Among the various methods for the separation of stable hydrogen isotopes, water distillation, despite the low separation factor, has many inherent advantages, including the absence of toxic and corrosive components of hydrogen sulfide gas, no need to use electrolysis to convert hydrogen gas to water and no need to catalyst. In this research, batch distillation in packed tower with polyamide Rashig rings and pseudo Dixon rings were made of stainless steel was used to produce heavy water and Height Equivalent to a Theoretical Plate (HETP) was obtained. Although this height was lower for polyamide packing, it was rejected due to increasing the total organic carbon (TOC) of water. Next, for the pseudo Dixon packing in the linear part of the diagram, which is optimal for designing operational units, a mathematical model was fitted to the test data, that can be used for prediction among the test interval, with very good aquracy.
