Automation & Control

ISA Show Preview

    ISA Expo, the largest automation and control exhibition in North America, will return to Houston’s Reliant Center on October 2–4. The Instrumentation, Systems and Automation Society (ISA, Research Triangle Park, N.C.) hosts this exhibition of automation and control…

Multivariable Control

    Multivariable (MV) control is a powerful technology. Applied in industry for several decades now, substantial benefits from its use have been reported in many publications. Yet, this technique is still by far not utilized to the extent it…

Combustion models for alternative fuels

Computer models that simulate the operation of jet engines with alternative fuels will be developed by Reaction Design (San Diego, Calif.; edlinks.chemengonline.com/6898-532) under a two-year contract with the National Aeronautics and Space Administration (NASA; Glenn Research Center). The objective is…

Engineering Software Makes the Leap From the Masters to the Masses

    Gone are the days of one-size-fits-all engineering software packages. Today, solution providers offer versions with improved integration for advanced data sharing and simplified user interfaces with the ability to multitask between the design house and the plant floor,…

VLE Calculations in Multicomponent Systems

    In multicomponent systems, equation-of-state (EOS) methods generally do a good job of determining vapor-phase properties. But accurate determination of properties for the liquid phase is much more difficult, especially when the liquid contains dissimilar molecules, polar molecules such…

Interoperability

The ST 3000 Pressure Transmitter line from Honeywell International, Inc. (Phoenix, Ariz.; edlinks.chemengonline.com/6897-546) is said to be the process industries’ first to support HART 6, the latest digital-communication protocol of the HART Communications Foundation (Austin, Tex.). The new interoperability gives…

Flowmeters Meet Modern Challenges

    Deregulation of market pricing structures, increased oil-and-gas exploration and drilling costs, fierce competition, and new regulatory requirements have all influenced today’s trend toward quality flow-measurement methodologies. Not only is volume a consideration, but so is the inherent value…

This ‘runny nose’ works better than a dry one

Researchers at the University of Warwick (edlinks.chemengonline.com/6896-540) and Leicester University (both U.K.) have used artificial nasal mucus to significantly enhance the performance of odor-sensing devices (electronic noses), which are used for quality control in, for example, the food industry. By…

A new NDT for composites

NASA Goddard Space Flight Center (Greenbelt, Md.; edlinks.chemengonline.com/6896-541) invites companies to license a new non-destructive test (NDT) method for evaluating the degree of cure, variations in chemical composition and defect states in resin-based composites and metal oxides — data that…

Food-contamination sensors

Scientists at the Universitat Autònoma de Barcelona (UAB; Spain; edlinks.chemengonline.com/6896-542), in cooperation with the Institute of Chemical and Environmental Research (CSIC), have developed an electrochemical biosensor that can detect atrazine — a widely-used herbicide — at levels of 0.005 µg/L,…
