Frequently Asked Questions about Boiler treatment
Answer:
A corrosion scale inhibitor is a chemical solution designed to prevent rust, corrosion, and scale formation inside boiler systems. It protects metal surfaces from degradation and ensures smooth heat transfer, ultimately extending the lifespan of the boiler and reducing energy costs and maintenance downtime.
Answer:
Choosing the right inhibitor depends on:
Boiler pressure and temperature
Feedwater quality (e.g., hardness, pH, oxygen content)
Type of scaling or corrosion (e.g., calcium carbonate vs. oxygen pitting)
Look for inhibitors that are multi-functional, offering both scale and corrosion protection, and ensure they’re compatible with your boiler material (carbon steel, copper alloys, etc.).
Answer:
The frequency of dosing depends on your boiler’s operating conditions, feedwater quality, and the type of inhibitor used. Typically, dosing is done continuously through a dosing pump or daily during boiler operation. Regular water testing and monitoring (pH, conductivity, hardness) is essential to maintain the correct inhibitor levels and ensure optimal protection against corrosion and scale.

The most common oxygen scavengers in oilfield production are sodium bisulfite (SBS) and ammonium bisulfite (ABS). Ammonium bisulfite is more water soluble than sodium bisulfite and typically react with oxygen faster. However, ammonium in the ammonium bisulfite can promote bacteria growth.
Being a salt of a weak acid and a strong base, sodium bisulfite forms a significantly basic aqueous solution whereas ammonium bisulfite is only slightly basic at around pH 8. As a rule of thumb, 60ppm of 65wt% ammonium bisulfite is required to reduce the oxygen concentration in water from 9ppm to 50ppb.
The reaction of bisulfite with oxygen is typically faster at higher temperatures and can be facilitated by transition metal ion catalysts, e.g. Cobalt.

CorroSOL 50 Molybdate Corrosion Inhibitor closed cooling systems Molybdate Phosphonate is very effective in high hardness, highly alkaline scaling waters. It contains a proprietary blend of organic and polymeric sequestrants, penetrants and dispersants to minimize system fouling from contaminants such as calcium, silica, iron, sludge and organics. It also contains a unique blend of organic and actives to corrosion sites. Corrosion inhibitor closed cooling systems Molybdate Phosphonate is very effective also in low hardness, low alkalinity corrosive waters. It contains special filming ingredients to establish protective barriers against corrosion on ferrous metal surfaces. It also contains special filming ingredients to establish a protective barrier against corrosion and pitting on both yellow metal and ferrous metal surfaces.
Corrosion inhibitor closed cooling systems Molybdate Phosphonate is environmentally safe for discharge with the cooling system bleedoff. The formulation contains no heavy metals, chromates, or other pollutants requiring removal or treatment prior to discharge at normal usage rates.
Molybdate does not provide a nutrient source as do many other corrosion inhibitors. This eliminates a food source for algae and bacteria in the water system and makes control of microorganisms easier at lower microbiocide dosage rates. Corrosion inhibitor closed cooling systems Molybdate Phosphonate may be used alone as a single product for control of corrosion in systems where hardness and alkalinity does not pose a scaling problem, or in high hardness and/or high alkalinity waters where higher cycles of concentration and lower bleed rates are desired. Corrosion inhibitor closed cooling systems Molybdate Phosphonate offers superior corrosion protection for all metals typically found in cooling water systems. The blend of cathodic and anodic inhibitors provides a durable corrosion inhibitive film for maximum system protection and minimal corrosion rates.

CorroSOL 50 Molybdate Corrosion Inhibitor is low hazard, non-toxic and easy to use making it the ideal treatment for closed chilled water and LTHW and MTHW heating systems.
*Note: Whilst CorroSOL 50 Molybdate Corrosion Inhibitor is designed to protect systems which incorporate aluminium it should NOT be used in systems with Ideal Super Plus modular boilers where an alternative product F1-HVAC should be used, and in all applications where aluminium is present it is important to control the pH in the range of 7-8.
5 – 10 litres / 1000 litres of system water and make-up (in systems not containing Aluminium)
10 – 15 litres / 1000 litres of system water and make-up (in systems containing Aluminium)
Normal treated water control limits
pH 7.0 – 9.0 (Without Aluminium)
pH 7.0 – 8.0 (With Aluminium)
Molybdate: >33mg/l min. (Without Aluminium)
Molybdate: >66mg/l min. (With Aluminium)
TDS: 2000mg/l max.
TVC: 103 cfu/ml max.
For systems which don’t contain aluminium CorroSOL 50 Molybdate Corrosion Inhibitor should be added to the system at an initial dosage rate of 5 – 10 litres / 1000 litres of system water content (increase to 10 – 15 litres / 1000 litres for systems containing aluminium). This will passivate metal and should establish the required minimum Molybdate reserve of >33mg/l. Whenever the system is drained or loses a significant quantity of water then the additional CorroSOL 50 Molybdate Corrosion Inhibitor should be added at the rate of 5 – 10 litres / 1000 litres of water added (increase to 10 – 15 litres / 1000 litres for systems containing aluminium).
NB For systems containing aluminium it is important to maintain the system water pH in the range 7.0 – 8.0. Occasionally depending on the water characteristics and system treatment history the pH may rise above pH 8.0 which means that the risk of aluminium corrosion is increased – if this happens then high pH can be reduced by adding an appropriate quantity of pH Conditioner.

