Continuous moving bed with advanced design concepts and superb production process. It is suitable for a small amount of product preparation and process technology development, wide range of uses. It is easy to operate and can be based on different product separation requirements flexible adjustment process. It can be used as a continuous ion exchange or continuous chromatographic separation applications.
Advantages of continuous moving bed
l Integration of all the steps can be continuous operation, and the system matching is strong;
l Significantly reduce the amount of resin, and give full play to the use of resin potential;
l Extend the service life of the resin;
l Reduce water and chemical consumption, significantly reduce operating costs and reduce sewage emissions;
l Remove or separate substances with different characteristics, which can simplify a complex process;
l Maintain the stability of the product composition and concentration in the feed liquid;
l Effectively improve the purity and concentration of product liquid, saving the cost of follow-up technology;
l The use of multi-column system, can be flexible to change the production process;
l Compact, small footprint, easy to install in any location;
l Fully automated, programmed operation control, to ensure continuous and stable operation of the equipment; and
l Flexibility to adjust the rotation speed or adjust the flow rate according to the process.
Continuous moving bed can be applied to continuous ion exchange and continuous chromatographic separation
Continuous ion exchange principle:
Ion exchange technology is based on resin functional groups and materials in the adsorption of specific ions carried out by the exchange process. Iion exchange is a reversible equivalent equivalent exchange reaction. Traditional ion exchange applications uses a fixed bed to achieve, our analysis of the work of the fixed bed indicate that the resin bed can be divided into three sections during the exchange process namely the saturated zone, the active zone (mass transfer zone) and the fresh resin zone. As the exchange progresses, the mass transfer zone continues to move down until the bottom exchange is complete. In the entire process only the mass transfer zone is in working condition, saturated area and fresh resin area are idle, so the resin utilization rate is low. In order to improve the utilization of resin, we transfer the mass transfer area into several small units. Once the above small units are saturated, they are removed for washing and regeneration, the fresh resin unit for processing is returned to the bottom of the mass transfer zone, which greatly improves the utilization of the resin.
