Chemical cleanings of plant parts are always necessary when the heat transfer surfaces are contaminated and consequently the cooling or heating of a process is not ensured anymore, or the flow of a liquid medium is hindered when tubes and other parts of a plant are blocked. Such plant parts are e.g. boilers, cooling towers and water pipings where disturbing losses of pressure occur. The reason for such contaminations can be precipitations of suspended solids (exceeding of the solubility product), adherence of washed out solid matter (fouling), formation of corrosion products, adherence of microorganisms (biofouling), as well as fats, oils or other organic substances, e.g. Drilling and grinding emulsions, corrosion protection and cooling lubricants etc. There is no universal agent for the quick removal of contamination. Some can be removed well with alkaline agents, others better in the acidic range, and depending on the system, material incompatibilities have to be considered. The large number of conceivable cleaning problems makes detailed advice before the start of cleaning useful.
