APPLICATION & USE

FERRO IOD CLEAN is an effective cleaner for removing iron oxides without the need for neutralization. Using good quality fresh water, circulate a maximum 10% solution of FERRO iod CLEAN through the equipment. Depending upon the extent of the fouling, the solution strength, contact time, and  temperature may have to be adjusted. Elevated temperatures will improve the cleaning process. In the event of a heavily fouled cooling water system, more than one cleaning may be required.
After the cleaning process has been completed using FERRO IOD CLEAN, the system should be drained and thoroughly flushed with fresh water. A quality corrosion inhibitor,such as RXSOL-40-4001-025 or RXSOL-40-4010-025 should then be immediately used to protect the system.

For a precommissioning cleaning to remove iron oxides, circulate a solution of 3-5% FERRO IOD CLEAN through the equipment. If cleaning is to be performed without heat, circulate for several days, depending on the severity of the deposits. If heat, 49-65° C, is applied, then circulation can be reduced to less than a day, again, depending on the severity of the deposits. For a precommissioning cleaning to remove iron oxides from a boiler that has not been coated with a protective grease, circulate a 3% solution of FERRO IOD CLEAN through the system for 24 hours at 70° C. After cleaning and fresh water
flushing, complete final fresh water flush with a 1% solution RXSOL-50-5002-025 to reduce flash rust.

The following supplies are required to perform the cleaning procedure described below (Diesel Engine Cooling Systems (Out of Service)):
 

1.  Circulating pump - either electric or air-driven, which would be capable of circulating the water system 1-2 times per hour.
2. Mixing tank. An open end, 100-liter drum, such as Air Diaphragm Pump System  is suitable.
3. Steel piping, flexible hoses, fittings and valves as required to perform the job.IMPORTANT: This should include a vent pipe leading from the top of the engine system to an upper deck area outside of the engine room.
4. Protective clothing for personnel. This includes goggles, rubber gloves, rubber aprons, etc.
5. Sufficient FERRO IOD CLEAN to prepare the required cleaning solution (maximum 10% dilution) based on the normal water capacity of the system being cleaned.

Cleaning Diesel Engine Cooling Systems (Out of Service)
 

1. Where possible, connect the discharge side of the circulating pump to the lowest practical point on the diesel cooling system using a length of flexible hose and the appropriate fittings. Using a second section of flexible hose with fittings, connect a cleaning solution return with a valve from the highest point on the cooling jacket system to the top of the mixing tank, which is the suction supply for the circulating pump.
2. Add approximately 100 liters of fresh water to the tank.
3. Before commencing the cleaning, heat the water in the cooling system until it reaches a temperature of 60-82° C. The heat can be provided by a heating coil or steam line in the cleaning solution mixing tank or a system heat exchanger.
4. Secure the engine. This only applies if the engine had to be run to heat the water.
5. Be sure all valves in the mixing tank, pump, return and vent system are open. Start the chemical circulating pump and adjust the flow rate so that the level of the solution in the mixing
   tank remains constant.
6. Add sufficient FERROCLEAN to the mixing tank to prepare the required proportions of cleaning solution based on the
   water volume in the system. An equal amount of water will need to be drained from the system before adding FERRO IOD CLEAN.
7. Continue circulation and maintain the cleaning solution temperature for a minimum of 12 hours. As the cleaning progresses the system water may start to change to a dark green/black color.
8. Drain and flush the system with fresh water. Continue flushing the system with fresh water until the discharge water is completely clear.
9. Inspect the cooling system interior for cleanliness. Repeat the procedures if the system is not completely clean.
10. Disconnect the vent system and the cleaning system from the engine. Secure all inlet and outlet cleaning points.
11. Fill the engine system with distillate or good quality fresh water and add the correct amount of corrosion inhibitor prior to returning the equipment to service.

Hydrogen Sulfide Scavenger is works as a corrosive Acidic GAS Remover from system as well as from working station. which is not only damaging precious instrument but also creating Worker Health  problem by attacking on respiratory system.

The neutralizing effect of H2S is the result of a simple chemical reaction between the components of an RXSOL-11-5014-210 molecule and an offensive, toxic odour molecule. 

       Hydrogen Sulfide (H2S) + RXSOL-11-5014-210  =  Bi Sulfide salt
       
The resultant products in the above equations are safe and stabilized compounds, which are neutral, harmless, and odour free. They dissolve in water and will not be re-released into the atmosphere in normal conditions.

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

:::::::::::::::::::::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 3^rd 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 3^rdstep  )

Dosage:
The amount of Closed Loop Biocide required to inhibit or remove bio fouling depends on the type of system, application, re-circulating fluid property and plant operating conditions. The specific dosage rates will be specified by the CSL technical representative.
