But offshore the heavy cost of reinjection wells, and the apparent capacity of the marine environment to cope with low quantities...

... Abstract The use of natural gas as a fuel has been an attractive alternative in both economic and environmental perspectives. Natural gas pipelines show usually low internal corrosion rates. Hydrogen sulfide, carbon dioxide, water and other contaminants are removed to specified limits during...

... contaminants. Also, the SEM micrographs showed coke lay-down on the surface which cause affect catalyst efficiency. · EDS X-ray analysis showed the presence of carbon, iron, and sulfur in alumina inanity. The elemental sulfur segregated towards the interior bulk, while carbon was found mostly near the surface...

... Abstract. The specifications for contaminant concentrations in high purity ethylene and propylene have become increasingly stringent. The utilization of high activity polymerization catalysts by customers has been the principle driving force for the reduction in inhibitor concentration...

... and capable of being audited. Contaminated soils or components polluted in various ways must be examined before remediation in order to identify the best-suited specific cleaning or disposal method. Legal and ecological requirements, planning and analytical preparations as well as remediation measures...

... Abstract. Technologies for the clean-up of soil and groundwater contamination from petroleum industry activities have advanced considerably over the past decade. This has been the result of increasing regulatory pressures in many parts of the world, mounting liability exposure, changing public...

... high concentrations of contaminants, such as sulphur, nitrogen and metals. The viscosity factor represents an obstacle to transportation, but solutions to this are possible, either in the form of dilution or limited conversion to achieve pipelineability. Examination of the various factors influencing...

... Abstract. Groundwater supplies nearly 50% of the household water used in the United States, 26% in Canada and more than 70% in most of Europe. Groundwater usage is high in many other countries. The number of wells that have been found to be contaminated in North America and Europe has...

.... As expected the atmosphere in the region is basically clean, except for hydrocarbon levels in existing oil fields. Upper air meteorological conditions have also been measured. The influence of the Orinoco River on the transport of airborne contaminants is estimated based on a field programme with passive...

... of many individual specific problems. It is being pictured by many people and organizations to be a threat to public health, and as a result many problems arise regarding the detailed health effects of various contaminants, both singly and in combination with other contaminants. The economic effects...

La forte instabilité du TR O Moyen-Orient à la sévérité d'essai du JP 6 est expliquée par la présence de dérivés sulfurés et azotés. Le TR O saharien a une...

... Abstract. Commercial tonnage ethylene is so nearly chemically pure that its actual purity is frequently of less importance than the concentrations of specific impurities, so small that they are reckoned in parts per million. The sources of contaminants in high purity ethylene are discussed...

Because of the environmental conditions under which these aircraft operate, the contamination level of the fuel with water and solid material must be kept to a practicable minimum. This has been achieved by an improved understanding of the problem of fuel contamination...
