This article describes a conceptual design for handling an oilfield’s industrial wastewater; its objective was to use type-I fractioned crystallisation within a feasible environmental and technical framework for obtaining the highest percentage of salt. La Gloria, La Gloria Norte and Morichal (all belonging to the Casanare department association) stations were used for planning and analysing this handling alternative as they produce high salt-containing industrial effluent. This alternative was focused on treating 30% of the total volume of the associated water so produced. This volume is expected to be 1239 m3/d in 2000 in the oilfields being studied here. The process allows 92% retrieval from present NaCl (0.918 Ton/h), having 97% purity. Evaporation and aeration systems should be set prior to the crystallisation stage as a means of guaranteeing final product quality and making good use of the field’s facilities.
En este artículo se presenta el diseño conceptual de una alternativa complementaria de la solución al manejo de las aguas asociadas de producción dentro de un marco ambiental y técnico factible, cuyo fin es la recuperación de la sal de mayor porcentaje, mediante un proceso de cristalización fraccionada tipo I. Para plantear y analizar la alternativa de trabajo con las aguas asociadas de producción provenientes de las estaciones La Gloria, La Gloria Norte y Morichal, pertenecientes a la Asociación Casanare, dado que las anteriores producen un efluente con alto contenido de sales, la propuesta está enfocada al tratamiento del 30% del volumen de agua asociada producida, esperada para el año 2000 (1239 m3/día) en los campos de estudio. El proceso permite recuperar un 92% de NaCl presente, equivalente a 0.918 Ton/h, con una pureza del 97%. Para garantizar la calidad del producto final y aprovechar las facilidades del campo, se proponen sistemas de aireación y evaporación previos a la etapa de cristalización.
