摘要
为了研究保温热油管道正输、正反输不同投产过程对温度场的影响,在地温、输量、总传热系数等条件完全相同的情况下,采用热油管道投产计算软件,以天津港-华北石化原油管道投产为例,分别对正输、正反输投产过程各站间的进站温度以及各站发生停输时的安全停输时间和停输温降速率等参数进行模拟计算。结果表明:在各站进站温度相同的条件下发生停输时,正反输投产过程各站的安全停输时间比正输投产过程长,停输温降速率比正输投产过程低,推荐采取正反输送的方式加强热油管道投产的安全性。
In this paper, the commissioning of Tianjin port-Huabei Petrochemical crude oil pipeline was taken as an example to study the effect on temperature field by different commissioning processes of insulated hot oil pipelines, i.e., forward transportation, or forward and reverse transportation. The inlet temperature of each station in the commissioning processes of forward transportation and forward and reverse transportation and the safety shutdown time and temperature drop rate in the case of shutdown of each station during the commissioning were simulated and calculated using the hot oil pipeline commissioning calculation software while temperature, transportation rate and total heat transfer coefficient are kept the same. It is shown that when the stations satisfying the same conditions of inlet temperature are shut down, the stations in the commissioning process of forward and reverse transportation are longer than the ones in the forward commissioning process in safety shutdown time and lower in shutdown temperature drop rate. It is recommended to adopt the mode of transportation to strengthen the commissioning safety of hot oil pipelines.
