AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively address issues such as tower structure stability, liquid transport, pressure management, energy consumption, liquid level control, temperature gradient changes, and thermal insulation in the production of boron-10 isotopes using cryogenic distillation at the industrial level, resulting in the failure to achieve industrial-scale production of cryogenic distillation in China.

Method used

A cascaded distillation system is adopted, which reduces the height of a single cryogenic distillation column by assembling multiple distillation units with smaller heights and combining vertical and horizontal cascading methods. Vacuum insulation and multi-stage vacuum hoods are used for thermal insulation, and the layout of the condenser and reboiler is optimized.

Benefits of technology

This effectively reduces the requirements for tower structural stability, liquid transfer, pressure management, energy consumption, and temperature gradient changes, enabling the industrial application of cryogenic distillation and filling the gap in domestic cryogenic distillation for the production of boron-10 isotopes.
