Formation of Calcium Sulfate is main cause for SCALE formation :::

The principal problem potential posed by sulfate ions in water is the possibility of calcium sulfate scale formation.  Precipitation of calcium sulfate can occur when high concentrations of both calcium and sulfate exist simultaneously.  There are three primary areas of water treatment in which calcium sulfate precipitation may occur boilers, cooling systems, and ion exchangers operating in the hydrogen or acid mode.

In boilers, calcium sulfate scale formation has been reduced to a minimum by modern treatment practices.  The low hardness levels largely preclude calcium sulfate boiler scale.    By contrast, cooling systems are subject to calcium sulfate scale deposition because the makeup is usually not treated for hardness removal.  Cooling water is usually treated with sulfuric acid for pH control, and the makeup is cycled, i.e. concentrated.  Calcium sulfate scale deposition can  result unless the cycles of concentration are properly controlled in conjunction with the proper use of scale control chemicals.  Cation ion exchangers regenerated with sulfuric acid also can pose a major calcium sulfate problem. Calcium sulfate precipitation can be avoided by controlling the acid concentration and the flow rate through the exchanger.

RXSOL-51-6001-025 is a concentrated  solution of a POLYELECTROLYTE  polymer and Antifoaming Agents for  use in SEA WATER evaporator  as a controller of scale and foam in side the  evaporators.  It can be used as a scale inhibitor  in the  feed water  to EVAPORATORS producing fresh water .

A liquid polymer-based evaporator treatment specially designed to control and prevent scale formation in evaporators

Carbohydrazide is used as an oxygen scavenger for high pressure boilers in power plants and other industries to reduce corrosion of metal pipes and fittings.

What is CarboHydrazide ?
Carbohydrazide the hydrazide of carbonic acid.

Why Hydrazine is replace by Carbohydrazide ?
Carbohydrazide (CH6N4O) - RXSOL-42-2541-025 is an oxygen scavenger often added to boiler systems to control corrosion. It reacts with oxygen at low temperatures and pressures. It also passivates metal surfaces preventing further corrosion. The reaction products are volatile, so they do not contribute to dissolved solids in the system. Carbohydrazide is widely used to replace hydrazine as an oxygen scavenger because it is less toxic.

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.

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.

The most common applications of oxygen scavenger in oil and gas production are for seawater injection facilities, hydro-testing, and acid stimulation
