The paper presents theoretical and experimental data concerning mass and heat transfer on B7 ordered packing, at deuterium separation by distillation. First section of paper is reserved for mass transfer study at hydrogen distillation, and second section for mass and heat transfer at water distillation. Mathematical model verification was carried out with experimental data, obtained from two laboratory distillation plants for deuterium separation. From first plant it was obtened experimental data concerning B7 ordered packing efficiency at hydrogen cryogenic distillation, at -250ºC level. With second plant it was obtened data concerning mass and heat transfer on the same packing, at deuterium separation by water vacuum distillation, at 60ºC level. HUT values, mass and heat transfer coefficients, evaluated theoretically and experimental, are comparable with those from chemical industry separation processes. This fact justifies the use of multi-tubular column model for transfer processes description at distillation column equipped with B7 structured packing.
