Claims17
A method for controlling an inner tube (40) of an inclined tubular oil and water separator (11a-d) formed by an elongated outer tube (50) within which the inner tube (40) is arranged, the inner tube (40) being configured to receive oil well substances introduced into one end thereof via a feed section passing through the outer tube (50) and into the inner tube (40), the inner tube (40) comprising multiple holes or slots (44) arranged in a longitudinal direction and having an upper end, comprising the steps of:
- (a) providing the inner tube (40) with an outlet (45) at the upper end;
- and
- (b) controlling opening and closing of the outlet (45) according to a viscosity (η) measurement of oil introduced into the inner tube (40).
An inner tube (40) of an inclined tubular oil and water separator (11a-d) formed by an elongated outer tube (50) within which the inner tube (40) is arranged, the inner tube (40) having an upper end and a first end within which oil well substances are introduced via a feed section passing through the outer tube (50) and into the inner tube (40), comprising:
- multiple holes or slots (44) arranged in a longitudinal direction of the inner tube (40),
- an outlet (45) at the upper end, wherein
- the outlet (45) is configured to be controlled to open and close according to a viscosity (η) measurement of oil introduced into the inner tube (40).
