Mass transfer method, structured packing and mass transfer device for a reduced fluid load

摘要

Material exchange method comprises supplying a first fluid and a second fluid in a material exchange apparatus comprising a container having a head region, a bottom region and a material exchange region. The first fluid is contacted with the second fluid at least in the material exchange region. The material exchange region is arranged between the head region and the bottom region. The material exchange region comprises a structured packing comprising many mutually adjacent layers of a fabric with fiber strands from a non-metallic material. Material exchange method comprises supplying a first fluid and a second fluid in a material exchange apparatus comprising a container having a head region, a bottom region and a material exchange region. The first fluid is contacted with the second fluid at least in the material exchange region. The material exchange region is arranged between the head region and the bottom region. The material exchange region comprises a structured packing comprising many mutually adjacent layers of a fabric with fiber strands from a non-metallic material. The material exchange apparatus is operated with a liquid loading of not 3 m 3/m 2hour. Independent claims are also included for: (1) the structured packing for the material exchange apparatus with the head region and the bottom region, comprising many mutually adjacent layers that form an upper side facing the head region and a bottom side facing the bottom region, where (a) the layer exhibits a wall element that extends between the top and bottom sides, and (b) the wall element is formed as the fabric comprising fiber strands of the non-metallic material that is designed as weft thread comprising a thread count of at least 100 g/1000 m and at least 20 threads/25.4 mm; and (2) the material exchange apparatus comprising the structured packing.
