Resumo:
Hydrates are crystalline compounds formed by the combination of gas molecules with water molecules under specific pressure and temperature conditions. In oil and gas systems, hydrates can form in underwater production lines or transport pipelines, posing a significant challenge to the industry. Hydrate formation occurs when gas molecules, typically methane, are trapped in a crystalline water structure. This can lead to pipeline blockages, resulting in operational and economic challenges. The dissociation of hydrates, on the other hand, releases the gas but may pose safety risks and environmental impacts. The project aims to assess the feasibility of hydrate dissociation using high-power laser technology in scenarios where these crystals form in underwater pipelines. The study’s modeling is conducted on a cross-sectional segment of the pipeline, where hydrate formation can cause partial or total blockages, affecting the flow of oil and gas and leading to production shutdowns. The analysis will be performed using COMSOL Multiphysics, focusing on evaluating heat conduction through the pipeline, with heat generated by the laser at a specific distance from the pipeline. Thus, it will be verified whether it is possible to achieve the temperature required for hydrate dissociation, preventing potential blockages.
