Boiler Dissolved Oxygen Control

by IC Controls Ltd.  (May 20, 2015)

DISSOLVED OXYGEN CHEMISTRY Dissolved Oxygen (DO) is a measure of the amount of oxygen, usually thought of as a gas, that is dissolved in a liquid such as water. Oxygen is essential to life and is also the most common element found taking part in corrosion reactions. DO can be thought of as the fuel needed for the corrosion process to proceed. It ...

Low level moisture measurement in Natural gas using a Lunable diode laser absorption spectroscopy (tdlas) based laser case study

by Ametek Process Instruments - THERMOX  (Nov. 24, 2014)

Introduction The measurement of water vapor in natural gas has long been of industrial importance, and has been addressed by a variety of analytical techniques over the years. Chief among these techniques has been the quartz crystal microbalance (QCM) based analyzers. The QCM technology is still the workhorse for production and pipeline ...

Monitoring landfill gas

by Geotech  (Nov. 23, 2011)

Infrared absorption Infrared absorption is usually the preferred method for measuring methane and carbon dioxide. Most gases absorb radiation in the infrared region. The wavelength of radiation that is absorbed is determined by the natural vibration frequencies of the molecule. These natural frequencies will depend on several factors. Thus ...

Mercury and other trace elements in Ohio River fish collected near coal‐fired power plants: Interspecific patterns and consideration of consumption risks

by John Wiley & Sons, Ltd.  (Jan. 14, 2015)

Many coal‐fired electric generating facilities in the US are discharging higher loads of Hg, Se, and other chemicals to receiving streams due to the installation of flue gas desulfurization (FGD) air pollution control units. There are regulatory concerns about the potential increased uptake of these bioaccumulative trace elements into food ...
