Pipe separator with improved separation
View Patent ↗A pipe separator is for separation of fluids, for example separation of oil, gas and water in connection with extraction and production of oil and gas from formations under a sea bed. The pipe separator comprises an extended, tubular separator body having a diameter at inlet and outlet ends that is mainly equal to or slightly greater than a diameter of a transport pipe to which the separator body is connected. A cyclone is arranged upstream of the separator body for separation of any gas present. An electrostatic coalescer is incorporated in and constitutes an integrated part of the separator body.
1. A pipe separator for separation of oil, gas and water in connection with extraction and production of oil and gas from formations under a sea bed, comprising:
an extended, tubular separator body having a diameter at inlet and outlet ends that is mainly equal to or slightly greater than a diameter of a transport pipe to which said separator body is connected;
a separator device upstream of said separator body for separation of gas; and
an electrostatic coalescer incorporated in and constituting an integrated part of said separator body, said electrostatic coalescer including an upper electrode and a lower electrode in a wall of said separator body such that said upper and lower electrodes are to be supplied with an electric voltage so as to establish a vertical electric field within said separator body.
2. The pipe separator according to claim 1 , wherein said separator device comprises a cyclone separator.
3. The pipe separator according to claim 2 , further comprising:
a water seal downstream of said separator body; and
a device in communication with said water seal for drainage of water that is separated out in said separator body.
4. The pipe separator according to claim 3 , further comprising:
another electrostatic coalescer arranged in series with said electrostatic coalescer.
5. The pipe separator according to claim 3 , wherein
said cyclone separator is in communication with a throttle valve that produces high shear for fluid.
6. The pipe separator according to claim 3 , wherein
said cyclone separator is in close proximity to the inlet end of said separator body.
7. The pipe separator according to claim 2 , further comprising:
another electrostatic coalescer arranged in series with said electrostatic coalescer.
8. The pipe separator according to claim 2 , wherein
said cyclone separator is in communication with a throttle valve that produces high shear for fluid.
9. The pipe separator according to claim 2 , wherein
said cyclone separator is in close proximity to the inlet end of said separator body.
10. The pipe separator according to claim 1 , further comprising:
a water seal downstream of said separator body; and
a device in communication with said water seal for drainage of water that is separated out in said separator body.
11. The pipe separator according to claim 10 , further comprising:
another electrostatic coalescer arranged in series with said electrostatic coalescer.
12. The pipe separator according to claim 10 , wherein
said separator device is in communication with a throttle valve that produces high shear for fluid.
13. The pipe separator according to claim 10 , wherein
said separator device is in close proximity to the inlet end of said separator body.
14. The pipe separator according to claim 1 , further comprising:
another electrostatic coalescer arranged in series with said electrostatic coalescer.
15. The pipe separator according to claim 1 , wherein
said separator device is in communication with a throttle valve that produces high shear for fluid.
16. The pipe separator according to claim 1 , wherein
said separator device is in close proximity to the inlet end of said separator body.
