Features: Membrane separation is based on the principle of dissolution and diffusion of similar solubility, only physical changes in the separation process, without any chemical changes. Therefore, the membrane separation process is clean and environmentally friendly, and does not produce secondary pollution.
Advantage: The technical process design is simple, with less auxiliary equipment, and the operating energy consumption is only for the condenser and vacuum pump. The required condenser temperature does not need to be deep-cooled, according to the nature of the substance can be used circulating water or frozen brine. Membrane separation system is an open system, there is no hidden danger of organic gases due to phase change and heat generation during operation, and there is no danger of explosion due to sudden change of system pressure.
