The Chemical Industry Is Divided in 2 Parts, Low-Cost Commodity Providers and Providers of “Capability” From ControlGlobal.com By Aaron Hand If there were an award for most compelling session title at this week’s Emerson Exchange, it would probably go to Jos Berkien and Chris Hamlin, who put forth, “The Death of Quality and the […]
Herding Cats: Successfully Manage All Those Process Variables With a Systematic Approach to Plant-Wide Control From ControlGlobal.com By Sigurd Skogestad A chemical plant may have thousands of measurements and control loops. By the term “plant-wide control,” I do not mean the tuning and behavior of each of these loops, but rather the control philosophy of […]
by Greg McMillan 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. From Modeling and Control
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.
PlantServices.com By Plant Services Staff Honeywell’s 2011-12 Engineer of the Future Scholarship program will challenge Houston’s high school seniors to offer ideas for making industrial manufacturing facilities more energy efficient. The company is accepting applications from all Houston Independent School District seniors who are interested in pursuing engineering degrees from accredited universities. It’s the […]
by Greg McMillan Batch and continuous temperature loops can have vastly different responses. Fortunately, temperature loops have a characteristic early in the response that enables a fast identification of the process dynamics. The resulting models can be used for process control improvement, tuning, and rapid deployment of models for plantwide simulations. From Modeling and […]
by Greg McMillan Feedback control systems play an important role in batch and continuous unit operations. What are the similarities and differences in the process response, tuning, control strategies, and advanced process control opportunities? What can continuous control specialists learn from batch control experts and vice versa? Is it possible there are some fundamental principles […]
