Multi Functional Boiler Treatment
Product code RXSOL-42-5001-025
Highly effective multi-functional liquid reagent for the treatment of steam production systems and heating systems operating on softened water.
Description
Application
The dosage rate is dependent on bioler operating condition, feed 2-3 ltrs of RXSOL-42-5001-025 solution for per thousand ltr of bioler water then control the system by periodic Alkalinity test procedure. If p-Alkalinity is below 200 ppm increase the ratio of RXSOL BWT 5001 solution. If p-Alkalinity is above 400 ppm reduce the concentration of RXSOL-42-5001-025 solution by dilution with water. RXSOL-42-5001-025 is strongly alkaline.RXSOL-42-5001-025 is best applied heat or diluted with any convenient strength on a continuous basis using a suitable chemicals pump. The product should be applied to the boiler feed tank or feed line to ensure adequate mixing.
Precautions
RXSOL-42-5001-025 Boiler Water treatment specialized is a well - balanced blend for boiler water treatment products, Resulting Multi Functional Boiler Treatment including scale and corrosion control by one shot operation. A one-step treatment to control the formation of rust and scale in low pressure and auxillary boilers with working pressure up to 20 bars.
The stability of the added polymers are very useful for water treatment processes. Such polymers with low molecular weights cannot only inhibit calcium, magnesium, and silica scale in cooling towers and boilers, but also help corrosion control by dispersing iron oxide.
Basic Boiler System Schematic
Below is a summary of problems associated with the common impurities in water and solutions to each problem.
List Of Problems Caused By Impurities In Water
Impurity (Chemical Formula)
Problems
Common Chemical Treatment Methods
Alkalinity (HCO3-, CO32- and CaCO3)
Carryover of feedwater into steam, produce CO2 in steam leading to formation of carbonic acid (acid attack)
Neutralizing amines, filming amines, combination of both, and lime-soda.
Hardness (calcium and magnesium salts, CaCO3)
Primary source of scale in heat exchange equipment
Lime softening, phosphate, chelates and polymers
Iron (Fe3+ and Fe2+)
Causes boiler and water line deposits
Phosphate, chelates and polymers
Oxygen (O2)
Corrosion of water lines, boiler, return lines, heat exchanger equipments, etc. (oxygen attack)
Oxygen scavengers, filming amines and deaeration
pH
Corrosion occurs when pH drops below 8.5
pH can be lowered by addition of acids and increased by addition of alkalies
Hydrogen Sulfide (H2S)
Corrosion
Chlorination
Silica (SiO2)
Scale in boilers and cooling water systems
Lime softening
