Column & Tower Internals
Maintenance of Columns:
Column & tower refer to an essential equipment used for various separation processes.
The main types of columns used in oil refineries and petrochemical industries:
- Distillation columns
- Fractionating columns
- Stripping columns.
Hurdles during operation:
Sometimes during heavy operation, the internal elements of the columns & towers tends to deform and loosen out of their position, due to which proper separation of process chemicals weakens leading to a trimmed production volume for which removal and replacement of the internal elements are must. Schedule overhauling and maintenance is planned which ultimately contribute to intensify and escalate the performance of the equipment.
What we offer:
We provide a wide range of services for the maintenance of column & towers and its internals which includes,
- Complete installation of Column internals
- Column and tower inspection
- Removal of column and tower internals
- Cleaning of column and tower internals
- Internal repairs to columns and towers
- Installation of all types of column and tower internals including structured packing, random packing, trays, and down comers.
- Confined space scaffolding erection and dismantling
- Column and tower modifications
- Column nozzle modification with associated piping re-routing and replacement.
- TSR Repair / Modifications
- Laser Alignment of column tray.
- Completer Column / Tower replacement.
With a team of experienced people, we offer edge to edge service which includes proper understanding and estimating the overall job with real and proper planning, effective and healthy coordination with our end user which helps us to recognize the critical path and abating the overall duration of the job by reducing the repetition of work. All related requirements, such as column decontamination, scaffolding, welding, cold cutting, (including Diamond wire), on-site machining and lifting are handled too.
