Structured packing is specifically designed and arranged and neatly piled in the packed tower scrubber. The uniform arrangement of durable structured packing provides many advantages compared to random packing. Structured packing is more expensive, yet offers higher efficiency, lower energy consumption, increased capacity, as well as lower pressure drop. All of these will lead to increased operating rates and lower down time.
With a history that dates to the early 1800’s, random packing also known as dumped packing is one of the primary cost-effective devices used in mass and heat transfer. It is the practice of dumping filtration material into a column in the packed tower scrubber. This process is achieved during installation, at which point the packing is allowed to fall in random. Advantages include low pressure drop and reduction of liquid holdup.
