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 Trays

Sieve Trays

Conventional 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 Trays

Bubble Cap Trays

Bubble 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 Trays

Dual Flow Trays

Counterflow 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 Trays

Valve Trays

GTI 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 Trays

Baffle Trays

These 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.
