高粘起泡原油游离水脱除器设计及工业试验

处理高粘起泡原油通常采用进站原油先加热，然后进行气液分离，最后进入原油沉降罐进行油水沉降分离的工艺流程。由于加热高含水原油的大量热能被污水带走，造成大量的燃料消耗。胜利油田设计院研制了Pw0．6MPa、φ4000×20116（mm）游离水脱除器并在孤东二号联合站进行了工业试验，成功地将游离水脱除器应用于高粘起泡原油，实施了进站原油先分水后加热的处理工艺，收到显著的经济效益。介绍了处理高粘起泡原油的游离水脱除器的结构、工作原理及工业试验的情况。试验结果表明，该设备的脱水率为82.4％，脱出水中含油100mg／L左右，较好地满足了高粘起泡原油油气集输的需要。

Design and Industrial Test of High Viscosity Forming Crude Free-Water Remover

This article introduces the structure,working principle and industrial test condition of free-water remover in treating high viscosity forming erude.Test result shows that the dehydration rate of the remover is 82. 4%,oil cut in treated water is about 100 mg/L. It meets the needs of gathering-transferring high viscosity forming crude fairly well.
