  • COST-EFFECTIVE SOLUTION FOR SO 2 EMISSIONS

    2019-1-17One of the most common methods used to reduce SO2 emissions is wet scrubbing, which uses a slurry or alkaline sorbent such as limestone or seawater to scrub the gases. In an FGD system, flue gas normally passes through a fly ash removal device, then an SO2 removal device.

  • Efficient and Cost Effective NOx and SO2 Removal from Flue

    1993-1-1The SNOX technology consists of five (5) key process areas which are particulate collection, NOx reduction, SO2 oxidation, sulfuric acid (H2SO4) condensation and acid management. Heat addition, transfer, and recovery also represent a significant part of the SNOX system.

  • A Novel Process Concept for the Capture of CO2 and SO2

    2014-1-1The process concept involves using a modified absorber column in which SO2 is absorbed in a bleed stream from the main absorbent flow in the bottom of the column. There is also a recycle flow allowing a small volume of the absorbent to be concentrated in SO2, which both increases the options for and reduces the cost of SO2 removal.

  • Sensors | Free Full-Text | Calibrations of Low-Cost Air

    Pollutant gases, such as CO, NO2, O3, and SO2 affect human health, and low-cost sensors are an important complement to regulatory-grade instruments in pollutant monitoring. Previous studies focused on one or several species, while comprehensive assessments of multiple sensors remain limited. We conducted a 12-month field evaluation of four Alphasense sensors in Beijing and used single linear

  • Modified Fe-Rich Palygorskite as an Efficient and Low-Cost

    2021-1-19In this article, the entire removal process was based on a cycle absorption system in which a primary-absorber was used to scrub SO2 by urea, then residual NO and SO2 could be oxidized by the vaporized H2O2/catalysts in the catalytic system, and finally, the soluble gaseous pollutants and the remaining gaseous oxidants were absorbed by ammonium sulfite that was produced from the primary
