Rohrer Group not only specialises in protective coating works but also in chemical cleaning and degassing of chemical and petrochemical plants, refineries, and tank farms.

Chemical cleaning

The chemical cleaning phase is preceded by an analysis in a laboratory in order to define the use and composition of the necessary additives. After that, the right cleaning method is chosen according to the type of plant unit to be cleaned, the operational conditions, and the contamination level, e.g. buoyancy method, countercurrent method, cascade method, or circulatory method. After the chemical cleaning, the residues are neutralised and disposed of duly.

Thanks to our efficient methods in conjunction with specific cleaning additives and the know-how of our staff, we can handle any task.

Benefits of chemical cleaning:

• Realisation of highest cleaning levels
• Lower energy consumption after cleaning
• Reduction of running costs
• Prolongation of product life
• Reduction of costs and saving of time as there is no need for time-consuming dismounting and scaffolding compared to traditional cleaning methods
