Product Description:

It is a well - balanced blend for boiler water treatment products, resulting in a 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. 

Product Application:

The dosage rate is dependent on bioler operating condition, feed 2-3 ltrs of RXSOL-50-5001-025 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-50-5001-025 solution by dilution with water. RXSOL-50-5001-025 is strongly alkaline.RXSOL-50-5001-025  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.
 

CHARACTERISTIC :

  • Convenient liquid treatment, which provides the basic alkalinity on which successful water treatment depends.
  • Provides optimum conditions for hardness control to function.
  • Neutralizes acid conditions.
  • Will assist in keeping silica in suspension.
  • Simple test to determine level of treatment.
  • Can be used in boilers of all pressures.
  • Can be used as a neutralizer after acid cleaning operations
  • Suitable for use with all auxiliary boilers; waste heat units; economizers, package boilers, smoke and water tube boilers.
  • Dispersant action suspends sludge and sediment particles for efficient blow down.
  • Oxygen scavenging for optimum protection.
  • Protects boiler, steam lines, condensate lines and feed water lines from corrosion.
  • Fast action due to catalyst.
  • Simple test to determine level of treatment.
Product Dose:

Control is by simple  boiler water tests or RX CLEANSERS  can provide a suitable test  kits for this purpose.

Used in low pressure and auxillary boilers

:::::::::::::::::::::Alkalinity  TEST FOR BOILER & COOLING WATER ::::::::::::::::::::::::

REAGENT & APPARATUS :
Reagent:  RXSOL TK 7 , TK 8 , TK 9 , . Apparatus : TEST TUBE , Titrator or DROPPER

PROCEDURE for p-ALKALINITY  test ( STEP WISE ):

  1. Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER
  2. Add 1-2 drops of  RXSOL TK7 and mix with the stirring rod , If  sample turns red / PINK ( which indicates presence of p-Alkalinity ) then follows 3rd step otherwise if sample remains colourless ( Record p-Alkalinity = 0 ) .
  3. Add RXSOL TK9  drop by drop ( by counting ) , mixing with the stirring rod until colour just disappears. Each drop is equivalent to 25 ppm of p-Alkalinity , expressed as CaCO3

RESULT  : Each DROPS is equivalent to  25 PPM of Alkalinity .

NOTE :    p-Alkalinity VALUE  =  25 X ( Total Number of DROPS of TK9 , during 3rdstep  )

        

PROCEDURE for p-ALKALINITY  & TOTAL ALKALINITY ( STEP WISE ):

  1. Measure 10 ml of SAMPLE WATER in graduated TEST TUBE / CYLINDER
  2. Add 1-2 drops of  RXSOL TK7 and mix with the stirring rod , If  sample turns red / PINK ( which indicates presence of p-Alkalinity ) then follows 3rd step otherwise if sample remains colourless ( Record p-Alkalinity = 0 ) then proceed to STEP- 4.
  3. Add RXSOL TK9  drop by drop ( by counting ) , mixing with the stirring rod until colour just disappears. Each drop is equivalent to 15 ppm of p-Alkalinity , expressed as CaCO3
  4. Add 2-3 drops of RXSOL TK8 and mix with stirring rod , the sample will turn to BLUISH-GREEN .
  5. AddRXSOL TK9 carefully by counting drop by drop and mixing throughly until a light reddish  pink  colour develop.

RESULT  : Each DROPS is equivalent to 25 PPM of Alkalinity .

NOTE :    p-Alkalinity ppm CaCO3VALUE ( A )  =  25 X ( Total Number of DROPS of TK9 , during 3rdstep  )

Total Alkalinity ppm CaCO3VALUE  =  A +  { 25 X ( Total Number of DROPS of TK9 , during 5th step  )}

 

 

 

NUMBER OF DROPS OF TK9                                                                                     p-Alkalinity as CaCO3                                

                        1 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>25
                        2 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>50

                        3 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>  75
                        4 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>  100

                        5 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> > 125

                       30>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> >750

                       40 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>  1000
 

Optimum Result    :   p-Alkalinity  level  is between 100 to  150 PPM is suggested.

 if  p-Alkalinity level is more then 150 ppm then level should be reduced by increased BLOW DOWN process with immediate effect.   

For Below  50 ppm  , Dose ½ Ltrs of RXSOL-50-5001-025 for 1000 Ltrs of  BOILER WATER , to maintain p-Alkalinity level 100 ppm.

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
