- Calculation of scale thickness in oil pipelines using transmission gamma Tâmara Porfíro Teixeira César Marques Salgado Biología MCNP scale X code oil pipelines Transmission gamma Scale can be defined as chemical compounds inorganic, initially insoluble, and which precipitate accumulating in the internal wall of pipes, surface equipment and/or parts of components involved in the production and transport of oil. These compounds, when precipitating, cause problems in the oil industry and consequently result in losses in the optimization of the extraction process. Although the importance and impact of the precipitation of these compounds in the technological and economic scope, there is still the difficulty in determining methods that enable the identification and quantification of the scale at an initial stage. The use of the gamma transmission technique may provide support for a better understanding of the deposition of these compounds, making it a suitable tool for the noninvasive determination of their deposition in oil transport pipelines. The geometry used for the scale detection include a 280 mm diameter iron pipe containing barium sulfate (BaSO4) ranging from 5 to 60 mm, gamma radiation source with divergent beam and as NaI(Tl) 2”x2” scintillation detector. The opening size of the collimated beam was evaluated (2 to 7 mm) to also quantify the associated error in calculating the scale. The study was realized with computer simulation, using the MCNP-X code and validated by means of analytical equations that indicate the possibility of using this study for this purpose. 2020 artículo científico 2319-0612 https://www.redalyc.org/articulo.oa?id=722280926005 en http://www.redalyc.org/revista.oa?id=7222 Brazilian Journal of Radiation Sciences application/pdf Sociedade Brasileira de Proteção Radiológica - SBPR Brazilian Journal of Radiation Sciences (Brasil) Num.3B Vol.8
