Natural Gas Dehydration Unit
The purpose of Dehydration unit is to reduce the water content of the feed gas to avoid corrosion, freezing and hydrate formation in the cryogenic section of the plant by means of desiccants adsorption.
Adsorption gas dehydration is generally used to reach further dehydration levels (water dew point temperatures as low as -40°…-100°С) as a part of cryogenic processing plants.
Naphtha Drying Unit
Naphtha, a volatile liquid hydrocarbon mixture, must undergo thorough drying to eliminate water and other impurities before further processing. To effectively remove water, the naphtha is typically passed through desiccant beds or dehydration units to absorb any moisture present in the stream. The meticulous removal of water is essential to prevent corrosion in refining equipment and safeguard the performance of downstream isomerization catalyst, which are sensitive to moisture contamination.
Air Dehydration/Separation Units
In industrial settings, air dehydration is a crucial process implemented in utility units and air compressors to ensure the efficiency and longevity of equipment. Air, when compressed, can contain moisture that needs to be removed to prevent corrosion, improve the quality of compressed air, and maintain the functionality of downstream components. In utility units, especially in power plants and petrochemical facilities, air dehydration systems such as refrigerated dryers, desiccant dryers, or membrane dryers are employed to extract moisture from the compressed air stream.
Air Separation Unit (ASU) is a vital industrial facility used to separate atmospheric air into its primary components, typically nitrogen, oxygen, as well as other gases in some cases. The ASU operates on the principle of cryogenic distillation, where air is Purified, cooled and compressed before being sent through a series of distillation columns where the components are separated based on their different boiling points. This process involves extremely low temperatures to liquefy and separate the gases effectively.
Separation Iso/Normal Paraffin
Separating iso- and normal paraffins is a critical process in the oil refinery and petrochemical industries to obtain specific products with desired properties. The separation is typically achieved using methods such as distillation, adsorption, and solvent extraction. Distillation is one of the most common methods where the different boiling points of the iso- and normal paraffins are utilized to separate them. Adsorption techniques involve using adsorbents like molecular sieves to selectively capture one type of paraffin while allowing the other to pass through. Solvent extraction relies on the differential solubility of iso- and normal paraffins in various solvents to achieve separation. Each method has its advantages and limitations, and the choice of technique depends on factors like product requirements, efficiency, and cost considerations. Effective separation of iso/normal paraffin is crucial for producing high-quality products.
Air Brake Systems
In the realm of automotive engineering, the air brake system plays a vital role in ensuring the safe operation of heavy vehicles like trucks, buses, and trains. This system relies on compressed air to activate the brake mechanisms, providing a reliable and effective braking solution. One crucial component within the air brake system is the air dehydration filter. This filter is responsible for removing moisture from the compressed air before it enters the braking system. By eliminating moisture, the air dehydration filter helps prevent corrosion, freezing, and malfunctions within the braking system, ensuring its smooth and efficient operation. Furthermore, dry air also helps maintain the overall system’s integrity and longevity, reducing the risk of component damage and enhancing operational safety. The air dehydration filter’s role in maintaining clean, dry air is paramount for the proper functioning and reliability of air brake systems in heavy vehicles.
Double-Paned Windows
Double panel windows are commonly used in modern construction for their energy-efficient properties and insulation benefits. In these windows, desiccants play a crucial role in enhancing their performance and longevity. Desiccants are materials with a high affinity for moisture, often placed between the two glass panels of a double-pane window to adsorb any moisture or condensation that may form inside the unit. By preventing moisture buildup, desiccants help maintain a clear view through the window, reduce the risk of mold growth, and extend the lifespan of the window by preventing damage caused by moisture. Additionally, desiccants aid in improving the overall energy efficiency of double panel windows by preserving the insulating properties of the air or gas trapped between the glass layers. This results in better thermal performance, reduced energy consumption for heating and cooling, and enhanced comfort for building occupants. The inclusion of desiccants in double panel windows is essential for ensuring their effectiveness in maintaining a comfortable indoor environment while prolonging the window’s durability and functionality.
Gold Extraction
The gold extraction process involves several stages beginning with ore crushing and grinding to release the gold particles. Once the gold-bearing ore is finely ground, it undergoes a process called cyanidation, where a cyanide solution is added to the ore slurry. Cyanide forms a complex with gold, dissolving it from the ore. The resulting gold-cyanide solution is then separated from the solid residue. Subsequently, Activated Carbon is used to adsorb the gold-cyanide complex from the solution through a process called carbon adsorption. The loaded carbon is then sent to an elution circuit where the gold is desorbed from the carbon. The gold-laden solution obtained is further processed to recover the metallic gold through precipitation or electro-winning. This intricate process ensures efficient recovery of gold from its ores and is widely used in the mining industry to extract this precious metal.
