摘要油库是接收、储存、发放石油或石油产品的独立企业或单位。它是协调原油生产、原油加工、成品油供应及运输的纽带，是国家石油储备和供应的基地，也是我国现代化建设和军队后勤建设的重要组成部分。它对于保障国防和促进国民经济高速发展具有相当重要的意义。由于石油工业的快速进步和石油战略地位的不断提高，油库的建设也越来越重要。本设计将根据设计任务书，在B油田联合站附近拟建一座原油库，以便联合站净化油经其中转到相向的外输首站及炼油厂。在综合运用所学的专业知识的前提下，查阅了有关原油库各操作单元设计和计算的规范及文献。本设计阐述了设计思路和相关理论，介绍了主要运用到的计算公式、计算结果；详细说明了原油库各操作单元的计算过程，并设计了该油库的总平面布置图和工艺流程图。本设计主要包括总平面布置、工艺流程及消防系统设计和计算、自动化控制概念设计等方面。本油库的总平面布置符合有关规范规定，工艺设计合理、且完全满足任务书规定的收发油及储存作业要求。关键词：原油库；工艺设计；平面布置；设备；油田ABSTRACTOildepotisanindependententerpriseorcompanytoreceive,storeanddistributepetroleumorpetroleumproducts.Itisalinktocoordinatetheproductionandprocessingofcrudeoil,andthesupplyandtransportationofpetroleumproducts.Itisabaseofthenationaloilreservesandsupply.Itisaswellasanimportantcomponentpartofthenationalmodernizationandarmylogisticconstruction.Ithasanimportantsignificancetoguaranteethesafetyofnationaldefenseandpromotetherapiddevelopmentofnationaleconomy.Withtherapidlyprogressingofoilindustryandtherisingofthestrategicpetroleumstatus,theconstructionofoildepotisalsobecomingincreasinglyimportant.Accordingtothedesigntask,acrudeoildepotBnearbyacombinedstationisbeingtobeconstructed.SothatthepurifiedcommercialcrudeoilscanbetransportedoutofthedepotBtotheterminalstationandarefinerylocatingattheoppositedirection.Undertheconditionofcomprehensivelyusingtheprofessionalknowledge,therelatedcriteriaandreferencesonthedesignandcalculationofeachoperationunitforthecrudeoildepotwerestudied.Thisdesignmainlyexpoundsthedesignthinking,relatedtheories,andintroducesthemaincalculationformulaandresults,anddescribesindetailthecalculationstepsofeachoperationunit,andpresentstheoverallplanelayoutandprocessflowdiagram.Thisdesignmainlyincludesthedesignofoverallplanelayout,processflowandfirefightingsystemdesignandcalculation,andtheconceptdesignofautomatecontrolsystem.Theoverallplanelayoutmeetstheprescriptionofrelatedcriteria,theprocessflowdesignisreasonableandcompletelymeetstherequirementsofthereceive,distributionandstorageoperationdemandedbythejobspecification.Keywords:crudeoildepot;processdesign;overallplanelayout;equipment;oilfield目录1绪论.......................................................................................11.1设计的背景及目的............................................................11.2国内外研究现状................................................................21.3设计原始数据...................................................................31.4设计要求..........................................................................41.5设计过程..........................................................................51.5.1总平面布置...............................................................51.5.2工艺流程设计...........................................................61.5.3加热系统设计...........................................................71.5.4消防系统设计...........................................................71.5.5自动化控制概念设计.................................................81.5.6设计基础数据...........................................................82总平面布置..............................................................................102.1油库容量........................................................................112.2油库的分级和分区..........................................................132.3储油区............................................................................152.4装卸区............................................................................202.5辅助生产区.....................................................................202.6行政管理区.....................................................................212.7污水处理设备.................................................................222.8库内道路........................................................................223工艺流程设计与计算................................................................243.1工艺流程设计.................................................................243.1.1水力部分................................................................263.1.2泵房工艺流程.........................................................293.2水力计算........................................................................323.2.1经济流速................................................................323.2.2任务输量................................................................323.2.3管径.......................................................................333.2.4实际流速................................................................343.2.5沿程摩阻................................................................353.2.6局部摩阻................................................................373.2.7总水力摩阻.............................................................383.3泵房工艺计算.................................................................383.3.1泵的流量................................................................383.3.2泵的扬程................................................................383.3.3校核泵与管路的工作点...........................................383.3.4泵的允许吸入高度..................................................393.3.5泵的允许安装高度.........................................
