Pilot-operated relief valves use the pressure in the vessel rather than a spring to seal the valve and a pilot to activate the mechanism. Figure…
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…
Pressure Relief Devices All pressure vessels should be equipped with one or more pressure safety valves (PSVs) to prevent overpressure. This is a requirement of…
When subjected to a magnetic induction B, an elementary volume v of magnetizable substance acquires local magnetization M, where M is the magnetic moment of…
The Reynolds number is a dimensionless parameter that relates the ratio of inertial forces to viscous forces. It can be expressed by the following general…
Several proprietary processes have been developed based on the hot carbonate system with an activator or catalyst. These activators increase the performance of the hot…
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…
Coriolis mass-flow controllers (MFCs) are widely used in the chemical process industries (CPI) for applications that require precise and accurate measurement and control of critical…
As more stages are added to the process there is less and less incremental liquid recovery. The diminishing income for adding a stage must more…
The most commonly used single-well lease treater is the vertical treater as shown in Figure 6-8. Flow enters the top of the treater into a…
