High efficiency: Structured packing provides high mass transfer efficiency due to its high surface area and low resistance to vapor and liquid flow. This results in better separation performance and higher purity product streams. Low pressure drop: The pressure drop across structured packing is generally lower than that of other packing types, resulting in lower energy consumption and operating costs. Low liquid holdup: Structured packing has a lower liquid holdup than random packing, which reduces the risk of flooding and increases the stability of the column operation. Wide range of applications: Structured packing can be used for a wide range of separation processes, including high vacuum, azeotropic, and extractive distillation. High cost: Structured packing can be more expensive than other types of packing due to its complex manufacturing process and use of high-quality materials. Limited flexibility: Structured packing is generally less flexible than other packing types and may require custom designs for specific applications. Sensitivity to fouling: Structured packing is more sensitive to fouling than other types of packing, which can reduce its separation efficiency over time. Difficult to clean: Structured packing is difficult to clean due to its complex geometry, which can lead to reduced efficiency and increased maintenance costs.
