The patented technologies used in SUPERFRAC > Trays (Figure1) are the culmination of over twenty years of comprehensive tray development work.The unique combination of SUPERFRACpatented technologies and design strategies produces the highcapacity and the maximum vapor/liquid contact efficiency achievable on a cross-flow distillation tray as shown in Figure 2.As a result,the SUPERFRAC tray gives the highest economic benefit to operators of distillation columns seeking solutions forboth new construction and revamp projects.A well-designed conventional tray generally provides the mosteconomically...

A thorough understanding of downcomer flooding mechanisms in a wide variety of services is critical to successful application of high performance tray technology.Advanced downcomer technology developed by Koch-Glitsch provides the capability to accurately size and shape the downcomer,which provides the following benefits:Conventional downcomers for standard tray construction and simple installationՕTruncated downcomers to maximize active area for vapor-liquid contact Multi-chordal side downcomer skirts for longer flowpath length and greater efficiency ՕMulti-stage downcomers for additional liquid-handling...

For moderate fouling systems,large diameter fixed valves,such asthe VG-10 (Figure 5),or the patented For extreme fouling services,Koch-Glitsch offers PROVALVE > unit (Figure 6) can be used on several SUPERFRAC configurations toreduce the tendency to foul. SUPERFLUX > ή Trays,which can employ many of the capacityand efficiency features of SUPERFRAC trays.SUPERFLUX trays are designed toincrease run time in fouling applications.Koch-Glitsch can address the specific fouling characteristics present in your operation with our proprietary technology offered on SUPERFLUX trays.The PURGE Downcomer (Figure...

OMNI-FIT technology is a set of mechanical engineeringdesigns used to reduce the cost and downtime of revamps.These technologies include expansion rings, pedestal supports,downcomer adapters,and innovativetray designs that can minimize or eliminate welding onan existing tower.Efficiency and capacity enhancements can be achieved by using OMNI-FIT technology for yournext turnaround project.OMNI-FIT technology can be used to: Increase theoretical stages Change tray spacings > Change the number of passes Modify downcomer sizes or configurations Install multi-pass SUPERFRAC trays Change tray orientation...

HORIZON technology is a set of mechanical construction techniques developed specifically for in-shop installation of trays with the vessel in the horizontal position.Using the patented FLEXILOCK tray construction as its primary building block,this special mechanical design prevents the problems that can occur when conventionally designed trays are installed with the vessel in the horizontal position.These problems include inefficient installation sequencing,part deforming/breaking,panel shifting,joint dislodging,extra field inspecting and field readjusting of tray parts.If you plan to shop-install...

Obtaining desired tower performancerequires the proper handling of liquid and vapor entering the column.The types of feeds or inlets into a column can generally be classified into three major categories:Liquid only (contains less than 1% of vapor by volume)ՕMixed liquid and vapor,flashing orsuppressed flashVaporThe selection criteria for each category offeed device is unique > Among the factors Koch-Glitsch considers in designing a liquid feed device are:ՕType of tray Expected tray performance ՕFlow rateOperating rangeՕDegree of sub-cooled liquid Requirements for mixing The feed arrangement for...
