Separators
Two and Three Phase Separator Process Description
The purpose of a Two Phase Separator is to divide
the two phase inlet oil-water-gas stream into two
separate phases and in a three phase separator into
three separate phases. In a three phase separator, a
gas phase free of liquid carry-over droplets, an oil
phase free of gas carry-under and water droplets,
and a water phase free of gas carry-under and oil
droplets. Test Separator units usually also provide
metering of the gas, oil and water phases to measure
the production from individual wells.
The effectiveness of gas/liquid and liquid/liquid
separation in Separators is a function of many
factors. Physical properties such as individual
phase density and viscosity are directly related to
separation efficiency, while factors such as wax
content, foaming tendency, surface tension, solids
content and emulsion stability have a major
influence on the design and selection of appropriate
internals. Additional, external, factors may include
the condition of the feed, for example if it arrives
via a control valve or high velocity pipeline there
is a likelihood that the oil and water will have a
very small droplet distribution size and will be
more difficult to separate. Motion effects, such as
are experienced on floating production systems, also
need to be considered.
Various design features and internal devices are
employed to enhance, accelerate or otherwise improve
the efficiency of the separation process from
knowledge of the above factors.
