PunchTech provides engineering and design support for mass transfer equipment, column internals, replacement projects and process-industry applications.
We connect process requirements, mechanical design, manufacturing feasibility and installation planning to develop equipment that is practical to manufacture, inspect and install.
The performance of trays, packing and column internals depends on more than individual component design. Process duty, hydraulic loading, vessel geometry, internal configuration, material selection, fabrication and installation must work together.
PunchTech supports EPC contractors, equipment manufacturers, engineering consultants and plant teams through the technical stages required to define a responsible manufacturing scope.
Our engineering involvement is established project by project based on the available process data, client drawings, technical specifications and required deliverables.
For applicable projects, PunchTech reviews the available process basis and hydraulic requirements to support the selection and configuration of trays, packing and associated internals. The review may consider:
The final engineering scope, calculations and performance responsibilities are defined during technical review.
Column internals must operate together. The performance of packing can be affected by liquid distribution, vapor flow, collection, support, sealing and installation accuracy. PunchTech can support the selection and arrangement of:
Each configuration is reviewed against the vessel geometry, packing system, process duty, access limitations and approved project requirements.
PunchTech supports new equipment, replacement requirements and revamp projects involving tower trays, structured packing and random packing.
Engineering review may cover tray type, tray spacing, active area, downcomer arrangement, weir configuration, segmentation and mechanical installation requirements.
Engineering considerations may include packing geometry, required bed height, pressure-drop limitations, liquid distribution and associated support and hold-down systems.
Selection may consider packing type, size, material, bed depth, pressure drop, fouling conditions and the required distributor and support arrangement.
Product-specific performance claims are finalized only against the approved engineering basis and agreed project scope.
PunchTech develops manufacturing and assembly information based on approved engineering inputs. Clear detailing helps reduce ambiguity during fabrication, inspection, assembly and site installation. Deliverables may include:
A technically correct design must also be practical to manufacture, inspect, transport and install. Before production release, PunchTech reviews the design for:
Identifying these requirements before manufacturing helps reduce avoidable changes, delays and installation difficulties.
Brownfield and replacement projects often begin with incomplete drawings, limited site information or obsolete equipment. PunchTech can review available drawings, field dimensions, photographs, samples and existing equipment details to define the scope.
Large column internals are often manufactured in segments for transportation through vessel manways and final assembly inside the equipment. PunchTech can incorporate installation considerations into the engineering and detailing process, including:
PunchTech works with EPC contractors, OEMs, consultants and procurement teams requiring structured technical communication and clearly defined project deliverables. Our objective is to provide a clear connection between engineering intent and manufacturing execution.
The information required depends on the product and project stage. Where available, please provide:
Where the technical information is incomplete, PunchTech will identify the minimum inputs needed to progress the review.
Supporting mass transfer and column-internal requirements across refinery, petrochemical, fertilizer and chemical applications.
Engineering, manufacturing, inspection and installation considerations managed within one project workflow.
Designs reviewed for practical production, segmentation, assembly and site installation.
Support for existing equipment, incomplete drawings, field information and shutdown requirements.
Structured technical communication for EPCs, OEMs and international procurement teams.
The engineering scope is defined around the actual process requirement, technical package and commercial responsibility.
Share the available process data, column layout, drawings or equipment details. Our team will review the information and define the engineering inputs required for the next stage.
