SUPERFRAC® high performance trays
The SUPERFRAC® tray is a high-performance cross-flow tray that has the highest combined capacity and efficiency of all cross-flow trays tested at FRI.

SUPERFRAC trays can be used in new construction and revamp opportunities for virtually any service in which conventional sieve and valve trays are used. They are especially beneficial in applications requiring a large number of mass transfer stages or where mass transfer efficiency is critical to the economics of the operation. Examples include superfractionators (ethylene, propylene), light hydrocarbon fractionators, splitters in chemical and petrochemical applications, and aromatic services.

Valve types

Koch-Glitsch has developed a variety of valve styles to enhance the vapor-liquid contacting that takes place on a tray deck.

MINIVALVE® tray decks use smaller-size valves that provide reduced entrainment and better efficiency than conventional valve and sieve trays.

Tray enhancements
 
The patented technologies used in SUPERFRAC® trays are the culmination of over twenty years of comprehensive tray development work. The unique combination of SUPERFRAC patented technologies and design strategies produces the high capacity and the maximum vapor/liquid contact efficiency achievable on a cross-flow distillation tray. As a result, the SUPERFRAC tray gives the highest economic benefit to operators of distillation columns seeking solutions for both new construction and revamp projects.
 
Koch-Glitsch targeted three major areas for enhancing the performance of conventional trays:
  • Advanced downcomer technology
  • Active area enhancements
  • Inlet area enhancements
