摘要
棕榈油具有易凝固和黏度变化的特性,在长距离管道输送过程中产生温度上升,油脂的黏度和密度降低,影响计量的准确性,在设计中选择高精度的计量仪。基于棕榈油的易凝性,为保证不同品种的棕榈油在管道中安全输送,选用集肤伴热系统,选用清扫装置全线清扫管道剩余油脂。
The freezing point and viscosity of the palm oil easily change,the palm oil will decrease the viscosity and density as the temperature is going up in long distance piping transportation that affects the accuracy of the measurement instrument,the higher accuracy metering instrument must be used in the process design.As the freezing point easily changes,in order to ensure the safe transportation of the variety of palm oils,the skin effect current trace system for the piping was selected,and the pig launch and receiver were used for cleaning the remaining oil inside the pipe after oil transportation.
