减少原油储罐罐底沉积物的措施

Measures to Reduce the Bottom Sediment of Crude Oil Storage Tank

原油中含有的蜡质、沥青质、胶质及水等主要物质,在储罐内储存期间,受密度及温度影响,比重较大的组分会自然沉降,下沉后堆积在罐底形成沉积物,对储罐日常运行产生了较大影响。文章通过对原油储罐罐底沉积物的检测及分布情况进行客观分析,对沉积物形成的原因及影响因素进行了总结,从优化储罐收发油工艺及沉积物搅拌方面,提出了减少罐底沉积物的有效措施,以达到提高储罐使用效率、降低油库运行风险的目的。

The main substances contained in crude oil,such as wax,asphaltene,gum and water,during storage in the tank,affected by density and temperature,the larger proportion of the group will naturally settle,accumulate at the bottom of the tank to form sediment after sinking,which has a great impact on the daily operation of the tank.Based on the objective analysis of the detection and distribution of the bottom sediment of the crude oil storage tank,the paper summarizes the causes and influencing factors of the formation of the sediment,and puts forward effective measures to reduce the bottom sediment from the aspects of optimizing the process of sending and receiving oil and sediment mixing,so as to improve the use eff iciency of the storage tank and reduce the operation risk of the oil storage tank.
