Water Treatment Process

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 example.

Lease Automatic Custudy Transfer

In large facilities oil is typically sold through a LACT unit, which is designed to meet API Standards and whatever additional measuring and sampling standards are required by the crude purchaser. The value received for the crude will typically depend … Continue reading

Oil Treating Process

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 an enlargement of the oil treater in Flow Sheet. In this case, a gas blanket … Continue reading

Process Separator Operating Pressure

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 made. For facilities handling less than 50,000 bpd, there are practical constraints that help limit … Continue reading

Stages Separation Selection

As more stages are added to the process there is less and less incremental liquid recovery. The diminishing income for adding a stage must more than offset the cost of the additional separator, piping, controls, space, and compressor complexities. It … Continue reading

Separation Stages

Figure 2-5 deals with a simple single-stage process. That is, the fluids are flashed in an initial separator and then the liquids from that separator are flashed again at the stock tank. Traditionally, the stock tank is not normally considered … Continue reading

Separator Initial Pressure

Because of the multicomponent nature of the produced fluid, the higher the pressure at which the initial separation occurs, the more liquid will be obtained in the separator. This liquid contains some light components that vaporize in the stock tank … Continue reading

Separation Flow Control

It is very rare that flow must be controlled in an oil field process. Normally, the control of pressure, level, and temperature is sufficient. Occasionally, it is necessary to assure that flow is split in some controlled manner between two … Continue reading

Separation Temperature Control

The way in which the process temperature is controlled varies. In a heater, a temperature controller measures the process temperature and signals a fuel valve to either let more or less fuel to the burner. In a heat exchanger the … Continue reading

Separator Level Control

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 dump valve. The most common form of level controller is a float, although electronic sensing … Continue reading
