Multiphase Separation

Crude oil wells contain oil, gas, water and various contaminants. Frames multiphase separators guarantee adequate separation using state-of-the-art technologies.
The various contaminants must be separated before the oil or gas can be sold, and to avoid negative effects on downstream equipment. To remove gas and water from oil, the mixture is passed through multiphase separators. These separators are fitted with Frames proprietary internals, which enhance separation to the required specification.

About our Multiphase Separators

The crude oil mixture passes through an inlet device to disperse the momentum of the incoming fluids. Primary/bulk separation as well as flow distribution occurs in the inlet section (1). From the inlet section, the fluids are given adequate settling time to allow the heavier phase to settle beneath the light phase, while the degassed gas-phase occupies the free area above the liquids (2). Additionally, liquid/liquid separation enhancer internals such as plate pack coalescers are added to provide stringent performance guarantees. Liquid levels are maintained by weirs and control valves. At the outlet section (3), a gas/liquid separation device is placed (typically a demisting device) which ensures separation of small liquid particles in the gas phase by coalescence. Oil at the specified guarantee level is discharged at the oil outlet nozzle, while water and gas are discharged through their respective outlets.
