The maximum allowable stress values to be used in the calculation of the vessel’s wall thickness are given in the ASME Code for many different…
One method of assuring that hydrates do not form is to assure that the amount of water vapor in the gas is always less than…
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…
The most important safety devices in a production facility are the pressure relief valves, which ensure that pipes, valves, fittings, and pressure vessels can never…
The iron sponge process uses the chemical reaction of ferric oxide with H2S to sweeten gas streams. This process is applied to gases with low…
In the past, it was common to direct the water to be treated through a bed of excelsior or another similar medium, as shown in…
The following formulas are used in the ASME Code Section VIII, Division 1 for determining wall thickness: Wall thickness—cylindrical shells Figure 12-1 defines the various…
Flow regimes describe the nature of fluid flow. There are two basic flow regimes for flow of a single-phase fluid: laminar flow and turbulent flow.…
Nozzles should be sized according to pipe sizing criteria, such as those provided in API RP 14E. The outlet nozzle is generally the same size…
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…
