Key innovations
The innovation of this green technology lies in its unique solvent-free membrane crystallization separation process, which achieves crystallization on the tube wall and solid-liquid phase equilibrium, thereby avoiding environmental pollution and energy consumption associated with solvent use. Compared to traditional distillation, its overall energy consumption is only 10-30%, and it effectively reduces losses of heat-sensitive substances.
Potential economic benefits
It significantly reduces energy consumption, floor space requirements, and solvent costs, improves product purity and yield, enables efficient and stable production, and greatly enhances economic benefits.
Potential climate benefits
This technology does not involve solvents, thus avoiding the energy needed for solvent recovery. Its energy consumption is only 10-30% of that in traditional distillation, which greatly reduces production energy use and carbon emissions. At the same time, it increases yield and product purity, minimizing resource waste and the energy required for waste treatment. The reduced floor space also indirectly lowers the carbon footprint of infrastructure.
Solution details
The material is uniformly coated on the pipe wall for crystallization. By leveraging the differences in melting points of various substances and achieving solid-liquid phase equilibrium, the main substance is separated from impurities. No solvent is added during this separation process, avoiding environmental pollution and energy consumption associated with solvent recovery, thereby addressing the challenges of high energy consumption and unstable quality in the production of high-purity chemicals.
No solvent is involved; the capacity of a single unit is 3,000–100,000 tons per year; operating temperature ranges from -20°C to 200°C; product purity is 98–99.999%; the highest yield can reach 99.5%.
The overall energy consumption is 10-30% lower than that of traditional distillation processes; the land area required is reduced by 30%; low-temperature separation minimizes losses of heat-sensitive substances, improving overall yield; the product quality remains stable, and product specifications can be adjusted flexibly.
