Absorption efficiency packing HETP

Most of the experimental work on the efficiency of structured packings has been performed in a distillation mode. The HETP values for these packings are discussed in detail in Chapters 7, 8, and 9. Meier et al reported on the absorption of 1,600 ppm SO2 from air into water at atmospheric pressure using Mellapak 250Y packing [6]. They found HTU values for this structured packing were 33 to 44% lower than for 2-in. metal Pall rings at liquid rates of 16 to 25 gpm/ft. ... [Pg.44]

Packed columns maintain a high separation efficiency in both liquid-film-controlled and gas-film-controlled systems. For many years, packed columns have been used for absorption systems that characteristically are liquid-film-controlled. As an example, the HETP value for a trayed column might be twice as great in an absorption operation as compared to a distillation operation. For the same systems, the HETP value for IMTP packing in the absorption operation typically would be only one-third greater than for the distillation operation. [Pg.202]
