The design pressure for a vessel is called its “Maximum Allowable Working Pressure” (MAWP). In conversation this is sometimes referred to simply as the vessel’s…
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…
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…
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…
A drain system that is connected directly to pressure vessels is called a “pressure” or “closed” drain system. A drain system that collects liquids that…
The flow rate for gas through a given orifice area or the area required for a given flow rate is obtained by:
The molecular weight of the liquid stream is calculated from the weighted average liquid component molecular weight given by: This is calculated in Table 3-3.…
In selecting an exchanger, one must know the advantages and disadvantages of each type. The three basic types of shell-and-tube exchangers are fixed tube sheet,…
Erosional flow criteria will almost always govern in choosing the diameter. Sometimes it is necessary to check for pressure drop in the coil. Typically, pressure…
Heat-exchanger tubes should not be confused with steel pipe or other types of pipe that are extruded to steel pipe sizes. The outside diameter of…
