Energy Newsbriefs Blog

This current awareness service is prepared by the WSU Energy Program Library with funding from the U.S. Department of Energy State Energy Program. This information is provided for energy professionals and interested members of the public to highlight recent energy-related news, articles, and reports that discuss energy efficiency, energy conservation, and renewable sources of energy in engineering and policy circles.

 


Terminology: Energy & Power

Heating, Plumbing, Air Conditioning (HPAC), Aug. 2014, by John Siegenthaler.

"Most HPAC readers deal with units such as Btu/hr, kilowatts, °C and many others on a daily basis. For the most part, you use valid units to describe physical quantities. For example, you know that flow rate is measured in gallon per minute (gpm), and not gallons. You also know that temperature is expressed in °C or °F, and not in therms. However, when it comes to the difference between energy and power, our industry tends to get sloppy with its terminology."

"Using laws of thermodynamic analysis to evaluate the energy and power characteristics of wastewater and beneficial uses of biogas offers greater insight into best business practices and what is achievable."

Case Study: Insulation Audit Leads to Big Savings [Chemical Plant]

Insulation Outlook, Aug. 2014, by Zach Tanghetti.

"Honeywell's Geismar site was established in 1967 and is currently operated by roughly 275 employees and 130 contractors. The site is responsible for producing multiple refrigerants, hydrofluoric acid, and a resin that is used in medical packaging. The various reactors, heat exchangers, steam traps, and process piping that make our processes a reality all utilize insulation to maintain temperatures and moderate processes. All of our processes are susceptible to inefficiencies because systems that include insulation can degrade in a chemical plant environment. When insulation degrades, it loses its ability to retain heat within the system. Though the site is in Louisiana, winters can still be cold, and steam and other process lines have even been known to freeze in the past. Improved repair and maintenance of insulation systems could have helped prevent these process upsets."

"First of Three Parts - Power factor (PF) is an important component of an alternating current (AC) circuit, but understanding its actual effect can be difficult. Why is PF mysterious to many of us? It has to do with the way it is explained."
