PunchTech engineers and manufactures liquid distributors, redistributors, collectors, packing supports, bed limiters and associated internals for packed columns and process vessels.
Our approach treats the column internals as an integrated system — connecting liquid distribution, collection, packed-bed support, vapor flow and installation requirements.
Poor liquid distribution, inadequate bed support, vapor obstruction or uncontrolled packing movement can reduce effective mass transfer and create operating problems.
PunchTech reviews the complete internal arrangement rather than any single component in isolation.
Reviewed against
Each internal is reviewed against the packing type, column geometry, process duty and installation requirements.
Introduce liquid across the cross-section of the packed bed. Correct distribution helps minimize:
Header-and-arm arrangements distribute liquid through defined outlets across the column area. The final configuration depends on:
Used between packed beds where liquid needs to be collected and redistributed before entering the next packing section. They can form part of multi-bed packed-column arrangements.
Gather liquid from an upper section while providing a controlled path for vapor flow. Applications may include:
Carry the load of the packed bed while maintaining sufficient open area for gas and liquid flow. Design considerations may include:
Help restrict movement or uplift of packing. Used to counter:
PunchTech can also review requirements for a range of custom and replacement internals:
Products can be manufactured using approved PunchTech engineering, client drawings, EPC drawings or licensor-issued technical packages, depending on the project scope.
Large internals are commonly manufactured in sections to allow movement through vessel manways and assembly inside the column. PunchTech can support:
For existing columns, PunchTech can review:
Send your column layout, process data or existing equipment drawings. PunchTech will review the arrangement and define the engineering and manufacturing scope required.
