Oil Water Separation

As oil reservoirs mature produced water rates increase and can be over 90 percent of the total fluid flow. Typically oil and produced water are initially separated in a production separator which is essentially a ‘knockout’ tank. This may involve heating or coalescing to ensure the maximum amount of preliminary oil/water separation. The produced water recovered at this stage can contain varying amounts of free oil from 500 to 10,000 ppm. To be allowed to discharge this water safely into the environment, further treatment is necessary.

eProcess supplies a comprehensive range of process packages which utilize at the heart of the system, liquid-liquid hydrocyclones. Furthermore additional conventional ‘add-on’ technologies are also utilized when specific process conditions dictate. This additional equipment requirement recognizes the difficulty of some water treatment systems, and the fact that one single piece equipment can not always meet some of the tough specifications required.
