Figure 6-1 shows a multistage separation process. By removing molecules of the light components in the first separator they are not available to flash to…
The purpose of the gas separation section of the vessel is to condition the gas for final polishing by the mist extractor. From field experience…
In modern refinery practice the distillation of atmospheric residue is accomplished under high vacuum conditions in a specially designed tower whose internal equipment ensures a…
The sensible heat duty for the oil phase is: where Q0 = oil flow rate, bpd SG = oil specific gravity C0 = oil specific…
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…
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 pipe that releases gas to disperse into the atmosphere is called a vent. If the gas is burned at the tip, it is called…
Hydrocarbon streams as produced at the wellhead are composed of a mixture of gas, liquid hydrocarbons, and sometimes free water. In most cases it is…
Remembering that the weight of each component is the number of moles of that component times its molecular weight (pounds = MW X moles), the…
Mist extractors can be made of wire mesh, vanes, centrifugal force devices, or packing. Wire mesh pads (Figure 4-10) are made of finely woven mats…
