  2. Dissolved gas analysis - Wikipedia

    en.wikipedia.org/wiki/Dissolved_gas_analysis

    Dissolved gas analysis (DGA) is an examination of electrical transformer oil contaminants. [1] Insulating materials within electrical equipment liberate gases as they slowly break down over time. The composition and distribution of these dissolved gases are indicators of the effects of deterioration, such as pyrolysis or partial discharge , and ...

  3. Headspace gas chromatography for dissolved gas measurement

    en.wikipedia.org/wiki/Headspace_Gas...

    There is a need to analyze the dissolved gas content of aqueous solutions. Dissolved gases can directly interact with aquatic organisms [4] or can volatilize from solution (the latter described by Henry's law). These processes can result in exposure that, depending on the nature of the dissolved material, can have negative health effects.

  4. Degassing - Wikipedia

    en.wikipedia.org/wiki/Degassing

    New applications are in inkjet systems where gas in the ink forms bubbles that degrade print quality, a degassing unit is placed prior to the print head to remove gas and prevent the buildup of bubbles keeping good jetting and print quality. The above three methods are used to remove all dissolved gases. Below are methods for more selective ...

    Solid Waste Tree, Based on Resource Conservation and Recovery Act, United States Environmental Protection Agency. Solid waste means any garbage or refuse, sludge from a wastewater treatment plant, water supply treatment plant, or an air pollution control facility and other discarded material, including solid, liquid, semi-solid, or contained gaseous material resulting from industrial ...

  6. Deaerator - Wikipedia

    en.wikipedia.org/wiki/Deaerator

    Oxygen and Nitrogen are two non-condensable gases that are removed by deaeration. Henry's law describes the relationship of dissolved gases and partial pressures. Thermal deaeration relies on the principle that the solubility of a gas in water decreases as the water temperature increases and approaches its boiling point. In the deaerator, water ...

  7. Soil gas - Wikipedia

    en.wikipedia.org/wiki/Soil_gas

    Soil gases (soil atmosphere [1]) are the gases found in the air space between soil components. The spaces between the solid soil particles, if they do not contain water, are filled with air. The primary soil gases are nitrogen, carbon dioxide and oxygen. [2] Oxygen is critical because it allows for respiration of both plant roots and soil ...

  8. Total Petrochemicals USA - Wikipedia

    en.wikipedia.org/wiki/Total_Petrochemicals_USA

    The Total Petrochemicals USA headquarters is the Total Plaza in Downtown Houston, Texas. [3] In early 2005, Total Petrochemicals USA signed a lease to occupy space in the Louisiana Place. [4] In late 2005, Total Petrochemicals USA moved hundreds of employees into the building, whose name was changed from Louisiana Plaza to Total Plaza. [5]

  9. Soil aeration - Wikipedia

    en.wikipedia.org/wiki/Soil_aeration

    Soil aeration is the mechanism of improving the exchange of gases between the atmosphere and soil. Through soil microbial activity and plant root respiration, certain gases such as oxygen will be depleted in the soil, while others, such as carbon dioxide, will build up in the soil. [1] Lack of oxygen in the soil can impact plant growth.
