| As society progresses,the industry continues to develop,Oil demand is alsorising,Thereby the environmental pollution caused by the phenomenon of more and moreserious,How can the crude safe, efficient, environmentally friendly, energy-efficienttransportation arouse people’s attention,Followed by the birth of the pipeline transportationindustry,However, although the actual transmission pipeline transportation capacity, safety,environmental protection, and efficient,However, due to the influence of climatic factors,human factors, etc.,To pipeline transportation has brought great difficulties.Based on the correlation properties of crude oil in Northern, transportation constraintsduring the recent years of operating parameters, emergencies and other analysis and researchto optimize the transport of crude oil in northern Shaanxi normal range of allowabletemperature drop, pressure and flow of each pipe section oil program range, special weatherconditions, greatly reducing the probability of pipeline condensate pipe. Temperature dropdue to external input displacement, diameter and other factors, in Northern temperature dropof crude oil per kilometer between0.11-0.26℃, hourly temperature drop at0.39-0.93℃/between. Through the different seasons of crude oil out of the station temperature statisticalanalysis, combined with the pour point crude oil itself, select a start and stop time of thefurnace, effectively reducing the pipeline costs, reduce environmental pollution, usually inmid-May after another furnace disabled In late October have enabled the furnace. Throughthe DRA and raise the amount of oil pumps in parallel situations, power consumption,increase the dose were analyzed to calculate the cost of the pipeline transportation of crudeoil per ton, per ton of oil when filling DRA oil costs between7.87to8.15yuan, whiletransport costs per ton of oil and pump at around2.87yuan, to improve pipeline efficiencyand reduce the cost of providing a basis pipeline. |
