  • Save a bundle solving pressure-drop problems

    Pressure drop in compressor-suction and interstage coolers often creates problems. In some cases, just a few pounds of extra pressure drop make a revamp unworkable.

  • Keep temperature control out of hot water

    Readers offer tips about how to control the temperature of a water stream. (From the Process Puzzler column in November 2004 Chemical Processing magazine.)

  • Process integration extends its reach

    Thousands of successful applications worldwide testify to the value of process integration technology in reducing energy costs and increasing capacity through debottlenecking.

  • Better damper control delivers big savings

    Installing an electric drive on a steam boiler damper results in lower fuel consumption. The reason? The electric drive enables boiler operation with just the right amount of excess air at lower firing rates.

  • Put Your Column on the Map

    Residue curve maps (RCMs) can be employed in a variety of ways, including system visualization, evluation of data, and process synthesis, modeling and troubleshooting

  • Order up better measurements

    Second-order instruments can provide improved accuracy and reliability for electrochemical and other sensors.

  • Adaptive control takes a leap forward

    The next generation of adaptive controllers will identify a process model quickly and automatically and provide process model parameters that can be displayed, trended and diagnosed.

  • Get Control of Reactor Temperatures

    A reader has a plug-flow reactor whose temperature is starting to cycle. The company tried to tuning both controllers but saw no improvement. Read about potential solutions to this reader's problem.

  • Energy savings are in the air

    Anywhere compressed air can be eliminated represents an opportunity to reduce system operating expenses. Often, this reduction means fewer compressors must operate to meet the plant's air requirements.

  • Sidestep side-draw control surprises

    The simplest approach to control side-draw distillation columns uses flow control on the side product. This solution, however, is not ideal for all side-draw control situations.
