Abstract
The oil and gas industry includes the processes of exploration, extraction, upgrading, separation,
refining, transporting and marketing oil products. After the separation process, water is removed to a
great extent, and only a small percentage is left in the crude oil. When marketing the products, the value
is essential, and therefore a representative sample has to be extracted to determine the quality. This
requires that the water is uniformly distributed throughout the batch when it is evaluated.
FMC Technologies requested a mixing system that would be able to achieve a homogeneous flow in a
pipeline, for a range of parameters. Because a laminar flow is the most challenging to mix, the
parameters which gives the lowest Reynolds number are chosen as a worst case scenario.
By literature studies, it is stated that a uniform mixture can be provided by multiple processes.
Mechanically agitated vessels, static- and power mixing have been analyzed. The static mixer is
evaluated based on the state of the art, and a power mixing system is designed for the worst case
parameters. Calculations are performed to be able to evaluate. It is found that mechanically agitated
vessels are not recommended for in-line mixing and therefore not evaluated further.
Pressure drop is expensive, and this is taken into account when discussing a conclusion. A static mixer
is recommended for Reynolds numbers below 2000 and a main pipe diameter below 0.4 m. No mixing
is required when the Reynolds number reaches a certain peak where the turbulence in the flow is of a
large extent and mixing will happened naturally. Otherwise, power mixing is the suggested method to
provide a homogeneous flow.
