In today's industrial production, water treatment technology is an important link to ensure the stable operation of equipment and extend the life of equipment. Faced with the common problems of oxidative corrosion and scale deposition in boilers, pipelines, heat exchange equipment, and other systems, it is crucial to choose an efficient, environmentally friendly, and economical water treatment agent. Our hydrazine carbonate water treatment agent came into being in this context.
Carbohydrazide is also known as carbohydrazide, 1,3-diaminourea, and carbohydrazide. It is a white, short, columnar crystal or white crystalline powder at room temperature. It is difficult to dissolve in ethanol, very soluble in water, and absorbs heat when dissolved. It is insoluble in alcohol, ether, and benzene. Because it is a derivative of hydrazine, it has strong reducibility and is non-toxic. It can replace hydrazine hydrate and oximes. It has a wide range of uses in industry. In the field of water treatment, it can be used as a deoxidizer for boiler water. It is the most advanced material used for boiler water deoxidation in the world today. It has low toxicity, a high melting point, and deoxidation efficiency far greater than the currently used materials. It is an ideal, safe, and environmentally friendly product; it can also be used as a component of rocket propellant; and because the hydrogen atoms connected to nitrogen atoms are easily replaced by other groups, it can also be used as a crosslinker for elastic fibers, a formaldehyde scavenger, and an antioxidant for pigments such as carotene in the textile industry. In addition, adding an appropriate amount of carbohydrazide to soap containing phenolic fungicides can prevent discoloration and rancidity. As a chemical raw material and chemical intermediate, it is widely used in medicine, herbicides, plant growth regulators, dyes, and other industries.
Carbohydrazide (propionamide) is a new type of organic synthesis intermediate. It is an organic compound produced by the alkalization reaction of urea and carbamate. It can be used to produce methoxybenzoic anhydride (PA), melamine, and amino acids.
1. Raw materials: The main raw materials of carbohydrazide are urea, carbamate, ethanol, sodium hydroxide, etc.
2. Carbohydrazide synthesis process: First, add urea to a container, add ethanol, and stir to dissolve; then add carbamate, add a certain amount of sodium chloride, adjust the pH value, and heat and stir at 50 to 60°C; after stirring for 10 hours, change the pH value to obtain carbohydrazide.
3. Dehydration: Dehydrate the carbohydrazide and ethanol mixture in the reaction solution. At this time, the concentration of carbohydrazide solution can reach 20%. Then use a dehydrator to dehydrate the carbohydrazide again. The concentration of the dehydrated carbohydrazide solution can reach 95%-98%.
4. Crystallization: Cool the carbohydrazide solution to 0°C and start crystallization, or use suction filtration to separate the carbohydrazide, and the carbohydrazide suspension can be further purified by a centrifuge and then precipitated. Under appropriate temperature and H conditions, carbohydrazide can quickly precipitate crystals, and the crude carbohydrazide can be obtained by screening.
5. Refining: The crude carbohydrazide is refined with a solvent to obtain the final product.
Carbohydrazide can be added to water during boiler deoxygenation, or a carbohydrazide aqueous solution can be used. 0.5 moles of carbohydrazide are required for each mole of O₂, and an appropriate excess. The applicable temperature range is 87.8 to 176.7 degrees Celsius. Carbohydrazide should be used after thermal deoxygenation. The reaction formula of carbohydrazide and oxygen is as follows: CON₄H₆ + 2O₂ = 2N₂ + 3H₂O + CO₂.
1. Carbohydrazide can be added directly to water or through water treatment equipment.
2. The amount used should be adjusted according to the hardness of the water, the water quality, and the concentration of the treatment agent.
3. Impurities and sediment in the water tank or water pipe should be removed before adding.
4. Stir well after adding to ensure that the treatment agent is evenly distributed.
After adding, the treatment agent should be allowed to fully act for a period of time before use.
Using an advanced chemical formula, this product can quickly remove dissolved oxygen in water, significantly reduce the risk of corrosion caused by oxidation of metal equipment, and thus ensure the long-term stable operation of the equipment.
The carefully designed formula effectively inhibits scale formation and, at the same time, has a good dispersion effect on impurities and organic matter in water, keeps the inner wall of the pipeline and equipment clean, and further improves the heat transfer efficiency and overall system efficiency.
The application characteristics of low dosage and high efficiency not only reduce the consumption of reagents but also meet strict environmental protection standards, avoid secondary pollution, and provide strong support for enterprises to achieve green production.
Whether it is a large thermal power plant, industrial boiler, chemical production line, or cooling system of papermaking and food industry, you can flexibly formulate the addition plan according to the specific water quality and working conditions to ensure the best water treatment effect.
1.Sterilization and odor removal: Carbohydrazide has a bactericidal effect, which can kill bacteria and viruses in water and effectively control water quality. In addition, it can remove odors such as odor and odor in water, making the water quality fresher.
2. Removal of heavy metal ions: Carbohydrazide can remove heavy metal ions such as lead and mercury in water, thereby improving the purity and cleanliness of water quality.
3. Anti-corrosion effect: Carbohydrazide can prevent water pipes and water tanks from rusting and extend their service life. By preventing the metal surface from contacting oxygen and corrosive substances in the water, the occurrence of corrosion and rust is reduced.
4. Deoxygenation effect: In boiler water treatment, carbohydrazide is used as a deoxidizer. Oxygen in boiler water can cause corrosive substances to enter the boiler, form iron scale, and increase pipeline resistance. Carbohydrazide can react chemically with oxygen in water, effectively remove oxygen, and prevent boiler corrosion and pipeline blockage.
A large thermal power plant located in North China faces problems of oxidative corrosion and scale deposition during boiler operation. After using our company's hydrazine carbonate water treatment agent, the dissolved oxygen in the boiler water was significantly reduced, and the risk of internal corrosion of the equipment was greatly reduced. Practical application shows that the thermal efficiency of the boiler has increased by about 2%, the maintenance cost has been reduced by 15%, and the service life of the boiler equipment has been extended.
A chemical plant has extremely high requirements for process water quality, and traditional water treatment methods are difficult to balance with corrosion and scale prevention. After the introduction of hydrazine carbonate water treatment agents, the equipment operation of the entire production line has become more stable, and the scale deposition problem has been effectively improved. After six months of continuous operation, the equipment failure rate has dropped by 30%, and production efficiency and product quality have been significantly improved.
In papermaking production, the cooling water system often reduces efficiency due to microbial growth and mineral deposition. After a papermaking enterprise added hydrazine carbonate water treatment agents to the cooling cycle, the water quality was significantly improved, the equipment cleaning cycle was extended from the original 90 days to more than 120 days, the system's energy consumption was also reduced, and the overall operation was more stable.
In the field of industrial water treatment, choosing efficient, environmentally friendly, and economical treatment agents is not only a protection for equipment but also a key guarantee for the sustainable development of enterprises. With its unique formula and advanced technology, hydrazine carbonate water treatment agents have become the preferred solution for many industry customers to optimize water treatment processes, reduce maintenance costs, and increase equipment life.
