摘要： A method and apparatus (101) for the recovery of fat soluble compounds, such as beta carotene, is described. In one embodiment of the invention a solution (102) containing a fat soluble compound is passed through a fluidised bed (104) of crystalline metallic ore particles, such as magnetite, allowing the fat soluble compound to bind to the particles to form a complex (109). The fat soluble compound is released from the complex (109) by passing a wash solution (107) through the fluidised bed and subsequently collected in solution (108). The crystalline metallic ore particles may be reused.

摘要： A continuous Liquid-Solids Circulating Fluidized Bed (LSCFB) preferably for use as an ion exchanger consists of two fluidized bed columns, a fluidized bed adsorber (downer) operating in conventional fluidized bed mode for adsorption of ions of interest and a fluidized bed riser for desorption of ions (operating as a riser fluidized bed) to provide regenerated particles. Ion exchange particles circulate continuously between the riser and the downer i.e. the particles that have adsorbed ions in the absorber pass from the adsorber (downer) to the desorber where they are regenerated and the so regenerated particles are return to the adsorber near the top of the adsorber column. The LSCFB can be used in processes for continuous recovery of the ions of interest.

摘要： By regulating separation system's relative parameters, this broad and generalized separation process is disclosed to distinguish the fundament between this invention and chromatography for superior cost-effectiveness. A different mass transfer contacting method and differential set-up between two phases are applied on the disclosed apparatus to achieve purposed efficiency. This continuous separation process can be furnished as the integration of multiple partial fluidized beds or cells; operated under designated pressure level to instantaneous and simultaneous proceeding of determined mass-transfer phenomena. All zones within the process are simultaneously proceeded to isolate one product or multiple products from feed mixtures with other proceeding zones of feeding, impurity stripping, regeneration and washing. The differential mass transfer contact method is disclosed for efficient consumption of both solid phase and mobile phase. The unique recycling technique is disclosed to efficiently reuse the mobile phase and concentrate all isolated components within process. The liquid delivery module and holding tanks are illustrated for increasing operation efficiency and flexibility.
