Complete treatment of sulfur dioxide (SO2) from flue gases in a two-stage process consisting of a biotrickling filter followed by biological post-treatment unit was investigated. The biotrickling filter could remove 100% of influent SO2 from simulated flue gas at an empty bed residence time of 6 s for a concentration range of 300-1000 ppm(v). All the absorbed SO2 was recovered in the biotrickli...

We evaluated the analytical performance of the i-STAT Portable Clinical Analyzer (PCA), a point-of-care testing system consisting of a hand-held analyzer and single-use cartridges that measure different panels of electrolytes, metabolites, blood gases, and hematocrit in 65-100 microl of blood. Our objective was to determine whether PCA measurements at the bedside of patients in the neonatal and...

BioDeNOx is an integrated physicochemical and biological process for the removal of nitrogen oxides (NOx) from flue gases. In this process, the flue gas is purged through a scrubber containing a solution of Fe(II)EDTA2-, which binds the NOx to form an Fe(II)EDTA.NO2- complex. Subsequently, this complex is reduced in the bioreactor to dinitrogen by microbial denitrification. Fe(II)EDTA2-, which ...

Elemental mercury in flue gases from coal combustion is difficult to control. However, oxidized mercury species are soluble in water and can be removed with a high degree of efficiency in wet flue gas desulphurization (WFGD) systems operating in coal combustion plants, provided that no re-emissions occur. In this article the mechanisms affecting the re-emission of oxidized mercury species in WF...

A stand has been developed for the study of thermal neutralization process oily waters. The design features stand, which allows simulating conditions in diesel flue, are described. tasks experiment formulated and characteristics measuring instruments given. first results an experimental waters presented. main series studies at data obtained on composition exhaust gases temperatures flue. These ...

Harmful pollutants (CO, NO, and unburnt hydrocarbons) coming out from the exhaust manifold of an engine must be converted into harmless gases by using catalytic converter. This field has seen vast research for increasing conversion efficiency different cheap metals. Nowadays, catalysts used in converter are noble metals, they also critical sense that not abundant on Earth. Platinum, palladium r...

Oxy-fuel combustion is a clean coal technology based on firing fuel in an enriched oxygen atmosphere to obtain a high CO2 concentration in the off-gases. This technology can be combined with the co-firing biomass and the use of blends of coal and biomass can compensate for the fact that the gas properties in the furnace in an oxycombustion process differ from the air-firing case (oxy-firing flu...

The air pollutions from combustion flue gas and industrial gases became worse and cause the environmental problem. It is difficult for the conventional methods such as selective catalytic reduction method and lime-gypsum method to treat exhaust gases energy efficiently and inexpensively. Its energy efficiency and its initial and running costs are still in negative situation for the backward nat...
