Engineering Design and Manufacture of Column Tray

Distillation Trays
Distillation trays play an essential part in mass transfer technology of hydrocarbon, chemical industry and other related industries. Years of accumulated extensive experience combines with steady development let to industry standard tray and patented tray designs which shape Saiptech a top manufacturer of trays. Apart from a comprehensive range of products, Saiptech also provides its flexibility and competence by tailored designs adapted to the unique need of clients.

Trays in Saiptech are designed using its in house programs, which give a full hydraulic output for the individual cases considered. The final design is optimized from both a cost and operational point of view. The optimum style of valves, from a venture cage valve for a low pressure drop to a min fixed valve for maximum performance, can be specified by our experienced design engineers.
Supply of new trays for new construct column
Saiptech has extensive experience in the supply of trays with a full hydraulic design for brand new columns. We take extra care in the layout and the design of the vapour and liquid inlets to ensure that maximum performance is achieved.
The internal arrangements are considered carefully to ensure full compliance with the required specifications as well as a design that is reasonable to install. Special consideration may also be given to the tray design to allow for a reduced onsite installation period.


Replacement of existing trays on a like for like basis
Saiptech can supply a partial or full replacement of existing distillation trays. This usually occurs during routine maintenance. We supply Saiptech designed trays that fit up to existing support structures and operate identically to the previous equipment.
We offer equivalent valve and identical downcomer sizing to ensure identical column operation. Our commitment also extends to the emergency situation where, as a result of an unscheduled breakdown, replacement trays can be drawn and manufactured in a very short time frame.
Our experienced draftsman are experts at taking a theoretical design and developing a full three dimensional model. This model ensures that there are no conflicts when the equipment is installed.

Upgrading existing columns for new operating conditions
Old columns need to be upgraded for new flow conditions. We have developed systems that allow for the modification of downcomer sizes and overall tray dimensions without the need for hot modification of the existing vessel welded in attachments.
This allows for lower cost and reduced time vessel revamps.
Higher capacity tray designs can also lead to column upgrades in performance without expensive column replacement.
