Integrated system for the treatment of oxides of nitrogen from flue gases.

A novel and effective system was developed for the complete treatment of NOx from flue gases. The system consisted of photocatalytic or ozone oxidation of NOx, followed by scrubbing and biological denitrification. Maximum photocatalytic oxidation of NOx was achieved while using powdered TiO2 at a catalytic loading rate of 10 g/h, relative humidity of 50%, and a space time of 10 s. The used cata...

An improved HPLC method for determination of colocynthin in colocynth

Background and objectives: Colocynthin is the major active secondary metabolite of colocynth, Citrullus colocynthis (L.) Schrad, which has been used in traditional and ethno medicine of many countries.  It could be considered as an active marker for quality control of colocynth and its herbal products. Analysis and standardization of colocynth and its herbal preparations are a critical...

Experimental Studies of CO2 Capturing from the Flue Gases

CO2 emissions from combustion flue gases have turned into a major factor in global warming. Post-combustion carbon capture (PCC) from industrial utility flue gases by reactive absorption can substantially reduce the emissions of the greenhouse gas CO2. To test a new solvent (AIT600) for this purpose, a small pilot plant was used. This paper presents the results of studies ...

Biological System for the Treatment of Nitrogen Oxides from Flue Gas

Oxides of nitrogen (NOx) is responsible for troposphere ozone and urban smog through photochemical reactions. The rapid economic growth and unlimited consumption of fossil fuels have resulted in large emissions of NOx. Due to the adverse environmental effects, environmental regulatory agencies are compelled to enforce stringent NOx emission standards. Recently promulgated Clean Air Interstate R...
