SPE-167578-MS Presented at the SPE Nigeria Annual International Conference and Exhibition, Lagos, Nigeria, 5-7 August. The vessel diameter of approximately 11 ft is driven mainly by the following factors: The calculated corrected residence times (adjusted for nonuniform velocity profiles) for the oil and water phases look reasonable in comparison to the calculated separated phase qualities: The calculated separable droplet sizes (100% removal) for each liquid also look reasonable.The use of a multivane inlet device combined with perforated plates has a beneficial effect on the phase velocity profiles/flow distributions which helps gravity separation performance significantly.

Table 1 shows physical properties of three phase and the mass flow rates at the inlet. It should be noted that the times between levels requirements for the oil phase are more onerous than for the water phase as it is the combined (oil + water) flow rates that are used for the levels in the oil zone, whereas just the water flow rate is used for the levels in the water zone. continuous phase viscosity, g/(cm/sec) = poise, drag coefficient (see Appendix A for calculation), hydraulic diameter, in.

The separation efficiency depends on the droplet size target (e.g 500-micron water and 200-micron oil) distribution in each phase of separation, hence to achieve more efficient separation, internals must be installed inside the separators. The procedure then to calculate the drag coefficient is to calculate the Archimedes number, Ar, as defined in Eq.
