一种羰基镍精馏方法
摘要：
一种羰基镍精馏方法，涉及一种羰基镍精馏提纯的方法，其特征在于其精馏过程的是以热水浴间接加热的方式加热再沸器，进行精馏过程的热交换的。本发明的方法，采用热水浴间接加热的方式加热再沸器，水浴间接加热的热水的温度控制在72－85℃，再沸器温度控制在56－65℃，有效降低了羰基镍在加热装置上分解的速率，使生产可以长时间稳定运行，提高了生产效率，克服了精馏塔内壁的镀镍现象，有效延长了精馏塔的使用寿命。
摘要（英）：

The invention discloses a distillation method of carbonyl nickel, which relates to a method to distill and purify carbonyl nickel. The invention is characterized by the distillation course that: a reboiler is heated by indirect heating of hot water bath to carry out heat exchange during distillation course. The method of the invention heats the reboiler by indirect heating of hot water bath, the temperature of the hot water of indirect heating of hot water bath is controlled between 72 to 85 DEC C and the temperature of the reboiler is maintained between 56 to 65 DEG C, thereby effectively reducing the decomposition rate of carbonyl nickel in a heating device, ensuring the production to be stable for a long time, improving production efficiency, overcoming nickel plating on the inner wall of a distillation column and effectively prolonging the service life of the distillation column.
