Re-entrainment is a phenomenon caused by high gas velocity at the gas-liquid interface of a separator. Momentum transfer from the gas to the liquid causes…
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…
There are four major types or basic configurations of separators, generally available from manufacturers which are as follows: 1. Vertical 2. Horizontal Single Tube 3.…
To calculate the heat duty it must be remembered that the pressure drop through the choke is instantaneous. That is, no heat is absorbed or…
This process uses propylene carbonate as a physical solvent to remove CO2 and H2S. Propylene carbonate also removes C2+ hydrocarbons, COS, SO2, CS2, and H2O…
This property of a fluid indicates its resistance to flow. It is a dynamic property, in that it can be measured only when the fluid…
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…
For sizing a horizontal separator it is necessary to choose a seam-toseam vessel length and a diameter. This choice must satisfy the conditions for gas…
An oscillating droplet of oil becomes unstable when the kinetic energy is sufficient to make up for the difference in the surface energy between the…
Tube holes cannot be drilled very close together, since this may structually weaken the tube sheet. The shortest distance between two adjacent tube holes is…
