Method and apparatus for treating oil-water emulsions

   
   

A treater for separating oil from water in an emulsion uses vertical coalescing vanes extending through the oil portion into the water portion. The vanes are made of a conductive material, and are electrically grounded in the produced water, and may be coated or partially coated to promote de-watering. Water droplets coalescing on the faces of the vanes are transported down the vane into the water portion and are removed from the system. In a further embodiment, the vanes extend above the oil portion into the gas portion to facilitate removal of gas entrained in the oil. In another embodiment, at least some of the coalescing vanes are rotatable, allowing external control of the flow of fluid through the treater.

Um treater para separar o óleo da água em um emulsion usa as aletas coalescendo do vertical que estendem através da parcela do óleo na parcela da água. As aletas são feitas de um material condutor, e aterradas eletricamente na água produzida, e podem ser revestidas ou parcialmente revestidas para promover de-watering. As gotas da água que coalescem nas caras das aletas são transportadas abaixo a aleta na parcela da água e removidas do sistema. Em uma incorporação mais adicional, as aletas estendem acima da parcela do óleo na parcela do gás para facilitar a remoção do gás entrained no óleo. Em uma outra incorporação, ao menos algumas das aletas coalescendo são rotatable, permitindo o controle externo do fluxo do líquido através do treater.
