Most oil treating on offshore facilities is done in vertical or horizontal treaters, such as those described in “Crude Oil Treating System“. Figure 2-8 is…
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…
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…
Sand can be very troublesome in separators by causing cutout of valve trim, plugging of separator internals, and accumulation in the bottom of the separator.…
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…
The Reynolds number is a dimensionless parameter that relates the ratio of inertial forces to viscous forces. It can be expressed by the following general…
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…
For most multi-well situations horizontal treaters are normally required. Figure 6-10 shows a typical design of a horizontal treater. Flow enters the front section of…
Most companies have a detailed general specification for the construction of pressure vessels, which defines the overall quality of fabrication required and addresses specific items…
There are many types of inlet diverters. Two main types are baffle plates (shown in Figure 4-6) and centrifugal diverters (shown in Figure 4-7). A…
