为研究带侧线反馈的低温精馏氢同位素分离规律性,建立了带侧线反馈的低温精馏氢同位素分离计算方法,并以H2/HD/D2体系进行了计算分析。计算结果表明,侧线反馈对分离性能影响显著,再沸器中以D2为主,氘丰度可达到0.90,而无侧线反馈情况下,再沸器中以HD为主,氘丰度不超过0.50;有侧线反馈条件下,系统运行约40hHD向D2的转化达到峰值,而在无侧线情况下,HD浓缩在40h已达到饱和;当侧线采出比为...
低温精馏分离H2/HD
氢同位素分离 低温精馏 理论模型

以天然氢为原料的第一次实验,总理论塔板数在20左右,以氘丰度为1.0×10-3的原料气进行的第二次实验,总理论塔板数为24,理论等板高度在15~20 cm。实验表明,在总理论塔板数较小时,冷凝器中氘丰度将随时间增长,再沸器中氘丰度变化实验值与理论值吻合很好,但同时观察到实验过程中液氢液位、温度等运行参数存在扰动。
