In the chemical and pharmaceutical industry, a fast and efficient market launch is important to withstand global competition. Apart from the innovation of new products, the development of an appropriate production line is time-consuming. Modularization can accelerate the design and commissioning of a production plant. Herein, representative of a pharmaceutical process, the production, precisely the solid-liquid separation, of amino acids is considered. Therefore, the separation behavior of different amino acid systems and variations within solid systems are examined. With this information, a production plant is designed and differences regarding the amino acid systems are identified.
