Super Raschig rings are among the most prominent fourth-generation random packing products. This generation began in the 1990s. These types of packings were widely introduced to the market from 1995 onward and saw extensive use in chemical processes across various industries such as petrochemicals and refineries, as well as in purification applications, demonstrating outstanding performance. In addition, this product can be used under vacuum, at atmospheric pressure, and at high pressure. Exceptionally low pressure drop, high capacity, and excellent mass transfer efficiency are distinguishing features of this type of packing compared with other packings. Also, the gas flow exiting these packings is uniform and the pressure drop is reduced due to the alternating wavy structure of this packing type.
The Super Raschig ring structure is designed to prevent droplet formation and film generation. Special attention to the Super Raschig ring is due to its superior properties compared with other random packings and its exceptional characteristics, which are very close to those of structured packings.
Research comparing Super Raschig rings with structured packings shows that, given the same specific surface area, the mass transfer efficiency of Super Raschig rings is higher than that of structured packings.
Extensive chemical engineering data have proven that these packings are suitable for both scrubbing and absorption/desorption applications and exhibit outstanding performance.
Numerous mass transfer processes have been carried out up to heights of about 11 meters without liquid distributors using this type of packing. This height is made possible by the uniform distribution of Super Raschig rings in the column, their unique geometry, and the prevention of mass transfer losses within the column.
Using Super Raschig rings increases load capacity by up to 30%, reduces pressure drop by approximately 70%, and improves mass transfer efficiency by more than 10% compared with the use of other random packings.
