Contamination of the water bodies occurs from different sources including oil refineries. Oil refinery effluent contains different chemicals at different concentrations including ammonia, sulphides, phenol, hydrocarbons and heavy metals. Monitoring the impact of pollutants on aquatic life forms is challenging due to the differential sensitivities of organisms to a given pollutant, and the inabi...

We demonstrate that there is great variation in the size range and chemical composition of metalliferous particulate matter (PM) present within petrochemical complex chimney stacks. Cascade impactor PM samples from seven size ranges (17, 14, 5, 2.5, 1.3, 0.67, and 0.33 μm) were collected from inside stacks within the San Roque complex which includes the largest oil refinery in Spain. SEM analys...

The bioCRACK process is a promising technology for the production of second generation biofuels. During this process, biomass is pyrolized in vacuum gas oil and converted into gaseous, liquid and solid products. In cooperation with the Graz University of Technology, the liquid phase pyrolysis process was investigated by BDI - BioEnergy International AG at an industrial pilot plant, fully integr...

The main aim of this three-year follow-up study was to evaluate the long-term effects of a workplace health promotion intervention programme offered by the Neste Oyj corporation's occupational health service. Another aim was to study factors associated with changes in health promotion needs. These were assessed using information obtained by means of questionnaires and laboratory measurements. T...

Regarding the increased energy consumption of the processes at the operational units in the National Iranian Oil Company, the present study analyzed energy consumption at one of the gas refineries. In this refinery, which is the main supplier of Fajr Jam refinery for the national gas network, as well as an injection into the oil fields of the Iranian South oil company, the pressure of gas after...

The integrated refinery-planning (IRP), an instrumental problem in the petroleum industry, is made of several subsystems, each of them involving a large number of decisions. Despite the complexity of the overall planning problem, this work presents a mathematical model of the refinery operations characterized by complete horizontal integration of subsystems from crude oil purchase through to pr...

in this paper the issue of evaluating iranian oil refineries performance has been discussed. the research is based on math modelling by operational research techniques. to do so, of the proposed scenarios and different math programming models, a model is made by combining dea with goal programming techniques that compared with the old classical dea models which measures the efficiency and produ...

Unpublished AIChE shall not be responsible for statements or opinions contained in papers or printed in its publications ABSTRACT The refinery business involves tasks spanning across several departments and using large amounts of data. These processes include crude procurement, logistics scheduling, storage (tank) scheduling and crude scheduling. Integrated decisions based on the entire supply ...

The objectives of this work were to develop a means of sampling atmospheric dusts on the premises of an oil refinery for electron microscopic study to carry out preliminary morphological analyses and to compare these dusts with those collected at sites beyond the refinery limits. Carbon and collodion membranes were used as a support for collection of dust particles straight on transmission elec...
