Abstract: In a method for purifying an oil (8)/water (42) mixture (40), the mixture (40) is fed to a container (48) having an ultrafiltration unit (52) with a membrane (30), and a protective material (50) is added to the mixture (40), which protective material, directly or after chemical reaction with the water from the mixture (40), as a film (62) on the membrane (30), keeps free oil (8) away from said membrane. Purified process water for extracting and/or refining of petroleum (8) is thus produced from process water (42) which is contaminated with petroleum (8). A purification device (64) substantially comprises a container (48) having an ultrafiltration unit (52) with a membrane (30), a feed line (28) to the container (48) and an addition device (27) for protective material (50) in the flow path (56) to the membrane (30).

Abstract: In a method for purifying an oil (8)/water (42) mixture (40), the mixture (40) is fed to a container (48) having an ultrafiltration unit (52) with a membrane (30), and a protective material (50) is added to the mixture (40), which protective material, directly or after chemical reaction with the water from the mixture (40), as a film (62) on the membrane (30), keeps free oil (8) away from said membrane. Purified process water for extracting and/or refining of petroleum (8) is thus produced from process water (42) which is contaminated with petroleum (8). During extraction and/or refining of petroleum (8), the purified process water (42) is used as feed water and/or as desalting water or for reinjection into an oil field (5). A purification device (64) substantially comprises a container (48) having an ultrafiltration unit (52) with a membrane (30), a feed line (28) to the container (48) and an addition device (27) for protective material (50) in the flow path (56) to the membrane (30).

Abstract translation: 在用于净化油（8）/水（42）混合物（40）的方法中，将混合物（40）进料到具有膜（30）的具有超滤单元（52）的容器（48）和保护性 向混合物（40）中加入材料（50），该保护材料直接或与来自混合物（40）的水化学反应后作为膜（30）上的膜（62）保持游离油（8 ）远离所述膜。 因此，用石油（8）污染的工艺用水（42）制造用于石油（8）的萃取和/或精炼的纯化工艺水。 在石油（8）的萃取和/或精炼过程中，纯化的工艺用水（42）用作进料水和/或作为脱盐水或用于再注入油田（5）。 净化装置（64）基本上包括具有隔膜（30）的超滤单元（52）和容器（48）的进料管线（28）和用于保护材料的加料装置（27）的容器（48） 50）流向膜（30）的流路（56）。
