FLOTATION OF FINE OIL DROPLETS IN PETROLEUM

2016-10-17  The design of oil flotation in produced water systems as a unit process is governed by location and discharge regulations. Geographic location, primarily onshore or offshore, dictate the size and weight restrictions, while regulations govern the discharge method and oil content limits. Onshore produced water treatment, due to lack of space and weight constraints, may use a gravity settling tank (e.g. API tank) with long residence time, but due to injection requirements will often use deep bed media filtration to reduce the oil content to very low levels. Flotation cells are not used frequently for onshore produced water treatment. Offshore produced water treatment will commonly use liquid-liquid hydrocyclones followed by a vertical flotation cell to meet discharge specifications, as these two unit processes have high throughput to footprint ratio. A gravity settling tank or deep bed media filter are rarely used offshore. An offshore flotation cell
