Abstract

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.

Description

Technical field [0001] A method for rectifying nickel carbonyl, which relates to a method for rectifying and purifying carbonyl nickel Background technique [0002] At present, in the rectification production process of nickel carbonyl, the reboiler is heated by direct steam heating. Due to the high temperature of the heating coil, part of the nickel carbonyl decomposes on the surface of the heating coil, and the nickel plating phenomenon of the heating device gradually increases. It makes it difficult for the production to run stably for a long time, which affects the production efficiency. On the other hand, the nickel plating on the inner wall of the rectification tower is also aggravated, resulting in a reduction in the service life of the rectification tower. Summary of the invention [0003] The purpose of the present invention is to solve the shortcomings of the prior art that the direct heating of steam causes the local temperature in the container to cause the serious n...
