This paper introduces the oil and gas workplace context and describes work practices observed at a large Norwegian gas refinery. Ethnographic fieldwork was carried out over a ten day period, consisting of observational studies and informal interviews. They are a small, inter-disciplinary group who are highly mobile and work in a hazardous, critical environment where mistakes can pose risk to he...

UNLABELLED This case series details clinical observations in 7 survivors of accidental hydrogen sulphide inhalation toxicity at a petroleum refinery in Sri Lanka. One survivor developed status epilepticus and severe neurotoxicity whilst another survivor developed delayed respiratory failure; both patients required intensive care management. One victim manifested mild bronchospasms in the immedi...

This paper presents an integrated IT/IS investment evaluation framework based on IT/IS investment evaluation and business values and IS Success factors. The proposed framework involves different parts of organization or stakeholders whom are influenced by IT/IS investment decisions. It uses Delphi technique for selecting and grouping IT/IS investment criteria. Then, selected criteria are weight...

An Agilent Simulated Distillation (SIMDIS) system is described for quality control and monitoring of refinery processes. The system uses an Agilent 6890N gas chromatograph (GC) equipped with a programmable temperature vaporizer (PTV) inlet designed specifically for high temperature analysis. A simulated distillation software program that couples with the Agilent GC ChemStation provides an easy-...

Worldwide concerns about sulfur oxide (SOx) emissions from ships are motivating the replacement of marine residual oil (RO) with cleaner, lower-sulfur fuels, such as marine gas oil (MGO) and marine diesel oil (MDO). Vessel operators can use MGO and MDO directly or blended with RO to achieve environmental and economic objectives. Although expected to be much cleaner in terms of criteria pollutan...

This paper presents briefly some of the principal results of a mortality analysis of a cohort of workers employed for at least 1 year between 1950 and 1975 at eight oil refineries and approximately 750 distribution centers in the U.K., together with detailed results for kidney cancer and leukemia. Over 99% of the workers were successfully traced. Their mortality was compared with that of all ma...

PURPOSE Petroleum refinery workers' exposure to the carcinogens benzene and 1,3-butadiene has decreased during normal operations. However, certain occupational groups or events at the refineries still involve a risk of higher exposures. The aim of this study was to examine the personal exposure to benzene and 1,3-butadiene at refinery turnarounds and during work in the oil harbour. METHODS Pe...

OBJECTIVE Occupational exposure typical of an oil refinery may alter liver function among the workers. Thus, the objective of the study was to identify risk factors for liver enzyme abnormalities among oil refinery workers. METHODS The workers at an oil refinery in Northeastern Brazil underwent routine annual medical examination from 1982 to 1998. This case-control study investigated all the ...

Experiments were carried out to evaluate the batch adsorption of sulfur compounds from petroleum refinery wastewater on a chemically modified activated carbon (MAC). The modification technique enhances the removal capacity of carbon and therefore decreases cost-effective removal of sulfide from refinery wastewater. Different techniques have been used to characterize the modified activated carbo...
