磁处理对南海原油凝点的影响规律研究

通过对原油进行磁处理,可以改善原油的流动性,降低其输送成本。通过控制磁化温度、磁化转速和磁化强度,对模拟南海原油油样进行磁处理后凝点变化规律进行了研究。结果表明:磁处理能降低南海原油的凝点,磁化温度、磁化转速和磁化强度对南海原油的凝点均有影响。在40~80℃的温度区间内,磁化温度越高,磁处理降凝效果越好;在0~100 mT的磁场强度范围内,随着磁化强度增加,凝点具有不断降低趋势;最优的磁化转速为1000 r/min,在此转速下,实验油样凝点降低了4.7%。

Study on Effect of Magnetic Treatment on Freezing Point of Crude Oil in South China Sea

By treating crude oil through a magnetic field,the crude oil liquidity can be improved and its transportation cost can be reduced.By controlling magnetization temperature,magnetization speed and magnetization intensity,the change rule of freezing point of simulated crude oil samples in the South China Sea was studied.Results indicate that magnetic treatment can reduce the freezing point of crude oil in the South China Sea,magnetization temperature,magnetization speed and magnetization intensity affected the freezing point of crude oil.In the temperature scope below 40~80℃,the higher the magnetization temperature is,the better the effect of magnetic treatment is.And within the scope of magnetization intensity below 0~100 mT,with the increase of magnetization,the freezing point has a decreasing tendency.The optimal magnetization speed was 1000 r/min,at which the freezing point of the experimental oil sample decreased by 4.7%.
