Dynamic demulsification system for use in a gas-oil separation plant
A dynamic water/oil demulsification system for a gas-oil separation plant (GOSP) includes: an in-line microwave treatment subsystem upstream of one or more of each of a dehydrator vessel, desalter vessel and/or water/oil separator vessel, each of which vessels receives a water-oil emulsion; sensors that monitor and transmit data corresponding to properties of the water-oil emulsion in or downstream of the respective vessel(s); and a processor/controller associated with the in-line microwave treatment subsystem that initiates the application of microwave energy to the emulsion(s) based on the data from the sensors.
1. An integrated dynamic demulsification system for use in a gas-oil separation plant (GOSP) to facilitate the removal of water from oil, the GOSP including at least a dehydrator vessel in fluid communication with a desalter vessel which in turn is in fluid communication with a water/oil separator vessel, the demulsification system comprising:
a first in-line microwave treatment subsystem upstream of the dehydrator vessel for receiving a water-in-oil emulsion;
a first sensor for the real-time monitoring and transmission of data representing one or more properties of the water-in-oil emulsion in the dehydrator vessel or downstream of the dehydrator vessel and upstream of the desalter vessel, wherein the first sensor is selected from the group consisting of a buoyant structure in the dehydrator vessel that continuously monitors the liquid surface using a high-frequency electromagnetic energy transmitter and/or receiver and an imaging system that generates images of a slipstream downstream of the dehydrator vessel and upstream of the desalter vessel;
a second in-line microwave treatment subsystem upstream of the desalter vessel for receiving a water-in-oil emulsion;
a second sensor for the real-time monitoring and transmission of data representing one or more properties of the water-in-oil emulsion in the desalter vessel or downstream of the desalter vessel and upstream of the water/oil separator vessel, wherein the second sensor is selected from the group consisting of a buoyant structure in the desalter vessel that continuously monitors the liquid surface using a high-frequency electromagnetic energy transmitter and/or receiver and an imaging system that generates images of a slipstream downstream of the desalter vessel and upstream of the water/oil separator vessel,;
a third in-line microwave treatment subsystem upstream of the water/oil separator vessel for receiving a water-in-oil emulsion;
a third sensor for the real-time monitoring and transmission of data representing one or more properties of the water-in-oil emulsion in the water/oil separator vessel or downstream of the water/oil separator vessel, wherein the third sensor is selected from the group consisting of a buoyant structure in the water/oil separator vessel that continuously monitors the liquid surface using a high-frequency electromagnetic energy transmitter and/or receiver and an imaging system that generates images of a slipstream downstream of the water/oil separator vessel; and
a processor/controller is operably coupled to at least one sensor, the at least one sensor providing data to at least one oil-separation program, wherein data from the first, second and third sensors, and the at least one oil-separation program are stored in at least one memory device, the at least one oil-separation program being executable in real time by the processor/controller to:
receive the data from the first sensor and transmit one or more signals to the first in-line microwave treatment subsystem to generate and apply microwave energy of predetermined characteristics to the flowing fluid based on the properties of the emulsion as determined by the first sensor,
receive the data from the second sensor and transmit one or more signals to the second in-line microwave treatment subsystem to generate and apply microwave energy of predetermined characteristics to the flowing fluid based on the properties of the emulsion as determined by the second sensor, and
receive the data from the third sensor and transmit one or more signals to the third in-line microwave treatment subsystem to generate and apply microwave energy of predetermined characteristics to the flowing fluid based on the properties of the emulsion as determined by the third sensor.
