Disposal piles are large diameter (24- to 48-inch) open-ended pipes attached to the platform and extending below the surface of the water. Their main uses…

It can be shown mathematically that an efficient design must have a high gas induction rate, a small diameter induced gas bubble, and relatively large…
In dispersed gas units gas bubbles are dispersed in the total stream either by the use of an inductor device or by a vortex set…
Dissolved gas designs take a portion of the treated water effluent and saturate the water with natural gas in a contactor. The higher the pressure…
The gravity settling devices previously discussed make use of closely spaced internals to reduce the distance an oil droplet must rise to meet a coalescing…
In the past, it was common to direct the water to be treated through a bed of excelsior or another similar medium, as shown in…
Equipment manufacturers have modified the CPI configuration for horizontal water flow perpendicular to the axis of the corrugations in the plates as shown in Figure…
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.…
