Tray Technology
GTI Solutions offers a full range of tray products and services to serve the refining, chemical, and petrochemical industries. These products will vary from industry standard valve and sieve trays to a variety of high performance trays.
Our team of experts have extensive experience in a wide range of mass transfer applications and can provide innovation solutions to the most challenging separation requirements. Whether you require exotic metals hardware replacements during a turnaround or reconfiguring the process scheme for process optimization and energy savings, we offer a single solution window to advise and implement mass transfer equipment solutions. Our portfolio of tray products include:
Conventional Trays
G-HPT™ High Performance Tray Technology
GTI Solutions offers a variety of high performance trays and active devices to maximize the capacity and efficiency of your distillation equipment.
G-MxPush™ High Performance Trays
G-MxPush are designed to reduce liquid gradient across the tray deck and provide uniform vapor distribution. These trays are generally used in pumparound circuits and/or other high liquid load services.
G-MxMD™ High Performance Trays
G-MxMD is a cross-flow multiple downcomer tray. It features high capacities with better efficiencies than conventional multiple downcomers trays. The resulting low weir load with reduced downcomer back-up and froth height allows for a smaller column diameter than would be achievable with conventional trays.
 Sieve TraysConventional Cross flow trays with a simple perforated deck available with a variety of holes sizes and designs. They are limited in turndown and have been largely replaced by valve trays or fixed valve trays. |  Bubble Cap TraysBubble cap trays are used when high turndown is required or when very low leakage is allowed. A reliable but ultimately expensive design; bubble cap trays are still used in the industry today with specific applications. |  Dual Flow TraysCounterflow trays without downcomers, the tower cross sectional area is completely made up of perforated plate. They are used in fouling applications and offer a limited operating range. |
|---|---|---|
 Valve TraysGTI Solutions offers a wide variety of valve trays both in movable and fixed construction for new installations, revamps, and replacement of existing equipment. The G-V1™ valve is the industry standard workhorse valve that has largely replaced sieve or bubble cap trays in most applications. The G-C1™ is a caged version that provides better reliability while the G-BD1™ valve is the industry standard rectangular valves. |  Baffle TraysThese trays are typically available in side to side and disc and donut variations. They offer high fouling resistance with low efficiency. Typically used in fouling and/or heat transfer applications where efficiency is not a concern. |
GTI Solutions has developed a wide range of valve types and features known as G-HPT™ to enhance the vapor and liquid contacting, or mass transfer, that take place on a tray deck.
The G-mF1 valve is a miniature fixed valve punched from the tray deck while the G-pF1 valve is a high performance directional valve used to improve the flow of fluid across the tray deck.
The G-sF2 valve is snap-in fixed valve installed on the tray deck with a high net rise to resist fouling. It features a proprietary downcomer configuration to improve column performance.
High Performance Valves
G-Frac™ High Performance Trays
G-Frac is a high performance cross-flow tray that use tray deck enhancement along with improved downcomer technology to achieve additional 20 ~ 30% capacity with same or higher tray efficiency when compared to conventional valve trays.
