Sulfamic Acid Inhibited - Sulfamic Descalant

Sulphamic acid is very useful products for removing scales obtained from water in heating and cooling systems e.g. boilers, condensers, heat exchangers, jackets and coils

Sulfamic Acid is a Zwitterion, a molecule with two charges that counteract each other, the Nitrogen and Oxygen have a greater pull on the bond pair of electrons due to the high electro-negativity, this causes the bond to be polar, the Nitrogen and Oxygen draw the electrons closer and become slightly negative, the Hydrogens become positive because the negative electrons are further away.

Grades of Sulphamic acid as a descalant:

The GP grade of Sulphamic acid:

The GP grade may be used for removing scales obtained from water in heating and cooling systems e.g. boilers, heat exchangers, condensers, jackets and coils.

The SR grade of Sulphamic acid:

This formulation is recommended for scales containing high silica. Typical examples are scales found in caustic evaporators in the Aluminum industry and black liquor evaporator in the pulp industry.
 

The  RXSOL TM grade of Sulphamic acid:  SUPERIOR BLEND of Corrosion inhibitor

This formulation is recommended for removal of scales from heat exchangers made of Titanium metal.  We provide Sulfamic Acid descalant that has scale solubilizing capacity and added corrosion resistance blends which offer maximum protection to metal of equipment being cleaned. Our range of Sulfamic Acid descalant is ideal for removing scales from cooling towers, boilers, heat exchangers, coilers, condensers, and various other heating and cooling systems. We also provide Sulfamic Acid descalant in self-indicating grade that changes colors to indicate that the efficiency of material has been finished.

CHEMICAL STAGE :

A strong crystalline acid, Sulfamic Acid is also known as an intermediate compound between Sulfuric Acid (H2SO4), and Sulfamide (H4N2SO2) and a dry, non-volatile, non-hygroscopic, odorless, white crystalline, stable acid, moderately soluble in water that forms strongly acidic aqueous solution, comparable in acidity to the common strong mineral acids.

In industrial water systems, scale accumulation is a persistent problem that can reduce heat-transfer efficiency, restrict water flow, increase energy consumption and accelerate equipment deterioration. RXSOL Sulfamic Acid Inhibited is an inhibited acid descaler formulated for the controlled removal of mineral scale and deposits from industrial equipment.

Sulfamic acid is widely used as an acidic cleaning and descaling agent for metals and ceramics. Its aqueous solutions can dissolve carbonate and other mineral deposits while generally offering lower metal attack than some stronger mineral acids.

What Is RXSOL Sulfamic Acid Inhibited?

RXSOL Sulfamic Acid Inhibited is a sulfamic-acid-based descaling chemical containing corrosion-inhibiting chemistry. The inhibitor is important because acid cleaning must remove mineral deposits while minimizing unnecessary attack on the underlying metal.

RXSOL identifies the product as RXSOL-43-1304-125, with an active-matter specification of approximately 95-96% for the inhibited sulfamic-acid product.

The product is supplied as a dry crystalline material that dissolves in water to produce an acidic cleaning solution.

How Does Sulfamic Acid Remove Scale?

Many industrial deposits contain calcium carbonate and other mineral salts. When sulfamic acid contacts acid-soluble scale, the deposits react with the acid and are converted into soluble sulfamate salts and other soluble products.

This allows the hard mineral layer to progressively dissolve and detach from the equipment surface.

Sulfamic acid is particularly useful for carbonate and certain sulfate-containing deposits, and technical references note that it can be more effective than hydrochloric acid for some sulfate scales.

Why Use an Inhibited Form of Sulfamic Acid?

Using an acid without corrosion protection can result in unnecessary metal loss during descaling.

Research into sulfamic-acid cleaning has demonstrated that metals such as mild steel, aluminum, copper and brass can undergo corrosion in sulfamic-acid solutions, while suitable inhibitor systems can substantially reduce this attack.

The corrosion inhibitor in an inhibited formulation is therefore intended to provide an additional layer of protection while the acid performs the descaling process.

This makes inhibited sulfamic acid particularly useful for circulation cleaning and immersion cleaning of industrial equipment, provided that the metallurgy, temperature and concentration are appropriate.

Application

White crystalline soild, non volatile, non volatile, non hydroscopic. Soluble in water and odorless. Toxic by ingestion.

Uses: Metal and ceramic cleaning, amine sulfamates, ph control, hard water scale removal, electroplating.

At room temperatures, dilute aqueous Sulfamic Acid solution is stable for a long time but rapid hydrolysis occurs at elevated temperatures. Its solution is less corrosive toward metals than other mineral acid. When compared to most of the common strong mineral acids, Sulfamic Acid has desirable water descaling properties, low volatility, low toxicity and is a water soluble solid forming soluble calcium and iron-III salts. Because of its many positive attributes like handling ease, solubility and low corrosiveness, Sulfamic Acid is used for many diversified applications.

•    Used in cold as well as with temperature ranging from 40º to 60ºC
•    Sulfamic Acid is a very safe and highly effective descalant
•    Sulfamic Acid provides good cleaning and reduces manual cleaning.
•    Sulfamic acid is recommended for the cooling water for descaling the condenser on running plant basis.

Applications Of Sulphamic Acid:

Sulphamic acid in descaling

Sulphamic Acid is super efficient descaling agent and is used for cleaning a variety of industrial equipment and domestic appliances.

Sulphamic acid in paper & pulp Industry

Sulphamic Acid prevents pulp degradation due to temperature at the chlorination and hydrochloride stage. It permits bleaching at higher temperature and lower PH without loss of strength.

Sulphamic acid is used in manufacturing of Dyes, Pigments and in the dyeing of leather

Sulphamic Acid removes excess of nitrides used in the diazotization reactions in the manufacturing of dye stuffs and pigments. Nitrides if present in process water of effluents can also be removed by using Sulphamic Acid

Sulphamic acid in Chlorine Stabilization

Chlorine gas in water form HOCL which reacts with Sulphamic Acid form N-Chloro-Sulphamic Acid to N-ChloroSufamic Acid more stable and yet has active chlorine, Because of this, Sulphamic Acid is used for stabilizing chlorine in swimming pools and cooling towers.

Sulphamic acid in Electroplating and Electro-refining

Metal sulphamate electrolytes values for their high solubility cadmium, cobalt nickle, lead silver and radium sulphamte deposits are bright and dense. Lead sulphamate is used in refining lead when a high quality is desired.

Sulphamic acid in Sulphation and Sulphamation

Sulphamic acid is used for sulphation and sulphamation of many organic compounds. Sulphation of aklyl pheno-ethylen oxide condensation products 9for detergents and sulphation of ethoxylated phenol-formaldehyde resins is preferable with Sulphamic Acid. Stronger agents cause unwanted ring sulphomation.

Sulphamic acid in the Plastic industry

Sulphamic acid finds application in the plastic wherever a curing agents is required which does not have the disadvantage of inorganic acids and which acts faster than organic acids.

To summarise point wise, RXSOL Sulfamic Acid Inhibited finds application in following areas for scale cleaning/removing:
