The factor of proportionality in the previous equations is called the Moody friction factor and is determined from the Moody resistance diagram shown in Figure…
Hydrocyclone separators, sometimes called enhanced gravity separators, use centrifugal force to remove oil droplets from oily water. As shown in Figure 7-16, static hydrocyclone separator…
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…
Removing water from crude oil often requires additional processing beyond gravitational separation. In selecting a treating system, several factors should be considered to determine the…
A scrubber is a two-phase separator that is designed to recover liquids carried over from the gas outlets of production separators or to catch liquids…
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…
As with vertical two-phase separators, a minimum diameter must be maintained to assure adequate gas capacity. In addition, vertical threephase separators must maintain a minimum…
The choice of separator operating pressures in a multistage system is large. For large facilities many options should be investigated before a final choice is…
Many times the designer is given the mole fraction of each component in the feed stream but is not given the mole flow rate for…
As shown in Figure 5-2, the well stream enters the first coil at its flowing tubing temperature and pressure. Alternatively, it could be choked at…
