Advanced Controls Yield Major [Food] Process Improvements

Food Engineering, Mar. 2017, by Wayne Labs.

"You think your dairy processing plant is efficient, but when you do the math, you can’t account for 7 million pounds of lost milk per year. That’s a loss of more than $1 million. In addition, your POTW is billing you more than $80,000 annually for exceeding the maximum permitted levels of fats, oils and greases (FOG) in your wastewater. What’s going on? Seems like money down the drain, doesn’t it? ...Fortunately, this story has a happy ending. Vigilistics, Inc. (now part of SafetyChain Software) production management software was employed to get a handle on what was happening to the “spilt milk."

A Cheaper HRSG [Heat Recovery Steam Generator] with Advanced Gas Turbines

Power Engineering, Mar. 2017, by S. Can Gülen, Ilya Yarinovsky, and Dave Ugolini.
http://www.power-eng.com/articles/print/volume-121/issue-3/features/a-cheaper-hrsg-with-advanced-gas-turbines.html

"Present state-of-the-art in gas turbine combined cycle (GTCC) design is three-pressure, reheat (3P-RHT) steam bottoming cycle with steam generation at three different pressure levels. The goal is to maximize total steam generation and steam turbine generator power output for a given gas turbine exhaust energy and, thus, to maximize combined cycle efficiency."

Play Ball! American Baseball Stadiums Round the Bases on Energy Efficiency

U.S. Dept. of Energy, Apr. 3, 2017 by Jason Hartke.

"As Americans gear up to “root, root, root for the home team” on Major League Baseball’s (MLB’s) Opening Day, they might be too focused on the games to notice that their stadium is more efficient than it used to be. Professional ballparks average 1 million square feet and together host more than 73 million Americans each year – which means there are a lot of opportunities for improvements that enhance visitor experience, save stadium owners and operators money, and reduce energy and water use."

Taming the Power-Hungry Beast [Motors in Ethanol Operations]

"IoT information allows end users to provide corrective action that serves a proactive purpose, rather than reactive."

Cooling Towers Offer Data Centers Water and Energy Savings

Chiller & Cooling Best Practices, Mar. 2017, by Douglas Bougher and Kent Martens.
http://www.coolingbestpractices.com/technology/cooling-towers/cooling-towers-offer-data-centers-water-and-energy-savings

"The number of data centers in the United States continues to grow in response to the enormous amount of digital information stored and streamed. The massive computer power within these data centers generates heat, making efficient cooling a key building system requirement. Evaporative cooling towers are an integral part of many data center cooling systems. Recently some have questioned the use of cooling towers, citing water scarcity to bolster their arguments. But a thorough examination of water use for local onsite cooling towers compared to water use to generate power at regional fossil fuel power plants reveals surprising results."

Compressed Air System Commissioning Part 2: Measurement and Data Plots

Compressed Air Best Practices, Mar. 2017, by Tim Dugan.

"Facility managers, air compressor dealer personnel, auditors and utility DSM energy engineers: All three project stakeholders need to have one agreed-upon robust methodology for commissioning a system, and the teamwork to do it correctly the first time.  That is the intent of this series of articles."

More End Users Embracing Smart Pumping Applications

"The Industrial Internet of Things (IIoT) is a business buzzword. But asking 10 people for a definition of IIoT will likely result in 10 different answers. Additionally, many may think IIoT refers to connecting people with machines, instead of a connected process. This concept goes beyond basic process management to informing and educating people on what is happening in a process. Further, some people who mention machines often think of industrial applications, such as packaging or conveying equipment. Pumping systems and pumping applications are often left out of the discussion."

Plastic Extruder Reduces Compressed Air Use by 367 cfm

Compressed Air Best Practices, Mar. 2017, by Don van Ormer.

"A plastic product manufacturer spends an estimated $245,000 annually on electricity to operate the air compressors in a compressed air system at its plant located in a midwestern U.S. state.  The main manufacturing process is plastic extruding. The current average electric rate, at this plant, is 7 cents per kWh. The compressed air system operates 8,760 hours per year and the load profile of this system is relatively stable during all shifts."

Microgrid Momentum: Building Efficient, Resilient Power

C2ES: Center for Climate and Energy Solutions, Mar. 2017, Doug Vine, et. al.
https://www.c2es.org/docUploads/microgrid-momentum-03-2017.pdf

"When Hurricane Sandy cut off power to millions of homes and businesses in the Northeast, a few areas, mostly parts of universities, kept the lights on using their own power generation systems. This ability to sustain electricity service during widespread natural disasters is one reason for the growing interest in microgrids. But they offer other important benefits as well. By increasing efficiency, integrating renewables, and helping manage energy supply and demand, microgrids can reduce greenhouse gas emissions and ave energy. For utilities, microgrids can ensure power reliability in remote areas. Microgrids also appeal to those who want to disconnect from utility bills."
