  • Deareation: degasification of water using novel membrane technology

    Dissolved oxygen, nitrogen, and carbon dioxide are naturally present in water. Dissolved gases should be carefully monitored and controlled, as they can affect the products and processes in which the water is used. For example, dissolved oxygen can react with metais, forming an oxide Iayer on the surface of finished productsorpipingmaterial. AIso,asthe water ...

  • Degasification of boiler feed water with Liqui-Cel® membrane contactors

    Proper treatment of boiler feed water is an important part of operating and maintaining a boiler system. As steam is produced, dissolved solids become concentrated and form deposits inside the boiler. This leads to poor heat transfer ...

  • Boiler feed water degasification using membrane contactors - new methods for optimizing performance

    Abstract Membrane Contactors have been used to remove dissolved oxygen in boiler feed water systems for years. This report reviews various system designs and discusses how Membrane Contactors can ...

  • TB 38: Chemical-free membrane degassing in pharmaceutical plants

    Technology for the Removal of Dissolved GasesIn treating water for the production of pharmaceuticals, the concentration of gases dissolved in the water plays an important role. In many cases the CO2 content in the raw water has to be further reduced to obtain purified water with a conductivity of < 1.3 μS/cm (at a temperature of 25°C). membrane degasification system downstream of the RO ...

  • Coal sorption characteristics and coal surface tension

    Underground coal mining in the Bulli Seam of Sydney Basin, Australia encounters the problems of coal and gas outburst as the coal contains high concentration of CO 2 , where certain parts of the seam have been found to be especially hard-to-drain. In order to better understand these problems, the influence of temperature and moisture on sorption capacity of bituminous coal was investigated at ...

  • Treament of Hydrogen Sulfide (H2s)

    This gas is often found in groundwater that contains iron and manganese. It is easily identified by its "rotten egg" odor. In addition to causing serious taste and odor problems, sulfide also promotes the growth of sulfur bacteria. Hydrogen sulfide can cause corrosion problems with iron and concrete pipes and reservoirs. Sulfides are formed by the anaerobic reduction of sulfates and organic ...
