More than 200 kg real waste electrical and electronic equipment (WEEE) shredder residues from a German dismantling plant were treated at 650 °C in demonstration scale thermochemical conversion plant. The focus within this work was the generation, purification, analysis of pyrolysis oil. Subsequent filtration fractional distillation combined to yield basic chemicals high purity. By means distill...

The effects of groundwater table fluctuation (GTF) on the remediation a petrochemically polluted riverside using soil vapor extraction (SVE) were investigated. migration and transformation benzene, toluene, ethylbenzene, o-xylene (BTEX) in cases natural attenuation, SVE without GTF, with GTF simulated TMVOC model. results showed that optimized well pressure influencing radius target site 0.90 a...

abstract background: biogas is obtained by anaerobic decomposition of organic wastes buried materials used to produce electricity, heat and biofuels. biogas is at the second place for power generation after hydropower and in 2000 about 6% of the world power generation was allocated to biogas. biogas is composed of 40–45 vol% co2, 55–65 vol% ch4, and about 1% non-methanevocs, and non-methane vol...

background: several effects of volatile organic compounds (vocs) have been recognized such as toxic and carcinogenic human health effects. to evaluate cancer risk of benzenes air samples were taken, at an automobile manufacturing painters in tehran following inhalation exposure. methods: to perform this study, cross-sectional was done in 2016. sampling was carried out by active pump sampler usi...

Deep-UV absorption spectrometry for detection of toxic airborne gases, instance, Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX) has drawn considerable attention owing to its high sensitivity reliability. However, the development a deep-UV absorbance detector having good sensitivity, portability, low-volume gas cell with applicability micro Gas Chromatography (μGC) is challenging. Herein we ...

This study aimed to determine the impact of artisanal refinery operations on physicochemical and microbiological properties soil water in Igia-Ama, Tombia Kingdom, Rivers State, Nigeria. Physicochemical parameters along with concentrations heavy metals, polyaromatic hydrocarbons (PAHs), total petroleum hydrocarbon (TPH), benzene, toluene, ethylbenzene xylene (BTEX), polychlorinated biphenyls (P...
