Increasing global notices in environmental protection, green supply chain management (GSCM) has received much attention by researchers and managers more than the past. Commonly, firms have considered cost criteria to select their suppliers. Despite the fact that there are various papers considering the formal criteria in supplier selection, there is a few limited numbers considering the environ...

The prospection of bacteria that are resistant to polyaromatic hydrocarbons (PAH) activated sludge from a Petrochemical Wastewater Treatment Plant (WWTP) allows investigating potential biodegraders PAH. For this purpose, samples were cultured with benzo(a)pyrene and/or naphthalene as carbon sources. recovered isolates characterized by biochemical methods and identified based on the analysis seq...

growth of the petrochemical industry and its products has been followed growth in other sectors of production, use and trade of chemicals at national and regional levels. it is one of the basic industries which are feeder to other industry sectors as the engine of the economy and play a major role in developing countries. with no doubt mismanagement and improper use of chemicals lead to harmful...

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...

Industries produce millions of cubic meters of effluent every year and the wastewater produced may be released into the surrounding water bodies, treated on-site or at municipal treatment plants. The determination of organic matter in the wastewater generated is very important to avoid any negative effect on the aquatic ecosystem. The scope of the present work is to assess the physicochemical c...

The purpose of this paper is to manage the crisis caused by nano-technology in the petrochemical industry (Emam port). The collection of information contained in the petrochemical industry On the application of nanoparticles and the problems created by preparing questionnaires and to provide it on two levels: Managers and technical experts then analyze it done And also to study the biological e...

This paper presents a computer tool for tuning PID controllers. What makes this tool different to others available in the market is the ability to model the most important load disturbances. The MISO calculated model enables a better tuning of the PID loop, both for the servo and regulatory cases. This is of special interest in the Petrochemical Industry where most of the PID controllers have a...

The amount of wastewater depends on the technical level of process in each industry sector and will be gradually reduced with the improvement of industrial technologies. The increasing rates of industrial wastewater in developing countries are thought to be much higher than those in developed countries. This fact predicts that industrial wastewater pollution, as a mean environment pollution pro...
