摘要
针对任京线生产运行中存在的能耗高、正反输流程切换频繁等问题,研究了大庆冀东混合原油的基本物性和流变特性,筛选出针对大庆冀东混合原油的最佳降凝剂,确定了降凝剂的添加浓度和热处理温度等工艺条件,计算了任京线加降凝剂单向运行的最低输量,制订了任京线加降凝剂单向运行方案和部分季节加降凝剂单向运行方案,并对任京线正反输运行和加降凝剂单向运行的管道安全性和经济性进行了分析。
Aimed at solving the problems of high energy consumption and frequently switching between forward and backward transportations in Ran-Jing Pipeline operation,the basic physical and rheological characteristics of Daqing crude oil mixed with Jidong crude oil were investigated.The optimum pour point depressant(PPD)for the mixed crude oil was selected,and the PPD concentration,heating treatment temperature and lowest one-direction oil throughput were confirmed.The one-direction operation schemes of Ran-Jing Pipeline by adding PPD for whole year and for seasons were also established,the pipeline security and econo-my in two-direction operation and one-direction operation by adding PPD were analyzed.
