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…
Dissolved gas designs take a portion of the treated water effluent and saturate the water with natural gas in a contactor. The higher the pressure…
In order to choose the coil length and diameter, a temperature must first be chosen upstream of the choke; the higher Th the longer the…
For stripping service, as in a glycol or amine contactor , bubble cap trays are the most common. In recent years, there has been a…
Tube holes cannot be drilled very close together, since this may structually weaken the tube sheet. The shortest distance between two adjacent tube holes is…
The process of coalescence in water treating systems is more time dependent than the process of dispersion. In dispersions of two immiscible liquids, immediate coalescence…
The molecular weight of the stream is calculated from the weighted average gas molecular weight given by: The molecular weight of the gas stream of…
The first form of a plate coalescer was the parallel plate interceptor (PPI). This involved installing a series of plates parallel to the longitudinal axis…
The oil must be held at temperature for a specific period of time to enable de-emulsifying the water-in-oil emulsion. This information is best determined in…
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…
