Abstract
El invento se refiere a métodos para tratar el fango del fondo y las emulsiones de interfaz de agua-aceite presentes en una cuba de contención, inyectando en el fango una cantidad de resolución eficaz de un demulsificante a base de aceite. En una realización preferida, la cuba de contención es un desalificador que contiene una capa de fango al fondo, una capa de agua dulce-salada, una capa de emulsión de interfaz de agua-aceite y una capa de hidrocarburo, y el demulsificante se inyecta a través del agua cabezal de lavado de fangos.The invention relates to methods of treating bottom sludge and water-oil interface emulsions present in a containment tank, by injecting into the sludge an effective resolution amount of an oil-based demulsifier. In a preferred embodiment, the containment tank is a desalifier containing a bottom mud layer, a fresh-salt water layer, a water-oil interface emulsion layer, and a hydrocarbon layer, and the demulsifier is injected through the water sludge washing head.
