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…
In order to develop a treater design procedure, the water droplet size to be used in the settling equation to achieve a given outlet water…
These are thin diaphragms held between flanges and calibrated to burst at a specified static inlet pressure. Unlike relief valves, rapture discs cannot reseal when…
In condensate stabilizers, trays generally have 70% equilibrium stage efficiency. That is, 1.4 actual trays are required to provide one theoretical stage. The spacing between…
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…
For an emulsion to exist there must be two mutually immiscible liquids, an emulsifying agent, and sufficient agitation to disperse the discontinuous phase into the…
Disposal piles are large diameter (24- to 48-inch) open-ended pipes attached to the platform and extending below the surface of the water. Their main uses…
Figure 4-2 is a schematic of a vertical separator. In this configuration the inlet flow enters the vessel through the side. As in the horizontal…
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…
This is the bottom product from the vacuum distillation unit. Just as in the case of the atmospheric residue it has several options for its…
