Cascade mini ring is a product which is specifically designed for reducing pressure drop and increasing plant capacity. Since its structural design increases the contact point between gas-liquid, this product is also incredibly useful in improving gas-liquid distribution in packed bed.
Available as metal cascade mini ring, ceramic cascade mini ring and plastic cascade mini ring, cascade mini rings are one of the most vital components for desulphurization in compound ammonia plants. Alternatively, they are also used in a wide range of separation processes like separation of methanol and other additional components. The overall product itself is small, compact and incredibly useful.
Like we already mentioned, cascade rings are available in metal, ceramic and plastic variants. Since each of them is equally useful, we’d individually assess their features, operation and application. The metal variants of these cascade rings come with rectangular openings and conical edges. Their height too is relatively smaller than the other variants.
The design of this ring particularly owes your attention, as it plays a vital role in promoting the renewal of the surface of a specific liquid membrane. This in turn strengthens the mass transfer performance of the cascade ring. Since the design of this ring is structurally efficient, it has better impact (in terms of separation) when compared to intalox saddles and raschig rings.
Like the metal variants, the plastic and ceramic variants of the cascade rings come with better foulding resistance, higher efficiency and better capacity. They are available in various sizes and like the metal rings, these plastic and ceramic rings too help in reducing the pressure drop.
In this section, you will find a detailed list of specifications about cascade mini rings.
Low Aspect Ratio-
One of the defining features of cascade mini rings is their low aspect ratio. This feature alone is a key to their maximum performance for mass transfer. This structural feature has a significantly positive impact on the device’s performance while packing. Additionally, it also enhances the capacity and reduces the level of pressure drop. The vertical orientation of this product assists in the free flow of gas through a packed bed.
Low Pressure Drop-
The low pressure drop along with the high capacity makes way for relatively smaller column diameter during new installations.
Multiple sizes-
Cascade mini rings are also available in multiple sizes. This allows them optimize the capacity as well as the efficiency according to the varying applications.
In this section, you will find a detailed list of specifications about cascade mini rings. Fouling resistance- This is yet another feature that goes into the making of a good cascade mini ring. This feature ensures that the solids passing through the packed bed are conveniently flushed via the packing matrix of the liquid.
Extremely Efficient-
Since cascade mini rings are extremely efficient, their surfaces are positioned in a vertical direction instead of a horizontal one. This further assists in mass transfer. While using the mini cascade ring it is extremely important that you wet a significant part of the surface area that is available to you. The lower portion of a horizontal surface in this packed bed is completely protected from the liquid that trickles down due to which it isn’t wetted as effectively. Going by the exact definition, these dry areas have no role in the process of mass transfer and are completely lost.
High Mechanical Strength-
The construction of ring and spoke offers maximum mechanical strength. This makes it easier to be used in the more relatively deep beds.

Application of metal cascade mini rings- Metal cascade mini rings are used in absorption and stripping services. They also assist in heat transfer and the desulfurization of fuel gas. Additionally, according to some manufacturers, metal cascade mini rings play a vital role as they are used by ethylene primary practitioners in quench towers.
These cascade mini rings go through a process of rigorous packing and after which they are immediately delivered to you within your desired time. The packing ensures greater interstitial transfer and further ensures the efficiency of the product when you receive it.
Cascade mini rings are available in many different price points depending on the quality and efficiency of the product. You'll find rings at a price as low as $120 and it can eventually move up to $1500 depending on the brand and the quality.
Metal cascade mini rings are made from a wide range of materials like Titanium, HC-22, monel, pure nickel and aluminium.
These cascade mini rings prevent fouling with their structural orientation. Since they are made from an open structure with a vertical axis orientation, fouling is automatically prevented as solids can now be easily flushed along the bed with liquid.
The construction of the ring and the spoke offers greater mechanical strength which further makes it easier to be used in the more deep beds.
Since cascade mini rings come with a wide range of features and uses, they are definitely the right products for anyone working in desulfurization or ammonia plants. These rings are useful, easy to operate and extremely compact. So if you're really looking to enhance the efficiency of your current and potential projects, get these rings for maximum benefits.
