Dow offers numerous process technologies for the purification of chemical compounds. These include distillation, crystallization, stripping, extraction, filtration, chromatography, adsorption and ion exchange.
Ion exchange resins and polymeric adsorbents have found wide use in the basic chemicals and petrochemicals industry as an economical means of separating and purifying a large number of different compounds or process streams.
Chemical Processing Applications
BRINE SOFTENINGIn general, the brine purification steps include: saturation, precipitation, clarification, filtration, selective ion exchange, electrolysis and dechlorination. If the salt is already of high purity, such as vacuum salt, only a secondary purification with ion exchange is required. |
PURIFICATIONMany different process technologies are available for the purification of chemical compounds. Ion exchange resins and polymeric adsorbents have found wide use in the basic chemicals and petrochemicals industry as an economical means of separating and purifying a large number of different compounds or process streams. In some cases, ion exchange is the only technology available that can produce the desired levels of purity. |
RECOVERYIon exchange resins and polymeric adsorbents have helped to recover valuable metals to non-detectable levels and recycle metals such as lead, copper, nickel, silver and zinc. This optimizes manufacturing processes and minimizes waste handling. |
REMOVALA new portfolio of products from Dow Water & Process Solutions offers options for removing a wide variety of trace contaminants. Specialists at Dow can work with you to design a system based on your specific needs - whether you need removal of a single contaminant or a particular combination of contaminants. |
