Boiler Chemicals-42

The correct dosage rate is dependant upon several parameters, including feed temperature, pH, and chemical analysis and will be specified by your consultant after a detailed survey of your plant. To obtain the best results, Antiscalant 9209 RX should be added continuously using a suitable metering pump.

In general PRACTICE :
Antiscalant 9209 RX should be dosed continuously to the feed water upstream of the cartridge filters. Typical dosage rates are 2 – 4 mg/L.
Antiscalant 9209 RX may also be used in sea water applications where iron is present, recycle of brine is in use or there is no feed water pH reduction by acid dosing.

Typical dose rates are 0.5 – 1.0 mg/L
Antiscalant 9209 RX dose rate in the feed water should be less than 5 mg/L in potable water systems. 
Antiscalant 9209 RX can be diluted and is fully miscible with water in all proportions.
 

Cool Water Treat should be dosed to a suitable point in the system. If the expansion tank is used, adequate circulation must be assured.

Dosing and Control

Initial dosage for an untreated system is 60 litres of Cool Water Treat Cool water Treat Corrosion Inhibitor / ton of untreated distilled water (6%). This will provide sufficient protection of the system for a period of two to five years under normal conditions. 6% Cool water Treat Corrosion Inhibitor should also be dosed in all make up water added to the system to compensate for lost coolant. The engine manufacturer's recommendations for water quality should always be complied with. Chloride levels should always be as low as possible. Most engine manufacturers recommend a maximum of 50 ppm chlorides. For this reason, RXSOL Service recommends the use of distilled water as make-up.

Suitable and very popular product for DESCALING of high and low pressure boilers, Heat EXCHANGERS etc. Its corrosion inhibitor blend PROVIDE metal protection

This is mixed with fresh water 3 to 20 percent depending on deposition of scaling. After using SA-1008, sense all metal surfaces with 0.5 percent of RXSOL-54-1008-025 at least 2-4 house , up to neutrial of PH valve.
 

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. This should not be done more than twice. RXSOL-54-1008-025  should not be used on Aluminium , Zinc, Tin or Galvanized surfaces.

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.

Evaporators, Calorifiers, Heat Exchangers:
The strength of the acid can be enhanced by adding 1 part sodium chloride (common salt) to 20 parts of Descalex. This enhancement of the cleaning solution, however, should not be used when descaling diesel engine cooling water systems. After use of Descalex a 0.5% solution of Alkalinity Control in fresh water should be used for neutralisation.

House Hold : One of the most common uses of hydrogen peroxide is as a disinfectant. Spray it on surfaces like kitchen counter top and wipe with a clean rag. It can be used as a mouthwash too. You have to dilute the chemical with water and use it for rinsing the mouth. This mouthwash is also said to whiten teeth. Ensure that you do not swallow the liquid, while rinsing.
It can also be used to wash vegetables and fruits, in order to get rid of germs and pesticides. Add some hydrogen peroxide to a bowl full of water (you may also add a few pinches of salt). Soak the veggies and fruits for some time. Remove them and rinse with cold water, before use.This chemical is also used to purify water in swimming pools.
 

Agriculture : Farmers use it as an insecticide. They spray diluted form of this chemical, on plants, so that the pests and weeds get killed, without causing harm to the plants. Its also used for watering plants. Mix an ounce of this chemical with a quart of water and use it on plants. Apart from boosting the level of oxygen in the soil, this mixture is also said to prevent root rot. Some people soak seeds in it, after diluting it with water. It is said that this will fasten the process of germination. For this purpose have to mix 1.5 teaspoons of hydrogen peroxide in a cup of water.

Textile: It acts as a stain remover. Put 1 spoon tea in 1 bucket water  and let it sit for a while. After that, rinse the stains with water and soap.
As it has bleaching property, it is used as a bleach too.

Reduced Sulfur Compound Treatment for Refinery Wastewater

Sulfur compounds, such as hydrogen sulfide, thiosulfates and mercaptans, can present serious refinery wastewater problems. Hydrogen peroxide treatment is a cost effective way to treat these reduced sulfur species.

Supplemental Dissolved Oxygen to Reduce BOD and COD

Hydrogen peroxide has been used to reduce BOD and COD in refinery wastewater Supply of Supplemental Dissolved Oxygen (DO) when biological treatment systems experience temporary overloads or equipment failure.Predigestion of wastewater which contains moderate to high levels of compounds that are toxic, inhibitory or recalcitrant to biological treatment.As indicated by these examples, hydrogen peroxide can be used as a stand-alone treatment or as an enhancement to existing physical or biological treatment processes, depending on the situation.

Wastewater Pretreatment
Hydrogen peroxide is one of the most versatile, dependable and environmentally compatible oxidizing agents. The relative safety and simplicity of its use as an oxidizing agent has led to the development of a number of applications in refinery wastewater systems.
