Dana Jividen has been involved in a wide range of laboratory operations over his 20+ years at Union Carbide, Dow Chemical, and MATRIC. He also has experience in a variety of analytical techniques. Processes he has worked on include hydrogenation, ethoxylation, hydroformylation, carbonylation, and acrylic acid production. He has experience with heterogeneous, homogeneous, multiphase, and supercritical phase reactions, in Berty reactors, tube reactors, and CSTRs. He also has operating knowledge of process control systems.
Often chemical processes require an intermediate refining step to separate reaction products, and the physical properties of the components exclude typical separation unit operations such as distillation or extraction. Crystallization may be excluded because of uncertainties in the performance and/or reliability of the methodology. Let’s address the challenges (and solutions) of integrating crystallization techniques into processes where component yield and purity are the driving forces!
