Specific gravity of a liquid is the ratio of the density of the liquid at 60°F to the density of pure water. API gravity is…
Sand can be very troublesome in separators by causing cutout of valve trim, plugging of separator internals, and accumulation in the bottom of the separator.…
Figure 13-2 shows a cross section of a conventional relief valve and Figure 13-3 is a schematic that shows the valve’s operation. Convention al relief…
Laboratory testing of a particular oil at various temperatures is the most reliable method of determining how an oil behaves. ASTM D 341 outlines a…
Developed by Allied Chemical Company, this process is selective toward removing sulfur compounds. Levels of CO2 can be reduced by approximately 85%. This process may…
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…
A drain system that is connected directly to pressure vessels is called a “pressure” or “closed” drain system. A drain system that collects liquids that…
A vessel may be subject to more than one condition under different failure scenarios. For example, a low pressure separator may be subject to blocked…
Erosional flow criteria will almost always govern in choosing the diameter. Sometimes it is necessary to check for pressure drop in the coil. Typically, pressure…
The flow of a compressible fluid through an orifice is limited by critical flow. Critical flow is also referred to as choked flow, sonic flow,…
