南充炼油厂原油储罐说明书.doc

摘要 随着世界石油工业的迅速增长和能源需求的不断增加，原油和成品油的储备受到了普遍关注，对各类油库储备能力的要求也越来越高。20世纪80年代以来，许多国家相继建起了大型陆上和海上石油储备库，我国一大批原油储备库正在陆续建设，而且随着石油进口量的增加，储备量也将相应地逐渐加大，各类储罐的数量剧增。储罐在国民经济发展中所起的作用是无可替代的，不仅石油、化工、国防、交通运输等领域，甚至我们的日常生活，均离不开大大小小的储罐。特别是石油石化企业，无论是大陆或海洋开采的原油，还是炼油厂加工炼制的成品油，不论是长输管道的泵站、运销油库和军用油料油库，还是国家物资储备与战略储备，都需要建设储油设施，都离不开各种容量和类型的储罐。而且，储罐工程投资在石油石化基本建设投资中占有相当大的比例。中国快速发展受石油资源的限制，我国近年来要进口1.6亿吨左右石油，以满足国民经济高速发展的需要，加快发展大型储罐的建设提高我国石油储备能力成为我国战略发展方向。因此，对原油储罐的研究与设计对国民经济有着十分重要的意义。 本文是100000m3外浮顶原油罐的设计说明，本文主要阐述了外浮顶油罐的工艺设计、罐壁的设计、浮顶的设计、罐底的设计、地基的设计、地震、风载校核、防腐的设计等。罐壁厚度的计算采用变点法，地基的设计要考虑到地震的影响，防腐的设计要考虑到罐的内腐蚀和外腐蚀，防腐时采用的防腐漆是否合理和是否经济并考虑涂漆的技术和方法，罐壁和罐底要考虑焊接要求等。 关键词：原油储罐；浮顶；强度；安全 Abstract With world oil industrys rapid growth and increasing energy demand, crude oil and refined oil reserves has attracted extensive attention on the various types of tank storage capacity requirements higher and higher.Since the 80s of the 20th century, many countries have built large-scale onshore and offshore oil reserves, libraries, my library a large number of crude oil reserves are gradually building, and along with the increase in oil imports, reserves will be gradually increased accordingly,dramatic increase in the number of various types of tanks.Tank in national economic development role is irreplaceable, not just petroleum, chemical, defense, transportation and other fields, and even our daily life, are inseparable from the large and small tanks.Particularly petroleum and petrochemical companies, whether continental or marine crude oil, refinery processing or refining of oil products, both long-distance pipeline pumping stations, oil depots and military fuel distribution depot, or to state material reserves and strategic reservesall need to build storage facilities, are inseparable from the storage tanks of various capacities and types.Moreover, investment in petroleum and petrochemical storage project capital investment plays a significant proportion.Chinas rapid development of oil resou
