Crude oil is a viscous dark liquid resource composed by mix of hydrocarbons which, after refining, used for the elaboration distinct products. A major concern that many petroleum components are highly toxic due to their teratogenic, hemotoxic, and carcinogenic effects, becoming an environmental on global scale, which must be solved through innovative, efficient, sustainable techniques. One most...

Software Interoperability for Petroleum Applications — In this introduction to the thematic dossier on software interoperability, we emphasise the key role of software for the petroleum industry, and we give market and technical motivations for interoperability. This is followed by a brief overview of the technologies used in the search for interoperability and by a summary of the five technica...

this study sougth to the effect of occ pulp fractionation on produced paper strength properties improvement. using a pressure screen, occ pulp was devided to tow distinct fractions of accept ratio (short fibers) and reject ratio (long fibers) in accordance with optimum condition of fractionation based on the previous studies. in the next stage, long fiber stream was refined and recombined with ...

Phenol and Phenolic compounds has several sources including industrial wastes, coal , wood distillation, road tars, petroleum refining, chemical plastics manufacture, domestic sewage discharges, natural such as plant material decay leaching from oil deposits enter water system affect the fish other aquatic organisms So static renewal bioassays were done to study influence of pH on lethal toxici...

Petroleum refineries around the world have generated the solid wastes during the refining process and stocking of crude oil. Oily sludge leads to critical effects in the environment. The ecology of hydrocarbon degradation by microbial populations in the natural environment is reviewed, emphasizing the physical, chemical, and biological factors that contribute to the biodegradation of petroleum ...

An oil spill is the accidental or intentional discharge of petroleum products into the environment due to human activities. Although oil spills are actually just a little percent of the total world oil pollution problem, they represent the most visible form of it. The impact on the ecosystems can be severe as well as the impact on economic activities. Oil spill cleanup is a very difficult and e...

Five experimental petroleum extracts were produced from luboil distillates derived from Middle East paraffinic crude by solvent extraction and severe hydrotreatment. The polycyclic aromatic content (PCA) of the extracts was determined by dimethyl sulphoxide extraction and ranged from 3.7-9.2% w/w. The five extracts were evaluated for their potential to induce cutaneous and systemic neoplasia in...
