对石油库装卸油过程中静电的产生、静电的分布以及产生静电危害的环节进行了研究,认为装卸油过程中的静电是由油品的流动、喷射、冲击和沉降等四种形式产生的,过滤器是静电的主要生产源,发生静电危害的主要环节是油罐车和储油罐。在上述研究的基础上,以引起静电危害的四个条件为依据,提出了装卸油过程中防静电危害的一整套措施:①控制流速,以降低摩擦速度;②管路中应昼少安装过滤器;③管路上应尽量减少闸阀和弯头,以减少油 相似文献

随着汽车工业的快速发展,汽车的保有量在逐年增加,它在给人们的生活带来方便的同时,但排放的污染物也越来越多,给人们的生产、生活以及环境造成了日益严重的危害.随着石油资源的逐步减少和以汽油、柴油为燃料的汽车对生态环境所造成的污染,除了对以汽油、柴油为燃料的汽车在技术上进行改造和采取比较严格的控制标准以外,采用清洁燃料去替代汽油、柴油,从而减轻汽车排放的污染物对人和环境所造成的不良影响,是今后汽车发展必须进行认真探讨和研究的重要课题. 相似文献

The tests conducted with the three vehicles at different emission control levels suggest that, in the area of fuel economy and emissions, potential benefits with methanol blends are related to carburetion and are only significant in the case of the rich-operating cars built before emission control standards were imposed. Theoretical considerations related to methanol's leaning effect on carburetion support this conclusion. Potential advantages for methanol in these areas are therefore continuously diminishing as the older cars leave the roads. At present, these older cars use only about one-fourth of the totalc motor gasoline consumed and, before methanol could be used on a large scale, this fraction would be much smaller. The use of methanol in gasoline would almost certainly create severe product quality problems. Water contamination could lead to phase separation in the distribution system and possibly in the car tank as well, and this would require additional investment in fuel handling and blending equipment. Excess fuel volatility in hot weather may also have adverse effects on car performance if the methanol blends include typical concentrations of butanes and pentanes. Removal of these light hydrocarbon components would detract from methanol's role as a gasoline extender and if current fuel volatility specifications were maintained, its use could lead to a net loss in the total available energy for use in motor fuels. Car performance problems associated with excessively lean operation would also be expected in the case of a significant proportion of late-model cars which are adjusted to operate on lean fuel-air mixtures. If methanol does become available in large quantities, these factors suggest that it would be more practical to use it for purposes other than those related to the extending of motor gasoline, such as for gas turbines used for electric power generation. In this case, the "pure" methanol would act as a cleanburning fuel, having none of the potentially severe product quality problems associated with its use in motor gasoline, while the fuel oil or natural gas cLirrently burned in these tuLrbines CotLild be diverted to other ulses. 相似文献

The ingestion by seabirds of fossil fuel hydrocarbons and other pollutants has been of great interest. This paper reports that storm-petrels ingest petroleum at sea and that residues can be detected in their stomach oil. The incidence of gut samples containing fossil fuel hydrocarbons (dirty samples) increased significantly after oil spills, and significantly more birds regurgitated dirty samples after large nearby spills than small distant ones. This appears to be one of the first reported instances where individuals of a natural population of marine birds have been shown to ingest sublethal doses of oil from sources of low-level, long-term pollution or from oil spills. Because of certain natural traits, Procellariiformes could serve as monitors of pollutants in the marine environment. 相似文献
