SUMMARY:

In the oil and gas industry, in offshore and inshore applications, it is of fundamental importance to combat the phenomena and/or effects that affect the oil exploration and production process. High power ultrasound can be of great value to researching solutions and developing the industrial and technological sector as it is an excellent solution to combat carbonation in pipelines, accelerating the precipitation of particles during the flow of oil. This thesis work proposes a high-power ultrasonic reactor as an active mechanism in the precipitation of calcium carbonate. Ultrasound delays the nucleation of crystals, making it difficult for particles to join during flow. Therefore, there will be a lot of smaller particles closer to the ultrasonic reactor compared to other regions along the pipeline. In this work, he shows the laboratory tests for the development and calibration of the ultrasonic reactor, the distribution of the ultrasonic field and how regions of higher ultrasonic pressure from a simulation software. It is also presented a proposal for an experiment carried out in Rio de Janeiro, at NIDF - Interdisciplinary Nucleus of Fluid Dynamics, in the multipurpose line of studies of calcium carbonate. The tests showed relevant results in reducing the size of the carbonate crystals and the pressure in the completion valve remained practically stable up to 0.107 bar up to 120 minutes.
