Design study for experimental system of hydrogen/deuterium distillation

A design study has been performed for an experimental system of hydrogen/deuterium distillation. The major purpose of the experiment are to study separation characteristics of the column, to measure some fundamental parameters (e.g. HETP, flooding velocity, liquid holdups and pressure drop), and to establish design methods for principal components such as the condenser, packed column, reboiler, heat exchangers and vacuum jacket. The major items in the design study are to draw a flow schematic of the system, to make design calculations for the components, to determine their structures, to examine operation and control modes, and to list up instrumental equipments. Above all, our most significant concern is to study the heat balance for the whole system including the refrigerator. (author)
