Volatile Organic Compounds (VOCs) are generated in several industrial activities, namely in the petrochemical sector, and are present in liquid and gaseous effluents. These compounds are toxic, mutagenic and carcinogenic, thus requiring their elimination, at least to some extent. The VOCAdvanced project intended to make an important contribution to the removal of this type of pollutants and, consequently, to
minimize the negative environmental impacts and preserve the public health. With the VOCAdvanced project, it is studied the simultaneous decontamination of gaseous and liquid effluents containing VOCs by advanced oxidation processes, namely
homogenous and heterogeneous Fenton processes, using a bubbling column reactor. The processes was tested on gas and liquid streams using model VOC compounds usually generated in the petrochemical sector (e.g. toluene, acetaldehyde, xylene, and benzene) in order to remove them efficiently and at the lowest cost of treatment. |
