Carbon/Graphite Raschig Rings

Corrosion reistance, thermal shock resistance, and high temperature stability are benefits from these Carbon Rings.

TYPICAL APPLICATIONS
MTL Carbon/Graphite Raschig Rings offer long packing life and high efficiency for many corrosive and high temperature separations. These Rings are excellent for applications including:
• Halogen acid processing
• Hydrofluoric acid manufacturing
• Phosphate fertilizer manufacturing
• Sodium/potassium hydroxide scrubbers
• Applications involving high thermal shock

Stocked in six size to meet all packed tower requirements.

 

FEATURES

Low coefficient of thermal expansion, resists damage caused by severe shocks.

May be used in most acids, alkalies and solvents. (Not recommended in highly oxidizing conditions.

Light weight and high mechanical strength with no soluble bond.

Long life packing with high temperature operating capabilities. Used in chlorine-hydrochloric mixtures and phosphoric acid.

Fully carbonized to eliminate extractable impurities.

CERAMIC SADDLE

TYPICAL APPLICATIONS
Ceramic Saddles are traditional shapes produced from chemical porcelain or stoneware. Ceramic packings are fired at high temperatures and have excellent mechanical, abrasion, and heat resistance. Ceramic packing is commonly used in heat transfer and corrosive acid applications.

CHEMICAL RESITANCE
Excellent chemical resistance at high temperatures.
Ceramic saddles are produced in accordance with newly developed manufacturing processes. These processes ensure the production of smooth, beveled and longitudinally ribbed bodies that are consistent and uniform in shape. This eliminates fluctuations in the product performance and makes accurate predictions of operating efficiencies possible. During manufacture, quality assurance testing is conducted in accordance with ASTM and DIN standards, and includes chemical analysis, maintenance of physical properties, and end-product chemical resistance.
These saddles are particularly suited for applications involving thermal shock conditions or continuous high temperature operations. The saddles are fire at 1200° C which results in better resistance to breakage from thermal shock conditions.

BENEFITS
Excellent chemical resistance at high temperatures.

Excellent resistance to thermal shock conditions.

Good wetting characteristics.

High mechanical strength.

Abrasion resistant.

CERAMIC SUPER SADDLE

APPLICATIONS
One of the major mass transfer benefits of this tower packing is its shape; a saddle shape that provides two of the most important criteria of any tower packing: (1) maximum usable area for liquid and gas contact;(2) minimum resistance to liquid and gas flow through the column.

Regardless of how ceramic packing falls when randomly dumped into a tower, the unique saddle shape minimized pattern packing. It is impossible for any two saddles to cover one another to a degree which would significantly reduce the effective surface area for liquid and gas contact.

Super saddles also offer the advantage of random configuration and efficiency, but provide the additional benefit of 86% (or more) increase capacity when compared to Raschig rings.

CHEMICAL RESISTANCE
Chemical stoneware and chemical porcelain packings resist all acids, alkalies and solvents, other than hydrofluoric acid and hot caustics.

Porcelain is superior to stoneware in hot caustic service because it can withstand 10% sodium hydroxide service up to 52° C (125 degree F) and 1% sodium hydroxide service at temperatures up to 93° C (200 degree F)

RECOMMENDED USES
The chemical resistance and economical installation of ceramic packings have led to their use in many mass transfer applications including; hot potassium carbonate; chlorine cooling and drying, absorption; mercaptan removal; natural gas or LPG sweetening; and corrosive distillation.
