Evaporator Treat-51

Procedure-of-use: The most effective descaling is accomplished by circulation.In the case of small components,the soak method in an immersion bath can be used. If the equipment to be cleaned is contaminated by oil, grease or sludge, then pre-cleaning with DEGREASER ( RXSOL OB 1005 ) is necessary. Depending on the extent of scaling, use a solution of 2.5-10% RXSOL-54-1008-025 . The solution will have a red colour which changes to orange when 85% of the acid has been neutralized , & to colourless  when the solution is totally neutralized. Whenever possible, the solution should be heated to 60°C.Neutralised  solutions can be re-activated by adding more RXSOL-54-1008-025  until the red colour reappears. 

Fields: Descaling of  Boilers, Descaling  of Diesel Engine Cooling Systems, Condenser, Pipeline collection system, Evaporators, Calorifiers, Heat Exchangers,The strength of the acid can be enhanced by adding 1part sodium chloride (common salt) to 20 parts of Descalex.If salt is not available, an acceptable alternative is to dissolve RXSOL-54-1008-025  in sea water. After use of RXSOL-54-1008-025  a  0.5% solution of Alkalinity Control in fresh  water should be used for neutralization.

RXSOL-54-1048-020 should not be used on Aluminium, Zinc, Tin, or any Galvanized Surfaces for which a special grade cleaner should be used. Chemical Cleaning Module RX cleansers has developed a 280 litres capacity cleaning module, primarily designed for use with chemical acid solvents for descaling boilers, calorifiers, heat exchangers & other types of equipment where rust & scale form RXSOL-11-1008--DC Boilers, See RX cleansers Practical Application Manual

Air Cooler Cleaner Sea Water Side Scale Remover manufacturer and supplier Exporter.

Dirt in tubes of seawater side

White scales attached on the seawater side of air coolers of many vessels. We found that in most cases, the main component of the scales is calcium carbonate and there is also a small amount of calcium sulfate. Therefore in most cases, if you dissolve the calcium carbonate the scales will be removed.

However, if the amount of scales is large enough to block the tube, the cylindrical scale will usually have calcium carbonate on the outside (the side that is in contact with tube) and calcium sulfate in the center (part that seawater passes through). Calcium sulfate is easier to be formed when the temperature goes higher.

When the amount of scales increases, the contact area of scale and cleaner is very small and a longer time of dissolution is required. Calcium sulfate cannot be dissolved by an acid cleaner.

RXSOL-54-1048-020 is a powerful dissolving agent of calcium carbonate. Therefore, it is better to use RXSOL-54-1048-020  to do circulating cleaning at an early stage before the scales build up and block the tube, or regular cleaning is recommended as well. It is impossible to do a circulating cleaning when the tube is completely blocked.

while Dirt attached on air-side fins of air coolers are a mix of carbonaceous particles such as soot and oil mist of unburned fuel components can be clean by RXSOL-16-0009-025. ( www.rxmarine.com/air-cooler-cleaner-25-ltr )
Carbonaceous particles can be removed by alkaline cleaners and oil mist can be removed by oil based cleaners. However, it is very difficult to remove the mix of these substances. If you use an alkaline cleaner, oil will repel the water based alkaline cleaner; if you use oil based cleaner, carbonaceous particles will get in the way and stop oil from being removed.

This cleaners designed to remove both carbonaceous and oil simultaneously. An effective cleaning method is to immerse one side to remove the loose stains first, and then immerse the other side. This method can efficiently remove dirt and prevent swollen dirt peeled from fins from blocking the spaces between fins.

Also Suitable for Cleaning of BOILER and Cooling Water deposition...

Testing control procedure

1. Test water sample from the water boiler as described in the direction of the  Alkalinity Test Kit ( p & m Total ) http://www.rxmarine.com/Alkalinity-test-kit
2. Determine the present alkalinity value expressed as ppm CaCO₃ .
3. Desired level of 100-150 ppm as CaCO₃.
4. A control test for the alkalinity  of the water should be conducted after 3- 6 hours from the application.
5.  

Mechanism: It converts calcium hardness into soft, non-adherent sludge that is easily removed by blowdown.

The presence of alkalinity in a water sample may be due to many different substances.  However, for the sake of simplicity, the presence of bicarbonate, carbonate, and hydroxide ions is commonly considered as alkalinity.  The points of change in colour of phenolphthalein and methyl orange indicators, which occur at pH 8.3 and pH 4.3 provide standard reference points which are almost universally used to express alkalinity.

Very high alkalinity values can be undesirable in an industrial water supply.  For example, the presence of a high methyl orange alkalinity should be avoided in boiler feed water because of the resultant carbon dioxide content of the steam.  Carbon dioxide usually is responsible for the corrosion of steam and return lines.  High boiler water alkalinities are also undesirable because the presence of high hydroxide ion concentration is the primary cause of caustic metal embrittlement. A very high boiler alkalinity can also lead to an undesirable carryover condition.  On the other hand, the alkalinity of boiler water must be sufficiently high to protect the boiler metal against acidic corrosion and to ensure precipitation of scale-forming salts.  Usual treatment approaches include setting both a minimum alkalinity level and an operating range.
 

Hydroxide alkalinity may be determined by adding barium chloride prior to titration to precipitate the carbonate ion from solution, allowing direct titration of the hydroxide alkalinity.  Measurement of hydroxide alkalinity is also used to control lime soda softeners.
 

In cooling water systems, alkalinity is of major importance since the total alkalinity of a water is one factor that must be considered when predicting the tendency for the water to precipitate calcium carbonate scale.  Depending on the choice of chemical treatments to protect against corrosion and scale formation, the operating alkalinity and pH ranges are chosen to balance these two features.

Alkalinity Titrimetric Method (0-200 ppm) 

Principle Theory

This test is based on the determination of alkalinity by titration with standard acid to the phenolphthalein colour change (or to a pH of 8.3) and to the methyl orange colour change (or a pH of 4.3).  For determination of hydroxide alkalinity only, barium chloride is added prior to titration to precipitate the carbonate ions.  Titration is then taken only to the phenolphthalein endpoint.  A pH meter may be used instead of the indicators to determine the endpoints of the titration.
