Overview: Mean time between failure is a reliable term used loosely throughout many industries and has become widely abused in some. Over the years the original meaning of this term has been altered which has led to confusion and cynicism. MTBF is largely based on assumptions and definition of failure and attention to these details […]
Chemical
from Modeling and Control by Greg McMillan 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.

To achieve best overall plant operation, it is often necessary to coordinate the operation of equipment in multiple process areas. In Chapter 16 of Control Loop Foundation – Batch and Continuous Processes, some examples are given where multi-loop techniques may be effectively used for such coordination. One of the examples from this chapter is power […]
IT can help create a secure network connection to the industrial plant floor. It can be ideal for a machine builder to monitor and connect to a piece of equipment in a plant remotely. However, how many machine builders have tried to cross that invisible barrier? As soon as you mention you want to open […]
A continuous chemical reactor process is characterized by the continuous feed of two or more chemical reactants and a continuous output flow of product. To achieve the desired product specifications, the proportions of each reactant must be tightly maintained at a target value using ratio control. The chemical reaction that occurs within the reactor is […]
Just Like Distributed Control, Distributed Safety Is Coming Soon to a Process Plant Near You, Maybe Your Own In the beginning, all control was distributed in the field near each particular process. Much of this control was manual, with islands of pneumatic-based automation. Then came the inaptly named “distributed control system,” which was, in […]
