长输管道输送原油需要加热。阐述了新型原油加热系统热媒脱水、脱轻馏分的工艺,针对用户在使用热媒炉系统过程中易发生水击,无法实现自动控制和优化运行,热效率低,热媒乳化失效快等问题进行了攻关,发现主要根源是热媒脱水、脱轻馏分工艺操作不合理造成的。经过长期的实验,得出了热媒脱水和脱轻馏分的优化曲线,实现了热媒炉系统的安全、平稳、高效运行。
Long-distance pipeline transportation of crude oil needs heating. The process of dehydration and light fractionation of heat medium in the new crude oil heating system is expounded. In view of the problems of water hammer easily occurring in the process of using the heat medium furnace system, the automatic control and optimization operation can not be realized, the thermal efficiency is low and the heat medium emulsification failure is quick A research, found that the main source of dehydration heat medium, light distillation process unreasonable operation caused. After a long period of experiments, the optimum curves of dehydration and de-light fractionation of the heat medium have been obtained, and the safe, stable and efficient operation of the heat medium furnace system has been realized.