Why Condesate control ( Condensnol Amine ) required as BOILER Water Treatment chemicals?
Condensate control plays very important role to neutralize Acidic nature of boiler water steam during condensation process. As acidic nature rapidly corroding metal body of BOILER and surrounding system.
What is the main base and chemical principle of Condensate Control (Condensnol Amine )?
Condensate control contain mixture of condensnol amine which helps to neutralize acidic media which causes corrosion in boiler system. On the other hand we can say that condensate control works as a corrosion controler in steam and condensate systems.
Is Condensate System can be kept safe by using Condensnol amine - condensate Control?
Condesnol Amine ihighly effective product to CONTROL acidic strength of CONDENSATE SYSTEM. During liquid treatment Condensnol amine neutralises the acids in the condensate system.
Is Condensate control is easy to use?
Corrosion Inhibitor for Boiler Neutralizer condensate is tested for PH to determine the dosage level. The PH limits are 8.3 - 9.0 . For an average system e. g. 10-M3, the dosage is approximately 0.65 ltr / day .
The necessary amount of Corrosion Inhibitor for Boiler Neutralizer is required or injected as frequently as to maintain the pH of the condensate at the main condensate pump outlet between 8.6-9.5 . The amines pass over with the steam and have the dual function of elevating the pH of the steam/condensate and putting a protective micro film on the system pipe work. Acidic condensate is the result of carbonic acid (H2CO3) being formed as CO2 is released in the steam.Condensate prevents corrosion by carbonic acid on live systems. Its filming properties also reduce corrosion on shut down lines, when moisture and oxygen are present.

Chemical feed should be continuous. Chemical pumping rates can create problems especially for neat feed set ups. Using on/off feed systems such as a recycle timer can create problems. Chemical feed pumps should be sized or product strengths should be adjusted to allow continuous feed.
Steam and carbon dioxide leave continuously, so setting up a neutralizing amine pump to feed intermittently can lead to wide variations in condensate pH control. If sampling is done from a condensate receiver, the tank volume may buffer the variations and the changes may not be noticed, but corrosion could be occurring to areas of the piping that see the rapidly changing pH.
If polymeric dispersants, phosphonates, phosphate, or chelants are fed intermittently into the feedwater using a recycle timer, and the amines are not fed continuously, a cycle of iron slugs returning in the condensate can be followed by slugs of high dispersancy cleaning of the iron from the deaerator and dragging it into the boiler.
Load changes can affect chemical concentrations when the chemical feed is base fed. Example: Steam production of one million lbs./day; 4% blowdown; 20% active boiler polymer product fed at 5 pounds per day. The calculated daily average polymer concentration would be 24 ppm. Assume peak plant production load is 60,000 lbs./hr., but during the overnight hours the load is only 5,000 lbs./hr. If the dispersant is being fed continuously over the 24 hours, during the 8- hour low load period, the boiler polymer concentration would have increased to over 200 ppm. Upon high fire when production resumes, carryover is very possible because of over concentrating the polymeric dispersant.
Chemical feed needs to be paced to steam production, especially where significant load changes occur.
Carbon dioxide can concentrate in steam and condensate making neutralizing amine treatment impractical. Carbon dioxide levels can be relatively low in steam exiting a boiler at only a few ppm, but if there are areas where it becomes “trapped” and can accumulate, concentrations can reach extremely high levels into the hundreds or even thousands of ppm.
CO2 is a non-condensable gas. It has a distribution ratio in the steam piping and condenses at points throughout the system. At the boiling point, the solubility of the gas in water is extremely low. The solubility of the CO2 is actually lower in the condensate than it is in the steam. For the CO2 to escape from the steam into the water it will accumulate in the steam space just above the water level until the partial pressure becomes high enough for the CO2 in the incoming steam to be able to exit into the condensate. This creates a steady state condition of CO2 coming in and exiting, but an area of severe localized corrosion occurs where the carbon dioxide concentration is high.
The highest CO2 concentration normally occurs just above the condensate water level. If there is an area where condensation is occurring and running down pipes or the sides of vessels, the CO2 concentration will be very high and the pH will be about 5.3 – 5.5 in that location creating high corrosion rates.
The solubility of CO2 increases dramatically as the condensate temperature falls below 212 °F. When there is an accumulation of CO2 in an area and the condensate temperature is relatively low, the amount of carbon dioxide going into solution will be extremely high. Where low-pressure steam is used that contains CO2 and the heat exchange process has relatively close temperature differentials between the steam and the condensate, there is potential for high uptake of the CO2 into the condensate and localized low pH.
Neutralizing amines are selected in an effort to condense in the right concentrations to carbon dioxide condensation levels throughout the steam system. Neutralizing amines cannot control corrosion where this localized accumulation of carbon dioxide occurs since the high CO2 overwhelms the demand for the amine. Even point source addition of amine may not be able to satisfy the demand.
Where the concentrating effect of CO2 occurs, methods of reducing the problem include eliminating or minimizing CO2 in the steam, venting off the CO2 in the localized area, eliminating condensate in the area, applying a filming amine or metal passivator, or using higher temperature steam and increasing condensate temperature to reduce the CO2 content in the condensate.
