Three phase separator are designed as either horizontal or vertical pressure vessel. Figure 5-2 is a schematic of a horizontal separator. The fluid enters the…
Figure 5-6 shows a typical configuration for a vertical three-phase separator. Flow enters the vessel through the side as in the horizontal separator, the inlet…
Some treaters use an electrode section. Figure 6-11 illustrates a typical design of a horizontal electrostatic treater. The flow path in an electrostatic treater is…
The Reynolds number is a dimensionless parameter that relates the ratio of inertial forces to viscous forces. It can be expressed by the following general…
Choking, or expansion of gas from a high pressure to a lower pressure, is generally required for control of gas flow rates. Choking is achieved…
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 design pressure for a vessel is called its “Maximum Allowable Working Pressure” (MAWP). In conversation this is sometimes referred to simply as the vessel’s…
Adding heat to the incoming oil/water stream is the traditional method of separating the phases. The addition of heat reduces the viscosity of the oil…
Back-pressure can affect either the set pressure or the capacity of a relief valve. The set pressure is the pressure at which the relief valve…
Direct-fired combustion equipment is that in which the flame and/or products of combustion are used to achieve the desired result by radiation and convection. Common…
