FTIR measurement of NH3, HCN, SO2, H2S and COS in pulverized lignite oxy-fuel flames
Nitrogen and sulphur compounds are investigated in the atmosphere of a high temperature oxy-fuel flame, using Fourier Transform Infrared Spectroscopy (FTIR). For this application, evaluation routines have been developed to investigate the concentrations of NH3, HCN, SO2, H2S and COS by analyzing the absorption intensity of characteristic fingerprints within the strong overlapping of the CO2 ric...
متن کاملBiotreatment of H2S- and NH3-containing waste gases by co-immobilized cells biofilter.
Gas mixture of H2S and NH3 in this study has been the focus in the research area concerning gases generated from the animal husbandry and the anaerobic wastewater lagoons used for their treatment. A specific microflora (mixture of Thiobacillus thioparus CH11 for H2S and Nitrosomonas europaea for NH3) was immobilized with Ca-alginate and packed inside a glass column to decompose H2S and NH3. The...
متن کاملTwo-stage biofilter for effective NH3 removal from waste gases containing high concentrations of H2S.
A high H2S concentration inhibits nitrification when H2S and NH3 are simultaneously treated in a single biofilter. To improve NH3 removal from waste gases containing concentrated H2S, a two-stage biofilter was designed to solve the problem. In this study, the first biofilter, inoculated with Thiobacillus thioparus, was intended mainly to remove H2S and to reduce the effect of H2S concentration ...
متن کاملProjections of SO2, NOx and carbonaceous aerosols emissions in Asia
Estimates of Asian emissions of air pollutants and carbonaceous aerosols and their mid-term projections have been changing significantly in the last years. The remote sensing community has shown that increase in NOx in Central East Asia is much stronger than any of the emission inventories or projections indicated so far. A number of studies reviewing older estimates appeared. Here, we review t...
متن کاملInteractions of SO2 and H2S with amorphous carbon films
There is significant interest in development of efficient catalyst-sorbents for the capture and conversion of sulfur-compounds such as H2S and SO2. In this work, ultra-high vacuum (UHV) techniques have been used to carefully prepare and thoroughly characterize amorphous carbon (a-C) thin films as models of activated carbon sorbents. Films with modified surface chemistries were prepared by oxida...
