Heat transfer processes investigation for hydrogen in cryogenic distillation plants

One of the main problems of the hydrogen isotopes separation by cryogenic distillation is holding a constant temperature of the condenser fitted within the distillation column. This can be achieved by an optimal design of the cryogenic cycles. The present study is focused on experimental investigation of heat transfer processes that take place in different types of heat exchangers operated at low temperature. For the next step we will have to design a cryogenic cycle for the cooling of the condenser with which a cryogenic distillation column for hydrogen isotopes is equipped . (authors)
