Problems solved by technology

However, the industrial application of simulated moving bed chromatography technology is mainly limited to the separation of two-component systems. The industrial feasibility of simulated moving bed chromatography separation of multi-component systems needs to be further studied, and this technology still uses expensive fixed Phase, its adsorption capacity is low, and the sample processing capacity is not large

Abstract

The present invention relates to cross current solvent extractor, and is especially one continuous feeding, cross current extracting and chromatographically separating system. The system includes at least four continuous extractors; one network structure of the inlet and outlet pipelines; one material liquid pump; one water phase or heavy pump; one organic phase or light phase pump; one group of organic phase eluent acceptors; and one group of water phase eluent acceptors. The system has different material compositions and concentrations in different outlets so as to reach the aim of separating different kinds of material. The present invention has continuous feeding, great processing capacity, high separating selectivity and capacity of separating multiple kinds of material in mixture.

Description

technical field [0001] The invention relates to a cross-flow extraction device, in particular to a chromatographic separation technology and device suitable for high selectivity, large capacity, and continuous separation of a mixture containing two or more components, and is called a preparative continuous extraction device. Material cross-flow extraction chromatographic separation system. Background technique [0002] The separation of mixtures into individual pure substances is an important scientific research topic and the main research content of separation science. People have developed a variety of separation technologies. Among them, chromatographic separation technology has the advantages of good selectivity, high separation efficiency, low energy consumption, and can separate substances that are difficult to separate by traditional separation methods and heat-sensitive substances. It is widely used in chemistry, chemical industry, and medicine. and food industries....
