Tank & Vessel Cleaning

Overview

As any producer of chemical products will be aware, the problems caused by build up of contamination on vessel sides, agitator shafts and blade surfaces can be a major one. Product build up results in commercial inefficiencies, the risk of downstream contamination and the mixing equipment becoming impossible, to service or repair. Damage to components can occur when the disassembly of contaminated shafts and bearing housings is attempted.

RGL are able to clean tanks and vessels from outside without the need to send operatives into these confined spaces. This offers a huge risk reduction to this previously high hazard task. Regularly cleaned and maintained vessels result in faster batch runs, lower plant operating costs, less downtime due to downstream contamination and thus greatly improved productivity.

Our high pressure (up to 1500bar) water tank cleaning heads rotate on two axis, thereby reaching all areas within the vessel. Our advanced nozzle positioning technology ensures that the water jet is focused therefore becoming a most effective cleaning and cutting tool. The equipment is deployed into the vessel through existing access ways or flanged nozzles. This system cleans all areas of the vessel, even around shafts and seal/bearing housings.

We also offer tank lining removal and gas tight cleaning solutions for vessels (see below).

  • The cyclic action ensures the water jets hit every part of the internal surface.
  • Speed of rotation and position of nozzle are adjustable.
  • Product removal from behind baffles.
  • Positioning systems are used to access the shadow areas where possible.
  • Coils and paddles can be perfectly cleaned.
  • No need to gas free the vessel.
  • No need to remove mixer paddles, shafts or agitators.
  • Nozzle may be positioned at bottom of vessel to remove product from drain point.
  • No confined space entry for men using water jets.
  • Effluent is contained and not brought outside the vessel on PPE.

RGL has many years experience in high pressure tank and vessel cleaning. We operate in a wide range of commercial and industrial environments, from chemical plants to oil refineries, and food factories to paint manufacturers. Some of the work we carry out includes:

  • Styrene tanks.
  • Resin tanks and blenders.
  • Cleaning build up on mixers and agitators.
  • Cleaning behind baffles and cooling coils.
  • GRP lining removal from tank floors and walls.
  • Rubber and other similar products removed from cooling coils.
  • Solid polyester resin removal from vessel with mixer and heating coils.
  • Paint removal.
  • Tank lining removal:
    Tank linings are usually extremely durable, made of materials such as epoxy resins, glass reinforced products and cementitious mortars. They can be extremely difficult to remove using mechanical chipping hammers or abrasive blast cleaning equipment. We have developed remote control, semi-automatic equipment that deploys a UHP water jet into the tank. This equipment is capable of removing these coatings from floors, walls and columns quickly and safely. The surface finish produced by water jetting is often ideal for application of replacement coatings.
  • Gas tight systems
    In some situations it is critical that gases from inside the vessel are contained, either due to the risk of explosion or because the gasses may be hazardous to health. We are now able to offer reactor cleaning systems that are certified to ATEX 2T3 standards. Furthermore, our water jetting units are fitted with spark arrestors and Chalwyn valves making them safe to use in chemical plants and other hazardous environments.
    We have an impressive success record, having achieved perfect results in previously uncleanable vessels.

Each tank/vessel clean presents different challenges – whether it’s the size, shape, access, material or environment. The method involves deploying semi-automatic nozzle positioning devices into the tank or vessel. The device uses a 3D cleaning head system which, due to its unique 360° 3 dimensional rotation, ensures all areas of the surface are reached.

The high or ultra high pressure pump unit is connected and the operator controls the system via remote control console.

Waste steams can be collected via vacuum tanker or transferred via our portable vacuum collection system.

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.
