OBJECTIVES To examine the incidence of lymphohaematopoietic malignancy around industrial complexes that include major oil refineries in Great Britain after recent public and scientific concern of possible carcinogenic hazards of emissions from the petrochemical industry. METHODS Small area study of the incidence of lymphohaematopoietic malignancies, 1974-91, within 7.5 km of all 11 oil refine...
Support vector machine has been explored and many applications found within various research areas and application domains. Many support vector machine techniques have been specifically developed for certain application domains. This paper is an attempt to provide an overview on applications of support vector machines within the oil refineries to the professionals inside oil refineries, researc...
Problem statement: The reduction in ambient air pollution is a universal goal-particularly in urban areas, the lack of resources often necessitates identification and prioritization of sources of air pollutants. Efficient planning and effective management of environmental pollutants is thus important for optimum utilization of limited resources. Approach: This study examined seven years of data...
This study evaluated pollution levels in water and sediments of Península de Paraguaná and related these levels with benthic macrofauna along a coastal area where the largest Venezuelan oil refineries have operated over the past 60 years. For this, the concentration of heavy metals, of hydrocarbon compounds and the community structure of the macrobenthos were examined at 20 sites distributed al...
A typical crude oil supply chain consists of production oilfields, processing terminals, storage facilities and refineries, interconnected by means of pipelines. In processing terminals, different varieties of base crude-oils are received, processed and blended in order to produce commercial varieties which are exported and/or sent to refineries. In the last decade, very few contributions have ...
this paper describes the application of process integration principles to the design of oil refineries hydrogen network. in this regard, a design hierarchy as well as heuristics and required guidelines are proposed. the recommended rules compensate lack of procedure to the design and make the design process easier. the guiding principles of the design are based upon pinch technology and extendi...
We econometrically estimate the effect of transaction costs on the cost-effectiveness of the tradable permit market created during the US lead phasedown. We develop a methodology to identify transaction costs in the absence of price data. We find that refineries generally trade efficiently. We also, however, find evidence that transaction costs affect trading. We find evidence that refineries a...
1 Data 1.1 U.S. Refineries 1.1.1 Sources of data I match and compile three data sets on characteristics and imports of U.S. refineries collected by the U.S. Energy Information Administration (EIA): (i) capacity of distillation unit and upgrading units (parts 6-7 of form EIA-820: annual refinery report); (ii) imports of crude oil, (form EIA-814: monthly imports report) (iii) domestic purchases o...
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...
