热含蜡原油管道经济清蜡周期计算

针对热含蜡原油管道低输量下运行现状,在原有经济清蜡周期模型基础上考虑余蜡厚度的影响,建立了含清蜡周期和余蜡厚度两个自变量的最优清蜡周期模型.指出在求解出给定余蜡厚度和清蜡周期下管输油品的单位总能耗后,采用对分法计算某一余蜡厚度下的最优清蜡周期,再通过改变余蜡厚度方法,可以确定最优余蜡厚度和管道的最优清蜡周期.

Investigation on the Optimization Pigging Period of Buried Hot Waxy Crude Pipeline

For the buried hot waxy crude pipeline running at low flux, the new best pigging period model is established based on old pigging period model, which consider paraffin deposit thickness. The model's economy object function has two variables, pigging period and paraffin deposit thickness. In the course of solving this model,the first step is to calculate oil pipeline unit transportation cost at given paraffin deposit thickness and pigging period, the second step is to calculate optimization pigging period at given paraffin deposit thickness using the halving way,and the last step is to determine the optimization pigging period and paraffin deposit thickness by means of changing the rest paraffin deposit thickness.
