Directions for use
This product is formulated for use in conjunction.Oxygen Scavenger Plus can be used in any boiler system, and in conjunction with mechanical deaeration systems. Removal of dissolved oxygen is vital for prevention of corrosion and especially pitting corrosion in boilers. When dosed into a boiler system, Oxygen Scavenger Plus will react with dissolved oxygen and form non corrosive compounds. The product is volatile, and left over product from oxygen scavenging in the pre-boiler section will evaporate and assist protection of the steam and condensate system. No solid materials are produced when using Oxygen Scavenger Plus.
Dosing method
Rx Marine International recommends continuously into the boiler feed line and Boiler Water Treatment Dosing Unit.
Dosing should be controlled so that the DEHA residual in the condensate is between 0.08-0,30 ppm. The consumption will depend on feed water temperature and the amount of water fed into the boiler. For more information about initial dosage and dose rate please consult your nearest Customer Centre.

Sampling and testing
A representative sample of Condensate should be drawn for analysis daily. The sample should always be taken from the same sampling point, cooled and tested immediately By Rxsol Test Kit. It is important that regular testing is carried out, to ensure the correct level of treatment is maintained.

The establishment of protective metal oxide lay-ers through the use of reducing agents (such as hydrazine, hydroquinone, and other oxygen scavengers) is known as metal passivation or metal conditioning. Although "metal passivation" refers to the direct reaction of the compound with the metal oxide and "metal conditioning" more broadly refers to the promotion of a protective surface, the two terms are frequently used interchangeably.
The reaction of hydrazine and hydroquinone, which leads to the passivation of iron-based metals, proceeds according to the following reactions:
| N2H4 | + | 6Fe2O3 | ® | 4Fe3O4 | + | 2H2O | + | N2 |
| hydrazine | hematite | magnetite | water | nitrogen |
| C6H4(OH)2 | + | 3Fe2O3 | ® | 2Fe3O4 | + | C6H4O2 | + | H2O |
| hydroquinone | hematite | magnetite | benzoquinone | water |
Similar reactions occur with copper-based metals:
| N2H4 | + | 4CuO | ® | 2Cu2O | + | 2H2O | + | N2 |
| hydrazine | cupric oxide | cuprous oxide | water | nitrogen |
| C6H6O2 | + | 2CuO | ® | Cu2O | + | C6H4O2 | + | H2O |
| hydroquinone | cupric oxide | cuprous oxide | benzoquinone | water |
Magnetite and cuprous oxide form protective films on the metal surface. Because these oxides are formed under reducing conditions, removal of the dissolved oxygen from boiler feedwater and condensate promotes their formation. The effective application of oxygen scavengers indirectly leads to passivated metal surfaces and less metal oxide transport to the boiler whether or not the scavenger reacts directly with the metal surface.

pH Control
Maintenance of proper pH throughout the boiler feedwater, boiler, and condensate systems is essential for corrosion control. Most low-pressure boiler system operators monitor boiler water alkalinity because it correlates very closely with pH, while most feedwater, condensate, and high-pressure boiler water requires direct monitoring of pH. Control of pH is important for the following reasons:
The pH or alkalinity level maintained in a boiler system depends on many factors, such as sys-tem pressure, system metals, feedwater quality, and type of chemical treatment applied.
The corrosion rate of carbon steel at feedwater temperatures approaches a minimum value in the pH range of 9.2-9.6 . It is important to monitor the feedwater system for corrosion by means of iron and copper testing. For systems with sodium zeolite or hot lime softened makeup, pH adjustment may not be necessary. In systems that use deionized water makeup, small amounts of caustic soda or neutralizing amines, such as morpholine and cyclohexylamine, can be used.
In the boiler, either high or low pH increases the corrosion rates of mild steelThe pH or alkalinity that is maintained depends on the pressure, makeup water characteristics, chemical treatment, and other factors specific to the system.
The best pH for protection of copper alloys is somewhat lower than the optimum level for carbon steel. For systems that contain both metals, the condensate and feedwater pH is often maintained between 8.8 and 9.2 for corrosion protection of both metals. The optimum pH varies from system to system and depends on many factors, including the alloy used
To elevate pH, neutralizing amines should be used instead of ammonia, which (especially in the presence of oxygen) accelerates copper alloy corrosion rates. Also, amines form protective films on copper oxide surfaces that inhibit corrosion.

LIME Marine does not corrode, erode, attack, oxidize or have other deleterious affects on virtually any metal or materials found in marine water systems such as: BRASS, IRON, LEATHER, CERAMIC ,WOOD, FIBER, PLASTICS FIBERGLASS, COPPER, STEEL, TITANIUM ,COPPER NICKEL ,RUBBER, GLASS, GELCOATS PAINTED SURFACES.
LIME Marine is an electrolyte, as are most cleaning agents. An electrolyte is any liquid that will transfer small electrical currents. Examples: salt water, vinegar, Coca-Cola. An electrolyte may cause plating in some types of equipment. This means a transfer of small amounts of one metal onto another metal according to the galvanic corrosion chart. In some instances, a thin coating of copper may be plated onto a steel drum while circulating an electrolyte such as RXLYME Marine. The only time plating occurs is when two dissimilar metals are in an electrolyte solution.
It is recommended, but not mandatory, that the LIME Marine solution be thoroughly mixed before using. Some settling of a dark precipitate may occur, resulting in an amber colored liquid, but has no negative affects upon the performance of the solution.

Pet Coke STAIN removal concept -
Coal and petcoke leaves stain, its removal is important task during hold cleaning operation. Our expert has 2 suggestion for removal of such stain from the surface.
1st one to use RX Tuff heavy-duty alkaline cleaner, which can apply as an emulsion, need time to take effect and are rinsed away with seawater. More than one application will be needed to remove stubborn stains.
2nd one solution is much more effective than 1st one step. Here our expert suggests using New ORG on the spotted area where the residue is tightly deposited on the surface. " New ORG -RXSOL-20-2020-025 " this product is specialized to react with oily residue where any alkaline cleaner fails to emulsify. Uses of New ORG chemicals for stain removal/cleaning principally dissolve and emulsify OIL RESIDUE stain completely which is resulting stain-free surface, Then without flushing with water follow 1st step.
