Fineamin – 39

Product Description

FINEAMIN 91  is a highly efficient corrosion and scale inhibitor for open recirculating systems. It is used as a blend, all-in-one product containing polymers, polycarboxilic acid and phosphonic acid.

The product is used in recirculating water systems of refineries and large plants. While, due to its special formula, the blend controls corrosion on metal surfaces, it also cleans and keeps surfaces clean, prevents unplanned downtime and reduces maintenance costs.

Airborne foulants and water caused deposits are also dispersed by this single treatment. Due to the high stability of the phosphates contained in the mixture, the rate of oxidative degradation is low. FINEAMIN 91 does not contain chemical heavy metal ions. It may be used in industrial cooling waters with minimal water disposal problems.

APPLICATION & DOSAGE

FINEAMIN 91 is a cooling water chemical blend added continuously to the recirculating water, directly into the cooling tower.
The maintenance dosage for the cooling water additive is established by our technical team depending on the system parameters. The effect against corrosion can be more efficiently achieved by pre-treating the cooling system with a three times higher quantity than the normal maintenance dosage for a period of seven to ten days.

PACKAGING

FINEAMIN 91  comes in tightly sealed 30kg, 60kg or 210 kg drums. For high-quantity orders of our water treatment chemicals, products are distributed in 1100 kg net IBC containers. Shell life for FINEAMIN 91: 5 years.

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).
