Inside the Chinese Boom in Corporate Espionage from Bloomberg Businessweek By Michael Riley and Ashlee Vance on March 15, 2012 Last June, three men squeezed inside a wind turbine in China’s Gobi Desert. They were employees of American Superconductor Corp. (AMSC), a Devens (Mass.)-based maker of computer systems that serve as the electronic brains of […]
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 […]

Digital Insights: The iPad Hits the Plant Floor Companies like Pfizer have reduced time and increased efficiency by putting Apple’s most recent showstopper, the iPad, to use in manufacturing. From PharmaManufacturing.com
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.
