The Advantages of a Metal Pall Ring
A Metal Pall Ring is the world’s most popular random packing type. It is the improved design of the Raschig ring and provides a significant performance increase, as well as reducing pressure drop.
It can be made from ceramic, plastic, or metal depending on the requirements of the system. Its open, cross-linked design allows for highly efficient use of the ring’s surface area.
This makes it a versatile alternative to metal pall rings. It is widely used for absorption, scrubbing, and stripping services in various industries including oil and gas, petrochemical, coal, and other fuels and power plants.
The advantages of this type of random packing include a high capacity for loading and transmission, low-pressure drop, good gas-liquid distribution, and high mass transfer efficiency. It is also mechanically robust and has a reduced probability of breakage.
Typical applications for this type of random packing include absorption towers, constant decompress towers, compounding ammonia plants, decarbonization and desulfuration plant, separation of ethylbenzene, and separation of isooctane/ methylbenzene.
A Metal Pall ring is made from carbon steel, galvanized or stainless steel. It has two layers of windows on the cylinder wall and five ligules that bend inward to the ring axis. It is available in different sizes and is suitable for hostile environments where corrosion and rust are likely to occur.
This type of random packing can be applied in all types of separation, absorption, and decompression towers at atmospheric pressure and under vacuum where a low-pressure drop is critical. It is also widely used in steam stripping towers, quench towers, and direct contact cooling applications.
It can be customized to meet the needs of any industry. It has excellent resistance to acid, alkali, and salty chemicals, as well as temperature stability. It is also more resistant to corrosion and rust compared with plastic or ceramic pall rings.
Haiyan Weijia Special Steel Co., Ltd. offers various kinds of Metal Pall Rings of different sizes and construction. Whether you are in need of a single ring or a complete set, we can help you find the best solution for your application.
The advantages of this type of ring include the ability to reduce pressure drop, higher capacity, and lower resistance than ceramic. It is also chemically resistant and can handle corrosive fluids.
This is a versatile type of random packing that is available in many different sizes and designs to suit the requirements of any application. It can be used in all types of separation, absorption, and separating towers at atmospheric pressure and under vacuum where the pressure drop is critical to the performance of the system.
It is a metal random packing that has a similar cylindrical dimension as the raschig ring but is adjusted with two rows of punched and formed fingers that facilitates vapor flow. This adjustment can increase the performance of the ring by up to 50 percent, as well as reduce the pressure drop through the column.
It can be used in all types of separation, absorb plants, constant decompress tower plants, compounding ammonia plants, decarbonization & desulfuration plants, separation of ethylbenzene, and separation of isooctane/methylbenzene.
