1. A demulsifier for demulsifying water-in-oil emulsion passing through the demulsifier, the demulsifier comprising the following combinations:
1 A demulsifier, which is used to demulsify the emulsion in oil. The emulsion passes through the demulsifier, and the demulsifier consists of the following parts:
A) a vertical, usually cylindrical container having an open upper end, a side wall and a lower end, the lower end forming an angled bend, which terminates in an outlet which is at an angle of about 90 degrees with respect to the central axis of the cylindrical container, so as to establish a smooth transition from the inside of the container to the outlet;
A) A vertical, usually cylindrical container with openings at its upper end, side wall and lower end, which is formed as an angled bent elbow and terminates at an outlet oriented at 90 degrees with respect to the central axis of the cylindrical container, thereby establishing a smooth transition from the inside of the container to the outlet.
B) an inlet located in the side wall near the upper end and oriented in a direction tangential to the side wall;
B) an inlet located on the side wall, which is close to the upper end and tangent to the side wall.
C) means for introducing the emulsion into the container through the inlet at a sufficient speed to exert centrifugal force on the emulsion;
C) means for introducing the emulsion into the container through the inlet at a sufficient speed, which will impart centrifugal force to the emulsion.
D) a closing device made of an electrically insulating material for sealing the open upper end;
D) a closing device made of an electrically insulating material for sealing the upper opening.
E) a cylindrical elongated extension connected to the closing device, which extends downward into the interior of the container to a position below the inlet, is concentric with the container and is used to form an annular area with a reduced cross-sectional area adjacent to the inlet, which helps to increase the flow rate to maintain centrifugal force;
E) a cylindrical elongated extension connected to the closing device, which protrudes downward into the container at a position lower than the inlet, is concentric with the container, and functions to form an annular region with a reduced cross-sectional area adjacent to the inlet, thereby increasing the flow rate and maintaining the centrifugal force.
F) a single elongated electrode concentric with the container and extending downward from the elongated extension; and
F) a single extended electrode concentric with the container, the electrode extending downward from the extended portion; also
G) a power supply device connected to the electrode through a wire passing through an opening in the closing device for supplying power to the electrode.
G) a power supply connected to the electrode through a wire, which supplies power to the electrode through an opening in the closing device.
