Designing Polymerization Reaction Systems | AIChE

Polymerization reactors are rarely built to make only one product over the entire life of the equipment. Normally, a reactor switches among a handful of products. In addition, markets change, so manufacturers prefer a flexible design — one that is good today, and, with little or no modification, 30 years from now. Reactor configuration.
