Abstract: Provided are embodiments that include an ultrasonic transducer system including an ultrasonic transducer assembly adapted to be disposed in an interior region of an ultrasonic transducer housing, and including a first ultrasonic transducer head adapted to transmit a first set of ultrasonic signals (including a first transmission surface adapted to direct the first set of ultrasonic signals through the first transmission surface), a second ultrasonic transducer head adapted to transmit a second set of ultrasonic signals (including a second transmission surface adapted to direct the second set of ultrasonic signals through the second transmission surface), and a transducer biasing member disposed between the first ultrasonic transducer head and the second ultrasonic transducer head and adapted to bias the first and second ultrasonic transducers in opposite directions to bias the first and second transmission surfaces against opposite portions of an interior surface of the ultrasonic transducer housing.

Abstract: Provided are embodiments that include a hydrocarbon fluid processing system including an ultrasonic hydrocarbon degassing unit including a vapor recovery vessel adapted to direct flow of a hydrocarbon fluid mixture along a flowpath extending through an interior of the vapor recovery vessel, and an ultrasonic transducer system disposed inside the vapor recovery vessel and in the flowpath of the hydrocarbon fluid mixture. The hydrocarbon fluid mixture including a hydrocarbon liquid and a gas entrained in the hydrocarbon liquid, the ultrasonic transducer system adapted to transmit ultrasonic signals into the hydrocarbon fluid mixture along the flowpath, and the ultrasonic signals adapted to separate the gas from the hydrocarbon liquid.
