  • Method of mass transfer for a small liquid load
    Patent number: 8936234
    Abstract: A method of mass transfer includes the steps of: supplying a first fluid and a second fluid into a mass transfer apparatus, wherein the mass transfer apparatus includes a vessel which has a head region, a base region and a mass transfer region, wherein the first fluid is brought into contact with the second fluid at least in the mass transfer region, wherein the mass transfer region is arranged between the head region and the base region and the mass transfer region includes a structured packing which includes a plurality of neighboring layers of fabric which includes fiber strands of a non-metallic material. The mass transfer apparatus is operated at a fluid load of at most 3 m3/m2/h. The fabric of the structured packing includes fiber strands of a non-metallic material which are formed as weft threads, wherein the weft threads have a yarn count of at least 100 g/1000 m and the weft threads include at least 20 yarns/25.4 mm.
