Embodiment Construction

[0017] see now figure 1 , figure 1 An onshore separation plant 1 for separating an oil-water-gas mixture into its components at a separation pressure is schematically shown.

[0018] The separation device 1 comprises a first in-line separator 2 for separating gas from the mixture to obtain liquid substantially free of gas and gas with reduced liquid content. The first in-line separator 2 has an inlet 3 suitable for connection with a feed conduit 5 and separate outlets 7 and 9 for gas and liquid respectively.

[0019] The separation device 1 also comprises means 10 for removing gas with reduced liquid content from the gas outlet 7 of the first in-line separator 2 .

[0020] The separation device 1 also comprises a second in-line separator 12 for separating water from the substantially gas-free liquid to obtain substantially oil-free water and substantially water-free oil. The second inline separator 12 has an inlet 15 in fluid communication with the liquid outlet 9 of the fi...

Abstract

A plant for separating a mixture of oil, water and gas produced from a well, the plant comprising a first in-line separator for separating the mixture into a gas stream substantially free of liquid and a liquid stream substantially free of gas, the first in-line separator being provided with an inlet conduit for supplying the mixture to the first in-line separator, a second in-line separator for separating the liquid stream into an oil stream substantially free of water and a water stream substantially free of oil, the second in-line separator being provided with an inlet conduit for supplyingthe liquid stream to the second in-line separator. Each in not line separator comprises a chamber for separating the respective fluid stream supplied to the in-line separator, said chamber having aninternal diameter substantially equal to the internal diameter of the respective inlet conduit of the in-line separator.

Description

technical field [0001] This invention relates to apparatus for separating oil-water-air mixtures into their components at separation pressure. Background technique [0002] Such separation equipment typically includes a feed line provided with a pressure relief valve to allow the pressure of the mixture to be reduced from high pressure to the separation pressure during normal operation, and a plurality of interconnected separator vessels. The separator vessel is large enough to get a good separation. [0003] A disadvantage of this separation device is that the separator vessel must be emptied in the event of a shutdown. To this end, the separation device should be connected to a pressure relief and pressure relief system including a flare so that vapors and liquids can be directed to the flare. Contents of the invention [0004] It is an object of the present invention to provide a separation plant without a separator vessel, but comprising pipes, such that the plant ha...
