Foam at the interface may occur when gas bubbles are liberated from the liquid. This foam can be stabilized with the addition of chemicals at…
The ASME code requires every pressure vessel that can be blocked In to have a relief valve to alleviate pressure build up due to thermal…
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…
The iron sponge process uses the chemical reaction of ferric oxide with H2S to sweeten gas streams. This process is applied to gases with low…
The flow rate for gas through a given orifice area or the area required for a given flow rate is obtained by:
Numerous processes have been developed for gas sweetening based on a variety of chemical and physical principles. These processes can be categorized by the principles…
Equipment manufacturers have modified the CPI configuration for horizontal water flow perpendicular to the axis of the corrugations in the plates as shown in Figure…
Vessel Supports Small vertical vessels may be supported by angle support legs, as shown in Figure 12-11. Larger vertical vessels are generally supported by a…
Produced wellhead fluids are complex mixtures of different compounds of hydrogen and carbon, all with different densities, vapor pressures, and other physical characteristics. As a well stream flows from the hot, high-pressure petroleum reservoir, it experiences pressure and temperature reductions. Gases evolve from the liquids and the well streamchanges in character.
It is normally a good idea to include a simple vortex breaker as shown in Figure 4-9 to keep a vortex from developing when the…
