Choice and Application of Koch-Glitsch High Capacity Structured Packings
Each type of Koch-Glitsch structured packing has strong performance characteristics. Under certain conditions or in speͭcific applications, each has a particular strength which may make one style more desirable. Considerations in choosing a specific structured packing type are:
• To meet specific process requirements
• As a direct replacement of an existing packing
• Familiarity with the packing type and its performance
• Past experience of using a specific packing type in a particular application
• Specified for use in a licensed process
With more than thirty years of history, FLEXIPAC structured packing continues to be a strong performer in applications where the incremental capacity increase of high performance structured packing is not required.
When choosing a high capacity structured packing, FLEXIPAC HC and INTALOX structured packings each offer distinct advantages, depending upon the application. Through its wetting and liquid handling characteristics, the patented, aggresͭsive surface texture of the INTALOX structured packing offers extremely efficient use of the available packing surface. For the larger corrugation size packings, INTALOX structured packing provides a better efficiency than other structured packings with similar surface area.
FLEXIPAC HC structured packing uses a less aggressive, perforated and textured surface style to provide excellent surͭface area utilization. This surface, along with the smooth channel transition at the layer interface, provides a less restricted flow channel and results in lower pressure drop as the packing reaches the loading region. This is particularly true for the smaller corrugation packing sizes. The table below provides guidance in choosing the recommended high capacity packing.

INTALOX® Structured Packing 5TX
As the only high capacity, high efficiency packing available in the "X" (60°) corrugation configuration, INTALOX structured packing 5TX offers grid type packing capacity with good efficiency. INTALOX 5TX structured packing should be considered whenever fractionation or excellent heat transfer is required at the absolute maximum throughput.
FLEXIPAC® S, FLEXIGRID® and GLITSCH-GRID® Structured Packings
FLEXIPAC® S packing is similar in construction to FLEXIPAC packing but has a smooth surface and can be manufactured using thicker material. The smooth surface enables the packͭing to be used in moderately fouling systems while the thicker material gauge gives it greater mechanical strength and provides increased corrosion resistance. FLEXIPAC S packing is available in various sizes and in both the X (45°) and Y (60°)
corrugation configurations. Applications include top pumparound zones of Refinery Fractionators as well as Ethylene Water Quench Columns.
FLEXIGRID® and GLITSCH-GRID® structured packings are the packings of choice for applications in severe services subject to fouling, coking, erosion and high solids content, while providing a robust mechanical structure to resist damage during upsets. FLEXIGRID and GLITSCH-GRID structured packings are available in a wide variety of materials. Applications for these packings include Crude Atmospheric and Crude Vacuum Towers, FCC Main Fractionators, Coker Fractionators as well as Ethylene Plant Oil and Water Quench Columns. For further information on FLEXIGRID, GLITSCH-GRID and FLEXIPAC S packings for use in severe service, please ask for brochure KGSS-1.
