Modular Valve System and its use in a method for producing chemical and pharmaceutical products with integrated multi-column chromatography

摘要

In a process to extract a chiral pharmaceutical agent, isomer or biomolecule from a mixture, the product is separated from the mixture by simulated moving bed technology contra-flow chromatography. In a process to extract a chiral pharmaceutical agent, isomer or biomolecule from a mixture, the product is separated from the mixture by simulated moving bed technology contra-flow chromatography. In the process the prior art 5-pump arrangement is replaced by a 4-pump arrangement. The process employs a single eluent constant flow feed pump and a single eluent compensation vessel and no circulation pump. The assembly employs no more than four pumps in the chromatography circuit. The prior art discharge pump, extract or refined discharge is replaced by a regulator valve. The automatic discharge of impure eluent in the circuit is facilitated by on-line detection and a regulator valve. Measurements made of the recyclate flow and the associated redundancy is increased by data comparison, increasing precision of the volumetric flow control. Independent claims are included for: (1) a modular valve system with a master plate, a valve housing, and a control unit housing, where the control system is located within an interior pneumatic chamber; and (2) a commensurate production process.
