ChemicalChemical reactors

Chemical, polymerization and pharmaceutical processes utilize reactor vessels to contain chemical reactions. Chemical reaction speed and product quality are frequently controlled by an external heat exchanger for elevating temperature and a cryogenic system for lowering temperature. Reactors typically contain impellers for product mixing.

Challenge

Level instrumentation in a tank-type reactor vessel must contend with diverse and often aggressive product chemistries, agitation, mixing, surface foam and temperature and pressure variations. Low level monitoring in the discharge line, high level monitoring in the vessel, and interfacial measurement of the foam/emulsion interface is recommended.
