  • Carbon Monoxide, Carbon Dioxide and Indoor Air Quality

    Chances are that unless you are hot or cold – or if you smell something funny – you probably never think about indoor air quality. However, scientists know that gases in the air that you cannot see or smell can still affect your health. Carbon Monoxide The most dangerous gas most of us will ever face is carbon monoxide (CO). Not normally occurring in nature, this ...

  • Carbon dioxide gas case study

    Application Moisture] is measured in carbon dioxide gas pipelines and processing plants. Problem The presence of moisture in carbon dioxide gas promotes corrosion. Perhaps more significant is the fact that moisture will readily form ice when pressure is reduced. The ice can readily freeze up pressure regulators, valves, and orifice plates causing a loss of flow and even ice ...

  • Removal of carbon dioxide from the atmosphere to reduce global warming: a modelling study

    We propose non–linear models to study the feasibility of removing CO2 from the atmosphere by introducing some external species such as liquid droplets and particulate matters in the atmosphere, which may react with this gas and get it removed by gravity. Further, this gas can also be removed by photosynthesis process upon using plantation of leafy trees around the sources of ...

  • Nutrient removal in wastewater treatment high rate algal ponds with carbon dioxide addition

    The influence of CO2 addition to high rate algal ponds (HRAPs) on nitrogen removal was investigated using two pilot-scale HRAPs operated with different hydraulic retention times (HRT: 4 and 8 days), and was compared to the nitrogen removal by the 8-day HRT pond before CO2 addition was installed. Nitrogen balances were calculated by partitioning total nitrogen into organic and inorganic nitrogen ...

  • Feasibility of using ionic liquids for carbon dioxide capture

    Ionic liquids (ILs) are organic salts that are liquids in their pure state at ambient conditions. They are frequently referred to as "environmentally benign" due to their immeasurably low vapour pressure. In addition to their more widely studied capabilities as solvents for reactions, several ionic liquids also show potential in other environmentally conscious applications, such as in the capture ...

  • How to use Electrocoagulation for Effective removal of Phosphorus in Wastewater

    In this article, we will be discussing phosphorus, the effects of elevated phosphorus levels on an ecosystem, and how innovative electrocoagulation technology can be sustainably used for effective removal of phosphorus in wastewater & water sources. What is Phosphorus? Phosphorus is one of the most common nutrients on the planet. It is formed naturally in nature, and ...

  • CO2 Monitor For Breweries: Carbon Dioxide Safety and How to Stay Safe

    Carbon dioxide is a necessary byproduct of the brewing process, yet too much CO2 can be dangerous to employee health. In Germany, two workers died at the same brewery in 2012 due to hazardous levels of CO2 present in beer mixing and pressure tanks. Learn more about how CO2 levels can get out of control during the beer brewing process and ways to protect your staff from this deadly gas.  ...

  • Capture of carbon dioxide from flue gas using solid regenerable sorbents

    Carbon dioxide emissions from the combustion of fossil fuels are a significant factor in global climate change. Large stationary sources such as coal-fired electric generating plants are likely to be the most cost-effective targets for carbon dioxide capture. At present, liquid amine-based scrubbing systems are the only processes available for this application. Processes based on regenerable ...

  • CO2 removal can lower costs of climate protection

    “Carbon dioxide removal from the atmosphere allows to separate emissions control from the time and location of the actual emissions. This flexibility can be important for climate protection,” says lead-author Elmar Kriegler. “You don’t have to prevent emissions in every factory or truck, but could for instance plant grasses that suck CO2out of the air to grow – and ...

  • Removing Struvite from wastewater systems

    Named after Henrich Christian Gottfried Von Struve, who discovered the magnesium ammonium phosphate crystals in medieval sewer systems in Hamburg in 1845, struvite is a major problem for waste water treatment plants. The hard, crystalline deposit forms scale on lines and belts, in centrifuges and pumps.  It also clogs system pipes and other equipment including anaerobic ...

  • Forests for Carbon: Exploring forest carbon offsets in the U.S. South

    Southern U.S. forests remove carbon dioxide from the atmosphere and store it in the form of carbon in leaves, roots, branches, trunks, soil, and woody debris and other plant litter through a process known as “carbon sequestration.” Through this process, southern forests and other woodlands play a role in regulating Earth’s climate and moderating the effects of global climate ...

  • Carbon capture could be costly and risky

    There’s bad news for those who think that carbon dioxide can be removed from the atmosphere and stored deep in the Earth’s rocks. Even if carbon capture is possible, sequestration in the rocks is fraught because the gas can find multiple ways to escape, according to a report by a team from Penn State University, US, in the International Journal of Greenhouse Gas Control. Back in the ...

  • Microcystin-LR removal from drinking water supplies by chemical oxidation and activated carbon adsorption

    Microcystin-LR (MC-L) is among the most toxic and frequent cyanotoxins found in surface water and a provisional value of 0.001 mg/L is indicated by World Health Organization guidelines for water for human consumption. Among the conventional processes used for surface water treatment, the most effective in microcystin removal are chemical oxidation and adsorption. This study investigated two ...

  • Ethylene removal in domestic refrigerators

    Ethylene is a plant hormone produced naturally by fruit and other plant tissues. It is known as the ripening hormone because it regulates the series of processes associated with the ripening and senescence of fruit. Ethylene removal from the environment, both in storage chambers and transport containers, where it is stored in the form of gas, is a widespread practice designed to provide a ...

  • Electronic Water Treatment - An alternative solution to removing beerstone and limescale

    Beer contains 90% water and is the most important ingredient in determining its flavor.  Water contains calcium and is the most important mineral to the brewing process.  The levels of calcium in local water have determined the type of beer produced.  The different types of beer whether a light lager or a porter are for the most part due to the water profiles of the areas that made ...

  • A comparative study on removal of basic violet 10 by adsorption and photocatalytic degradation using low cost activated carbon

  • Power Plant in Thailand Uses Liqui-Cel® Membrane Contactors to Remove CO2 From Water

    A major power plant in Thailand is using Liqui-Cel® Membrane Contactors to remove carbon dioxide from a DI water system. The system is an expansion project and will be used to feed a high pressure boiler. Liqui-Cel Contactors are being used to lower the CO2 inlet into an Ionpure EDI system. Carbon dioxide adds an ionic load to the EDI system, which canreduce the performance of the system. ...
