Nowadays, energy supply is one of the most important issues due to limitation of oil, gas and coal sources. Because of rapid population, civilization and energy consumption growth, the improved technologies to make optimal use of the sources, solving related problems and finding new energy sources are important. More than 10 years ago, nanotechnology as one of the most important technologies has also been applied to progress in the oil and gas industry (upstream, midstream and downstream). The experience of these years has shown that application of nanotechnology in the oil industry improves the exploration of crude oil and natural gas (underground or deep water), drilling and bringing the crude oil or raw natural gas to the surface, as well as transportation, storage, processing and purifying methods. Nanoparticles with high specific surface area, pore volume and small size show unique physical and chemical properties, which could be applied in several applications. In this regard, many researchers have been focused on various nanoparticles for upstream industries and studied their potential in oil exploration, drilling, production and enhanced oil recovery (EOR). Also, in downstream and midstream which involve refining of crude oil, processing and purifying of raw natural gas, transportation and storage of crude or refined petroleum products, the nanomaterials have been used to improve the quality of oil and make it appropriate for the environment. Lowering sulfur gasoline, enhancing the octane number and coating the transportation system are among the goals that have been achieved successfully using nanotechnology. In this work, various types of nanoparticles such as metallic, metal oxide, hybrid nanoparticles, carbon nanomaterials, nano-composites and their applications in oil upstream industry are reviewed. Also, their usage in different types of oil upstream processes is discussed. 相似文献

为了实现油气回收和达标排放的目标,采用回收与处理相结合的研究思路,优选出了基于低温吸收和蓄热氧化的油气回收技术方案。对该技术方案进行了室内试验和现场试验,并对影响回收效果的两个主要因素进行了规律性研究。试验表明:当液气比、喷淋密度越大,吸收剂含吸收质初始浓度、煤油温度越低,以及油气中初始甲苯浓度越高时,吸收率越高;在进行油气吸收时吸收剂最好采用新鲜煤油;蓄热氧化处理过程中,洗涤气不可缺省;该技术方案油气吸收处理效果较好,室内和现场试验结果均达到了设计要求。此技术具有经济和高效的优点,对今后油气回收技术的发展具有一定的指导意义。 相似文献
