Petrochemical industries can potentially impact the environment due to their activities and products. This case study has considered adverse effects of petrochemical industries that are located inside the PETZONE with respect to the presence of polycyclic aromatic hydrocarbons and total petroleum hydrocarbon in wastewater effluents. The average concentrations of ∑PAHs group I and II were lower ...

This study applied a prediction-based portfolio optimization model to explore the results of portfolio predicament in the Tehran Stock Exchange. To this aim, first, the data mining approach was used to predict the petroleum products and chemical industry using clustering stock market data. Then, some effective factors, such as crude oil price, exchange rate, global interest rate, gold price, an...

Distillation has remained an important separation technology for the chemical process industries. In 1997 it was reported in the journal Chemical Engineering that about 95% of all worldwide separation processes use this technology. In the USA alone, some 40000 distillation columns represent a capital investment of about US $8 billion. They consume the energy equivalent of approximately 1 billio...

OBJECTIVE To evaluate possible adverse reproductive outcomes in an area adjacent to a petrochemical plant in southern Brazil. METHODS A review of 17,113 birth records of the main hospital of the municipality of Montenegro, southern Brazil, from 1983 to 1998 was carried out. Three groups of cases were selected: (1) newborns with major congenital malformations; (2) newborns with low birth weigh...

BACKGROUND Job stress and job satisfaction are important factors affecting workforce productivity. This study was carried out to investigate the job stress, job satisfaction, and workforce productivity levels, to examine the effects of job stress and job satisfaction on workforce productivity, and to identify factors associated with productivity decrement among employees of an Iranian petrochem...

The global bio-based chemical market is growing in size and importance. Bio-based solvents such as glycerol and 2-methyltetrahydrofuran are often discussed as important introductions to the conventional repertoire of solvents. However adoption of new innovations by industry is typically slow. Therefore it might be anticipated that neoteric solvent systems (e.g., ionic liquids) will remain niche...

The non-thermal plasma pyrolysis of fuel oil, under the action low-voltage electric discharges in liquid phase, has made it possible to develop a new process obtain valuable petrochemical products. In this study, main parameters, including pulse energy and time impact on process, are studied. components obtained gaseous products hydrogen (27.6–49.6 mol%), acetylene (33.6–49.1 ethylene (6.9–12.1...

In general, plant facilities are to large-scale production for oil refining, power generation, and gas . Various raw materials handled according the purpose of facility, in particular, there various Korea that process petrochemical products as materials. As most by these combustible, potential fire risk at such is very high. this study, was evaluated analyzing performance degradation structural...
