Ceramic Pall Ring

The Pall ring is a kind of new type and high efficient packing that is improved on the basis of the Raschig ring. Yuanying pall ring is a proven design that provides higher capacity and lower pressure drop than trays and other random packing. The opened cylinder walls and inward bent protrusions of the Pall Ring allow greater capacity and lower pressure drop than standard cylindrical rings. This open ring design also maintains an even distribution and resists wall-channeling tendencies. The interior and exterior contacting surfaces of the Pall ring provide for an effective distribution of liquids and gasses and resist plugging, fouling and nesting.

Raschig ring is proven in a wide range of mass transfer applications. Raschig ring structure provides one of the largest surface areas among tower packing options and handles heavy loading, process upsets and temperature shocks.

Intalox Saddle

2) Outstanding surface utilization in mass and heat transfer applications.

3) Shorter packed bed heights

4) Maximum piece-to-piece contact with minimal nesting

5) High strength to weight ratio allows up to a 15 meter bed height

Ceramic Intalox Saddle

Ceramic intalox saddle is improved from the arc saddle, it changes the both arched surface to rectangular surface and makes the interior and exterior radius of curvature different, this construction overcomes the problem of nesting basically, it makes porosity distributed even and improves the distribution of the fluid, greater capacity and lower pressure drop than Raschig ring.

Owing to conjugate curve rib structure and appropriate length, there are point contact and aren’t intussusceptive between packing and tower or packing. Yuanying Conjugate ring has better hydrodynamics and mass transfer performance. It is applied to distillation, gas absorption, deadsorption system

Conjugate ring is used in both deep vacuum and high pressure towers. Conjugate ring is high performance random packing successfully used in mass transfer towers both small and large diameter. Conjugate ring is frequently used in deep vacuum towers where low pressure drop is crucial and also high pressure towers where capacity significantly exceeds conventional trays.

Cascade Mini Ring

It is especially suitable for rectification towers under vacuum to treat thermo sensitive, decomposable, polymerizable or cokable systems, so it is widely used in packing towers in petrochemical industry, chemical fertilizer industry and environmental protection, etc.

Cascade mini ring advantage

1) Reduced pressure drop

Reduced Pressure drop occurs because Cascade Mini Ring has its largest opening predominantly in the direction of the vapor/liquid flow which allows for easy passage, this reduces the pressure drop significantly.

2) Increased plant capacity

Increased plant capacity is the direct result of the result of the reduction in pressure drop that Cascade Mini Rings provide, as this moves the operating point further away from the “critical pressure drop point” at which flooding occurs. This is typically 1-2 in., wc/ft or 10-20 mbar/in). This effect allows additional vapor/liquid handling and therefore increases plant capability

3) Improved resistance to "fouling"

Improved resistance to fouling results from the directional positioning of cascade mini rings, (largest opening in direction of flow ) as any solids entering the packed bed are more easily flushed through the packing matrix.

4) Higher operational efficiency

Higher operational efficiency occurs because of the preferential orientation which ensures that in most of the ring surface are positioned vertically rather than horizontally, and this is also advantageous for mass transfer. High efficiency is dependent on as much of the available surface area as possible being effectively wetted. The underside of any horizontal surface in a packed bed or tower is naturally shielded from the liquid trickling down and is therefore not fully wetted, such dry surfaces play little or no part in the mass transfer process. Yuanying Cascade Mini Ring significantly reduces this effect, and therefore gives much higher plant operational efficiency.
