Urine-based properties, uses, upstream and downstream raw materials and storage methods analysis

1. urinary base properties

1. Chemical composition

Urea, chemical name for urea, molecular formula CO(NH2)2, is a nitrogen content of up to 46% of organic compounds. The urine base is a white crystal at room temperature, which has the characteristics of odorless and tasteless. Its molecular structure contains two amino (-NH2) groups and a carbonyl group (C = O), which makes the urea group have high solubility.

2. Physical and chemical properties

Urethane has a melting point of 132.7°C, at which temperature it decomposes into ammonia and isocyanic acid. It has a high solubility in water and releases a small amount of heat when dissolved, showing a weak endothermic reaction. Uroyl also has some solubility in ethanol and ether, but is insoluble in benzene, chloroform and other non-polar organic solvents.

2. urine base use

1. Fertilizer application

The most widespread use of urine base is as nitrogen fertilizer, used in agricultural production. Due to its high nitrogen content and good water solubility, the urine base can be quickly absorbed by the soil to provide nitrogen for crop growth, thereby promoting crop growth and increasing yield. It is often made into granular fertilizer, applied directly to the field or mixed with other fertilizers.

2. Industrial application

In the industrial field, urea-based is used in the production of resins, plastics, adhesives, coatings and other products. For example, urea-formaldehyde resin is an important industrial material generated by the reaction of urine-based and formaldehyde, which is widely used in the manufacture of plywood and other composite wood products. Urogen is also used in the production of certain pharmaceuticals, cosmetics and animal feed additives.

3. Environmental protection application

Urethane also has important applications in the field of environmental protection. For example, it can be used in selective catalytic reduction (SCR) technology to reduce nitrogen oxide emissions in diesel engine exhaust. Urethane reacts with nitrogen oxides at high temperatures to produce harmless nitrogen and water, thereby effectively reducing pollutant emissions.

3. urine-based upstream and downstream raw materials

1. Upstream raw materials

The primary upstream feedstocks for urea include ammonia and carbon dioxide. These two kinds of raw materials under high temperature and high pressure conditions through chemical reaction to generate urine base. Ammonia is usually derived from natural gas or coal chemical processes, while carbon dioxide is collected from various combustion processes or industrial by-products. The production process of urea-based is mainly synthetic ammonia process and urea synthesis process.

2. Downstream products

There are a wide range of urea-based downstream products, including various forms of nitrogen fertilizers, urea-formaldehyde resins, and urea derivatives (e. g., urea nitrate, ethyl carbamate). As the main downstream product of urine base, nitrogen fertilizer is widely used in agriculture, which can effectively improve the yield and quality of crops. Urea-formaldehyde resin is an important industrial raw material, widely used in the manufacture of plywood, furniture, coatings and so on.

4. urine-based storage method

1. Storage environment

The urine base needs to be kept dry and ventilated during storage. Because the urine base has strong hygroscopicity, it is easy to absorb moisture in the air and agglomerate, so it must be stored in a dry environment to avoid contact with moisture in the air. The storage warehouse should be kept well ventilated to prevent the urine base from being damp or decomposed due to temperature changes.

2. Packaging requirements

Urine bases are typically stored and transported in bagged or bulk form. Bagged urine base should use moisture-proof and leak-proof packaging materials, such as plastic woven bags or composite bags, to ensure that it is not affected with moisture during storage and transportation. Bulk urine bases shall be stored in specially designed tanks or silos with good sealing and moisture resistance.

3. Safety precautions

The urine base should also pay attention to fire prevention and explosion prevention during storage and transportation. Although urine does not belong to the basic body of flammable and explosive materials, but its decomposition products-ammonia has a certain degree of risk. Therefore, contact of the urea group with acidic substances or strong oxidants should be avoided to prevent chemical reactions. The storage area should be equipped with necessary fire fighting equipment and ventilation facilities to cope with possible emergencies.

5. urinary-based market prospects

1. Demand outlook

With the growth of the global population and the acceleration of agricultural modernization, the demand for high-efficiency fertilizers will continue to increase. As a kind of high efficient nitrogen fertilizer, urine base has a wide application prospect. Especially in developing countries, agricultural production is highly dependent on urine-based, so the demand for urine-based market is expected to grow steadily.

2. Price trends

The price of urine base is affected by many factors such as raw material price, production cost and market demand. In recent years, with the fluctuation of crude oil price and the influence of environmental protection policy, the production cost of urine base has increased, which has pushed up its market price to a certain extent. Because of its wide application field and importance, the market price of urine base still has a certain stability.

3. Competitive landscape

The global urine-based market is highly competitive, and the main manufacturers include chemical giants in China, India, the United States, Russia and other countries. Through technological innovation and large-scale production, these enterprises continuously improve production efficiency and product quality, so as to occupy a favorable position in market competition. With the improvement of environmental protection requirements, the promotion of low emission and green production technology will also become an important development direction of urine-based production enterprises in the future.

Urogyl as an important chemical product, has broad application prospects and market potential. By optimizing the production process and improving product quality, urinary-based manufacturers can occupy a more favorable position in the fierce market competition.
