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.

Frequently Asked Questions about Boiler treatment

Q1. What is a corrosion scale inhibitor and why is it important for boilers?

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.

Q2 How do I choose the right scale inhibitor for my boiler?

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.).

Q3 How often should I dose my boiler with a corrosion scale inhibitor?

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.

Our others valauable Products : 
BOILER TREAT ONE SHOT
Combined Boiler Water Conditioner

A one-product treatment for all auxiliary boilers including waste heat, and exhaust gas boilers. it prevents scale formation, inhibits corrosion and conditions sludge.

HARDNESS CONTROL
Boiler Water Conditioner

Added to the boiler water to maintain optimum phosphate level, which prevents calcium and magnesium hardness salts formation. The precipitate can be removed by blow-down.

ALKALINITY CONTROL
Boiler Water Conditioner 

Added to the boiler water to maintain optimum alkalinity level to prevent corrosion. Due to this, Ca and Mg hardness salts cannot form and the precipitate is removed by blow-down.

HYDRAZIDE
Oxygen Scavenger 
Used for rapid removal of oxygen in boiler feed water and condensate systems, which prevents corrosion. It is the alternative for hazardous and potentially carcinogenic products.

BOILER TREAT COMBI
Organic Boiler Water Treatment 
Special blended low molecular weight compounds that elevate boiler water pH to levels, which reduce corrosion. It also prevents under deposit corrosion caused by excess alkalinity.

LIQUID COAGULANT
Oil and Sludge Conditioner 

Used to prevent formation of adherent deposits and sticky sludge in boilers,which are then removed by normal blow-down. It can also be used in the event of an oil contamination.

CONDENSATE CONTROL
Steam and Condensate Conditioner 

Injected into the condensate pump to prevent corrosion in steam and condensate lines.It’s also used to protect idle boilers from corrosion. It neutralizes acidic conditions in condensate systems and volatilizes with steam.

COOL WATER TREAT NCLT
Corrosion and Scale Inhibitor 
Provides an effective anodic inhibitor treatment and protects ferrous and non-ferrous metals. It deposits a microscopic protective film on surfaces and has built-in pH buffering compounds. It controls formation of hard scale deposits.

EVEPORATOR TREAT
Prevention of scale in Evaporators
Used in both high and low pressure evaporators to prevent foaming, carry-over and scale formation. It’s safe to use where distillate is used for drinking purposes. It prevents scale formation and avoids the need for acid descaling.
