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…
Cyclone separators are designed to operate by centrifugal force. These designs are best suited for fairly clean gas streams. The swirling action of the gas…
A kinetic inhibitor is a polymeric chemical that, when added to a production stream, will not change the hydrate formation temperature but will delay the…
A typical spherical separator is shown in Figure 4-3. The same four sections can be found in this vessel. Spherical separators are a special case…
Choking, or expansion of gas from a high pressure to a lower pressure, is generally required for control of gas flow rates. Choking is achieved…
Adding heat to the incoming oil/water stream is the traditional method of separating the phases. The addition of heat reduces the viscosity of the oil…
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 units are designed to allow hydrates to form and to melt them with the heat of the incoming gas stream before they can plug…
If the flow rate of the inlet stream is known in moles per day then the number of moles per day of gas flow can…
In many refineries most of theC4’s and lighter are removed from the atmospheric column overhead distillate in the first column of the light end unit.…
