Dispersed Gas Units Separator

A vortex set is used to disperse gas bubbles in the stream on dispersed gas units. The figure above shows a dispersed gas units with hydraulic eductor schematic. Clean water from the effluent is pumped to a recirculation header (E) that feeds a series of venturo eductors (B). Water flowing through the eductor sucks gas […]

Corrugated Plate Interceptor Design

Corrugated plate interceptor (CPI) is the most common parallel plate interceptor in oil facilities. CPI is an improvement of the PPI, CPI take less area for the same particle size removal. The figure above shows down flow CPI diagram. The parallel plates in CPI are corrugated parallel to the flow direction. The plate pack is […]

Plate Coalescers to Improve Gravity Separation

We can use plate coalescers to improve gravity separation process, a plate coalescers can be formed as internal plates on skim tanks or vessels. The plate coalescers configurations are: parallel plate interceptors (PPI), corrugated plate interceptors (CPI), or cross-flow separators. All of these configurations depend on gravity separation. When coalescence occurs, the oil droplets will […]

Foamy Crude in Production Separator

{0 Comments}

The non-water substance appearance in crude is the major cause of foam in crude problems. Those substances will not be removed until the crude enters the separator. The separator must be designed properly to have adequate time or coalescing surface to break the foam. Three major problem of foaming crude in separator is as follow: […]

Defoaming Plates Separator

When the fluid release gas bubbles, foam may appears on the surface. To stabilize this foam we may add some chemicals or we can use defoaming separator. Defoaming separator is typically made from a series of inclined parallel plates. The foam will be forced to flow through these plates.

Phase Separator on Oil and Gas Facilities

{0 Comments}

Fluids outputted by the wellhead are made of form many different compounds of hydrocarbon and each compound has its own physical characteristic. The fluids flow from high temperature and high pressure reservoir surface facilities so its temperature and pressure will decrease. Gases from the well stream or evolved in liquid will flow in high speed […]

Flame Arrestor Schematic and Installation

The tube inside flame arrestor will prevent a vent flame traveling back into the tank as we can see in the figure above. The common problem with flame arrestor is they can be plugged easily with paraffin, so it must be installed in a position where inspection and maintenance can be done. To prevent the […]

Wire Mesh Mist Extractor

Wire mesh mist extractor is made of stainless steel wire which form a woven mats wrapped into cylinder pack. The working principle is simple, liquid droplet will hit the mat and coalesce. Gas velocity is the main factor to achieve the effectiveness, so the velocity has to be at proper range. If the speed is […]
