The most common form of parallel plate interceptor used in oil facilities is the corrugated plate interceptor (CPI). This is a refinement of the PPI…
The first form of a plate coalescer was the parallel plate interceptor (PPI). This involved installing a series of plates parallel to the longitudinal axis…
Plate coalescers are skim tanks or vessels that use internal plates to improve the gravity separation process. Various configurations of plate coalescers have been devised.…
The simplest form of primary treating equipment is a settling (skim) tank or vessel. These items are normally designed to provide long residence times during…
The process of flotation improves the separation of the oil droplets from the water continuous phase. This goal is accomplished by increasing the difference in…
The process of coalescence in water treating systems is more time dependent than the process of dispersion. In dispersions of two immiscible liquids, immediate coalescence…
An oscillating droplet of oil becomes unstable when the kinetic energy is sufficient to make up for the difference in the surface energy between the…
Most commonly used water treating equipment items rely on the forces of gravity to separate the oil droplets from the water continuous phase. The oil…
In producing operations it is often necessary to handle waste water that may include water produced with crude oil, rain water, and washdown water. The…
