The principal items of construction that should be present in a good liquid-gas separator are the same regardless of the over-al1 shape or configuration of…
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…
Most oil-treating equipment relies on gravity to separate water droplets from the oil continuous phase, because water droplets are heavier than the volume of oil…
It is important to be able to estimate vessel weights, since most cost estimating procedures start with the weight of the vessel. The vessel weight,…
Water Treatment describes choosing a process for this subsystem, including vessel and open drains. Figure 2-13 shows an enlargement of the watertreating system for the…
To assure that the liquid and gas reach equilibrium at separator pressure a certain liquid storage is required. This is defined as “retention time” or…
Flow regimes describe the nature of fluid flow. There are two basic flow regimes for flow of a single-phase fluid: laminar flow and turbulent flow.…
Each relief valve should be equipped with inlet piping no smaller than the valve inlet flange size, and inlet piping should be as short as…
The maximum allowable stress values to be used in the calculation of the vessel’s wall thickness are given in the ASME Code for many different…
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…
