The invention relates to a process and a device using CO cryogenic distillation separation of stable isotope 13C, the device for cascade column cryogenic rectification tower, regular packing, condenser and reboiler, scrambler, liquid nitrogen isotope composition of the circulatory system, the level of cascade power transmission tower multi cascade, high purity CO by distillation as a part of the top of the tower, spray liquid, the other part into the distillation tower at a lower level, and then by isotope scrambling transformation, 13C16O transformation and 12C18O isotope. The invention provides a simple process, low production cost, step 99% stable isotope 13C production method and save energy, but also avoid the disadvantages caused by the plant shut down equipment failure, the level of the cascade and adopting corrugated structured packing reduces the engineering problem of traditional technology blindly pursue high brings, overcome the defects and toxic reaction speed of the traditional chemical method is slow, low production capacity.
【技术实现步骤摘要】
本专利技术涉及一种分离稳定同位素13c的工艺及装置，尤其是涉及采用co低温精馏 分离稳定同位素13c的工艺及装置。
技术介绍
在现有技术中，已有采用CO低温精馏分离稳定同位素13C的工艺及装置。 1947年美国Eastman Kodak公司采用毒性极强的HCN/NaCN化学交换法(Clyde A. Hutchison, David W. Stewart, Harold C. Urey， the concentration of 13C， Journal of chemical physics, Vol. 8， 1940， 532-537)，进行半工业化生产65% "C，后被勒令关闭。 在20世纪60年代，美国用CH4热扩散法生产13C(W. M. Rutherford, J. M. Keller, Preparation of highly enriched carbon-13 by thermal diffusion of meth肌e， the journal ofchemical physics, Vol. 44， No. 2， 1966， 723);...
【技术保护点】
一种采用ＣＯ低温精馏分离稳定同位素［１３］↑Ｃ的工艺，其特征在于，该工艺包括以下步骤：高纯ＣＯ经精馏塔精馏后，一部分作为塔顶喷淋液，另一部分进入下一级精馏塔，精馏后的ＣＯ经同位素扰频器转化，实现［１３］↑Ｃ［１６］↑Ｏ和［１２］↑Ｃ［１８］↑Ｏ同位素转化，得到［１３］↑Ｃ产品。
