The Schlumberger WEMCO® PACESETTER separator uses an innovative plate design to remove oil and suspended solids from process streams more effectively and economically compared with other gravity separators. It is distinguished from conventional crossflow separators by its integrated, lattice-type pack structure, which provides excellent strength and rigidity. Influent oil concentrations as high as 800,000 ppm can be reduced to as little as 15 ppm with most suspended solids removed.
PACESETTER separators can be used in a wide range of onshore and offshore applications to remove oil and suspended solids from produced water, wash water, oil tanker ballast water, process wastewater, and storm runoff.
PACESETTER separator is designed for 100% removal of all oil droplets from 40 to 60 um and larger per API Design Manual 421. It uses use a unique two-stage process to remove oil and suspended solids from treated water. First, influent energy is diffused by coalescer and distributor packs, causing small oil droplets to collide and coalesce for easier separation. This is followed by a separator pack of corrugated plates, which provide separate surfaces and flow paths for oil and solids, preventing reentrainment. The removed sludge moves to the bottom of the plates and then drops off into the hopper, where it is discharged intermittently through a blowdown valve.
