Systems
Overview
Extraction describes a mass-transfer operation where a target substance in a mixture is transferred to a solvent (S). The basic principle of extraction is mixing and separation. The feed mixture consists of a carrier (C) and the target (T) substance. After mixing and separation, the target substance passes into the solvent, the extraction phase (S+T). The unloaded carrier phase is the raffinate phase (C).
Besides liquid-liquid extractions, solid-liquid extractions are commonly used for separation and purification in the pharmaceutical and chemical industries.
Extraction systems can be specifically designed for the specific needs of a client’s process. The layout is customized to ensure proper system functionality and to guarantee that all equipment and components are arrange for easy operation and maintenance.
Which kind of extraction systems are offered?
Pfaudler’s extraction units can be specified for liquid-liquid, such as extraction columns, mixer-settlers, and solid-liquid extractions.
The high-quality materials used allow Pfaudler to design individual units for the various requirements of laboratories and production. For example, Pfaudler can provide ATEX designs, as well as vessels in various sizes and materials, like borosilicate glass 3.3. or stainless steel with glass cover. Many other customizations and adjustments are also available.
