Tank, Vessel and Column Cleaning
Tank and vessel cleaning by waterjet
The problems caused by build-up of contamination on vessel sides, agitator shafts and blade surfaces can be a major one. Product build up can have a negative impact on plant efficiency, create a risk of downstream contamination and render the mixing equipment difficult to service or repair. Regularly cleaned and maintained vessels can result in faster batch runs and thus greatly improve productivity.
RGL have a wide selection of remotely controlled equipment. This equipment cleans tanks and vessels but keeps the operational staff on the outside, so they do not need to enter these confined spaces. This offers a significant risk reduction to this potentially hazardous task.
A thorough clean to restore efficiency.
Our high pressure (up to 1500bar) water tank cleaning heads rotate on their own axis, equipped with jetting arms which also rotate, ensuring the that the powerful water jets can reach all areas within the vessel.
The equipment is deployed into the vessel through existing access ways or flanged openings. This system cleans all areas of the vessel, even around shafts and seal/bearing housings.
Method
Each tank/vessel clean presents different challenges – whether it’s the size, shape, access, material or environment. However, our method involves deploying a 3D cleaning head system which, due to its unique 360° 3-dimensional rotation, ensures all areas of the surface inside the tank or vessel are reached.
The high or ultra-high pressure pump unit is connected, and the operator controls the system via remote control console.
Any waste created can be collected via vacuum tanker or transferred via our portable vacuum collection system.
Technical advantages
- The cyclic action ensures the water jets hit every part of the internal surface.
- Product removal from behind baffles.
- Coils and paddles are cleaned simultaneously.
- No need to gas free the vessel.
Safety and environmental advantages
Conventional tank and vessel cleaning by men using handheld tools is highly hazardous, slow and ineffective in comparison.
Some previously uncleanable vessels are now possible to undertake quickly and safely using our techniques.
- No confined space entry for men using water jets.
- Effluent is contained and not brought outside the vessel on PPE or through footfall.
- Waste product and cleaning water can be contained, filtered and disposed of in an environmentally friendly manner.
Tank lining removal
Tank linings are usually extremely durable being made of materials such as resins, fibre glass and cementitious mortars. They can be extremely difficult and time consuming to remove using mechanical chipping hammers or abrasive blast cleaning equipment. This gave RGL a reason to develop alternative methods which harness the power of high or ultra- high-pressure water.
We have a range of remotely operated equipment which can remove the bulk of the lining and we finish the difficult to reach areas by hand lance. In each case the surface finish produced by water jetting is often ideal for application of replacement coatings.
