正石油分子工程是突破以往对石油的粗犷认知与管理,从分子水平实现石油炼制过程的精细化。人类对石油的认识正在走向深入。早期,根据石油蒸馏残渣的性状,把石油分为石蜡基、沥青基(环烷基)、混合基(中间基)三类。随着对石油性质及组成的进一步认识,又提出了许多以性质、组成或产品质量为基础的分类法,如以特性因数(由石油的平均沸点  相似文献

针对MTHS分子矩阵的分子表征优化模型进行改进,提出了一种通过工业常用的物性参数估计汽油分子组成的方法。使用蒸馏曲线和密度等工业常用参数,由相关性公式计算得到其他整体性质,以各项性质实测值与预测值的残差平方和为目标函数建立优化模型,并利用遗传算法对模型进行优化求解,得到预测的汽油馏分分子组成。由Aspen Plus模拟软件计算9组已知组成的汽油试样的整体性质,并应用改进模型对9组汽油试样进行分子组成预测。实验结果表明,改进模型较原始模型的精度更高,可用来近似估计汽油馏分的分子组成。  相似文献

过套管电阻率测井是在钢套管内测量地层电阻率进而进行含水饱和度评价和油藏监测的一种新的测井方法.由于测量结果为点测数据,需要在数据预处理时由多个单点数据重构整条曲线,而传统的插值方法,分辨薄层的能力差,因此文章提出了一种基于压缩感知的数据重构方法,使用点测深度和欲重构数据的深度匹配关系,建立观测矩阵,基于傅立叶变换的稀疏分解矩阵,采用OMP算法解决稀疏分解系数L1范数最小化问题,取得了良好的重构结果.  相似文献

通过不同碳链长度的正构烷烃与石油磺酸盐-非离子表面活性剂和石油磺酸盐-十二烷基苯磺酸体系之间动态界面张力的研究,发现混合表面活性剂在降低界面张力能力方面的协同效应不仅与表面活性剂分子之间的相互作用有关,而且与油相性质密切相关。从表面活性剂分子亲水能力和亲油能力方面为协同效应提出了一个新的解释。  相似文献

The long-term strategy of the development of the oil refining and petrochemical industry of the Russian Federation has been discussed. Such measures as the elaboration of the master plan of the development of oil refining and petroleum chemistry until 2020, providing Russian banks with state guarantees on loans to finance the construction of new and upgrading existing refineries, and the prompt enactment of the technological requirements for petroleum products have been singled out as the most important ones. The current status of oil refining in Russia has been analyzed. It has been shown that an extremely low proportion of secondary processes is the cause for the lagging behind of the domestic petroleum refining industry as compared to industrialized countries. The main challenges facing domestic oil refining have been specified. Considerable attention has been paid to the issues of improving the quality of petroleum products and bringing it up to world standards. The most important projects for the upgrading of existing and the construction of new refineries, as well as projects to build new oil refineries, have been examined.  相似文献

The oil refining industry in China supports the needs of national economic development and has gone through industrial upgrading at all stages, as represented by the upgrades in the quality of refined oil products.Currently, it has acquired strong technical and engineering strength and delivered good results in scale, information technology and environmental friendliness. However, compared with the world's leading oil refining powers, the oil refining industry in China still lags behind in terms of overall competitiveness. There is an urgent need to enhance its competitiveness and adjust its product structure, plant structure and capacity structure to both launch a new round of industrial upgrading and coordinate with the associated industries. Great potential exists for China to cooperate with the countries along the Belt and Road initiative in various fields such as petroleum resources, product markets and technical equipment. Together, multi-dimensional cooperation bonded by resources, markets, technologies and capital/funds can be carried out, and cooperation between the upstream and downstream industries throughout the industry chain can be facilitated. There is much to expect from the prospects for cooperative development.  相似文献

China has formed a complete and packaged system of domestic petroleum refining industry. Till 2020 the demand for petroleum products in China will record a sharp growth. However, China is currently confronted with a shortage of oil resources, unsatisfactory quality of petroleum products, a widening gap between demand and supply of steam cracking feedstocks, and a stern situation in environmental protection. In this context the petroleum refiners of China, while taking into account the actual conditions, should seek for the way of deep processing to produce transportation fuels and chemical feedstocks that can hardly be replaced by other energy forms, continue to bring into full play FCC process as core process for making finished oil products, speed up the development of hydrocracking to achieve integration between refining and chemical production, adopt measures that can combine feedstock pre-treatment, novel FCC technologies and after-treatment of products to improve the quality of finished products, as well as realize the recycling of wastewater and control over air pollution caused by SOx to accelerate the development of petroleum processing industry in China.  相似文献

石油经济学是一门年轻的学科。本文通过对石油经济学研究现状的考察,从系统和综合的观点出发,对石油经济学的性质及其研究对象的科学涵义进行了论证。石油经济学是经济学基本理论在石油产业系统中具体应用的专门学问,其研究对象是国民经济中围绕石油的勘探、开发、储运、炼制、化学深加工以及石油消费所形成的一系列经济运动的总和。它既不同于石油工业经济学,也有别于能源经济学。石油经济学的基本内容包括:石油经济在国民经济中的作用和地位;石油经济的系统结构和综合布局;石油经济的内在运行机制及其组织与管理;石油经济中的资金运动与石油经济效益;原油及油品的成本、价格和税收;石油经济中的对外开放与石油经济的发展战略,以及世界石油经济与国际政冶的关系等十一个方面。本文通过以上论述提出发展和完善我国石油经济学理论体系的任务。  相似文献

Information on the composition and properties of petroleum feedstock is important for selecting the optimum refining scheme due to the constant stiffening of quality requirements for petroleum products. This ensures the rational use of power resources at refineries, oil companies, and the state as a whole.
