabling the performance of the packed column to be duplicated in a second column of equal size.

Because of their low cost, Raschig Rings remain one of the most widely used tower packing materials.

Feature

 High void ratio, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high efficiency of mass transfer.

Advantage

1. Their special structure make it has big flux, low pressure drop, good anti-impaction capability.2. Strong resistance to chemical corrosion, large void space. energy saving, low operation cost and easy to be load and unload.

Application

These various plastic tower packing are widely used in petroleum and chemical,alkali chloride,gas and environmental protection industries with max. temperature of 280°.
