Continuous Immobilized Enzyme Reactor - UMD

The main advantage of a continuous process over a batch process is the ease of automation and control. These modern engineering measures can lead to reduced operational cost and more consistent product quality. Despite the emphasis on enzyme immobilization, there are only a few established immobilized enzyme processes in industry.

Multiple continuous stirred tank reactors VS. Batch ...

A comparison of the performance of single CSTR and 2-CSTR systems against a stirred batch immobilized enzyme (IME) reactor has been made. When the downtimes in a batch reactor are not too small, the 2-CSTR system may become attractive and therefore a proper consideration should be given to the 2-CSTR system particularly when the application of a plug flow reactor is not practicable.
