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…
It is also necessary to control the gas/liquid interface or the oil/water interface in process equipment. This is done with a level controller and liquid…
A vessel may be subject to more than one condition under different failure scenarios. For example, a low pressure separator may be subject to blocked…
A pipe that releases gas to disperse into the atmosphere is called a vent. If the gas is burned at the tip, it is called…
The oil must be held at temperature for a specific period of time to enable de-emulsifying the water-in-oil emulsion. This information is best determined in…
The droplet diameter is the most important single parameter to control to aid in water settling since this term is squared in the settling equation.…
Water Treatment describes choosing a process for this subsystem, including vessel and open drains. Figure 2-13 shows an enlargement of the watertreating system for the…
To assure that the liquid and gas reach equilibrium at separator pressure a certain liquid storage is required. This is defined as “retention time” or…
Figure 5-3 shows an alternate configuration known as a “bucket and weir” design. This design eliminates the need for a liquid interface controller. Both the…
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…
