To maintain pressure on a separator, a liquid seal must be effected in the lower portion of the vessel. This liquid seal prevents loss of…
Because of the multicomponent nature of the produced fluid, the higher the pressure at which the initial separation occurs, the more liquid will be obtained…
Balanced relief valves are spring-loaded valves that contain a bellows arrangement to keep back-pressure from affecting the set point. Figure 13-4 shows a cross section…
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…
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…
For stripping service, as in a glycol or amine contactor , bubble cap trays are the most common. In recent years, there has been a…
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…
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…
Before choosing a wall thickness it is necessary to choose a pressure rating for the coil. Typically, the high-pressure coil (L1) is rated for the…
The area of the fire tube is normally calculated based on a heat flux rate of 10,000 Btu/hr-ft2. The fire-tube length can be determined from:…
