Types of corrugated structured packings

Mellapak® (Fig. 8.11 a). Mellapak® has grooved and perforated surfaces. Adjacent elements are rotated 90°. The crimp angle is 45°, and the crimp apex is sharp. Mellapak® is available in several types. The Mellapak® number denotes the nominal surface area of the packing per unit volume (m2/m3). The suffix denotes the angle of orientation to the vertical axis; Y signifies 45°, X signifies 60°. For instance, Mellapak® 250.Y has a surface area of 250 m2/m3, and a 45° angle of orientation to the vertical axis. Mellapak® is available in metals and plastics from Sulzer Chemtech in Switzerland.

Flexipac® (Fig. 8.11 b). Flexipac® is similar to Mellapak®, but not identical to it. The common Flexipac® types are Flexipac® 1 (similar to Mellapak® 500.Y), Flexipac® 2 (similar to Mellapak® 250.Y), Flexipac® 3 (similar to Mellapak® 125.Y), and Flexipac® 4. Flexipac* is marketed in the United States by Koch Engineering under a licenae from Sulzer. It is available in metals.

Gempak® (Fig. 8.11c). Gempak® has lanced and perforated surfaces. The crimp angle is 45° and the crimp apex is sharp, Gempak® is available in several types. The number denotes the inverse of the crimp height. For instance, Gempak® 4A has Vi-inch crimp height. The suffix A denotes that the packing is a standard Gempak® type with the lanced surface. A variant of Gempak® with a smooth rather than the

lanced surface is also available, and is denoted by the suffix T aft« the A; for instance, Cempak® 2AT denotes a packing similar to Gempak® 2A but with a smooth surface. Another type, Gempak® 4BG is a wire-mesh packing similar to the Sulzer® Wire Gauze BX packing (Sec. 8.1.7). Gempak® is available in metals and plastics from Glitsch Inc.

Montz B1® (Fig. 8.11d). In contrast with Mellapak®, Flexipac*, and Gempak®, the corrugations of the Montz B,l® packing are sinusoidal

rather than sharp-cornered. The surface is unperforated and embossed with small, closely spaced projections in a dot matrix pattern. The Montz Bl® number indicates the nominal surface area of the packing per unit volume (m2/m3). For instance, Montz B1-200® has a Surface area of 200 m2/m3. Montz Bl® is available in metals from Nutter Engineering Corporation. Montz also has a C series of plastic structured packings.

Intalox® high-performance structured packing (Fig. 8.11 e). Relatively flat crimps, somewhat rounded crimp apexes, and deeply embossed surfaces with tiny perforations distinguish Intalox® high-performance structured packing. It is available in three sizes in metals from the Norton Company.

MAX-PAC® (Fig. 8.11 /). With sharp crimp apexes and smooth surfaces, MAX-PAC® is distinguished by surfaces that are perforated with unique W-shape perforations (Fig. 8.10f). MAX-PAC® is available in metals from Jaeger Products, Inc.

Montz BSH (Fig. 8.100- With sharp apexes and perforated surfaces, Montz BSH® is distinguished by its expanded metal surfaces. The see-through sheets permit liquid to easily move from one side of the sheet to the other. The numbering system and the supply information for the Montz BSH® series are identical to those described above for the B1 series.

Flexeramlc® (Fig. 8.11<j). Flexeramic® has crimps with round apexes and smooth, unperforated surfaces. This ceramic packing is available from Koch Engineering Company, Inc.

Others. Other metal structured packings reported in the literature include Ralupak (3) and Rombopak (29). Plastic structured packing.

    Is mellapak same as nutter b1 200 structured packing?
