  • Odor Control in Air Scrubbers

  • Air scrubber wastewater solution

    Air Scrubbers strip out contaminants from exhaust stacks typically by trickling a stream of salt solution through a bed of media to extract contaminants by putting them into solution. The salts found in these solutions are typically sulfates, chlorides, and carbonates. Air Scrubber wastewater tends to have high total dissolved solids (TDS) or salts. Air Scrubber Wastewater cannot be simply flushed down the drain. Many companies choose to avoid the headaches of labor-intensive wastewater treatment technologies such as chemical treatment or filtration and simply pay to haul the wastewater. This however, can become quite expensive.

  • Odor Scrubbers Applications with Hydrogen Peroxide

    Hydrogen Peroxide as a Replacement for Sodium Hypochlorite Hydrogen peroxide may be used in both mist scrubbers and packed tower scrubbers as a replacement for sodium hypochlorite (bleach). Like bleach, the process involves two concurrent mechanisms: 1) absorption of the odors (H2S) into the alkaline scrubbing solution; and 2) oxidation of the absorbed sulfide in solution. Step 1: H2S + NaOH → NaSH + H2O Step 2: 4H2O2 + H2S → H2SO4 + 4H2O Typical dose ratios are 5 parts H2O2 per part H2S or, when used in place of bleach, one gallon 50% H2O2 for every 10 gallons of 15% sodium hypochlorite (NaOCl). This generally translates into a break-even cost scenario. Sufficient caustic soda (NaOH) is added to maintain a pH of 10.0 - 10.5 in the scrubbing solution. There is also in practice a process which uses H2O2 in series with bleach to scrub composting odors. This process relies on a series of three packed tower scrubbers: the first is a pH neutral water wash (to remove ammonia and amine odors); the second uses a conventional caustic/bleach solution in which the bleach is purposely overdosed (to oxidize the complex organic sulfur odors); and the third uses a caustic/H2O2 solution (to remove the unreacted chlorine vapors carried over from the second stage). H2O2 + HOCl → HCl + H2O + O2 Typical dose ratios are 0.5 parts H2O2 per part hypochlorite (OCl-), with sufficient caustic soda (NaOH) added to maintain a pH of 8.5 in the scrubbing solution.

    Remote sensing of ship emissions

    New regulation forces ships to lower the emissions of SO2. Ships travelling in SECA areas has to either run on low sulphur fuel, or install SO2 scrubbers. To measure the SO2 emissions from a ship is not an easy task. OPSIS provides the Port Authorities with a unique measurement principle where the emissions from the ship is measured remotely. Light is passing the emissions and by analyzing the light, concentrations of SO2 can be measured.

  • Chlorine dioxide treatment for rendering

    Odor Control: Chlorine dioxide controls odors by destroying hydrogen sulfide through chemical oxidation.  Using an odor scrubber, chlorine dioxide solutions may be added directly to water containing the odorous compound for quick and cost-effective oxidations.

  • DeNox Systems

    Newland Entech Europe could reducing NOx emissions adding ozone to the flue gas before it enters the chimney. The ozone convert the NOx to N2O5, which it is high soluble in water and is easily removed from the flue gas by a scrubber.

    Applications and Air Pollutants Removed in the Biomass Industry

    Flue gas particulate and acid gases from biomass and bagasse boilers. Removal of ethanol, CO2 scrubbers and yeast cells from fermenters.  Removal of ash particulate, tars, acid gases and ammonia from steam reformers, gasifiers, pyrolosis units and cooling of syngas streams to acceptable limits to enable use as a fuel source for power generation or as a feedstock for chemical products. For tar removal, combination technologies can be used including oil based scrubbing solutions to reduce waste water generation. Ethanol and yeast cell removal from fermenter off-gases. Methanol from processing operations. Hydrogen sulfide removal on landfill, digester and producer gases with regenerable chemistries. Odor control for biomass storage facilities including carbon monoxide removal in wood chip storage areas.
