This paper presents a design study of a cryogenic distillation column for hydrogen isotope separation. The column was modeled as a theoretical equilibrium-based stage column. Thermodynamic properties were evaluated with the Peng–Robinson Twu equation of state model. The liquid holdup and pressure drop of each theoretical stage were modeled with a general packed column model. The models were implemented in an equation-oriented optimization framework. The effects of parameters such as the number of theoretical stages, feed location, diameter, flow rate of the distillate, and condenser duty on the tritium inventory, total pressure drop, and product quality were investigated. An optimal design that minimizes the total amount of tritium in the liquid holdup under a tritium product quality constraint and non-flooding constraints is presented.

氢同位素分离系统低温精馏塔的设计研究

本文介绍了用于氢同位素分离的低温蒸馏塔的设计研究。该塔被建模为基于理论平衡的级塔。热力学性质用 Peng-Robinson Twu 状态方程模型进行评估。每个理论阶段的持液率和压降均采用通用填充塔模型进行建模。这些模型是在面向方程的优化框架中实现的。研究了理论级数、进料位置、直径、馏出物流量和冷凝器负荷等参数对氚库存、总压降和产品质量的影响。提出了一种优化设计,在氚产品质量约束和非溢流约束下最小化持液中的氚总量。
