Column & Tower Internals - CR3 Group


Operators routinely elect to inspect, clean, replace and even upgrade the mass transfer internals in their columns and towers to satisfy ever-increasing production demands. These internals play an important role in a number of separation and reaction processes on refineries and petrochemical plants and come in a variety of forms for different applications.

In addition to deciding which type of internals to purchase, operators need to ensure the internals are properly installed so they receive the full benefit of the technology, as failure to do so can have a considerable impact on process safety, product quality and return on investment.


We provide the full range of services related to column and tower projects, including removal of internals, cleaning, installation of new or refurbished internals, column inspections, column modifications, and complete project management. To date, we have successfully performed numerous column scopes on refineries and petrochemical facilities across the region and are uniquely positioned as one of the few companies with experience of delivering many simultaneous column jobs on the same complex and across multiple sites and territories at the same time.

Our combination of applying the latest equipment and multi-skilled technicians in a ‘blind to blind’ approach helps to minimise downtime and maximise returns. Pre-engineering services such as planning, scheduling, coordination and logistics are standard practice in every one of our column projects to optimise resources, ensure safe execution and trouble-free start up. All related requirements, such as column decontamination, scaffolding, welding, cold cutting, (including Diamond wire), on-site machining and lifting are handled too. This one-stop approach enables us to take on and execute the total work scope without any interface issues, which improves safety and saves considerable time and cost.


Our comprehensive approach covering all aspects of the work from inspection to installation ensures we deliver optimal safety, quality and schedule efficiency.
Operating under a single project management team, we support our customers with detailed estimates, plans, and procedures for executing any size of project.

Furthermore, our strategic partnerships boost our in-house capabilities, enabling us to provide end-to-end solutions under a single contract, delivering significant savings in the process.
