Metal Saddle Rings Characteristics And Use Occasions

Metal saddle rings are processed by continuous extrusion. Compared with Raschig ring packing of the same material, they have the advantages of large flux, low pressure drop and high efficiency. Compared with ball rings, they have lower resistance, larger flux, higher efficiency, better packing strength and rigidity. They are currently a widely used random packing.

It has a large porosity, and the bed layer is mostly arc-shaped liquid channels, which reduces the resistance of gas passing through the bed layer and also reduces the radial diffusion coefficient of liquid when it flows downward. Its shape is between the ring and the saddle, so it has the advantages of both. This structure is conducive to liquid distribution and increasing gas channels. Because of its high density and excellent acid and heat resistance, it can resist corrosion from various inorganic acids, organic acids and organic solvents except hydrofluoric acid.

Product characteristics of metal saddle rings:

It can be widely used in distillation, absorption and other reactions.

It can be used in vacuum towers and high-pressure towers.

It can be applied to mass transfer towers of different diameters. It is often used in vacuum towers, where low gas pressure drop is crucial. It is also often used in high-pressure towers, where the capacity greatly exceeds that of typical trays.

Occasions for use of metal saddle ring products:

Stainless steel saddle packing has a very good application effect in equipment such as oil refining, petrochemicals, coal chemicals, fine chemicals, and environmental protection. For example, the use of saddle rings in the dewaxing phenol refining extraction tower in the refinery can increase the processing capacity by 15%-20%, increase the yield by 1-2%, and improve the refined oil obtained. It is also ideal for use in demethanizers, deethanizers, condensate stripping vacuum distillation towers, phthalic anhydride refining towers, refinery ethylene vacuum towers, lubricating oil fraction oil reduction distillation towers, etc. in ethylene production units.
