  • Steel Degassing With Aerzen Vacuum Blowers

    Applications in the steel industry During the production of high-quality steels Aerzen Vacuum Blowers are used for further processing of the melt, the so-called steel degassing. Vacuum Blowers are used after the so-called “refresh“ of the steel, where oxygen is blasted into the pig iron. During this metallurgic further processing of the melt, the so-called secondary ...

  • Degassing Refrigerators - Drill-head and Piercing-plier

    1. For what purpose do we have to degas a refrigerator? A refrigerator has to be disposed as hazardous waste. The refrigerants inside a hazardous refrigerator are harmful for the environment (ozone depleting and greenhouse effect). Most common refrigerants are; R12, R134a and R600a. The uncommon is the removal of NH3. Refrigerants are developed to dissolve very easily into ...

  • 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 ...

  • TB 59: Optimized deaeration system for Paulaner Brewery

    The Centec DGS System is a modular, water deaeration process that uses hydrophobic Hollow Fiber Membrane to remove dissolved gasses from liquids in the beverage industry. This technical brief covers the unit’s design, operation and resulting reduction of energy consumption costs. Gas transfer starts with the basic principle that the concentration of dissolved gasses in water is proportional to ...

  • Boiler feedwater deaerators

    The thermophysical deaerator is by far the most applied technology when oxygen and carbon dioxide in Boiler Feed Water must be reduced to negligible concentrations Bono ARTES has inherited the experience in the design of Deaerators that started up within the BONO Group in 1959. The Boiler Feed Water, if in equilibrium with the atmosphere, may contain significant levels of corrosive gases, mainly ...

  • TB 72: Chinese chemical plant optimizes water treatment by replacing double pass ro with a single pass ro and liqui-cel® contactor system

    Electrodeionization (EDI) is widely used in many industrial water treatment systems throughout the world. In order to maximize the operating stability and life expectancy of an EDI system they were often designed with double pass RO using caustic injection pretreatment. However, in response to recent efforts to lower the capital expenditure and operating costs of double pass RO water treatment ...

  • Food and Beverage - L&S Sweetener Company - case study

    Application L&S Sweeteners of Honey Brook, Pennsylvania, had wastewater disposal issues resulting from the cleaning process for trucks bearing various liquid sweeteners, which must be cleaned between shipments per USDA requirements. Wastewater Description The company’s wastewater was derived from the cleaning of liquid sugar products from tank ...


  • Separation principle of decanting centrifuge

    KOSUN DC series decanting centrifuge is used in separating suspension of solids phase with particle diameter(d≥2μm) for drilling mud and fluids handling. Ruggedly built for oilfield and industrial services, it is especially effective in environmentally sensitive areas. It delivers high fluid-recovery rates and ...


  • Effect of high solids concentration on hydrodynamics and mass transfer of a three-phase airlift reactor for marine sediment bioremediation

    The more restrictive limits for environmental pollution control imposed nowadays require the development of new biological technologies. Multiphase reactors including slurry reactors have become reactors of choice for chemical and biochemical applications. In the present work, three-phase airlift reactors are proposed as an alternative to mechanically stirred systems and slurry bubble columns for ...

  • Clean your test sieves to maintain accurate results

    A standard process in analytical laboratories is sieve analysis, the practice of accessing the particle size distribution of a granular material. The trouble is, sieves prove quite the challenge to clean thoroughly enough to get all the contaminants out of the mesh. Every last grain stuck in the sieve must be removed to gain accurate analysis. A solution has been found in the use ...

  • Give it a Whirl

    The oil and gas industry uses so-called cyclones to separate mixtures of solids, fluids, or gases by centrifugal forces. The company ASCOM that was acquired by Sulzer in 2014 has developed a new generation of compact cyclonic separators with a large operating range. This equipment can be used inline inside pipe segments, replacing conventional technology that requires several large vessels. ...

  • Recovery of methane from anaerobic process effluent using poly-di-methyl-siloxane membrane contactors

    This paper demonstrates the potential for recovering dissolved methane from low temperature anaerobic processes treating domestic wastewater. In the absence of methane recovery, ca. 45% of the produced methane is released as a fugitive emission which results in a net carbon footprint of −0.47 kg CO2e m−3. A poly-di-methyl-siloxane (PDMS) membrane contactor was applied to support sweep gas ...
