Batch vs. Continuous Control and Optimization – Part 4
Batch and fed-batch reactors are designed so that the product concentration is always increasing in the reaction phase of the cycle whereas continuous reactors are designed to hold a constant product concentration. These fundamental differences have enormous implications in terms of composition control. Conventional control of product concentration in a batch and fed-batch reactor is …

Batch vs. Continuous Control and Optimization – Part 3
Reactors are the pivotal unit operation that sets plant capacity and efficiency besides product quality. Reactors provide good examples of the common and distinctive opportunities for the PID control of batch, fed-batch, and continuous unit operations. Here we examine pressure, temperature, and endpoint control. The pressure control of batch, fed-batch, and continuous reactors may have …
