Thermally activated persulfate oxidation of NAPL chlorinated organic compounds: effect of soil composition on oxidant demand in different soil-persulfate systems
This study investigates the interaction of persulfate with soil components and chlorinated volatile organic compounds (CVOCs), using thermally activated persulfate oxidation in three soil types: high sand content; high clay content; and paddy field soil. The effect of soil composition on the available oxidant demand and CVOC removal rate was evaluated. Results suggest that the treatment ...

The problem with halogenated compounds emissions and its solution
Halogenated compounds contain in their molecular structure an halogen, that is, molecules of chlorine, bromine, fluorine, iodine, etc. Several organic compounds may contain halogens, and thy are dangerous for people and the environment. Some examples of halogenated compounds are methyl chloride (CH3Cl), methyl bromide (CH3Br) and methyl iodide (CH3I). Some of the problems caused by halogenated ...

Chemical Mfg. Plant Avoids Long Term Shut Down with Thermal Oxidizer
Recently, Catalytic Products International (CPI) worked with a customer who determined during a routine plant inspection that they had unexpected emissions from their process. This can happen as regulations change and as plants continue to improve operations or even change products or processes. In this case, the customer voluntarily shut down their process immediately until a solution could be ...

Fluidized bed scrubber: operating principle and applications
There is an opinion that modern fluidized bed scrubbers replace venturi/packed scrubber systems because they allow solving fouling problems, increasing capacity, adding particulate removal capability, and controlling environmental conditions. The thing is that fluidized bed scrubber systems demonstrate efficient removal of PM10 and PM2.5 particulate resulting in high-efficiency gas absorption. ...
