Cooling Water Systems Solutions
Cooling water imposes numerous challenges in the operation of industrial facilities and its quality is subject to always keeping track of and controlling of major issues like corrosion, biological contamination (microorganisms like bacteria, algae, fungus etc), fouling and scale.
Under these difficult conditions, the water quality in cooling towers determines the reliability of the facility and the lifetime of the equipment: towers, piping, heat exchangers.
An appropriate water treatment solution for cooling towers is needed in refineries, petrochemical facilities, paper and timber industry, pharmacy, food industry, air conditioning technology, construction and many others.
In most cases, film-forming amines based treatment is a sufficient and environmentally friendly alternative to conventional anti-corrosion water treatment methods like hydrazine. Its action is manifested through the creation of a microscopic, hydrophobic film on the metallic surface, by using polyamines, which are naturally connecting to loose nitrogen atoms present in the metal. This prevents oxygen to attack the metallic surfaces, while improving the heat transfer.
Regarding the particular case of cooling systems and their harsh operational conditions, the polyamines represent the anticorrosion solution as one of the components of a more complex water treatment program. Used along with biodispersants, phosphonates and co-polymers, polyamines (FINEAMIN 06) are increasing their effect and protecting the whole system against corrosion and future deposits by forming a barrier between the metal and the water carrying all kinds of contaminants.
Hot, humid and overcrowded with nutrient substances, cooling towers are the ideal environment for unwanted biological growth. Microorganisms such as algae, bacteria, fungi that enter the system through the water supply or by the the air drawn through the tower, contribute to the formation of a biofilm on all surfaces reducing thermal efficiency.
Controlling and preventing such kind of biological accumulation can be done by using FINEAMIN biocides injected as shock treatments, along with biodispersants, surfactant, non-ionic products that eliminate the already existing bio deposits.
Build up of minerals in the cooling tower water and pipes clogging with debris and dirt are two of the main things that affect heat exchange surfaces and prevent the even distribution of water through out the cooling system increasing operational costs.
Crystal formation and deposits can be inhibited by hardness stabilizers (FINEAMIN 91), mixtures of polymers and copolymers, phosphonates and copper inhibitors that modify crystal growth by disturbing the nucleation process. Deposits are blocked and the modified crystals prevented from sticking to each other and metal surfaces. These products are used together with biodispersants and alkalizing amines (FINEAMIN 06).
