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 AceChemPack 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).
Performance of Cascade
Mini Ring:
This preferential orientation of the AceChemPack Cascade Mini Ring (CMR ring) brings about substantial
improvements in process performance: 1. Lower pressure drop:
Having its largest opening predominantly in the direction of the vapor flow
allows for easy vapor passage, resulting in lower pressure drop.
2. Higher capacity:
The lower pressure drop moves the operating point farther away from the critical
pressure drop at which flooding occurs (typically 1-2 in. wc/ft or 10-20
mbar/m). This means additional vapor/liquid handling capability.
3. Better fouling resistance:
Any solids entering the packed bed are more easily flushed through the packing
matrix by the liquid. 4. Higher efficiency:
This preferential orientation of the AceChemPack Cascade Mini Ring
(CMR packing) , resulting in most of its
surface being positioned vertically in the tower rather than horizontally, is
also advantageous for mass transfer. It is important that as much of the
available surface area as possible be effectively wetted. The underside of any
horizontal surface in the packed bed is shielded from the liquid trickling down
and is therefore not effectively wetted. By definition, these dry surfaces take
no part in the mass transfer process and are lost.
Substituting PALL-RING with AceChemPack Cascade Mini Ring (CMR
ring) will, therefore, result
in clear capacity and pressure drop and/or efficiency gains, depending on which
option the designer chooses.
The high strength-to-weight ratio of the CMR packing allows the use of deep beds
while minimizing the number of support plates and redistributors. CMR packing
also resists compression making removal easy during turnarounds.
