  • Chemical makers play the power game

    Chemical manufacturers are using a range of strategies to cope with rising power costs. They are relying more on pooling and cogeneration.

  • Drive up energy efficiency

    The constant-speed approach to AC motors made a lot of sense when energy was cheap and drives technology was in its infancy. With their latest advances, adjustable speed drives can provide one of the best energy efficiency options for a plant.

  • Barriers to Industrial Energy Cost Control: The Competitor Within

    The Alliance to Save Energy conducts ongoing research of “the competitor within,” a.k.a. organizational barriers to energy efficiency. The barriers to energy management are rooted in the very complexity of modern organizations. Communications and incentives are the key to overcoming these barriers.

  • Process engineering: Dryer provides a concrete lesson in control

    Removing water or moisture from a liquid stream is a critical operation in many processes. Liquid stream dryers commonly contain either molecular sieves or adsorbents; during the last 20 years, the use of molecular sieves has become much more common.

  • 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.

  • 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.

  • 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.

  • Heat transfer fluids

    Information about heat transfer fluid (HTF) systems and the specifications for applicable fluids can be retrieved directly from the web sites of many HTF manufacturers
