Description
技术领域
本发明涉及一种分离一种流体，尤其是分离油，气体和水用的方法和装置，该方法和装置与由地面下的地层或海床提取这种流体相关联，包括一个呈管形分离器壳体，一个重力罐或类似的形式的分离器。
背景技术
申请人本人的挪威专利申请No.1994244、20015048、20016216、20020619和20023919描述现有技术管子分离器，使用于在海床上，在地面上，在一个平台或类似物上油、水和或井下气体的分离，在其中使用不同系统解决方案，包括组合管子分离器和其它分离设备，这些方案提供分离技术的一个重要的发展，尤其是对于油和水的分离。
在试验中，除了与上述专利解决方案的发展有关联的其它情况之外，还发现将在下面进一步详细解释的，有可能在分离之前借助添加水至油/水流体中在某些情形下可改进油/水分离。此外，可以发现，在分离之前使流体经受剪力，能够达到较快的相倒转，也就是由含有在一个油相内弥散水的一种混合物的开始流体，更快地转变为水和油的分离层。
发明内容
针对此背景，按照本发明的方法的特征在于，分离器上游的流体经受剪力，从而使供给流的液滴撕裂为这样小的小液滴，使界面通常变为新的和“未被表面活化剂污染的”，如所附权利要求1所述。
按照本发明装置的特征在于，呈一个阀或类似器件形式的一个相倒转装置，设置在运输管内分离器的上游，如所附权利要求5所述。
从属权利要求2-4和6限定本发明的优选的实施例。
附图说明
本发明将借助实例以及参见附图进一步详细地说明，附图中：
图1示出一台设备的一个简单草图，该设备带有油管和水管，它们合聚成为一条流体管，在其中油和水混合。流体管连接至一个重力分离器。
图2示出与图1内相同的设备，但是一个器件插入在分离器的上游，使流体经受剪力，该器件例如是一个适当的阀或类似器件。
具体实施方式
如以上所述，图1示出一个试验装置的一个简单草图，在其中水和油传送通过管子2，3，在一个混合器件4内混合(该器件可能是一个扼流阀或混合管)以及作为一种流体传送至一个分离器1，该分离器是一个普通重力分离器的形式，设计为一个圆筒罐。在分离器1上游是供给水用的一条供水管。
因此，在原则上，理论上有可能借助添加水改进流体的油/水分离，以及因此增加水份至例如70-75％，这样一来，流体必定是水连续的。
当如图内所示，借助添加水直接至流体这样做时，试验显示效果是不稳定的和不可靠的，因为通常没有达到正面的效果。
下面的图解示出，在混合水至75％之前借助比较离开分离器油内的水分％与进入分离器油内的水分％显示的水循环的效果。图解显示，当原始流是油连续的[＜＝60％WC C WC表示水分]，没有达到显著的分离，即使水添加至水分总量75％。如果原始流是水连续的(WC＞60％)，分离是迅速的和有效的，如同对于水连续系统预期的。在原始水分为75％的情形下，流体分离下降至出口水分为约2％。在图解中的全部点属于添加“循环水”后水分总量至75％。
当一个器件(在下文内称为相倒转稳定器)制成为施加剪力至流体的一个阀或类似器件6的形状，该器件插入在分离器1的上游的运输管4内，如图2内所示，循环水对于油/水分离的作用证明是稳定的和可靠的。下面的图解示出带有和没有流体相倒转稳定器6时借助比较离开分离器油内的水分％与进入分离器油内的水分％显示的水循环的效果。如图所显示，离开分离器的一个水分低于约5％是在原始流体的整个水分范围内(15-75WC)达到的。
相倒转稳定器是使流体经受剪力的一个器件。该器件最重要的标准和功能如下：
1.剪力必须足够高，以保证供给流内的液滴撕裂为这样小的液滴，使界面通常变为新的和“未被表面活化剂污染的”，该表面活化剂经常存在于原油系统内。因此新的界面非常不稳定和液滴开始一个强烈、急剧的粗粒化过程，该过程导致相倒转。
2.当大液滴撕裂成为较小液滴时，油和水之间的表面区增加。当撕裂至正好为原始直径的1/3时，新的液滴将是不稳定的，以及“相倒转稳定器”将起作用。
3.典型的工作参数将是撕裂原始液滴至小于原始液滴直径约10％。这样产生一个稳定的相倒转过程。
这种“相倒转稳定器”的最简单的实际设计是一个尖锐边缘阀(球阀或类似器件)。如果在运输管内相倒转稳定器的上游平均液滴尺寸为约1000μm，通过阀的约为1至1.5bar的一个压力降将会大于用于稳定的相倒转足够的压力降。
如在权利要求书内限定的本发明，不应局限于附图中所示的和以上说明的实例，某些原油，例如在通过管子运输时可以是油连续的，带有70-80％水分。这样的流也可以借助相倒转稳定器变成水连续的。要求是对一个系统在油内的水分足够高，以便当它相倒转时保持是水连续的。加入去乳化剂能够防止相倒转的流体倒回为油连续的。
