Inhibitor formulated with linseed mucilage ( Linum usitatissimum ) for mineral scales precipitation control

(Eng) A linseed - based inhibitor ( Linum usitatissimum ) was developed that would control the scale precipitation applying experimental trials. The linseed gel was initially extracted by a hydrolysis process and then different inhibitors were formulated at 30, 40 and 50 %m/V concentrations. In order to study the physicochemical characteristics of each product and the linseed gel. A synthetic water was formulated and a sample of production water from the Oritupano oilfield was collected, they were characterized by physicochemical tests. Subsequently, the inhib ition efficiency of the formulated product was evaluated, considering NACE TM 0374 - 2007, at different doses (10, 55 and 100 ppm). The 50 %m/V inhibitor was the most efficient, obtaining efficiency values between 59% and 95.67% for the production water and 36.67% and 92.22% for the synthetic water, showing that at higher concentration, the efficiency increases. Finally, an analysis of variance (ANOVA) was applied between the formulated inhibitors and a commercial reference inhibitor, obtaining a behavior qu ite similar to the standard inhibitor and demonstrating its efficiency. Concluding that linseed gel - based inhibitors were efficient in mineral scales and salt precipitation inhibition, because in some cases they showed greater efficiencies than the commerc ial product evaluated.
