The way in which the process temperature is controlled varies. In a heater, a temperature controller measures the process temperature and signals a fuel valve…
Control valves are used throughout the process to control pressure, level, temperature, or flow. It is beyond the scope of this text to discussthe differences…
For an oil and gas separator to accomplish its primary functions, pressure must be maintained in the separator so that the liquid and gas can…
The skim pile is a type of disposal pile. As shown in Figure 7-18, flow through the multiple series of baffle plates creates zones of…
A bed of random packing typically consists of a bed support (typically a gas injection support plate) upon which pieces of packing material are randomly…
This fraction is usually the first side stream of a conventional atmospheric distillation unit. It may be cut to meet a burning oil specification or…
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.…
These processes are based on the solubility of the H2S and/or CO2 within the solvent, instead of on chemical reactions between the acid gas and…
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 specific gravity difference between the dispersed water droplets and the oil should result in the water “sinking” to the bottom of the treatment vessel.…
