title: Precipitate containing norm in the oil industry: modelling and laboratory experiments.
abstract: In this work, the influence of factors that can affect the precipitate (scale) containing NORM (radium) in the oil industry is studied. From the experimental results, a mathematical model for calculating the precipitate is proposed. The statistical tests used to obtain this model show that precipitation: does not depend on the shaking velocity and contact time, depends on the temperature and mixing water ratio. Also, it depends on the interactions between temperature and mixing water ratio. The comparison of the experimental results and those obtained by the model appear to be in good agreement.
