In vertical separators, a minimum diameter must be maintained to allow liquid drops to separate from the vertically moving gas. The liquid retention time requirement…
A scrubber is a two-phase separator that is designed to recover liquids carried over from the gas outlets of production separators or to catch liquids…
Separator operation can be adversely affected by an accumulation of paraffin. Coalescing plates in the liquid section and mesh pad mist extractors in the gas…
A bed of random packing typically consists of a bed support (typically a gas injection support plate) upon which pieces of packing material are randomly…
Aerial coolers are often used to cool a hot fluid to near ambient temperature. They are mechanically simple and flexible, and they eliminate the nuisance…
It should be clear from the description of LTX units that the lower pressure separator in an LTX unit is a simple form of cold-feed…
The purpose of the gas separation section of the vessel is to condition the gas for final polishing by the mist extractor. From field experience…
Pressure Relief Devices All pressure vessels should be equipped with one or more pressure safety valves (PSVs) to prevent overpressure. This is a requirement of…
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…
It is very rare that flow must be controlled in an oil field process. Normally, the control of pressure, level, and temperature is sufficient. Occasionally,…
