Method and apparatus for separating oil-water mixtures in which the oil is present as droplets so as to comprise the disperse phase, the mean droplet size being greater than 56.7 microns, using a cyclone separator having a swirl coefficient, S, in the range S' </= s </= S<u2>, where S' = -0,46 PHI + 31 or S' = 2, whichever is the greater, and S<u2> = 0.26 PHI + 31.6, where PHI is the meand droplet size in micron. The swirl coefficient is defined as pi di d2/4Ai, where di is the effective diameter at the inlet to the separator, d2 is the nominal separator diameter at a downstream location, and Ai is the total effective inlet area. |
