在纬度偏高的地区或是时值冬春季节,气候寒冷,气温较低,往往会造成原油管道内原油的凝固。为了确保原油外输生产的平稳运行,原油管道的防凝工作,是其安全生产中的工作重点。本文以某油库大口径原油管道为主要实例,对原油管道的防凝措施进行深入地研究。提出并分析了电伴热、集肤热效应电伴热等防凝措施的优劣。 In the high latitudes or the time of winter and spring, the cold climate and low temperatures often result in crude oil pipeline solidification. In order to ensure the smooth operation of crude oil production, the anti-coagulation work of crude oil pipeline is the focus of its safety production. In this paper, a large oil tanker crude oil pipeline as the main example, the crude oil pipeline anticoagulation measures in-depth study. The advantages and disadvantages of the anti-coagulation measures such as electric heat tracing, skin thermal effect and electric heat tracing are put forward and analyzed.
