Urea, a nitrogen-rich compound with the chemical formula CO(NH), plays a significant role in the oil and gas industry, Urea, also known as carbamide, is a highly soluble organic compound. It is synthesized on a large scale from ammonia and carbon dioxide and is primarily used in fertilizers, which accounts for about 90% of its global production. Chemical Properties Molecular Formula: CO(NH) Molar Mass: 60.06 g/mol Appearance: White, crystalline solid Melting Point: 133C (271F) Solubility: Highly soluble in water, forming a neutral solution Industrial Production The production of urea typically involves the following steps: Ammonia Production: Sourced primarily from natural gas (methane) through the Haber-Bosch process. Reaction with Carbon Dioxide: Ammonia reacts with carbon dioxide to produce ammonium carbamate, which is then dehydrated to form urea and water:2 3 2+ 2NH 3 +CO 2 NH 2 CONH 2 +H 2 O Diesel Exhaust Fluid (DEF): Urea is used to reduce nitrogen oxide (NOx) emissions from diesel engines. DEF, a mixture of 32.5% urea and 67.5% deionized water, is injected into the exhaust stream of diesel engines. Oil Drilling Fluids: Urea can be used in drilling mud formulations to enhance the efficiency of the drilling process. Chemical Manufacturing: Urea serves as a feedstock in the production of various chemicals such as melamine and urea-formaldehyde resins. Desulfurization: It is used in processes to remove sulfur compounds from petroleum products. Market Dynamics Demand: The demand for urea is largely driven by its use in agriculture. However, industrial uses, including those related to the oil and gas sector, contribute significantly to its market. Pricing: Urea prices are influenced by the cost of natural gas, the primary raw material, and global agricultural demand cycles and NEGOTIABLE Environmental Impact: While urea itself is not hazardous, its overuse in agriculture can lead to environmental issues such as eutrophication. Handling and Storage: Urea should be stored in a cool, dry place away from moisture, as it is highly hygroscopic. It is considered non-toxic, but proper safety measures should be followed to avoid dust inhalation or skin contact. Logistics: Efficient transportation and storage solutions are vital to maintain urea quality and manage costs. Regulations: Compliance with international and local regulations regarding chemical handling, safety, and environmental impact is crucial. Market Opportunities: Identifying and targeting markets with growing industrial and agricultural demand for urea can enhance profitability. Origin: Russia/ Kazakhstan. Contact us for more information

Zeolite, the multifaceted mineral catalyst for sustainable innovation is a remarkable group of minerals with astounding versatility Zeolite has increasingly become a cornerstone in sustainable technology and environmental management. These micro porous aluminosilicates - comprised of aluminum, silicon, and oxygen, with their general chemical formula expressed as Mx/n[(AlO2)x(SiO2)y]zH2O, where 'M' represents the exchangeable cations like calcium, sodium, potassium, and magnesium- formed naturally and synthesized for tailored properties, exhibit unique characteristics that make them indispensable across numerous industries, from environmental cleanup to advanced manufacturing. Properties of Zeolite Zeolites are primarily made up of silicon, aluminum, and oxygen in a framework that includes size-selective pores and channels. These structural features are critical because they allow zeolites to act both as molecular sieves, trapping particles based on size exclusion, and as ion exchangers, selectively swapping cations such as calcium, potassium, and sodium. Zeolites are hydrophilic, meaning they can absorb water and other polar molecules. However, modifications during synthesis can adjust this property, allowing for hydrophobic zeolites that are selective for organic compounds, expanding their utility in non-aqueous environments. Versatile Applications: Environmental Remediation: Zeolites are extensively used in water treatment processes to remove pollutants like heavy metals, ammonia, and radioactive isotopes from contaminated waters. Their high ion-exchange capacity makes them excellent for use in both municipal and industrial wastewater treatment plants. Energy Efficiency: In the energy sector, zeolites are pivotal in refining petroleum products through fluid catalytic cracking, significantly enhancing yield and reducing byproducts. Additionally, zeolites are integral to the development of adsorption-based energy storage systems, which are crucial for renewable energy integration. Agricultural Enhancements: Zeolite's role in agriculture extends beyond soil amendment. It is used to stabilize nitrogen in urea-based fertilizers, reducing volatilization and thereby increasing nitrogen use efficiency. This contributes to lower emissions of nitrous oxide, a potent greenhouse gas. Healthcare Innovations: In healthcare, zeolites are being investigated for their potential in drug delivery systems, particularly for targeted cancer therapies. Their porous structure can be engineered to load and release therapeutic agents directly at tumor sites, minimizing systemic side effects.

Ammonia or azane is a compound of nitrogen and hydrogen with the formula nh3. It is a colourless gas with a characteristic pungent smell. Ammonia contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to food and fertilizers. Ammonia, either directly or indirectly, is also a building-block for the synthesis of many pharmaceuticals and is used in many commercial cleaning products. Although in wide use, ammonia is both caustic and hazardous. The global production of ammonia for 2012 is anticipated to be 198 million tonnes, a 35% increase over the estimated 2006 global output of 146.5 million tonnes.Ammonia, as used commercially, is often called anhydrous ammonia. Household ammonia is a solution of nh3 in water (i.E., ammonium hydroxide) used as a general purpose cleaner for many surfaces. Because ammonia results in a relatively streak-free shine, one of its most common uses is to clean glass, porcelain and stainless steel. It is also frequently used for cleaning ovens and soaking items to loosen baked-on grime. Household ammonia ranges in concentration by weight from 5 to 10% ammonia.Because of ammonia's vaporization properties, it is a useful refrigerant. At standard temperature and pressure, ammonia is less dense than atmosphere, and has approximately 60% of the lifting power of hydrogen or helium. Ammonia has sometimes been used to fill weather balloons as a lifting gas. 40l cylinder
