Clean Air & Clean Water Solutions for Your Plant. Wet Scrubbers. Gas flow rate is generally a constant parameter and may be monitored to ensure that the flow is within design range. Due to the acidity of HCl, it is somewhat more effectively scrubbed using an alkaline solution. Current designs can achieve more than 99% SO 2 removal, with system availability greater than 99.5%. A Wet Scrubber operates by introducing the dirty gas stream with a scrubbing liquid – typically water. For dust, fume & odour control, our low, medium and high energy venturi scrubbers are available in a number of designs with collection efficiencies greater than 99.9%. Plain recycled water may be used in HCl scrubbers; the wastewater stream will contain a weak hydrochloric acid solution, which may be of use to a plant. Our wet FGD systems, or wet scrubbers, have operated efficiently, economically and reliably since 1971. For wet scrubbers used to control acid gas emissions, monitoring scrubber liquid pH is an adequate surrogate for scrubber liquid outlet concentration. Wet scrubbers can serve two simultaneous functions: particulate collection and acid gas control. Packed bed scrubbers contact a liquid, typically water, with a gas to transfer a component of the gas into the liquid. For engineering, procurement, supply, and installation of wet scrubbers for industrial boiler systems in India, call at +91-9910490700. This atomized liquid (typically water) entrains particles and pollutant gases in order to effectively wash them out of the gas flow. For wet scrubbers used to control acid gas emissions, monitoring scrubber liquid pH is an adequate surrogate for scrubber liquid outlet concentration. Caustic solution (sodium hydroxide, NaOH) is the most common scrubbing liquid used for acid-gas control (e.g., HCl, SO 2, or both), though sodium carbonate (Na 2 CO 3) and calcium hydroxide (slaked lime, Ca[OH] 2) are also used. Exhaust gas flow rate affects the L/G ratio, which is a key design parameter for wet scrubbers. Scrubber Test Facilities at Karlsruhe R&D Center. Acid fume scrubbers remove or neutralize the harmful substances emitted from combustion or the storage of chemicals. The Anguil Acid Gas Scrubber neutralizes inorganic acids that often exist in a process exhaust stream or are created during the oxidation of air pollutants. The scrubber uses caustic liquids and injects them into the ventilation stack. As second stage, it is required to filter using dry scrubber, acts as polishing section, which removes the same pollutants even in low concentration. Utility Wet FGD Systems. Wet scrubber is an effective device to control gas and particle contamination from exhaust gas (US EPA, n.d.) (Byeon et al., 2012). Inside the tank are water spray nozzles. Acid gases from power plant and boiler combustion, such as sulfur dioxide and hydrogen sulfide, pose a major threat to human health and the environment. For wet scrubbers used to control acid gas emissions, monitoring scrubber liquid pH is an adequate surrogate for scrubber liquid outlet concentration. Our equipments used for a wide range of gases-fumes-dusts, such as Acid fumes (HCL, H2SO4, HNO3 etc) HCL gas-cl2-so2-Nox-NH3-H2S-FLU gases – Furnace gases & other gaseous effluent. A wet scrubber is an air pollution control device that uses liquid to remove contaminants/gases from the exhaust streams. REQUEST A QUOTE. It is one of the most critical indicators of the performance of the wettest scrubber designs. Scrubbers are one of the primary devices that control gaseous emissions, especially acid gases. Industrial Acid Gas Control Device Wet Scrubber. Envitech's acid gas scrubbers are custom-designed to provide removal efficiencies exceeding 99% for acid and toxic gases with a low pressure drop. The wet scrubbers help in meeting the effluent standards for industrial steam boiler systems. A Wet Scrubber operates by introducing the dirty gas stream with a scrubbing liquid – typically water. ft/min., is an important factor in the design of the scrubber vessel. APCINFRA has a specialised range of Wet Scrubbers for Acid Gas/Mist applications. High or low pressure, we deliver complete solutions including all rrocess control instrumentation and requirements. Wet air scrubbers constitute a versatile and cost-effective air pollution control technology that can eliminate more than 99 percent of airborne particulate matter. Wet scrubbers use a liquid to remove pollutants from a contaminated gas stream via absorption. The packed media provides mass transfer area to absorb acid gases such as SO 2, HCl, NH 3, and other gases. Wet scrubbers that remove gaseous pollutants are referred to as absorbers.
