The widespread use of advanced control and process automation for biochemical applications has been lagging as compared with industries such as refining and petrochemicals whose feedstocks are relatively easy to characterize and whose chemistry is well understood and whose measure￾ments are relatively

Environmental laws and regulations including permits are reviewed in this chapter. Included are the Federal Clean Air Act Amendment (CAAA), the Federal Clean Water Act (CWA) regulations, the Resource Conservation and Recovery Act (RCRA) or, as it is also known, the Solid Waste Disposal

The solids-liquid separation process can be accomplished by filtration or centrifugation. Centrifuges magnify the force of gravity to separate phases, solids from liquids or one liquid from another. There are two general types of centrifuges: Sedimentation Centrifuges-where a heavy phase settles out from a lighter phase

n 1850 Thompson['] reported the first ion exchange applications which used naturally occurring clays. However, ion exchange resins have only been used in biochemical and fermentation product recovery since the

must also consider heating andor cooling requirements as well as to deliver the desired head pressure to overcome hydraulic pressure drop. Operating costs must also consider equipment maintenance, cost of cleaning chemicals and labor costs
