    摘要: There has been a surge in usage of biotherapeutic products in multiple industries. The biotherapeutic products are a mixture of their charge variants which are separated by a continuous chromatography process. This disclosure provides a method and an apparatus for control and optimization of the continuous chromatography process. The present disclosure helps controlling composition of charge variants in biotherapeutic products by developing an apparatus that has unique architecture including advanced Distributed Control System (DCS), programmable logic controllers (PLCs), Local area network (LAN) setup and Python layer with user interface. This allows an operator to monitor charge variant concentrations and obtain an optimal schedule to implement such that a target product composition is achieved. The present disclosure comprises a data-pre-processing step followed by prediction of process parameters using soft sensor and prediction models. The chromatography process is optimized to achieve targeted purity and yield by recommending optimal values of manipulated variables.

    摘要: A method of radionuclide waste extraction includes directing a waste stream from an upstream segment of a main waste pathway into a waste stream input of an anion exchange column, wherein the waste stream comprises uranium and a target radionuclide, the anion exchange column houses an anion exchange resin, a cation exchange column housing a cation exchange resin is fluidly coupled to the anion exchange column downstream the anion exchange column, and a sluicing preparation tank is fluidly coupled to the anion exchange column. The method further includes adsorbing uranium from the waste stream onto an anion exchange resin, directing the waste stream from the anion exchange column into the cation exchange column, adsorbing the radionuclide onto the cation exchange resin, removing spent anion exchange resin from the anion exchange column, and directing fresh anion exchange resin from the sluicing preparation tank into the anion exchange column.
