YUHONG GROUP-Cyclone hopper (ASME SA516 Gr70 with SS 304H and 2205)   How it works :Cyclone separators work much like a centrifuge, but with a continuous feed of dirty air. In a cyclone separator, dirty flue gas is fed into a chamber. The inside of the chamber creates a spiral vortex, similar to a tornado. This spiral formation and the separation is shown in Figure 2. The lighter components of this gas have less inertia, so it is easier for them to be influenced by the vortex and travel up it. Contrarily, larger components of particulate matter have more inertia and are not as easily influenced by the vortex. Figure 1. A cyclone separator. Figure 2.      

YUHONG GROUP- Deaerator Tank ( ASME SA516 Gr. 70)   Water or any fluid which is used as a medium for heat transfer generally contains Oxygen and other non-condensable gases in it. These gases dissolved in a fluid act as insulation to heat transfer. Due to the presence of these gases in a fluid, heat transfer rates from fuel to fluid are generally reduced which in turn will increase the fuel required for heating, thereby decreasing the efficiency. In a deaerator tank ( Feed Water Tank), carbon dioxide (CO2), Non-dissolved Gas, and oxygen (O2) are released as gases and combined with water (H2O) to form carbonic acid, (H2CO3). Here are some of the benefits of using a deaerator tank: Reduces corrosion in steam boilers Improves the efficiency of steam boilers Increases the life of steam boilers Reduces the cost of operating steam boilers Improves the quality of steam Reduces the environmental impact of steam boilers

Yuhong Group Separator for hydrogen application   Hydrogen can be separated from gas mixtures using membranes and electrolysis. Membranes, particularly those made of palladium or its alloys, offer high selectivity and permeability for hydrogen. Electrolysis, using electricity to split water, is another method for producing hydrogen. Here's a more detailed breakdown:   1. Hydrogen Separation Membranes: Principle: These membranes are designed to selectively allow hydrogen to pass through while blocking other gases. Materials: Common materials include: Dense metal membranes: Palladium and its alloys are known for high hydrogen permeability and selectivity. Ceramic membranes: Inorganic microporous membranes offer advantages in terms of hydrogen flux and resistance to certain gases.  Polymer membranes: These can be used for specific applications where other membrane types are not suitable. Applications: Hydrogen separation membranes are used in various industries, including: Refineries: Recovering hydrogen from various process streams. Chemical processes: Purifying hydrogen for use in chemical synthesis. Natural gas processing: Separating hydrogen from natural gas mixtures. Ammonia and methanol production: Recycling and purifying hydrogen.   Advantages: High purity hydrogen: Can produce very high purity hydrogen (e.g., >99.999%). Energy efficiency: Can be more energy-efficient than other separation methods, especially when recovering hydrogen from low-concentration streams.   Disadvantages: Cost: Some membrane materials, like palladium, can be expensive. Sensitivity to certain gases: Metallic membranes can be susceptible to poisoning by gases like carbon monoxide and hydrogen sulfide.

YUHONG GROUP Ammonia Storage Tank For European Project Yuhong Group Finished a big project in Europe, the pressure vessel for Ammonia storage application.  Ammonia storage refers to the process and facilities used to store ammonia for various purposes, such as in the chemical industry, for agricultural use, or in refrigeration systems. Here is a detailed introduction: Storage Methods Pressurized Storage: Ammonia is stored under pressure to keep it in a liquid state. This is commonly done in cylindrical or spherical pressure vessels. The pressure required depends on the temperature and the desired storage conditions. For example, at room temperature, a pressure of about 1 - 1.5 MPa may be required to maintain ammonia in a liquid state. Refrigerated Storage: Ammonia can also be stored at lower temperatures to reduce the vapor pressure and make storage safer and more efficient. In refrigerated storage systems, ammonia is cooled to temperatures below its normal boiling point of -33.34 °C. This requires the use of refrigeration equipment to maintain the low temperatures. Storage Tanks Above - ground Tanks: These are commonly used for large - scale ammonia storage. They are usually made of steel and are designed to withstand the pressure and corrosive nature of ammonia. Above - ground tanks are easier to install, maintain, and inspect compared to underground tanks. They are often equipped with safety devices such as pressure relief valves, level indicators, and temperature sensors. Underground Tanks: Underground ammonia storage tanks offer some advantages in terms of safety and protection from external hazards. They are less likely to be affected by fires, explosions, or other surface - level incidents. However, they require more complex installation procedures and are more difficult to access for maintenance and inspection. Safety Considerations Leak Detection: Ammonia is a toxic and flammable gas, so detecting leaks promptly is crucial. Leak detection systems can use sensors to detect the presence of ammonia in the air or monitor changes in pressure, temperature, or other parameters that may indicate a leak. Ventilation: Adequate ventilation is necessary to prevent the buildup of ammonia vapors in the storage area. Ventilation systems should be designed to remove any leaked ammonia and maintain safe air quality levels. Fire Protection: Since ammonia is flammable, fire protection measures are essential. This includes the use of fire - resistant materials in the construction of the storage facility, the installation of fire suppression systems such as sprinklers or foam - based fire extinguishers, and the implementation of proper fire - prevention procedures. Emergency Response Plans: Facilities storing ammonia should have detailed emergency response plans in place. These plans should include procedures for dealing with leaks, fires, or other emergencies, as well as communication protocols to alert nearby communities and emergency services. Regulatory Requirements Environmental Regulations: The storage and handling of ammonia are subject to environmental regulations to prevent pollution. These regulations may limit the amount of ammonia that can be released into the environment, require proper disposal of waste ammonia, and mandate the use of environmentally friendly storage and handling practices. Occupational Safety Regulations: There are also regulations governing the safety of workers involved in the storage and handling of ammonia. These include requirements for personal protective equipment, training in safe handling procedures, and limits on the exposure of workers to ammonia vapors.
