For stripping service, as in a glycol or amine contactor , bubble cap trays are the most common. In recent years, there has been a…
The flow of a compressible fluid through an orifice is limited by critical flow. Critical flow is also referred to as choked flow, sonic flow,…
The factor of proportionality in the previous equations is called theĀ Moody friction factor and is determined from the Moody resistance diagram shown in Figure…
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…
The first step in choosing a water treating system is to characterize the influent water streams. It is necessary to know both the oil concentration…
Liquid carryover and gas blowby are two common operating problems. Liquid carryover occurs when free liquid escapes with the gas phase and can indicate high…
In the interest of energy conversion, process heat can be obtained from a heat recovery unit in which heat is recovered from turbine or reciprocating…
The liquid flow rate in moles per day for a given inlet stream can be determined from Equation 3-17. In our example, for an inlet…
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…
The maximum and minimum design temperatures for a vessel will determine the maximum allowable stress value permitted for the material to be used in the…
