Morpholine Chemical is an organic amine used for boiler water treatment. It increases the pH of boiler water to protect boiler against corrosion.

Morpholine Chemical is an amine-based formulation and does not add salt to the boiler water and thereby does not increase the TDS which results in reduced blow down and fuel savings.

Morpholine can be used in all type, size and pressure of boilers.

Key Features and Benefits

• Prevents stress cracking corrosion
• Does not add TDS
• Reduces blow down requirement
• Saves power
• Compatible with other treatment chemicals
• Returns to the feed line with the condensate return so raises the feed water pH

It is designed for the internal treatment of water used in the boiler. It contains a corrosion inhibitor, an anti-scaling, and a sludge conditioner. It helps to prevent the deposition of calcium, iron, and iron-oxide and also helps in the removal of the existing surface. It also contains a corrosion inhibitor which forms a protective passive film over the boiler heat transfer surface. It keeps heat transfer efficiency and also reduces downtime.

Key Features & Benefits:

• Prevents scale formation • Inhibits sludge formed due to metal ions and metal oxide deposits • Keeps the boiler internals clean and minimizes downtime for maintenance • Prevents corrosion by buffering pH • Compatible with other treatment chemicals • Introduces a passive film on the boiler surface to prevent corrosion • Completely biodegradable and organic chemicals • Enhances heat transfer ability and hence saves energy and increases productivity

Alkali builder or booster chemical is a powerful alkali builder/booster, which is based on a balanced blend of alkali, water hardness sequestering agent and anti-greying agents. The NTA based building system ensures low water hardness ion concentration and consequently prevents precipitation of detergent components. In this way this building system also functions as anti-greying agent by preventing formation and deposition of water hardness salts onto fabric.

It is most commonly applied in conjunction with a surfactant booster. These products combined with bleach offer a powerful system, which may be used for cleaning fabric from hospitals and other healthcare establishments. When combined with a main wash detergent, Speciality alkaline builders enhance the wash performance on heavily soiled goods by increasing the pH of the wash solution.

The control of boiler water pH and alkalinity levels are important issue affecting the operation and maintenance of industrial boiler systems and steam raising plant.

To ensure that such boiler systems are well maintained and operate at optimum efficiency it is essential that the correct water conditions are maintained at all times. This can be achieved using carefully selected alkalinity builders designed specifically to control pH in boiler water systems.

Chemtex’s high quality boiler water alkalinity builders and pH adjusters will help control pH levels in industrial boiler systems, hot water systems, and steam raising plant.

Oxygen scavengers are designed specifically to reduce the amount of dissolved oxygen and oxides in the water. If the amount of dissolved oxygen in boiler water is too high, Oxygen Scavenger helps to reduce the level of oxygen from the feed water, protect the boiler from harmful chemical reactions, and reduce corrosion within the feed tank and return lines. It will passivate various metal surfaces as well, which helps to keep rust and other issues at bay.

Key Features and Benefits:

• Ability to remove dissolved oxygen
• Minimize or eliminates oxidation corrosion
• Works well with water drilling and packing fluids.
• Increase the condensate pH
• Cost-effective
• Thermally stable

Carbohydrazide Chemical in both powder and liquid form finds use oxygen scavenging in boilers to prevent oxidative corrosion. Carbohydrazide is a very effective boiler oxygen scavenger in powdery form, as a formulation. It is used to scavenge even the last traces of DO (Dissolved Oxygen) from the boiler feed water. It prevents corrosion by forming a protective passive film on metal and boosting pH in condensate line. It is highly soluble in water and insoluble in organic solvents.

Carbohydrazide replaces the conventional Hydrazine by overcoming the hazardous carcinogenic effects of hydrazine. Its reducing properties for metal oxides, such as converting ferric oxide to ferrous oxide and cupric oxide to cuprous oxide, finding use in metal passivation.

Key Features and Benefits:

• Long time protection and control against corrosion
• Non carcinogenic nature
• Easy to dose
• Promotes passivation on metal surfaces
• Non residual

Additional Information:

• Packaging Details: 25kgs PP bags

Diethyl Hydroxylamine is an organic compound, mainly used as an oxygen scavenger in water treatments for controlling corrosion in boilers very effectively. It reacts with oxygen to form acetates, nitrogen, and water. It is non-toxic, providing good protection against corrosion at the same time. Due to its capability of inhibiting polymerization in the gas phase, DEHA is finding use as an in-process inhibitor for the production of styrene, divinylbenzene, butadiene, and other monomers. In the boiler, it encapsulates metal surfaces and then passes out of the boiler with steam, passing through a metal passivating agent in the return line system.

Key Features and Benefits:

• Completely organic compound
• Volatile - Does not add TDS to blow down water
• Metal passivator and rust converter
• Effective condensate line treatment and pH booster
• Non-toxic and more safe than hydrazine and carbohydrazide based chemicals
• Compatible with other treatment chemicals
• Returns to the feed line with the condensate return so passivates total system
• High rate of reaction with oxygen compared with other oxygen scavengers
• It offers a vapor-liquid distribution ratio of 1.3 and thus distributes all along the condensate circuit, ensuring a total control of corrosion
• Single treatment for total corrosion control in boiler

Application and Dosage:

Chemtex’s Deha is fed neat (undiluted) continuously to the boiler feed water depending upon the dissolved oxygen content, temperature and pressure of boiler. Theoretically the dosage is 1.3 parts active ingredient for every part of oxygen, but in application, a dosage of 3ppm active for every ppm of O2 is recommended.

Cyclohexylamine is primarily used for low-pressure boilers where the condensate has a long run. It has the ability to stay with condensate steam for longer runs and at various steam pressures which is not a characteristic of other neutralizing amines available. In case the amine requirement is high then there is a possibility of amine carbonate deposit formation. In this case, it is recommended that a blend of other amines be used with Cyclohexylamine for the long run and the low-pressure benefits while preventing carbonate deposition.
