The paper presents theoretical and experimental data concerning mass and heat transfer on B7 structured packing, used for deuterium separation in distillation column. The first section of the paper is dedicated to mass transfer study for hydrogen distillation, and the second section to mass and heat transfer for water distillation. Mathematical model verification was carried out with experimental data, obtained from two laboratory distillation plants for deuterium separation. The experimental data concerning B7 ordered packing efficiency for hydrogen cryogenic distillation at about –250 °C level were obtained from the first plant, and the second plant provided data concerning mass and heat transfer on the same packing for deuterium separation by water vacuum distillation at about 60 °C level. Height of transfer unit and mass and heat transfer coefficients, evaluated theoretically and experimentally, are comparable with those from chemical industry separation processes. This fact justifies the use of multi-tubular column model or transfer process description at distillation column equipped with B7 structured packing
