Cascade Mini Ring high-performance random packings provide significant capacity advantages and lower pressure drop than other random packings. These high-performance random packings have consistently demonstrated capacity improvements of up to 15% in a variety of applications without loss of efficiency. Superior mechanical integrity allows processors to specify deep beds without packing deformation. Both high performance packings are available in several sizes and virtually any metallic material. Cascade Mini Ring random packings are the most advanced random packing designs offered today. Low Aspect Ratio (1/3 to 1/2 of H/D)- Key to Highest Performance for Mass Transfer. Cascade Mini Ring is the successful third-generation random packing. Since its introduction, CMR random packing has been utilized in a wide variety of distillation, absorption and stripping columns around the world. The superior performance of CMR random packing has been shown in thousands of successful installations.

CMR is the random packing of choice for the majority of licensed processes. Among the many random packings available on the market, the PALL-RING has been popular for several decades. Characteristic of the PALL-RING (and most other cylindrical ring-shaped packings) is the fact that the ring height is equal to the ring diameter, i.e., the height-to-diameter ratio is equal to 1.0. The Cascade Mini Ring random packing has an aspect ratio of only 1: 3, i.e., its height is typically only 1/3 of its diameter. Seemingly minor, this change in geometry has a profound effect on the process performance of the packing. Indeed, when dumped in a tower, the "flat" CMR rings tend to orient themselves preferentially in a "near-horizontal" position, i.e., with their cylindrical axis predominantly in the direction of the vapor and liquid flow. This is exactly the opposite of the tendency of PALL-RING (and other high-aspect-ratio rings) to preferentially orient themselves on their "side" (cylindrical axis more horizontal than vertical).
