阿拉山口-独山子原油管道停输温降计算

Calculation of Shutdown Temperature Drop on Alashankou-Dushanzi Crude Oil Pipeline

阿拉山口-独山子原油管道自2006年投产以来,已运行5年多,由于管道的计划检修、管线设备的老化、自然灾害或人为因素造成的事故抢修等都可能造成管道的全线停输。本文通过对阿独原油管道现有输量、不同油品物性参数和不同月份平均地温综合考虑,对需加热输送的油品安全停输时间进行计算,得出了不同倾点原油在满足热力输送月份的安全停输时间。

Alashankou-Dushanzi crude oil pipeline has run more than five years since 2006.Scheduled maintenance,aging,natural disasters or accidents are main reasons to cause pipeline shutdown.In this paper,taking into account transmission capacity of Alashankou-Dushanzi crude oil pipeline,physical parameters of different oils and average ground temperature in different month,the safety shutdown time of oil heating transport pipeline was calculated,the safety shutdown time for different pour point crude oil in different month was gained to meet the heating transportation.
