Abstract:
An Introduction of the Importance of Separation Process and a New type of Separation - Continuous Multistage Countercurrent Fractional Crystallization(CMCFC)
Separation process plays an important role in both biological and chemical industry. For every biological or chemical reaction there must be several separation processes to pre-treat the feedstock and (or) to obtain the pure product(s). The capacity and efficiency of separation process may decide the benefit of a plant on a large extent. For example, the higher the separation efficiency, the higher quality and recovery rate, and the less energy consumption and drain to the environment. Several examples in these aspects are given.
Continuous multistage countercurrent fractional crystallization(CMCFC) is a new type and high efficiency separation technology. It can deliver many theory separation stages in a crystallizer column. In a column with 1000 mm crystal bed height, it can easily obtain the product purity as 99.999% under the feedstock concentration from 60%~95%. It can effectively avoid the decompounding of product because its operation temperature is under the melt point and less than that of distillation. It is also an energy saving process.
