【摘要】：南三油库于现有24座大型储油罐,其中,5万立方米储油罐12座,10万立方米储油罐2座,15万立方米储油罐10座,设计储量已达到230万立方米,其它主要生产设施有:输油泵房3座;原油计量间3座;消防泵房1座;锅炉房1座;变电所1座;俄油接卸栈桥1座,汽车装车场1座。油库主要负责接收、计量大庆油田采油一至六厂和九厂原油,同时担负向东北石油管道公司、大庆联谊石化股份有限公司外输原油,并计量交接任务,担负进口俄油储运、计量、输送等任务。在输送和储存过程中,原油周转周期相对较长,储罐温降相对增大,因此,随着原油温度下降,输油管线极易凝堵,导致输油泵频率加大,输油泵运行时耗电会有所上升,其输送能力和承受压力有所下降,将导致全线生产能耗增多的问题,并且全线生产存在一定的风险。因此,为了保证原油安全、高效的输送到目的地又能减少运输成本,做好储罐的运行方式,达到即完成输油任务,又节能降耗的目的。油库输油系统的主要设备包括:储油罐及其附属设备、输油泵及其附属设备、加热炉及其附属设备等。文章首先分析了储油罐的类型,并通过列表格的方式,对大庆原油和俄罗斯原油的物性和类别进行了对比。通过串联运行和并联运行两种情况,说明了储油罐的最优运行方式。而通过储油罐及其附属设施、输油泵和加热炉及其附属设施夏季和冬季不同的运行方案以及事故解决方案的分析,得出了冬季和夏季、不同油品储运的最优运行方案。介绍了集输队和动力队节能措施的应用,对影响运行效率的设备进行了改造、更换,并制定出了南三油库输油系统节能降耗的方案,并且通过对近两年的能耗对比,展示了所取得的节能降耗效果。
[Abstract]:Nan3 Oil Depot has 24 large oil storage tanks, of which 12 are 50, 000 cubic meters, 2 are 100000 cubic meters and 10 are 150000 cubic meters. The designed reserves have reached 2.3 million cubic meters. Other main production facilities are: oil pump room 3; crude oil metering room 3; fire pump room 1; boiler room 1; substation 1; Rosneft unloading trestle 1; truck loading yard 1. The oil depot is mainly responsible for receiving and measuring crude oil from No. 1 to No. 6 and No. 9 plants in Daqing Oilfield, and at the same time it is responsible for exporting crude oil to the Northeast Petroleum Pipeline Company and Daqing Lianyi Petrochemical Co., Ltd., and responsible for measuring the transfer of oil and taking charge of importing Russian oil storage and transportation. Metering, conveying, etc. In the process of transportation and storage, the turnover period of crude oil is relatively long, and the temperature drop of storage tank is relatively increased. Therefore, with the decrease of crude oil temperature, the oil pipeline is easily clogged, which leads to the increase of the frequency of the oil pump and the increase of the electricity consumption of the oil pump when it is in operation. The decrease of transportation capacity and pressure will lead to the increase of energy consumption in the whole production line, and there are some risks in the whole line production. Therefore, in order to ensure the safety of crude oil, the efficient transportation to the destination can reduce the transportation cost, do a good job of the operation of the storage tank, and achieve the purpose of oil transportation, energy saving and consumption reduction. The main equipment of oil transportation system includes: oil storage tank and its auxiliary equipment, oil pump and its accessory equipment, heating furnace and its auxiliary equipment, etc. In this paper, the types of oil storage tanks are analyzed, and the physical properties and types of Daqing crude oil and Russian crude oil are compared by tabulation. The optimal operation mode of oil storage tank is illustrated by two cases of series operation and parallel operation. Through the analysis of different operation schemes of oil storage tank and its auxiliary facilities, oil pump and heating furnace and its auxiliary facilities in summer and winter, as well as the analysis of accident solution, the optimal operation scheme of different oil storage and transportation in winter and summer is obtained. This paper introduces the application of energy saving measures for gathering and transporting teams and power teams, reconstructs and replaces the equipment that affects the operation efficiency, and formulates a scheme for energy saving and consumption reduction in the oil transportation system of the South No.3 Oil Depot, and compares the energy consumption in the last two years. The effect of energy saving and consumption reduction is demonstrated.
