background : in this study, the inhibitory effect of ethylene dichloride (edc) on biodegradation was investigated using the specific methanogenic activity (sma) test of anaerobic biomass. methods: in the present study, 40 sma tests were performed using 120-ml vials in batch mode. substrate, biomass, and biogas occupied 66%, 17%, and 17% (v/v) of the volume of each vial, respectively. the durati...

The supported transition metal oxides, chlorides, carbides, and so forth (MXn), represent an important type of catalyst for redox processes. MXn–support interaction, analogous to metal-support plays a critical role in reactions. Herein, we illustrated the nature monolayer CuCl2–γ-Al2O3 its catalytic consequence induced by support facets ethylene oxychlorination. Kinetic theoretical studies, com...

The EU Emissions Trading System (EU ETS), which is a cornerstone of the EU’s policy to combat climate change, has been criticised by its effects on the competitiveness of intensive energy demanding industries, and in particular, of the chlor-alkali sector. The main chlorine application in Europe is the production of polyvinyl chloride (PVC) from ethylene dichloride (EDC) as intermediate. Since ...

In general, ethylene/1,3-butadiene copolymerizations provides copolymers possessing both pendant vinyls and vinylenes as olefinic moieties. We, at MCI, studied the substituent effects of C2-symmetric zirconocene complexes, rac-[Me2Si(Indenyl’)2]ZrCl2 (Indenyl’ = generic substituted indenyl), after activation on the ratio of the pendant vinyls and vinylenes of the resultant copolymers. Complexes...

Abstract The high-purity ethylene dichloride (EDC) head tower is an important pressure vessel in the vinyl chloride production process. During manufacturing process, bending test of 2 product specimens broke. In this paper, failure analysis fracture welding plate was carried out, and a systematic analysis, including chemical composition, mechanical properties, microstructure, out. causes welded...

For each of the 148 toxicants, EPA established a "benchmark" level that the agency considers safe. Eight of the 148 industrial poisons exceed EPA's benchmark safety levels all of the time in all 60,803 census tracts. All eight are carcinogens, that is, they are known to cause cancer: bis(2-ethylhexyl) phthalate; benzene; carbon tetrachloride; chloroform; ethylene dibromide; ethylene dichloride;...

During the production of ethylene dichloride, entrainment catalyst particles out bed is considered a problematic issue that affects conversion hydrogen dichloride and causes repeated unit shut down. In this study effect various operating conditions was measured; fluidizing gas flowrate, parameters, reaction conditions, static design parameters such as internal orifice diameter distributer. A si...
