Knitted Wire Structured Packing

Specific use cases for knitted structured packing include:

• Difficult separations with many theoretical stages that can benefit from higher efficiency rates
• Pharmaceutical, food and beverage and other heat-sensitive chemical processing applications that require minimal pressure drops
• Corrosive chemical processing applications that require durable materials and system designs
• Multi-purpose batch distillation towers that process a wide range of materials with different properties and characteristics
• Any tower installation with limited physical space and headroom

In addition to knitted tower packing, MACH Engineering also designs Tri-Packs®, Pall Rings, Hi-Rings and related packing materials. Because we don’t specialize in one product exclusively, we’re well-positioned to recommend the best option for your needs.

Knitted structured packing permits a high ratio of surface area to volume, which in turn improves efficiency by keeping pressure drop to a minimum. Select products can produce HETP (height equivalent to a theoretical plate) values as low as 3 inches in pilot columns, or 4 inches in high-vacuum services. This capability enables a variety of space-saving engineering possibilities.

The use of fine wires optimizes mixing and mass transfer efficiency by spreading liquids into thin streams and maximizing contact with vapor throughout the column. It also promotes uniform liquid distribution. Turndown ratios can be as high as 20:1.

Finally, knitted structured packing is easy to install, remove and retrofit while remaining highly durable and cost-effective.
