Abstract
Managing produced water generated from crude oil and natural gas extraction is crucial in mitigating pollution, environmental, and operational risks. Traditional coagulants like aluminum sulfate and iron sulfate effectively treat produced water but pose environmental and health concerns. This study presents a comprehensive evaluation of Moringa oleifera seed coagulation using real produced water from an operating oil field, addressing critical gaps in previous research that relied solely on synthetic water mixtures. The produced water samples were collected from an on-shore oil field in Colombia and treated with a Moringa oleifera coagulant solution, using jar test experiments to evaluate removal efficiency regarding total suspended solids (TSS), oil and greases, and turbidity. The results indicate that the Moringa oleifera coagulant effectively reduces oil and greases, achieving a 81.3% removal efficiency at a concentration of 4.0 g/L. The removal efficiency values for TSS and turbidity were moderate: 33.8 and 40.8%, respectively. The optimal coagulant concentration was 4.0 g/L, beyond which the removal efficiency decreased. A water chemistry analysis showed minimal cation and anion variations, maintaining injection compatibility for enhanced oil recovery applications. Variations in well conditions were also assessed, showing that the coagulant’s performance was better under stable conditions but faced reduced efficiency in the face of increased contaminant levels. Specifically, TSS removal improved slightly under high-load conditions, while the oil and greases removal efficiency decreased significantly under dynamic field conditions. This study concludes that Moringa oleifera is a promising sustainable alternative to conventional coagulants for produced water treatment from oil reservoirs, offering environmental benefits and a potential for large-scale industrial applications, although further assessment is required to confirm economic feasibility.
